3. Services¶

QGIS Server is able to serve data according to standard protocols as described by the Open Geospatial Consortium (OGC):

WMS 1.1.0 and 1.3.0
WFS 1.0.0, 1.1.0, 2.0
OGC API - Features (WFS3)
WCS 1.1.1
WMTS 1.0.0

Extra vendor parameters and requests are supported in addition to the original standard that greatly enhance the possibilities of customizing its behavior thanks to the QGIS rendering engine.

3.1. Web Map Service (WMS)¶

The 1.1.0 and 1.3.0 WMS standards implemented in QGIS Server provide a HTTP interface to request map or legend images generated from a QGIS project. A typical WMS request defines the QGIS project to use, the layers to render as well as the image format to generate. Basic support is also available for Styled Layer Descriptor (SLD).

Specifications:

Standard requests provided by QGIS Server:

Request	Description
GetCapabilities	Returns XML metadata with information about the server
GetMap	Returns a map
GetFeatureInfo	Retrieves data (geometry and values) for a pixel location
GetLegendGraphics	Returns legend symbols

Vendor requests provided by QGIS Server:

Request	Description
GetPrint	Returns a QGIS composition
GetProjectSettings	Returns specific information about QGIS Server

3.1.1. GetMap ¶

URL example:

http://localhost/qgis_server?
SERVICE=WMS
&VERSION=1.3.0
&REQUEST=GetMap
&MAP=/home/qgis/projects/world.qgs
&LAYERS=mylayer1,mylayer2,mylayer3
&STYLES=style1,default,style3
&OPACITIES=125,200,125
&CRS=EPSG:4326
&WIDTH=400
&HEIGHT=400
&FORMAT=image/png
&TRANSPARENT=TRUE
&DPI=300
&TILED=TRUE

3.1.1.1. SERVICE¶

This parameter has to be WMS in case of the GetMap request.

3.1.1.2. VERSION¶

This parameter allows to specify the version of the service to use. Available values for the VERSION parameter are:

1.1.0
1.3.0

If no version is indicated in the request, then 1.3.0 is used by default.

According to the version number, slight differences have to be expected as explained later for the next parameters:

CRS / SRS
BBOX

3.1.1.3. REQUEST¶

This parameter is GetMap in case of the GetMap request.

3.1.1.4. LAYERS¶

This parameter allows to specify the layers to display on the map. Names have to be separated by a comma.

In addition, QGIS Server introduced some options to select layers by:

a short name
the layer id

The short name of a layer may be configured through Properties ‣ Metadata in layer menu. If the short name is defined, then it’s used by default instead of the layer’s name:

http://localhost/qgisserver?
SERVICE=WMS
&REQUEST=GetMap
&LAYERS=mynickname1,mynickname2
&...

Moreover, there’s a project option allowing to select layers by their id in OWS Server ‣ WMS capabilities menu of the Project ‣ Properties… dialog. To activate this option, the checkbox Use layer ids as names has to be selected.

http://localhost/qgisserver?
SERVICE=WMS
&REQUEST=GetMap
&LAYERS=mylayerid1,mylayerid2
&...

3.1.1.5. STYLES¶

This parameter can be used to specify a layer’s style for the rendering step. Styles have to be separated by a comma. The name of the default style is default.

3.1.1.6. SRS / CRS¶

This parameter allows to indicate the map output Spatial Reference System in WMS 1.1.0 and has to be formed like EPSG:XXXX. Note that CRS is also supported if current version is 1.1.0.

For WMS 1.3.0, CRS parameter is preferable but SRS is also supported.

Note that if both CRS and SRS parameters are indicated in the request, then it’s the current version indicated in VERSION parameter which is decisive.

In the next case, the SRS parameter is kept whatever the VERSION parameter because CRS is not indicated:

http://localhost/qgisserver?
SERVICE=WMS
&REQUEST=GetMap
&VERSION=1.3.0
&SRS=EPSG:2854
&...

In the next case, the SRS parameter is kept instead of CRS because of the VERSION parameter:

http://localhost/qgisserver?
SERVICE=WMS
&REQUEST=GetMap
&VERSION=1.1.0
&CRS=EPSG:4326
&SRS=EPSG:2854
&...

In the next case, the CRS parameter is kept instead of SRS because of the VERSION parameter:

http://localhost/qgisserver?
SERVICE=WMS
&REQUEST=GetMap
&VERSION=1.3.0
&CRS=EPSG:4326
&SRS=EPSG:2854
&...

3.1.1.7. BBOX¶

This parameter allows to specify the map extent with units according to the current CRS. Coordinates have to be separated by a comma.

However, a slight difference has to be noticed according to the current VERSION parameter. In WMS 1.1.0, coordinates are formed like minx,miny,maxx,maxy or minlong,minlat,maxlong,maxlat. For example:

http://localhost/qgisserver?
SERVICE=WMS
&REQUEST=GetMap
&VERSION=1.1.0
&SRS=epsg:4326
&BBOX=-180,-90,180,90
&...

But the axis is reversed in WMS 1.3.0, so coordinates are formed like: miny,minx,maxy,maxx or minlat,minlong,maxlat,maxlong. For example:

http://localhost/qgisserver?
SERVICE=WMS
&REQUEST=GetMap
&VERSION=1.3.0
&CRS=epsg:4326
&BBOX=-90,-180,90,180
&...

3.1.1.8. WIDTH¶

This parameter allows to specify the width in pixels of the output image.

3.1.1.9. HEIGHT¶

This parameter allows to specify the height in pixels of the output image.

3.1.1.10. FORMAT¶

This parameter may be used to specify the format of map image. Available values are:

jpg
jpeg
image/jpeg
image/png
image/png; mode=1bit
image/png; mode=8bit
image/png; mode=16bit

application/dxf Only layers that have read access in the WFS service are exported in the DXF format.

URL example:

http://localhost/qgisserver?
SERVICE=WMS&VERSION=1.3.0
&REQUEST=GetMap
&FORMAT=application/dxf
&LAYERS=Haltungen,Normschacht,Spezialbauwerke
&STYLES=
&CRS=EPSG%3A21781&BBOX=696136.28844801,245797.12108743,696318.91114315,245939.25832905
&WIDTH=1042
&HEIGHT=811
&FORMAT_OPTIONS=MODE:SYMBOLLAYERSYMBOLOGY;SCALE:250&FILE_NAME=plan.dxf

3.1.1.11. TRANSPARENT¶

This boolean parameter can be used to specify the background transparency. Available values are (not case sensitive):

TRUE
FALSE

However, this parameter is ignored if the format of the map image indicated with FORMAT is different from PNG.

3.1.1.12. MAP¶

This parameter allows to define the QGIS project file to use.

As mentioned in GetMap parameters table, MAP is mandatory because a request needs a QGIS project to actually work. However, the QGIS_PROJECT_FILE environment variable may be used to define a default QGIS project. In this specific case, MAP is not longer a required parameter. For further information you may refer to Advanced configuration.

3.1.1.13. BGCOLOR¶

This parameter allows to indicate a background color for the map image. However it cannot be combined with TRANSPARENT parameter in case of PNG images (transparency takes priority). The colour may be literal or in hexadecimal notation.

URL example with the literal notation:

http://localhost/qgisserver?
SERVICE=WMS
&REQUEST=GetMap
&VERSION=1.3.0
&BGCOLOR=green
&...

URL example with the hexadecimal notation:

http://localhost/qgisserver?
SERVICE=WMS
&REQUEST=GetMap
&VERSION=1.3.0
&BGCOLOR=0x00FF00
&...

3.1.1.14. DPI¶

This parameter can be used to specify the requested output resolution.

3.1.1.15. IMAGE_QUALITY¶

This parameter is only used for JPEG images. By default, the JPEG compression is -1.

You can change the default per QGIS project in the OWS Server ‣ WMS capabilities menu of the Project ‣ Properties… dialog. If you want to override it in a GetMap request you can do it using the IMAGE_QUALITY parameter.

3.1.1.16. OPACITIES¶

Opacity can be set on layer or group level. Allowed values range from 0 (fully transparent) to 255 (fully opaque).

3.1.1.17. FILTER¶

A subset of layers can be selected with the FILTER parameter. The syntax is basically the same as for the QGIS subset string. However, there are some restrictions to avoid SQL injections into databases via QGIS Server. If a dangerous string is found in the parameter, QGIS Server will return the next error:

<ServiceExceptionReport>
  <ServiceException code="Security">The filter string XXXXXXXXX has been rejected because of security reasons.
  Note: Text strings have to be enclosed in single or double quotes. A space between each word / special character is mandatory.
  Allowed Keywords and special characters are IS,NOT,NULL,AND,OR,IN,=,<,=<,>,>=,!=,',',(,),DMETAPHONE,SOUNDEX.
  Not allowed are semicolons in the filter expression.</ServiceException>
</ServiceExceptionReport>

URL example:

http://localhost/qgisserver?
SERVICE=WMS
&REQUEST=GetMap
&LAYERS=mylayer1,mylayer2,mylayer3
&FILTER=mylayer1:"col1";mylayer1,mylayer2:"col2" = 'blabla'
&...

In this example, the same filter (field col2 equals the string blabla) is applied to layers mylayer1 and mylayer2, while the filter on col1 is only applied to mylayer1.

Note

It is possible to make attribute searches via GetFeatureInfo and omit the X/Y parameter if a FILTER is there. QGIS Server then returns info about the matching features and generates a combined bounding box in the XML output.

3.1.1.18. SELECTION¶

The SELECTION parameter can highlight features from one or more layers. Vector features can be selected by passing comma separated lists with feature ids.

http://localhost/qgisserver?
SERVICE=WMS
&REQUEST=GetMap
&LAYERS=mylayer1,mylayer2
&SELECTION=mylayer1:3,6,9;mylayer2:1,5,6
&...

The following image presents the response from a GetMap request using the SELECTION option e.g. http://myserver.com/...&SELECTION=countries:171,65.

As those features id’s correspond in the source dataset to France and Romania they’re highlighted in yellow.

../../_images/server_selection_parameter.png

Fig. 3.1 Server response to a GetMap request with SELECTION parameter¶

3.1.1.19. TILED¶

For performance reasons, QGIS Server can be used in tiled mode. In this mode, the client requests several small fixed size tiles, and assembles them to form the whole map. Doing this, symbols at or near the boundary between two tiles may appeared cut, because they are only present in one of the tile.

Set the TILED parameter to TRUE to tell QGIS Server to work in tiled mode, and to apply the Tile buffer configured in the QGIS project (see Configure your project).

When TILED is TRUE and when a non-zero Tile buffer is configured in the QGIS project, features outside the tile extent are drawn to avoid cut symbols at tile boundaries.

TILED defaults to FALSE.

3.1.2. GetFeatureInfo ¶

Content based legend. These parameters let the client request a legend showing only the symbols for the features falling into the requested area:

BBOX the geographical area for which the legend should be built
CRS / SRS the coordinate reference system adopted to define the BBOX coordinates
WIDTH / HEIGHT if set these should match those defined for the GetMap request, to let QGIS Server scale symbols according to the map view image size.

Content based legend features are based on the UMN MapServer implementation:

SHOWFEATURECOUNT if set to TRUE adds in the legend the feature count of the features like in the following image:
RULE set it to a given rule name to get only the named rule symbol

3.1.5. GetProjectSettings ¶

In addition to the standard ones, QGIS Server supports the following extra parameters:

Parameter	Required	Description
MAP	Yes	Specify the QGIS project file

URL example:

http://localhost/qgisserver?
SERVICE=WMTS
&REQUEST=GetTile
&MAP=/home/qgis/projects/world.qgs
&LAYER=mylayer
&FORMAT=image/png
&TILEMATRIXSET=EPSG:4326
&TILEROW=0
&TILECOL=0

3.3.2.1. SERVICE¶

This parameter has to be WMTS in case of the GetTile request.

3.3.2.2. REQUEST¶

This parameter is GetTile in case of the GetTile request.

3.3.2.3. LAYER¶

This parameter allows to specify the layer to display on the tile.

In addition, QGIS Server introduced some options to select a layer by:

a short name
the layer id

The short name of a layer may be configured through Properties ‣ Metadata in layer menu. If the short name is defined, then it’s used by default instead of the layer’s name:

http://localhost/qgisserver?
SERVICE=WMTS
&REQUEST=GetTile
&LAYER=mynickname
&...

Moreover, there’s a project option allowing to select layers by their id in OWS Server ‣ WMS capabilities menu of the Project ‣ Project Properties dialog. To activate this option, the checkbox Use layer ids as names has to be selected.

http://localhost/qgisserver?
SERVICE=WMTS
&REQUEST=GetTile
&LAYER=mylayerid1
&...

3.3.2.4. FORMAT¶

This parameter may be used to specify the format of tile image. Available values are:

jpg
jpeg
image/jpeg
image/png

If the FORMAT parameter is different from one of these values, then the default format PNG is used instead.

3.3.2.5. TILEMATRIXSET¶

This parameter defines the CRS to use when computing the underlying pyramid. Format: EPSG:XXXX.

3.3.2.6. TILEMATRIX¶

This parameter allows to define the matrix to use for the output tile.

3.3.2.8. TILECOL¶

This parameter allows to select the column of the tile to get within the matrix.

3.3.2.9. MAP¶

This parameter allows to define the QGIS project file to use.

As mentioned in GetMap parameters table, MAP is mandatory because a request needs a QGIS project to actually work. However, the QGIS_PROJECT_FILE environment variable may be used to define a default QGIS project. In this specific case, MAP is not longer a required parameter. For further information you may refer to Advanced configuration.

3.3.3. GetFeatureInfo ¶

For further information you may refer to Advanced configuration.

3.3.3.4. LAYER¶

This parameter allows to specify the layer to display on the tile.

In addition, QGIS Server introduced some options to select a layer by:

a short name
the layer id

The short name of a layer may be configured through Properties ‣ Metadata in layer menu. If the short name is defined, then it’s used by default instead of the layer’s name:

http://localhost/qgisserver?
SERVICE=WMTS
&REQUEST=GetFeatureInfo
&LAYER=mynickname
&...

Moreover, there’s a project option allowing to select layers by their id in OWS Server ‣ WMS capabilities menu of the Project ‣ Project Properties dialog. To activate this option, the checkbox Use layer ids as names has to be selected.

http://localhost/qgisserver?

3.4. WFS3 (OGC API Features)¶

WFS3 is the first implementation of the new generation of OGC protocols. It is described by the OGC API - Features - Part 1: Core document.

Here is a quick informal summary of the most important differences between the well known WFS protocol and WFS3:

WFS3 is based on a REST API
WFS3 API must follow the OPENAPI specifications
WFS3 supports multiple output formats but it does not dictate any (only GeoJSON and HTML are currently available in QGIS WFS3) and it uses content negotiation to determine which format is to be served to the client
JSON and HTML are first class citizens in WFS3
WFS3 is self-documenting (through the /api endpoint)
WFS3 is fully navigable (through links) and browsable

Important

While the WFS3 implementation in QGIS can make use of the MAP parameter to specify the project file, no extra query parameters are allowed by the OPENAPI specification. For this reason it is strongly recommended that MAP is not exposed in the URL and the project file is specified in the environment by other means (i.e. setting QGIS_PROJECT_FILE in the environment through a web server rewrite rule).

Note

The API endpoint provides comprehensive documentation of all supported parameters and output formats of your service. The following paragraphs will only describe the most important ones.

3.4.1. Resource representation ¶

The QGIS Server WFS3 implementation currently supports the following resource representation (output) formats:

HTML
JSON

The format that is actually served will depend on content negotiation, but a specific format can be explicitly requested by appending a format specifier to the endpoints.

Supported format specifier extensions are:

.json
.html

Additional format specifier aliases may be defined by specific endpoints:

.openapi: alias for .json supported by the API endpoint
.geojson: alias for .json supported by the Features and Feature endpoints

3.4.2. Endpoints ¶

The API provides a list of endpoints that the clients can retrieve. The system is designed in such a way that every response provides a set of links to navigate through all the provided resources.

Endpoints points provided by the QGIS implementation are:

Name	Path	Description
Landing Page	`/`	General information about the service and provides links to all available endpoints
Conformance	`/conformance`	Information about the conformance of the service to the standards
API	`/api`	Full description of the endpoints provided by the service and the returned documents structure
Collections	`/collections`	List of all collections (i.e. ‘vector layers’) provided by the service
Collection	`/collections/{collectionId}`	Information about a collection (name, metadata, extent etc.)
Features	`/collections/{collectionId}/items`	List of the features provided by the collection
Feature	`/collections/{collectionId}/items/{featureId}`	Information about a single feature

3.4.2.1. Landing Page¶

The main endpoint is the Landing Page. From that page it is possible to navigate to all the available service endpoints. The Landing Page must provide links to

the API definition (path /api link relations service-desc and service-doc),
the Conformance declaration (path /conformance, link relation conformance), and
the Collections (path /collections, link relation data).

../../_images/server_wfs3_landing_page.png

Fig. 3.2 Server WFS3 landing page¶

3.4.2.2. API Definition¶

The API Definition is an OPENAPI-compliant description of the API provided by the service. In its HTML representation it is a browsable page where all the endpoints and their response formats are accurately listed and documented. The path of this endpoint is /api.

The API definition provides a comprehensive and authoritative documentation of the service, including all supported parameters and returned formats.

Note

This endpoint is analogue to WFS’s GetCapabilities

3.4.2.3. Collections list¶

The collections endpoint provides a list of all the collections available in the service. Since the service “serves” a single QGIS project the collections are the vector layers from the current project (if they were published as WFS in the project properties). The path of this endpoint is /collections/.

../../_images/server_wfs3_collections.png

Fig. 3.3 Server WFS3 collections list page¶

3.4.2.4. Collection detail¶

While the collections endpoint does not provide detailed information about each available collection, that information is available in the /collections/{collectionId} endpoints. Typical information includes the extent, a description, CRSs and other metadata.

The HTML representation also provides a browsable map with the available features.

../../_images/server_wfs3_collection.png

Fig. 3.4 Server WFS3 collection detail page¶

3.4.2.5. Features list¶

This endpoint provides a list of all features in a collection knowing the collection ID. The path of this endpoint is /collections/{collectionId}/items.

The HTML representation also provides a browsable map with the available features.

Note

This endpoint is analogue to GetFeature in WFS 1 and WFS 2.

Fig. 3.5 Server WFS3 features list page¶

3.4.2.6. Feature detail¶

This endpoint provides all the available information about a single feature, including the feature attributes and its geometry. The path of this endpoint is /collections/{collectionId}/items/{itemId}.

The HTML representation also provides a browsable map with the feature geometry.

Fig. 3.6 Server WFS3 feature detail page¶

3.4.3. Pagination ¶

Pagination of a long list of features is implemented in the OGC API through next and prev links, QGIS server constructs these links by appending limit and offset as query string parameters.

URL example:

http://localhost/qgisserver/wfs3/collection_one/items.json?offset=10&limit=10

Note

The maximum acceptable value for limit can be configured with the QGIS_SERVER_API_WFS3_MAX_LIMIT server configuration setting (see: Environment variables).

3.4.4. Feature filtering ¶

The features available in a collection can be filtered/searched by specifying one or more filters.

3.4.4.1. Date and time filter¶

Collections with date and/or datetime attributes can be filtered by specifying a datetime argument in the query string. By default the first date/datetime field is used for filtering. This behavior can be configured by setting a “Date” or “Time” dimension in the QGIS Server ‣ Dimension section of the layer properties dialog.

The date and time filtering syntax is fully described in the API Definition and also supports ranges (begin and end values are included) in addition to single values.

URL examples:

Returns only the features with date dimension matching 2019-01-01

http://localhost/qgisserver/wfs3/collection_one/items.json?datetime=2019-01-01

Returns only the features with datetime dimension matching 2019-01-01T01:01:01

http://localhost/qgisserver/wfs3/collection_one/items.json?datetime=2019-01-01T01:01:01

Returns only the features with datetime dimension in the range 2019-01-01T01:01:01 - 2019-01-01T12:00:00

http://localhost/qgisserver/wfs3/collection_one/items.json?datetime=2019-01-01T01:01:01/2019-01-01T12:00:00

3.4.4.2. Bounding box filter¶

A bounding box spatial filter can be specified with the bbox parameter:

The order of the comma separated elements is:

Lower left corner, WGS 84 longitude
Lower left corner, WGS 84 latitude
Upper right corner, WGS 84 longitude
Upper right corner, WGS 84 latitude

Note

The OGC specifications also allow a 6 item bbox specifier where the third and sixth items are the Z components, this is not yet supported by QGIS server.

URL example:

http://localhost/qgisserver/wfs3/collection_one/items.json?bbox=-180,-90,180,90

If the CRS of the bounding box is not WGS 84, a different CRS can be specified by using the optional parameter bbox-crs. The CRS format identifier must be in the OGC URI format:

URL example:

http://localhost/qgisserver/wfs3/collection_one/items.json?bbox=913191,5606014,913234,5606029&bbox-crs=http://www.opengis.net/def/crs/EPSG/9.6.2/3857

3.4.5. Feature sorting `NEW in 3.16`¶

It is possible to order the result set by field value using the sortby query parameter.

The results are sorted in ascending order by default. To sort the results in descending order, a boolean flag (sortdesc) can be set:

http://localhost/qgisserver/wfs3/collection_one/items.json?sortby=name&sortdesc=1

3.4.6. Attribute selection ¶

The feature attributes returned by a Features list call can be limited by adding a comma separated list of attribute names in the optional properties query string argument.

URL example:

returns only the name attribute

http://localhost/qgisserver/wfs3/collection_one/items.json?properties=name

3.4.7. The HTML template language ¶

The HTML representation uses a set of HTML templates to generate the response. The template is parsed by a template engine called inja. The templates can be customized by overriding them (see: Template overrides). The template has access to the same data that are available to the JSON representation and a few additional functions are available to the template:

3.4.7.1. Custom template functions¶

path_append( path ): appends a directory path to the current url
path_chomp( n ): removes the specified number “n” of directory components from the current url path
json_dump( ): prints the JSON data passed to the template
static( path ): returns the full URL to the specified static path. For example: “static( “/style/black.css” )” with a root path “http://localhost/qgisserver/wfs3” will return “http://localhost/qgisserver/wfs3/static/style/black.css”.
links_filter( links, key, value ): Returns filtered links from a link list
content_type_name( content_type ): Returns a short name from a content type, for example “text/html” will return “HTML”

3.4.7.2. Template overrides¶

Templates and static assets are stored in subdirectories of the QGIS server default API resource directory (/usr/share/qgis/resources/server/api/ on a Linux system), the base directory can be customized by changing the environment variable QGIS_SERVER_API_RESOURCES_DIRECTORY.

A typical Linux installation will have the following directory tree:

/usr/share/qgis/resources/server/api/
└── ogc
    ├── schema.json
    ├── static
    │   ├── jsonFormatter.min.css
    │   ├── jsonFormatter.min.js
    │   └── style.css
    └── templates
        └── wfs3
            ├── describeCollection.html
            ├── describeCollections.html
            ├── footer.html
            ├── getApiDescription.html
            ├── getFeature.html
            ├── getFeatures.html
            ├── getLandingPage.html
            ├── getRequirementClasses.html
            ├── header.html
            ├── leaflet_map.html
            └── links.html

To override the templates you can copy the whole tree to another location and point QGIS_SERVER_API_RESOURCES_DIRECTORY to the new location.

3.5. Extra parameters supported by all request types ¶

The following extra parameters are supported by all protocols.

FILE_NAME: if set, the server response will be sent to the client as a file attachment with the specified file name.

Note

Not available for WFS3.

MAP: Similar to MapServer, the MAP parameter can be used to specify the path to the QGIS project file. You can specify an absolute path or a path relative to the location of the server executable (qgis_mapserv.fcgi). If not specified, QGIS Server searches for .qgs files in the directory where the server executable is located.

Example:
```
http://localhost/cgi-bin/qgis_mapserv.fcgi?\
  REQUEST=GetMap&MAP=/home/qgis/projects/world.qgs&...
```

Note

You can define a QGIS_PROJECT_FILE as an environment variable to tell the server executable where to find the QGIS project file. This variable will be the location where QGIS will look for the project file. If not defined it will use the MAP parameter in the request and finally look at the server executable directory.

3.6. REDLINING ¶

This feature is available and can be used with GetMap and GetPrint requests.

The redlining feature can be used to pass geometries and labels in the request which are overlapped by the server over the standard returned image (map). This permits the user to put emphasis or maybe add some comments (labels) to some areas, locations etc. that are not in the standard map.

The request is in the format:

http://qgisplatform.demo/cgi-bin/qgis_mapserv.fcgi?map=/world.qgs&SERVICE=WMS&VERSION=1.3.0&
REQUEST=GetMap
...
&HIGHLIGHT_GEOM=POLYGON((590000 5647000, 590000 6110620, 2500000 6110620, 2500000 5647000, 590000 5647000))
&HIGHLIGHT_SYMBOL=<StyledLayerDescriptor><UserStyle><Name>Highlight</Name><FeatureTypeStyle><Rule><Name>Symbol</Name><LineSymbolizer><Stroke><SvgParameter name="stroke">%23ea1173</SvgParameter><SvgParameter name="stroke-opacity">1</SvgParameter><SvgParameter name="stroke-width">1.6</SvgParameter></Stroke></LineSymbolizer></Rule></FeatureTypeStyle></UserStyle></StyledLayerDescriptor>
&HIGHLIGHT_LABELSTRING=Write label here
&HIGHLIGHT_LABELSIZE=16
&HIGHLIGHT_LABELCOLOR=%23000000
&HIGHLIGHT_LABELBUFFERCOLOR=%23FFFFFF
&HIGHLIGHT_LABELBUFFERSIZE=1.5

Here is the image outputed by the above request in which a polygon and a label are drawn on top of the normal map:

Fig. 3.7 Server response to a GetMap request with redlining parameters¶

You can see there are several parameters in this request:

HIGHLIGHT_GEOM: You can add POINT, MULTILINESTRING, POLYGON etc. It supports multipart geometries. Here is an example: HIGHLIGHT_GEOM=MULTILINESTRING((0 0, 0 1, 1 1)). The coordinates should be in the CRS of the GetMap/GetPrint request.
HIGHLIGHT_SYMBOL: This controls how the geometry is outlined and you can change the stroke width, color and opacity.
HIGHLIGHT_LABELSTRING: You can pass your labeling text to this parameter.
HIGHLIGHT_LABELSIZE: This parameter controls the size of the label.
HIGHLIGHT_LABELFONT: This parameter controls the font of the label (e.g. Arial)
HIGHLIGHT_LABELCOLOR: This parameter controls the label color.
HIGHLIGHT_LABELBUFFERCOLOR: This parameter controls the label buffer color.
HIGHLIGHT_LABELBUFFERSIZE: This parameter controls the label buffer size.

3.7. External WMS layers ¶

QGIS Server allows including layers from external WMS servers in WMS GetMap and WMS GetPrint requests. This is especially useful if a web client uses an external background layer in the web map. For performance reasons, such layers should be directly requested by the web client (not cascaded via QGIS server). For printing however, these layers should be cascaded via QGIS server in order to appear in the printed map.

External layers can be added to the LAYERS parameter as EXTERNAL_WMS:<layername>. The parameters for the external WMS layers (e.g. url, format, dpiMode, crs, layers, styles) can later be given as service parameters <layername>:<parameter>. In a GetMap request, this might look like this:

http://localhost/qgisserver?
SERVICE=WMS&REQUEST=GetMap
...
&LAYERS=EXTERNAL_WMS:basemap,layer1,layer2
&STYLES=,,
&basemap:url=http://externalserver.com/wms.fcgi
&basemap:format=image/jpeg
&basemap:dpiMode=7
&basemap:crs=EPSG:2056
&basemap:layers=orthofoto
&basemap:styles=default

Similarly, external layers can be used in GetPrint requests:

http://localhost/qgisserver?
SERVICE=WMS
...
&REQUEST=GetPrint&TEMPLATE=A4
&map0:layers=EXTERNAL_WMS:basemap,layer1,layer2
&map0:EXTENT=<minx,miny,maxx,maxy>
&basemap:url=http://externalserver.com/wms.fcgi
&basemap:format=image/jpeg
&basemap:dpiMode=7
&basemap:crs=EPSG:2056
&basemap:layers=orthofoto
&basemap:styles=default
