QGIS Browser

The QGIS Browser is a panel in QGIS that lets you easily navigate in your database. You can have access to common vector files (e.g. ESRI shapefile or MapInfo files), databases (e.g.PostGIS, Oracle, Spatialite or MSSQL Spatial) and WMS/WFS connections. You can also view your GRASS data (to get the data into QGIS see Integração com SIG GRASS).

QGIS browser as a standalone application nix

Use QGIS Browser to preview your data. The drag and drop function makes it easy to get your data into the Map view and the Map legend.

  1. Activate QGIS Browser: Right-click on the tool bar and click checkboxBrowser or select from Settings ‣ Panels.
  2. Arraste o painel para a janela de legenda.

  3. Click on the Browser tab.
  4. Procure em sua base de dados e escolha a pasta de shapefile qgis_sample_data.

  5. Press the Shift key and click on airports.shp and alaska.shp .
  6. Pressione o botão esquerdo do mouse e arraste e solte os arquivos para a tela do mapa.

  7. Clique com o botão direito do mouse em uma camada e escolha: guilabel: Definir CRS projeto da camada. Para mais informações veja: ref: label_projections.

  8. Click on mActionZoomFullExtent Zoom Full to make the layers visible.

There is a second browser available under Settings ‣ Panels. Additional functions like the mActionAddAdd Selected Layers and the mActionFilterFilter files function were inserted.

  1. Activate a second QGIS Browser: Right-click on the toolbar and click checkboxBrowser (2) .
  2. Arraste o painel para a janela de legenda.

  3. Navigate to the Browser (2) tab and browse for a shapefile in your file system.
  4. Select a file with the left mouse button. Now you can use the mActionAddAdd Selected Layers icon. Use the icon to be able to work with a file in QGIS without much effort.

QGIS automatically looks for the Coordinate Reference System (CRS) and zooms to the layer extent if you work in a blank QGIS project. If there are already files in your project the file just will be added and in case it has the same extent and CRS it will be visualized. If the file has got another CRS and layer extent you must first right-click on the layer and choose Set Project CRS from Layer. Then choose Zoom to Layer Extent.

The mActionFilterFilter files function works on a directory level. Browse to the folder where you want to filter files and give in a search word or a wildcard. The browser only shows matching filenames then, other data won’t be displayed then.

Também é possível executar o Navegador QGIS como uma aplicação padrão.

In figure_browser_standalone_metadata you can see the enhanced functionality of QGIS browser. The Param tab provides the details of your connection based datasets like PostGIS or MSSQL Spatial. The Metadata tab contains general information about the file (see Metadata Menu). With the Preview tab you can have a look at your files without importing them into your QGIS project. It’s also possible to preview the attributes of your files in the Attributes tab.
