Fitur-fitur¶

Lihat data¶

You can view and overlay vector and raster data in different formats and projections without conversion to an internal or common format. Supported formats include:

• Spatially-enabled tables and views using PostGIS, SpatiaLite and MS SQL Spatial, Oracle Spatial, vector formats supported by the installed OGR library, including ESRI shapefiles, MapInfo, SDTS, GML and many more. See section Pekerjaan dengan Data Vektor.

• Format raster dan citra yang didukung dengan terpasangnya GDAL (Geospatial Data Abstraction Library) perpustakaan, seperti GeoTiff, ERDAS IMG, ArcInfo ASCII GRID, JPEG, PNG dan banyak lagi, lihat bagian Pekerjaan dengan Data Raster.

• Data raster dan vektor GRASS dari basis data GRASS (lokasi/mapset). Lihat bagian GRASS GIS Integration.

• Data spasial dalam jaringan sebagai Layanan OGC Web, termasuk WMS, WMTS, WCS, WFS, dan WFS-T. Lihat bagian Pekerjaan dengan Data OGC.

Jelajahi data dan menyusun peta¶

Anda dapat membuat peta interaktif dan mengeksplorasi data spasial dengan GUI yang ramah. Banyak alat yang tersedia di GUI termasuk:

• QGIS browser

• On-the-fly proyeksi ulang

• Pengelola DB

• Map composer

• Panel Peninjau

• Bookmark spasial

• Annotation tools

• Identifikasi/pilih fitur

• Sunting/lihat/cari atribut

• Data-defined feature labelling

• Alat simbologi vektor dan raster data-ditentukan

• Peta komposisi atlas dengan lapisan graticule

• North arrow scale bar and copyright label for maps

• Dukungan menyimpan dan mengembalikan proyek-proyek

Membuat, menyunting, mengelola dan ekspor data¶

You can create, edit, manage and export vector and raster layers in several formats. QGIS offers the following:

• Alat Digitalisasi yang didukung format OGR dan lapisan vektor GRASS

• Ability to create and edit shapefiles and GRASS vector layers

• Plugin Georeferencer ke geocode gambar

• GPS tools to import and export GPX format, and convert other GPS formats to GPX or down/upload directly to a GPS unit (On Linux, usb: has been added to list of GPS devices.)

• Dukungan memvisualisasikan dan mengedit data OpenStreetMap

• Ability to create spatial database tables from shapefiles with DB Manager plugin

• Peningkatan penanganan tabel basis data spasial

• Peralatan untuk mengelola tabel atribut vektor

• Opsi menyimpan cuplikan layar sebagai gambar ber-georeferensi.

• Alat DXF-Export dengan kemampuan ditingkatkan untuk mengekspor gaya dan plugin untuk melakukan fungsi CAD-like

Analyze data¶

You can perform spatial data analysis on spatial databases and other OGR- supported formats. QGIS currently offers vector analysis, sampling, geoprocessing, geometry and database management tools. You can also use the integrated GRASS tools, which include the complete GRASS functionality of more than 400 modules. (See section GRASS GIS Integration.) Or, you can work with the Processing Plugin, which provides a powerful geospatial analysis framework to call native and third-party algorithms from QGIS, such as GDAL, SAGA, GRASS and more. (See section Pengantar.)

Terbitkan peta di Internet¶

QGIS can be used as a WMS, WMTS, WMS-C or WFS and WFS-T client, and as a WMS, WCS or WFS server. (See section Pekerjaan dengan Data OGC.) Additionally, you can publish your data on the Internet using a webserver with UMN MapServer or GeoServer installed.

Extend QGIS functionality through plugins¶

QGIS can be adapted to your special needs with the extensible plugin architecture and libraries that can be used to create plugins. You can even create new applications with C++ or Python!

Python Console¶

For scripting, it is possible to take advantage of an integrated Python console, which can be opened from menu: Plugins ‣ Python Console. The console opens as a non-modal utility window. For interaction with the QGIS environment, there is the qgis.utils.iface variable, which is an instance of QgsInterface. This interface allows access to the map canvas, menus, toolbars and other parts of the QGIS application. You can create a script, then drag and drop it into the QGIS window and it will be executed automatically.

For further information about working with the Python console and programming QGIS plugins and applications, please refer to Pengembangan Cookbook PyQGIS.
