Open ICGC plugin

Toolbar plugin QGIS “Open ICGC” that allows direct and quick access to the geoinformation of the ICGC

The Open ICGC plugin (v.1.1.8, 6/2022) is integrated into the store of the free QGIS program, which adds a new toolbar and allows direct and quick access to the geographic information of the ICGC as well as to the search by place names and addresses with just one click. The new connector is compatible with QGIS versions later than 3.10.

This connector facilitates both the online connection, for users who always want to work with the most up-to-date data, and the download, for users who need to work offline. The vector download maps have been styled to facilitate interpretation from QGIS.

Geoinformation layers by reference 

These layers are linked from the QGIS project and are therefore always up to date. Internet connection is required. They include the following information:

  • Cartographic slices (1:1,000, 1:2,000, 1:5,000, 1:10,000, 1:25,000, 1:50,000, 1:100,000, lidar).
  • Elevation models (2 m and 5 m).
  • Geological map 1:250,000.
  • Land cover map (time series).
  • Orthophotos: territorial orthophoto service, with the entire historical color and infrared series navigable by coverage over the years, including the provisional orthophoto of the current flight.
  • Raster topographic pyramid.
  • Temporary covers of frames in anaglyph stereo.
  • Territorial topographic reference (time series).
  • Topographic maps (1:50,000, 1:250,000).Administrative divisions (municipal capitals, municipalities, counties, vaguerías, provinces, limits of Catalonia at different scales).

Layers for download

The layers that are downloaded can be used without an internet connection but it is the user's responsibility to update them. They include the following information:

  • Topographic cartography 1:1,000 (vector).
  • Administrative divisions (vector).
  • Land cover map (vector and raster).
  • Geological maps: 1:25,000 (GT I), 1:50,000, 1:250,000 and Map for the prevention of geological risks 1:25,000 (GT VI) (vector).
  • Topographic maps: 1:25,000, 1:50,000, 1:100,000, 1:250,000, 1:500,000, 1:1,000,000, 1:2,000,000 (raster).
  • Elevation models (2 m and 5 m).
  • Current orthophoto and infrared (25 cm, 50 cm and 250 cm).
  • Territorial topographic reference (geopackage, CAD and raster formats).
  • Historical series of color and infrared orthophoto.

Photo library catalog

It allows you to consult the frames of the ICGC photo library catalog available at one point, filter them by a range of flight dates and load them to superimpose them on the cartography of your GIS projects, with the precision that the flight instrumentation would allow at each historical moment. 


Frame Identifier Query

Query from QGIS of frame and dates of the flight

The photo library catalog also allows viewing options for viewing anaglyph stereo images and flight orthorectification.

The plugin is available for download in the official QGIS store, and can be installed from the same program as any other connector, through the menu:
