Dataset for the Land cover map (CatLC)

Complete set of images, aerial and satellite, for the creation of the Catalonia land cover map using Artificial Intelligence (AI) techniques

CatLC is a complete set of images, aerial and satellite, for the creation of the Catalonia land cover map using Artificial Intelligence (AI) techniques. The images contain data from the year 2018 at different frequencies and spatial resolutions.

All images in GeoTiff format are georeferenced at the same projection, WGS84 UTM31N, and covering the same geographical extension:

  • UTM X West: 240000.
  • UTM X East: 540000.
  • UTM Y North: 4780000.
  • UTM Y South: 4480000.

Dataset description

The content of the dataset is detailed below:

  • Orthophoto RGB: Orthophoto with the 3 visible RGB channels at 1-meter spatial resolution.
  • Orthophoto Infrared: Infrared channel at 1-meter spatial resolution.
  • Sentinel-1: Monthly and annual composition of radar amplitude image at 10-meter spatial resolution.
  • Sentinel-2: 10-channel Sentinel-2 image composition for the months of April and August at 10-meter spatial resolution.
  • Topographic data: 
    • Aspect: Orientation angle of terrain slopes, in degrees, at 5-meter spatial resolution.
    • CHM: Digital elevation model of different elements of the terrain, vegetation and buildings for example, referred to the terrain surface at 1-meter spatial resolution.
    • DEM: Digital Elevation Model at 5-meter spatial resolution.
    • DSM: Digital Surface Model at 1-meter spatial resolution.
    • Slope: Terrain slope, in degrees, at 5-meter spatial resolution.
  • Land cover: 41-class land cover map created by ICGC at 1-meter spatial resolution. This layer can be used for training and validation when processing with different AI techniques.
