Description
5 areas of New Caledonia covered by the SPOT6 satellite are available at 1.5 meters resolution (RGB + PIR), totaling 128,4 km². These 5 areas have been manually segmented and then classified by photo-interpretation according to two types of classification:

(i) classification of the bio-geophysical land cover, containing 6 different classes (buildings, bare soil, forest, low-density vegetation; water bodies, Shadows and Clouds);

(ii) classification of the land use divided into 15 distinct classes. Two levels of hierarchy have been established. The first level separates four classes: the urban fabric, the natural formation, the wetlands and the shadows and clouds. The second level is described in the file "NC_NomLU.png".

The SPOT6 data, recorded in the course of 2013-2014, have been radiometrically corrected and assembled into a mosaic. The data were provided as ortho-rectified tiles based on the local authorities' 10-meter DTM and projected according to the reference coordinate system RGCN91-93 / Lambert New Caledonia (EPSG:3163).

Results are provided as a GeoTIFF file for each area.

The goal of this dataset, is to prepare the set-up of an operational system for land use and land cover monitoring for the South Province territory of New Caledonia. (2020-11-17)
