The GIS_GEOSPOT Format
The GIS-Geospot format supports the SPOTView® products, consisting of cartographic products, with a geocoded SPOT image background.
Key points of the format:
- modular structure (several layers of description)
- integration of commonly used vector formats, DTM & QL
- addition of ancillary description files to take into account the different listed cases
- tree-like organization of files
- upgradeable.
Several Geospot products can be provided on a single medium. The set of products on the medium constitute the "Geospot volume".
The GIS_GEOSPOT format defines this modular structure by means of description files. For each subset these files provide the main features of the product, and of its raster and vector files.
The file name suffixes are:
- DSC: Volume description file listing products and subsets
- REP: Report file, defining a subset. It gives the number of files in the subset and their names
- HDR and HDV: header files, defining features of raster and vector data
- RSC and VSC: source description files, defining the sources of raster and vector data: origin, context
- CLR: providing a color palette for raster image display
- STX: statistics file, holding information about the variations in different parameters of a raster image.
The only mandatory files are DSC, REP, HDR and BIL.
