The raw data for the alternating polarisation, wide swath and image modes were acquired by the Landmap project from ESA and processed to produce 8 and 32-bit greyscale and multi-difference colour composite geotiff images. The Joint Information Systems Committee (JISC) funded Landmap service which ran from 2001 to July 2014 collected and hosted a large amount of earth observation data for the majority of the UK. After removal of JISC funding in 2013, the Landmap service is no longer operational, with the data now held at the NEODC.

Geotiff files are TIFF files which have geographic metadata embedded as tags within the TIFF file. The geographic metadata can then be used to position the image in the correct location and geometry on the screen of a geographic information display. The data are split into the three modes acquired by Landmap (alternating polarisation, wide swath and image modes). The various polarisations can be determined from the filename: hh - Horizontal polarisation transmitted, horizontal received. vv - Vertical transmitted, vertical received hv - Horizontal transmitted, vertical received vh - Vertical transmitted, horizontal received Specific products include 32 bit _geo GeoTiff, and 8 bit _geo_lia and _geo_ls_mask GeoTiffs. All the geotiff images are provided with GeoTiff World Files (.tfw) which are used to geo-reference images to an appropriate projection scheme.
