Advanced Land Observing Satellite (ALOS) Phased Array type-L band Synthetic Aperture Radar (PALSAR) UK imagery

Level 1 Advanced Land Observing Satellite (ALOS) Phased Array type-L band Synthetic Aperture Radar (PALSAR) data were acquired from ESA by the Landmap project and processed to produce greyscale 8 and 32-bit geotiff imagery for the UK and Republic of Ireland from 2007-2009. The UK data are projected onto the British National Grid whereas the Republic of Ireland data are projected onto the Irish National Grid. PALSAR is an active microwave sensor using L-band (2GHz) frequency and produces various products of different resolutions and performance. PALSAR data can be acquired during day or night, increasing the temporal coverage of data for a particular spatial extent. PALSAR is also unaffected by cloud cover allowing a better coverage of satellite data.

PALSAR collects data in 4 different modes. 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.

  • Data availability and file format

    The data are available in geotiff format which can be opened in many earth observation image processing software including open/free software such as Erdas ER viewer and the freely available Basic ERS & Envisat (A)ATSR and Meris Toolbox (BEAM) or NEST (Next ESA SAR Toolbox). 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 (Fine Beam Single (FBS), Fine Beam Dual (FBD) and Polarimetric). 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.
