- “Cornwall From Space” is a glossy printed image at a scale of 1:200,000 from M-Sat Ltd. The photographs are taken from the visible spectrum images of Landsat 5 at a height of 705.5km with a resolution of 30m. Similar (the same?) pictures are also available from a French company called IMSAT (Link broken 9 Sep 2002).
- The “Cornwall Satellite Image Map” CDROM from the NPA Group is an infra-red Landsat TM image with a 30m resolution. Using the suplied viewer, there is an overlay of the Ordnance Survey Net-Map™ which can show the coast, district boundaries, roads, railways and population centre names. This is an interesting but rather specialised view of the ground.
- getmapping.com is producing a mosaic composite picture of the UK using conventional aircraft strip flying techniques to give a resolution of about 10cm. The website allows you to browse around the country using postcode searches and “joystick” type controls. The pictures are available in printed “Certificates” which will include images 0.5km square. They are also publishing a facsimile copy of the Domesday Book and certificates containing extracts.
- “Window on the UK 2000” on CDROM produced by the British National Space Centre was given away free with the Sunday Times Newspaper on 9 Apr 2000. At the time of publication further copies could be obtained by post from the BNSC. Various parts of the CD were taken from different satellites and other formats. Cornwall seems to be mostly from Landsat TM and an extract for West Penwith has been converted to JPG format (58K) without too great a loss in quality.
