12. Combining NextMap DTM and ARSF data Radiometrically corrected level 1b ATM/CASI data. Post -1992, scan line altitude and location data also recorded. Level 3, geometrically corrected flight line, shown in true-colour. The curvature of the image edges is due to pitch and roll of the platform. Use AZ software suite to do this correction and to extract required bands etc NextMap Britain DTM of the Tamar estuary

13. Data from ATM and CASI can be draped over the 3d NextMap DTM data. Combining NextMap DTM and ARSF data
