After navigation and selecting your area of interest, you can save both the imagefile and the elevation files separately. These can be used by other applicationslike the excellent 3DEM for preparing terrain models by draping the image overthe elevation model.A major issue with this data is that the elevation files are saved mirror flippedaround the center latitude line. PANCROMA TM has a utility for correcting thisproblem. The elevation data is saved in GeoTiff format using IEEE floating point32 bit representations for the elevation postings. To produce a corrected file,select ‘File’ | ‘Open’ and open the elevation file. Then select ‘Display Files’ |‘Display GeoTiff IEEE FP 32 Elevation Image’ | ‘Flipped’. A rendering of theprocessed file will appear. You can save the file by selecting ‘File’ | ‘SaveGrayscale Image’ | ‘GeoTiff’. The file will be saved as a GeoTiff DEM (not araster image). Examples of a file as downloaded from WorldWind and acorrected file are shown below.118
