Info

Select the links entitled ‘DTED Format’ and save the tiles to disk. The tiles arenamed by the latitude of the southwest corner of the tile, for example ‘n49.dt1.Unfortunately, the DTED naming convention only includes the latitude and notthe longitude so the file names are not unique and you will have to manage thisissue when saving your files.To create the elevation listing, open the DTED file in PANCROMA TM . Afterchoosing the file, select ‘Display Files’ | ‘ Display DTED Image’. After a momenta rendering of the DEM will be presented. In order to create the listing, select‘File’ | ‘Save Index File’ | ‘SRTM DTED File’. PANCROMA will present a datainput box for inputting the row and column ranges to include in the index fileoutput. The default is the entire image. If you wish to output only a portion of theDTED file, input the start and ending rows and columns in the text boxesprovided. Then click ‘OK’ . It will take a minute or two to write out the rather largeASCII file.299
It will be saved as a .dat file. A portion of a typical listing is shown below:ASCII Data File for SRTM DTED1 Format 1-Degree QuadrangleSW Corner Coordinates: 49 degrees Latitude 12 degrees LongitudeHorizontal Datum: World Geodetic System (WGS 84)Vertical Datum: MSLDistance Between Latitude Postings (m) at SW corner is: 92.6748Distance Between Longitude Postings (m) at SW corner is: 60.9785X Coordinate Y Coordinate Elevation (m) Latitude Longitude____________ ____________ _____________ ________ _________0 0 777 50 120 1 767 50 12.00080 2 757 50 12.00170 3 750 50 12.00250 4 741 50 12.00330 5 734 50 12.00420 6 731 50 12.0050 7 719 50 12.00580 8 712 50 12.00670 9 706 50 12.00750 10 698 50 12.00830 11 695 50 12.00920 12 687 50 12.010 13 678 50 12.01080 14 672 50 12.01170 15 664 50 12.01250 16 661 50 12.01330 17 652 50 12.01420 18 640 50 12.0150 19 626 50 12.01580 20 616 50 12.01670 21 614 50 12.01750 22 612 50 12.01830 23 609 50 12.01920 24 616 50 12.020 25 621 50 12.02080 26 621 50 12.02170 27 629 50 12.02250 28 630 50 12.02330 29 637 50 12.02420 30 640 50 12.0250 31 643 50 12.02580 32 647 50 12.02670 33 648 50 12.02750 34 654 50 12.02830 35 658 50 12.02920 36 663 50 12.030 37 666 50 12.03080 38 673 50 12.03170 39 673 50 12.03250 40 677 50 12.0333 ...etc.PANCROMA TM can also output the file in JPEG, BMP or PNG format.
