DESCRIPTION

DTI2IIS is a utility to convert raster data in a Laser Scan Digital Terrain Image (DTI) file to International Imaging System's (IIS) system 500 format. System 500 data files are composed of swaths, each 512 bytes in width. These swaths run from the top of the image to the bottom. The data order within the file is the top row of the first swath followed consecutively by the rest of the swath. This is then repeated for each swath in turn until the whole width of the image is covered. It should be remembered that the number of actual values per swath width will depend upon the data type in the file, (i.e. 512 BYTE values, 256 INTEGER*2 values and 128 INTEGER*4 values).

EXAMPLES

 $ DTI2IIS COVERMAP COVERMAP /SHORT

In this example, a data value in the IIS file is held and converted as a short integer. A DTI file containing word data will be created. The informational messages provide continual reassurance of the extent of the conversion. It can be seen that the IIS file is written out one swath at a time. As the data in this example is INTEGER*2 the swath width is 256 values wide (512 bytes) and so two swaths are needed to cover the data area.
