File, Open Menu

Use this menu option (popup from File menu), or the icons on the main toolbar, to open a data set.  You must understand the types of data and select the correct one.

The program forces you to select the type of data because:

  • Open project
  • Open DEM
  • Open and merge DEMs--pick multiple DEMs in a single directory, and merge them on the fly.  To merge from multiple directories, use map library database
  • Open and merge DEM directories: pick the directories you want.  Cancel when you have them all the directories you want.
  • Open tiled Geotiff DEM: requires that GDAL be installed, and sends the TIFF import through GDAL to create a more mainstream Geotiff. Use this if the regular Open DEM fails.
  • Open image
  • Open image with multiple bands.  It is not error-trapped; you must insure
    • All bands must be integer values
    • They must have the same number of rows and columns, data spacing, and conver the same area
    • They will be in alphabetical order
