Supported Raster File Formats

These are the supported file formats for Raster File Conversions. After data has been imported, the Output File Extension drop-down list will be automatically limited to file types that are compatible with the loaded data type.

Note: If a file type includes supporting files, all associated files must be loaded. See the list of supported reference files below.
Common Name Read Write Extension
Arc/Info Ascii Grid *.asc
Bitmap *.bmp
USGS ASCII DEM *.dem
Enhanced Compressed Wavelet *.ecw
JPEG *.jpg
JPEG 2000 *.jp2, *.jpf
MrSID   *.sid
Portable Network Graphics *.png
TIFF and GeoTIFF *.tiff

Supporting Reference Files

Some raster file types require other reference files to be loaded concurrently. These additional reference files can include (but are not limited to) the following:

  • .rsf (from Geographic Calculator Desktop),
  • .prj
  • world files (first and last letter of format name, with “w” added to the end. E.g. JPG = “jgw”)
  • .tab (for some formats only)
