Valid Imagery Formats

You can convert the following external file formats to a format supported by STK using one of the STK image converters.

*.bmp
*.clds
*.ecw
*.img
*.jp2 (JPEG 2000)
*.jpg
*.jpeg
*.lbl
*.ntf (NITF)
*.pgm
*.png
*.ppm (Binary Only)
*.sid (MrSID)
*.tga
*.tif GeoTIFF
*.tiff GeoTIFF
*.toc (CADRG, CIB)
  • STK uses Geospatial Data Abstraction Library (GDAL) to translate raster and geospatial data formats. GDAL supports certain well known coordinate systems natively (WGS84, WGS72, NAD83, NAD27) as well as any EPSG coordinate system (see www.epsg.org). For more details visit http://www.gdal.org/.
  • Converting an MrSID or JPEG 2000 image to .pdttx may take a significant amount of time and require a significant amount of temporary disk space (especially when re-projecting to latitude/longitude).
  • CADRG and CIB files can only be converted using the Multiple Image Converter or the Image Converter.
  • You can also convert single channel images (grayscale, for example) and images with more than 8 bits per pixel.
  • NITF images with C3 compression are not supported.
  • When loading an NITF image the following error may be encountered: ERROR 6: SetColorInterpretation() not supported for this dataset. This may indicate that the color table was not written properly, however, in most cases the color table will be correct and the message can be ignored.
  • STK only accepts the binary .ppm file format. If you try to load an ASCII .ppm you will receive an error message.
