Importing SID Files

MrSID®, an acronym for Multiresolution Seamless Image Database, reduces the size of large, high resolution images while still maintaining the image’s quality and integrity. These files consist of an image file (*.SID) and a world file (*.SDW), which contains the geospatial information of the image. Both files must be in the same folder when opening the MrSID file.

To open, place, or import a SID file:

  1. Choose File | Open or Place, or GIS | Import.
  2. Navigate to the .SID file and click Open or Place.
  3. In the MrSID Import Options dialog box, select your settings.
  4. Click OK.
