FAQ: Why won't some of my TIFF raster files display in ArcMap?

Question

Why won't some of my TIFF raster files display in ArcMap?

Answer

The TIFF specification is quite broad; thus, many variations of TIFF files exist. This can cause a number of difficulties with reading TIFFs between different applications. The two most common issues for TIFFs in ArcGIS are:

· The TIFF contains LZW compression, and you currently don’t have a license to use this type of compression. For more information, search for “LZW license” in the ArcMap on-line help.
Reading a raster dataset with an LZW license is no longer an issue in some countries - due to the end of the patent.

· The TIFF contains JPEG compression, which is not supported by ArcGIS.
From ArcGIS 8.2 and on, we are now able to support TIFFs with JPEG compression.
