Errors when displaying ECW files

by Technical Evangelist on ‎07-19-2016 07:52 AM (517 Views)

Symptoms

Errors occur when displaying ECW files.

Diagnosis

One possible reason for observing errors could come from using an ECW format version that is not supported for the version of ERDAS software (ER Viewer, ERDAS IMAGINE, ER Mapper) that is being used to read the ECW file. ERDAS software version 11.x and earlier did not support the ECW version3 format which was introduced in later versions of ERDAS software (13.0 and higher). The errors shown below are witnessed when attempting to display an ECW file. Other ERDAS software programs may show different errors when reading the ECW version3 file.

Solution

Solution alternatives:

  1. Install a later version of ERDAS software (version 13.0 or higher).
  2. Change the format selection of the ERDAS software to write ECW version2 format which will allow users of older versions to read the ECW version2 format.
