Error message

Unable to decompress pyramid data Fusion Fatal: PrepLoop: Unable to read tile (lrc)

Description

This error occurs when you try to build an imagery project with a corrupt imagery resouce.

Resolution

  • If the imagery project must be finished as soon as possible and the failed imagery resource can be omitted:

    Drop the failed imagery resource from the project. A new version of the imagery project will be built that does not include the corrupt imagery resource.

  • If the imagery project must be finished as soon as possible, the failed imagery resource must be included, and the source is based on prebuilt imagery .kip/.kmp folders from another machine:

    Verify that all .pyr files in both the .kip and .kmp folders are their true size between both systems, then replace any .pyr files that have differences between file sizes or checksums. To check for differences, calculate md5 checksums for each pyramid file in the source folders and the target folders. You can restart the failed imagery project blend, or blends, afterward.

  • If the imagery project does not have an immediate deadline, the failed imagery resource must be included, and the imagery resource was imported from raw source files (such as JPEG2000 or GeoTIFF) that have good integrity and are not corrupt:

    Re-import the source imagery as a new version of the imagery resource. Build a new version of the imagery project to blend the new version of the imagery resource.
