    Can't view ESRI Grid Files

    sokorny
      Hi,

      Well been using ArcMap 9.3.1 for over a year now, primarily to analyse and model ESRI Grid files (in a binary format). I also have 3D Analyst and Spatial Analyst.

      Over the weekend our server was updated and now I can not view any of these files. It gives me the error message "Unknown Spatial Reference" when I try to bring them into ArcMap, and then won't display them at all. In ArcCatalog it simply won't display the image.

      They all have projection files, which are correct.

      The files are the same as they were on Friday, but for some reason I can't view them in ArcMap or ArcCatalog anymore.

      I have run the "REPAIR" feature on my installation DVD, but with no luck.

      Am I missing something? What are my options?

      Thanks, Pete
