Hello,
this issue is also seen with ArcGIS 10 SP 4. Specifically, REclassify, Reclass by Ascii file, Reclass by Table, and Lookup all fail with some data inputs (e.g., TIFF). If you close ArcGIS and restart 25% of the time one of the above tools will work, however no pattern was seen (e.g., Reclass by Ascii File in the 3D toolbox would work but the one in the Spatial Analysit toolbox would not).
Sounds like ESRI is not fully supporting TIFF image, one of the most popular formats for distributing satellite data.
I'm looking for a workaround on this.
Found that if I created a new file geodatabase and used that as the output location forthe Reclass by Table vs. outputing to a TIF it works.
