I am attempting to rasterize a point layer using the Feature to Raster conversion tool. Each attempt, I receive the following error codes:

  • ERROR 010429: Error in GRID IO: CellLyrCreateInternal: Grid: n:... alrady exists
  • ERROR 010067: Error in executing grid expression

This layer does not already exist. Can attribute field type (double vs float vs integer) produce this problem? Each time I try to change field types, or create a new attribute column of a different field type in either ArcMap or ArcCatalog, the column will revert to double, no matter which type I set it as. Any thoughts?

    Try rebooting pc? – Hornbydd Feb 23 '15 at 19:04

    Perhaps it's referring to an intermediate "temporary" grid created in memory for processing, rather than the output? Rebooting is a good idea, but you can also change the scratch workspace (or try logging in as a different user). Data type should not matter, as the output raster will simply match the input type. You cannot change an attribute data type once it's been created. It is a bit odd you can't create a new attribute of a different data type and that it reverts to double. – Chris W Feb 23 '15 at 22:13
  • Thanks for weighing in. Reducing the precision of the attribute field turned out to be the fix. In addition, I discovered that if I selected an attribute field precision of greater than 7 for a float field type, the field type would revert to double. – bubbalouie Feb 24 '15 at 19:30
  • That's because floats can't have a precision greater than six. See resources.arcgis.com/en/help/main/10.1/index.html#//… – Chris W Feb 25 '15 at 3:52
