Occurrence:
I receive the following error when attempting to run Multi-Trend gridding.
"Array dimensions exceed the allowed range."
Resolution:
Their are two suggested workarounds to this error:
1. Using a larger Starting and Final cell size.
- The default Starting cell size will normally be ¼ to ½ of the line separation or the nominal data sample interval.
- If your unsure what cell size to enter, use the Calculator button beside the Starting Cell Size parameter to see the recommended cell sizes and work down from there.
2. Divide your input database (*.gdb) into smaller areas.
- If reducing the cell size isn't an option, you will need to subset your gdb into smaller areas
- There are a number of methods to subset a GDB by going to Database Tools > Window a Data
Root Cause
The error message is related to hitting the processing limit of the function. The function was compiled in C#, which has a maximum memory usage limit of 2 GB. That said, the error could be triggered when using a smaller cell size or if your extents are two large for the cell size your attempting to grid.
