Difficulties Creating Space Time Cube

[KLMapes]

I am currently working in ArcGIS Pro 2.7.2 with the Create Space Time Cube by Aggregating Points tool. I have a point layer of fire occurrences that I am trying to aggregate to county polygons. I keep running into an issue when trying to define my Defined Polygon Locations input where the tool is not allowing me to select a Location ID field. It is giving me an error 000308 for Invalid Field Type. I cannot find any documentation on what field types are supported so I can correct this error. I have attached a screen shot of the tool inputs.

Could you keep the parameter blank?

No it is mandatory

Hi @KLMapes ,

The Location ID must be a numeric field. I would recommend using the Calculate Field tool to create a new Short or Long field with the same values from your GNIS_ID field.

Hi @LynneBuie I have a similar problem in that my location IDs are alphanumeric (eg. BB01) is there an easy fix for this or do I need to rename all the location IDs to number only identifiers?
