Description
Analyses requiring square or hexagon bins or using Join Features with a spatial relationship of near, require a projected coordinate system to correctly compute results.
Solution
If your input is in a geographic coordinate system, set the output coordinate system to a projected coordinate system using the Environment settings. Inputs with an output coordinate system will first be projected to the input coordinate system and then analyzed. Results will be in the coordinate system of analysis for the relational data store and in WGS84 for the spatiotemporal data store.
