topic What determines square/cell size in optimised hotspot analyses? in ArcGIS Spatial Analyst Questions https://community.esri.com/t5/arcgis-spatial-analyst-questions/what-determines-square-cell-size-in-optimised/m-p/373686#M5236 <HTML><HEAD></HEAD><BODY><P>Hi there! <BR />I'm fairly new to using GIS and am using ArcGIS 10.2. I have created a few optimised hotspot analysis for different field of the same dataset. They're all creating great maps, but the output cell/square sizes vary greatly. I was wondering if anyone could tell me what it is that determines this cell size and if it is possible to standardise it?<BR />Thanks!</P></BODY></HTML> Mon, 16 Feb 2015 05:56:22 GMT LaraPogson-Manning 2015-02-16T05:56:22Z What determines square/cell size in optimised hotspot analyses? https://community.esri.com/t5/arcgis-spatial-analyst-questions/what-determines-square-cell-size-in-optimised/m-p/373686#M5236 <HTML><HEAD></HEAD><BODY><P>Hi there! <BR />I'm fairly new to using GIS and am using ArcGIS 10.2.
