Optimized hotspot analysis (ArcGIS Desktop 10.5.1) tool failing to excecutet gives me the following

FrancoisBekker — Thu, 13 Jul 2017 11:23:26 GMT

Hi Guys,

I have 399 incidence points on which I would like to run Optimised Hotspot Analysis with the aggregate into fishnet option selected. The goal is to determine the polygon size (fishnet block size). When running the tool in ArcGIS 10.5.1 it gives me the following output:

Executing: OptimizedHotSpotAnalysis TRAP_LOCATIONS_EGVV_UTM_WG_84 "E:\Academic\ArcGIS_Files\EGVVProject2017CorrectProjection\Analysis Locations etc\Trap_Icidence_Hotspots.shp" # COUNT_INCIDENTS_WITHIN_FISHNET_POLYGONS # # # # #

************************** Initial Data Assessment ***************************

These are the points that I want to use for the analysis.

Can anyone please help me?

Kind Regards

Hello!

I am moving this to Spatial Stats and will look into it in the morning. Can you tell me if you are using a language pack?

I have looked at it, and this seems to be the root issue.

Did you try running it from a shorter pathway, let's say: c/temp/yourfolder, any other errors?

I am getting the same error. Any approaches to solve this?

I seem to be running into the same issue. Still no clue as to what is causing this?

Posting my output below. Running 10.5.1, not using any language pack so that is not the issue here.

Hello Jimmy, I had the programmer take a look at this issue and it seems that the issue lies in the xyDomain variable ... there seems to be a Unicode character inside it. This variable needs to be able to be transformed from a string to a float. You could try to change only the bolded line below in the code for the tool and see if that fixes it. It would also help if you provided the data that you are using, a portion of the data with the spatial reference that is causing the traceback or at least letting us know the spatial reference you are using so we can look into it and try to fix it for the future. Let us know if this works for you! Thank you!
