Kernel Density is not showing in full map

tomGIS — Wed, 02 Jun 2021 19:45:28 GMT

Dear Altruist,

I am new in ArcGIS. I am trying to do Kernel Density analysis in ArcGIS. But, KDE coloring chart is not showing full map. It only shows where values are available. I want to show the color in full map.

Kindly help me.

Thanks in advance!

I don't entirely understand your issue from your description but at a guess - Possibly adjust your symbology classes or set a min-max stretched symbology or rerun the analysis with a larger search radius.

Thanks for your reply.

It is the sample of this. I want to spread the color in full map.

I can only guess that the area pictured is the minimum bounding rectangle(extent) of your input features.

Perhaps alter the Extent geoprocessing environment setting to 'same as display' or that of an appropriate layer.

I have selected "Same as Display", but it is not working. 😞

Did anything change as a result? Are you overwriting the layer or creating a new output? (ensure the output is added to the map)

Are you able to provide clearer screenshots of the input data you're creating the kernel density from?

I'm also going to point out that it seems you're running density analysis whilst in WGS84 coordinate system, you should be using a planar coordinate system, as the output will be pretty meaningless otherwise.
