Creating Heatmap from attribute value of point features in ArcGIS for Desktop?

HenriLim — Mon, 30 Nov 2015 06:10:42 GMT

I've run through tutorial from ArcGIS on how to create a heat map using Spatial Analysis.

Based on the example, point features are scattered around the map and we need do the following to generate heat map.

Run Project Data -> Integrate Data -> Collect Events -> Run "Hotspot Analysis" -> Run "Spatial Analysis"

Is it possible to generate a heat map if I don't have point features that are scattered around the map but instead I have point features that have an attribute value that represent "Number of point" around this point features?

For example: I have 5 locations.

In the first scenario, I will have

5 points feature around area #1
20 points feature around area #2
40 points feature around area #3
30 points feature around area #4
10 points feature around area #5

While for second scenario, I will have

Point feature 1, attribute value: 5
Point feature 2, attribute value: 20
Point feature 3, attribute value: 40
Point feature 4, attribute value: 30
Point feature 5, attribute value: 10

I managed to achieve the heat map I'm looking for using Kernel Density (Spatial Analysis) and use the respective attribute as a value for "Population Field".

Henri, you should mark your question as "assumed answered" since you were able to answer your own question. That will allow this thread to be closed. thanks.

You should also move this to a more appropriate space, such as GIS or Spatial Analyst, and use tags to help those searching on this subject in the future.
