I am new to ArcGIS Pro and geospatial data in general. I have downloaded settlement extents data from https://grid3.org/. I had naively thought the data would display the population in a heatmap like manner, such as from green(lowest population) to red(highest population). But this is what I have Gray Settlement Extent

This is how the attribute table looks like Attribute Table

My two questions are:

  1. What would the process in ArcGIS Pro to create a population heatmap?

  2. How to avoid the settlement extents covering the countries boundaries ?

The reason there is no heat-map is because with a GIS Software (like ArcGIS Pro) it leaves it up to you to decide on exactly how you want to the data to look.

  1. To show the country layer above your settlement data, drag the layer on the contents pane so it appears right at the top.

  2. To display the data as a heat-map you need to change the symbology and pick the attribute (maybe population, maybe pop_un_adj -it's up to you) you want displayed in different colours.

I suggest that you play around with the layer order (contents pane) and symbology and search the online documentation (or just the internet in general) for more information on exactly what you want to do. Also search using "ArcGIS Pro" rather than Arc or ArcGIS as the older version of the software ArcGIS Desktop is still widely used.

The latest documentation for heat-maps is here: https://pro.arcgis.com/en/pro-app/latest/help/mapping/layer-properties/heat-map.htm
