How to Point Cluster when only having a layer?

Question

Hello everyone,

I am neither sure if what I am trying to do is super obvious or actually impossible. And since I am very desperate because I cant seem so be able to move it along. Here I go:

I have Layer (.lyr) file from Oak Ridge National Library Landscape (attached below) which contains data points and a corresponding scale for density. I want to cluster around the Nile River in Sudan in order to see how urbanization and overall population density changed from one specific year to the next.

However, I am unable to convert the layer file to a shape file as it gives me this window when I try to export it:

Do you guys have any idea how I could be able to cluster such a file as in this case?

Thank you in advance,

All the best,

Marius

Hi Marius,

It looks like you have a .lyr file of raster imagery.  You would need to get the raw imagery (i.e. TIF, IMG).  You could then convert this to a polygon or point feature class using the Raster to Polygon or Raster to Point tools.

Once you have a polygon/point feature class, you can execute the Optimized Hot Spot tool.

What would also help tremendously if you could tell me how I convert this file to a format for which I can use a Optimized Hot Spot Analysis.

Thank you!
