Hi all,

 

I want to apply this example of Calculating Solar Radiation to my work:

Explore Solar Radiation | ArcGIS for Local Government 

 

In the requirements of Calculate Solar Radiation Rasters task (see image 1), I have to "Enter the surface model you wish to include in the analysis. This can be a bare earth DTM or a DSM" in the Surface Model field. (see image 2).

From the internet, DEM is most of the time used as a generic term for DSMs and DTMs. This image on Wikipedia depicts the differences between DSMs and DTMs well:

 

 

Now, I ONLY have a (.TIF) image for my project. This image was taken by a satellite with very excellent resolution.

 

I suffered a lot of problem in running this example to my work as I don't have DSM or DTM for my work's area. I reach to this point after several investigation. 

 

The question:

 

Is there anyway to either convert my high resolution TIF image to DSM or DTM, or any alternative solution?

 

Note: There is not Lidar data or image for my work's area.
