Extract solar radiation on rooftops using building footprint as mask

Alfedwards — Tue, 30 Apr 2019 00:41:43 GMT

Hi i am using Arcgis Pro. I am trying to get the total solar radiation on rooftops in a city.

I used the image classification wizard to classify satellite imagery to get get a building footprint.I Have also a DSM which i ran through the area solar radiation tool

It would be great if someone could help me with the following:

1) how to use the building footprint as a mask, so i can just get the solar radiation on the roofs( i tried using extract by mask but not able to see the solar radiation for the buildings)

2) calculate the total area of the roof.

3)how to get solar radiation on the north facing roofs only.

I think the answer you're looking for can be found in our Calculate Solar Radiation solution, which is an ArcGIS Pro project package (.ppkx) that contains workflows to calculate, visualize, summarize, and publish solar radiation results for selected roofs. The package contains 4 different tasks that will walk you through each workflow, including Summarize Solar Radiation for selected Roof Areas, which could be the tool you need.

The sample data in the package is for Naperville, but you will substitute it with your own. If you need building footprints (rooftops), you could use the new nationwide Building Footprints layer by Microsoft. Here is a short, 6-minute video to see the solution in action.

To get this package, you'll need to install the free ArcGIS Pro Solutions Deployment Add-in.
