https://community.esri.com/t5/arcgis-pro-questions/optimizing-area-solar-radiation-tool-performance/m-p/1475310#M83470 <P>Hello,</P><P>I am using the Area Solar Radiation tool in ArcGIS Pro. My DSM layer files are large, and reducing their resolution introduces significant errors, so I cannot lower the resolution. To speed up the simulation, I have split the raster DSM layer file into several smaller sections, but the simulation still takes a long time.</P><P>Is there any other solution to speed up the simulations? I have also tried increasing the processing parallel factor, but it did not work; I believe ArcGIS Pro does not support parallel processing for this tool. Any recommendations?</P><P>Thank you.</P> Mon, 20 May 2024 11:25:00 GMT AlexKazemi 2024-05-20T11:25:00Z https://community.esri.com/t5/arcgis-pro-questions/optimizing-area-solar-radiation-tool-performance/m-p/1475310#M83470 <P>Hello,</P><P>I am using the Area Solar Radiation tool in ArcGIS Pro.
