Can you add weights to a line density raster file?

[ArthurGuerrero]

I have a student who wants to know how to assign a weight when creating a line density map, I believe there is a way but don't know which tool is capable of doing it.

Her example; I would want to know if the majority of trajectories are coming from the Pacific Ocean, but the majority of actual rainfall is coming from the Gulf of Mexico. 

I would appreciate any insights and thank you very much,

Hi @ArthurGuerrero ,

The following links are about how line density works:

https://pro.arcgis.com/en/pro-app/latest/tool-reference/spatial-analyst/how-line-density-works.htm

https://desktop.arcgis.com/en/arcmap/10.3/tools/spatial-analyst-toolbox/line-density.htm

you can find the Line Density tool in ArcGIS Pro / ArcMap from Spatial Analyst Tools > Density > Line Density

I hope that helps.
