Building Raster from Coordinate Points (csv)

[BarrettLewis1]

Hello, the goal of what I am trying to accomplish is to subtract the elevation values of one raster from another. I have a .tif file of one raster, and for the other, I have a .csv with coordinates and elevation values, from which I made a point feature. I've tried two things to turn the points into a raster or other:

1)Point to Raster

Point to Raster comes out the best, but some points out spread out too thin. Is there a way I can stretch values?

Interpolation didn't seem to be at all what I needed but I saw some suggesting it in previous threads. Any thoughts?

you could use

Extract Multi Values to Points (Spatial Analyst)—ArcGIS Pro | Documentation

and do the subtraction in the point featureclass rather than working with subtracting the rasters

You could execute Topo to Raster (Spatial Analyst).

Input Feature Data Type: Point Elevation

Output Cell Size: Same as the other raster dataset

Primary Type of Input Data: Spot

In tool environment, define Snap Raster (Environment setting) to the other Raster Dataset.

Once the output Raster is created, you could execute Minus (Spatial Analyst) or use Raster Calculator.
