Building Raster from Coordinate Points (csv)

Question

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 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.

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
