Limiting contour lines

Detective_M — Tue, 02 Sep 2025 22:04:26 GMT

Hello, I'm using ArcGIS Pro and I have some contour lines, and a series of points. I want to see which points fall within particular elevations. I'm using DTM data from digimap. Is there:

a) a way to intersect points and contours so that the points only show for particular elevations (in my case, I want to see what's between 0-15m OD)

b) a way to not show contour lines above a certain number? I have a minimum height of 0 and a maximum height of 255 for my raster-I only need contour lines to show up to 20m

I'm not sure about some things here. You have points and a DTM. I would attribute the Raster DTM values (the elevation) to your feature points using Extract Values to Points (Spatial Analyst)—ArcGIS Pro | Documentation
How To: Extract Raster Values at Point Locations in ArcGIS Pro
then Filter features with definition queries—ArcGIS Pro | Documentation use a Definition Query on your attributed point layer (WHERE RASTERVALU is Greater than 0 and RASTERVALU is less than or equal to 15)

Your contours will have a height attribute to use the same Definition Query method to limit their display by elevation - Unless your contours are part of the raster basemap. If that's the case, there's not much you can do other than source some alternate contour data, or produce contours from your DTM. How To: Create Contour Lines in ArcGIS Pro
and Youtube / Google.

Contour (Spatial Analyst)—ArcGIS Pro | Documentation

with contour polygon option, then use whatever overlay operation you are comfortable with (spatial join, select by location, intersect etc
