Richard, Thank you for the tip! The Linear Referencing solution worked perfectly 😄 For anyone's future reference, here is a visual explanation of the final solution: I created a line from the points (which included elevations) that I already had, resulting in a PolylineZ. Then, using that PolylineZ, used the "Create Routes" tool and "Length" as the Measure Source to create a PolylineZM: Using this layer, I ran the "Locate Features Along Routes" on my points of interest, which gave me a table of the resultant points and the route they were found along: I then right-clicked the table and used "Display Route Events" to display the resultant table of points along the Route that I created earlier: Using this layer, I added a new field to the attribute table for the interpolated elevation values. Finally, I used "Calculate Geometry" on this field to interpolate the Z Coordinate of each point in this layer: This method seems to work just perfect for what I was doing, but if anyone else has anyone else has any other suggestions, please add to this thread. Thanks again, Richard! 🙂
