I’m working on a project where I need to estimate about 1400 pipe inverts using the adjoining pipes and manholes. The problem is a lot of the adjoining pipes are missing elevation data as well, so there are long segments of pipes missing data. I was wondering if anyone knew of an automated way to estimate the invert elevations. I haven’t had to estimate the inverts for this many pipes before, and I realize doing so one by one would take a lot of time. I have extracted upstream and downstream rim elevations using the USGS DEM, and using minimum slope would work for this analysis as well. Please let me know if you have any suggestions.
I'm using ArcGIS Advanced with spatial and 3d analysis. My dataset isn't in a geometric network.
