Intersect Subsurface Points with Surface Raster
I have some elevation points along a polyline (subsurface) and a raster based on surface elevation points. If I have a given angle of slope from the subsurface points extending towards the surface raster, is there a way to determine where it will intersect with the surface raster? I have to do this for about 400 points, but the angle should remain constant. Thanks!
Mapping Center Answer:
This can be done via script on a TIN using ITinSurface3.QueryLocate. You need azimuth and dip angles along with each point to define rays which are intersected against the TIN.
Support has been added in 10.1 to do the same thing with rasters. Until then, you need to convert the raster to TIN using the geoprocessing tool RasterToTIN.
Also, in 10.1, we'll be adding the Intersect 3D Line with Surface geoprocessing tool which is a little different than what you asked for but may be useful in related applications.
