I have used Interpolate shape tool in 3D Analyst (ArcGIS 9.2) in order to obtain Z-values of each segment along the stream lines.
As input features I use Riverstream.shp file and as raster surface the DEM. With right click on interpolated riverstream.shp after opening the attribute table, I created new column for X and Y coordinates. With right click on each column(for X & Y) using Calculate geometry I obtained X,Y values.
I need also to obtain elevation values (Z-values ) for stream segment as well as length of each segment in meters (with Calculate geometry there is not option to obtain Z values). I tried with Field calculator but without success.
Can anybody help me : How can I assign Z-values of stream segments. For your help thank you in advance. Subija.
