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 pu 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 Lenght of each segment in metres (with Calculate geometry there is not option to obtain Z values) . I tryed 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.
