A while ago I asked how I could interpolate some contour lines (bathy and isopachs) with ArcGIS 10.2 Spatial Analyst and I have been told to use the tool Topo to raster which did the job! I have just a concern about what I got.
basically I have a cable route and the bathy contour lines as well as the ispoachs lines; Once I use topo to raster it looks a bit odd that they cover a huge area outside of the cable corridor and I d not know if this is due to some parameter that I should have set or it is like it is.
For instance the screenshot below shows the cable route (in red) where they did the survey. Along that route I have either bathy contour data and isopach lines. Then using topo to raster I get the pic below and I am surprised that they cover a huge area outside the red line.
Do you have any suggestion?
many thanks and have a nice day,
