I am looking at a project which involves a hazard assessment of several
hundred kilometres of pipeline route. I need to find where the
pipeline crosses valleys and classify the steepness of the approach
slopes to the stream.
I have vector coverage of the stream courses and raster DEM topographic
How can I extract the locations where the pipeline intersects the
What options are available to classify the steepness of the slope on
the pipeline route and perhaps display with a vector line with a width
proportional to slope or colour proportional to the slope.
Thanks in advance for any help.
