Overview
- I want to generate elevation profiles for bike routes / bike paths.
- I also want to generate those nifty chevrons that indicate grades on routes.
Generating a profile
ArcMap script: This this Python script would be a starting point to generate the graphics.
Of course there is a way to make a profile in 3D analyst.
Setting up the map
I need an elevation layer. Marin has 1/2 meter data but has removed it from their website. I looked at NED data from The National Map, 1/9 arc second is not good enough for this.
I am trying to get the data from MarinMap but it's not online, have contacted the GIS people there to find out why it's missing.
