Hi dear Forum:

Does some method exist in order to automatically obtain the alltitude of all the points that form a path or route ?

I use GE Plus to extract the altimetry for some roads to bike over them, so I could know _in advance_ of the riding how much altitude i will have to climb (routes < 200 km)

what I currently do is: make a route in MapSource, export that route (as GPX) to Google Earth, and in GE _manually_ check each one of the points that form the route (could be as high as 250 points) in order to kmow its altitude

then I make a table (in an Office sheet) with the distance between points (given by MapSource) _and_ the altitude i have previously extracted from the 3D data of GE, and finally make a graphic of that table

as you could see, it is a rather lengthy process, so I would like to know if there is some way I could automatically extract the altitude data of each point in a path or route (because this is most time-consuming part)

do you know if such a method (using GE Plus) does indeed exist ?

i have attached a sample in what i am interested to have as a final result

thank you very much for your attention

greetings

I don't think GoogleEarth does that. But I think you can do that with MicroDem but you have to find the data for MicroDEM to use.
