Hi,

I'm trying to make a network analysis containing the time that is needed walking from one point to another. The thing is that i want to include slope, distance and walking speed in this analysis. Distance and walking speed shouldn't be too big of a problem, but I have no idea how to include the slope into the whole cost analysis.

Is there a way to combine the street features of the base map that I'm using with the slope "cost" before the network analysis or is there a way to do this while doing the analysis?

Thanks in advantage,

Markus

What you need is:

1. To get a Digital Elevation Model (DEM) if you need to get the slope values on your own.

2. Use the Slope tool in the Spatial Analyst extension - go through this tutorial which will give you a good start on calculating the slope - http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/Exercise_3_Finding_a_site_for_a_new_school/00nt00000008000000/

3. Assign the results of your analysis to each street segment (i.e., road link) and then use these values as a cost when running the network analysis.
