split a street but height

[huntergropyhuntergropy]

hello:

I have a shape with many streets and I split up the streets (every 120 meters height difference) and in part that "divide" should know that is kilometers.


thanks

ps: sorry for my English, I do not write very well English and this is thanks to google translator

Hi Huntergropy-

I'm not sure if I understand what your question is.  Do you want to divide the streets by length (not height)?

I don't think there is a tool specifically for splitting a line by elevation, but if you have elevation contour lines then you can export the contour lines out to a new line layer at intervals of 120 meters and use the intersections between these contours and your streets layer to split your streets.

If don't have contour lines but you have a TIN ("Trianglular Irregular Network") or DEM ("Digital Elevation Model")surface data set and a 3D Analyst license you can use the Contours tool (http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//00q900000021000000) to create contours at 120 meter intervals.  Then where the contour lines intersect the street lines you could break/split the street lines.

There are two methods to do this:

1) You can use the "Splitting lines at intersections with Planarize Lines" (http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//001t0000008t000000.htm)

2) You could do this by creating points at the intersections then split the street line by those new points.  To create the points you would merge both the streets and elevation contours lies into one feature class using the Merge tool (http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//001700000055000000). 

With this new merged feature class you can create a Geometric Network (http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//002r00000001000000)
(While you wouldn't need the network that this process creates, a byproduct of this process is that it automatically creates points at intersections).   Then you can go back to your original streets feature class and use these new intersection points with the Split Line at Point tool: http://help.arcgis.com/en/arcgisdesk...0000003w000000


I hope that this is helpful!
