Multiple Line Datasets

[JimCrane]

I have two line feature classes: One shows new proposed fireline locations and the other, locations of roads/trails that may be used for firelines. These two line sets are concurrent in multiple locations. How do I Spatial Join, Intersect, etc. to produce one line set that shows the new construction and the existing (roads/trails) lines.?

Hi Jim,

One workflow is make a third feature to represent the intersection.

- layer 1 is Fierline

- layer 2 is Roads

- Use Intersect, 

- Result is Layer 3 Fireline - Roads

Or, A second workflow would be to Attribute one feature class with fact it is also the other feature class.

-Run Add field on the Fireline layer adding "IsRoad"

-Use Split by Line at vertices on the Fireline

-Select by location the fireline when it intersects the road (Tool or Workflow)

-Calculate field "IsRoad" = Yes  (This only attributes the selected records)

-Dissolve the Fireline on name and IsRoad fields

- Result is a field in Fireline identifying it is a road.

Hopefully one of these works, If not can you help me understand your data better? What's important about the intersection or final output. 

Cheers,
