Hello,
I am adding county data as a ShapeFileFeatureLayer. Then I am adding InMemoryFeatureLayer of ski resorts. To find the intersection, I am assuming that I would have to loop through the county layer and within that loop, loop through the InMemoryFeatureLayer layer.
My question is:
1. How do you loop through the ShapeFileFeatureLayer layer?
2. How do you loop through the InMemoryFeatureLayer layer?
3. How do you determine if they intersect?
4. How do you get the feature information of the two that intersected? For example (County A, Park City)
Thanks, Steven
