My situation:
I am relatively new to GIS so forgive me if this is a stupid question. I am working on a project at a park that I am interning at where the goal is to create a single feature with roads and trails together with some way to show the total distance of selected roads and trails.
Currently I have merged the roads and trails features, so I have a single feature with both which contains separate fields with their respective distances. In its current form I could simply add distances manually from selected trail and road intersections, but I was interested in automating a process to show this. I was thinking some kind of model (made in ArcGIS model builder) that when run would return an output table of the summed distance of currently selected features.
Question:
1) How can I tell ArcGIS model builder to perform calculations on just selected features?
2) Is there a better way to accomplish the above mentioned task?
Thank you for any input.
