How do you create a transect?
It is possible to create transects using a simple line feature class (without M-values and the route identifier field).
- Drag the line feature class from the Catalog pane onto the map.
- Create a main line feature by tracing a portion of an existing feature, which in this example is the Middle Fork Kaweah River.
