I'm making a final map of a wild fire. I have several polygons, which show its progression. The only problem being, the final perimeter is smaller (more accurate) than some of the early ones. So it confuses the intent.
The audience is for the fire management people, the purpose to communicate as much info as possible. How would some of you cartographers represent this data?
I think what I might do is drop some of the less significantly changed perimeters and then add a crosshatch or transparency fill to the final perimeter, which I would place under the earlier perimeters.
Attached is an outline of what I'm dealing with, the thick BLUE being the final and most important piece of data. I will probably use either an illuminated relief/generalized land cover or color aerial photo as a base layer.
I'm not sure how I should portray this, or if it is even possible to effectively do so. Any/all advice appreciated
