Good morning, All
I have an assignment. We will classify watersheds based on the area to perimeter ratio in the huc4.shp shapefile.
In the Contents, right-click the huc4 layer and click Attribute Table. Review the fields of watersheds. Notice that there is a field called SHAPE_Area and a field called SHAPE_Leng.
Task: Write a script in Python that will determine the Class of each polygon by calculating the area to length ratio and grouping into a Class accordingly to the table below. In ArcMap, create a map assigning symbology to the Class as follows.
Area/length Ratio | Class | Symbology |
Ratio > 40,000 | Low | Green |
20,000 < Ratio <= 40,000 | Medium | Brown |
15,000 < Ratio <= to 20,000 | High | Orange |
Ratio <= 15,000 | Very High | Red |
********************************
I wrote a python script. However, it occurs an error ' Stop Iteration'. How to fix it?
Appreciate the solutions.
