I was given a file and asked to get an area and perimeter by utilizing the field calculator with python.
To get the area I did the following:
Area = !shape.area!
To get that perimeter did something very similar but got some odd numbers:
Perimeter = !shape.length!
Ultimately I am trying to calculate the PolsbyPop and since that's on a scale from 0 to 1 I knew that these numbers wouldn't work.
Using the calculate geometry function with Perimeter length (geodesic) gave the following:
Which in turn gives PolsbyPop values in the range I was expecting. What is the reason for the difference on the perimeter values and how I can I fix it? I have a feeling it has something to do with units but i'm not sure how to change it.
