I have a polygon feature class representing our county by Land Type, and I'd like to add a field showing the percent of the total area by each type.
I did this before by summarizing to get the total area and manually entering that value into an Arcade expression to calculate the percentage for each feature.
I'm trying to create a model in Model Builder so that I can automate the process in the future, but I'm not sure how to calculate the total area and feed that variable into the Calculate Field tool to get the percentage of each feature. Does anyone have a suggestion on how to do this?
