Time consuming and prone to error introduction. Moved to vector, working with attributed polygons. Initial models used Excel. Moved to Access to reduce error introduction through transcription. Initial vector models used Model Builder. Moved to python to make implementation more transparent and reproducible. Improvements result in ability to rapidly iterate changes in model to visualization in map. Modeling issues can be quickly visualized and corrected.
