Evolving and Improving Implementation
• Initially implemented in raster. 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.
