Automating City Parcel Updates


Eden Prairie uses Hennepin County's parcel data to ensure data quality between the city and county.  Hennepin County sends updated parcel shapefiles to Eden Prairie, the downfall is that the data is for the entire county, and in Eden Prairie's case any data outside of the city is irrelevant.

The code create from model builder automates the process of updating the city parcels, deleting the unnecessary data, adds relevant fields to comply with Eden Prairie's data and correctly stores to files. The process of updating this information is rather tedious but is a reoccurring update to the database every couple months.

The model builder and a few custom codes completely automated the process to save time and energy on mundane tasks.
