It’s What’s on the Outside That Counts: Picturing Quality and Condition

Tuesday February 23, 2027 10:30am - 12:00pm PST

Daisy, 2nd Floor

This session follows one thread: parcel imagery, from the ground up. We start with the practical side; camera setup, metadata, and how to build and manage Oriented Imagery Datasets in ArcGIS Pro, so you've got usable photos to work with.

Then we get to the interesting part: what to do with them. Quality and condition are two of the trickiest fields in CAMA data. Quality is locked in at construction; condition drifts with time and wear, and visually, the two blur together. We trained a multiclass image classifier on existing CAMA grades to see if it could tell them apart from exterior photos alone. The real test: does it hold up on properties it's never seen before?
