CATALYST has a full set of object-based image analysis (OBIA) tools that can be used to quickly and accurately extract impermeable land area on a per parcel basis. Imagery is segmented based on the shape and spectral properties of features, and training sites representing impermeable and permeable classes are collected.
Results:
It was found that using CATALYST’s OBIA tools reduced processing time by 93% and generated results with 88% accuracy compared to manual digitization.
Workflow
OBIA was performed on 30 residential parcels in the Eatonville neighborhood of Toronto using Geomatica Object Analyst. Generating a vector layer of impermeable area took 20 minutes total.
