Generic Featured Image

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.
