Projects > Southern Ontario Deforestation Mapping Accuracy Assessment

Caslys conducted an accuracy assessment of deforestation mapping for a region in southern Ontario. The mapping in this area evaluates the rate of change between two time periods – 1990 and 2000. The accuracy assessment involved mapping sample plots covering test locations throughout southern Ontario. Project deliverables included: georeferenced satellite and air photo imagery for all time periods; an ArcGIS geodatabase containing spatial information and related attributes depicting scan points (truth events); the locations of deforestation events in the study area based on the original candidate events updated during the assessment with information from air photos and IRS imagery; metadata documenting the data and the interpretation tasks; and a report documenting the methods used to generate all data products.
