Abstract

This paper describes forestry research completed in central Alberta, Canada, using high-resolution STAR-2 synthetic aperture radar (SAR) imagery. Hard copy SAR imagery at 1:100 000 scale was used to map cutovers, and detailed area and boundary placement statistical comparisons were made between SAR- and photogrammetrically-derived maps. Results indicated a strong linear relationship (r = 0.98) between the SAR and photogrammetric maps, and that the standard error of the estimate was 4 ha for clearcuts that ranged in size from 0.5 ha to 100 ha. No significant difference existed between the SAR-derived and actual areas after a proportional linear regression model was employed. Cutover boundary mapping accuracy was also evaluated using a vector/perimeter displacement measurement approach, and results indicated that a displacement of −11 (signed vectors) or 29 m (absolute vectors) was attained, depending on the measurement approach taken.
