Using Airborne and Satellite Imagery to Distinguish and Map Black Mangrove Along the South Texas Gulf Coast

Color-infrared (CIR) aerial photography, CIR aerial digital imagery, and high resolution QuickBird multispectral satellite imagery were evaluated for distinguishing and mapping black mangrove mangrove [Avicennia germinans (L.) L.] populations along the lower Texas gulf coast. Accuracy assessments performed on classified maps of photographic and digital images of the same study site had both producer´s and user´s accuracies of 100% for black mangrove. In an accuracy assessment performed on a classified map of a digital image only of a second study site, black mangrove had a producer´s accuracy of 78.6% and a user´s accuracy of 100%. In a classification of the satellite image, black mangrove had a producer´s accuracy of 100% and a user´s accuracy of 85.7%.
