Forest species mapping
Résumé
Remote sensing has become increasingly important in vegetation mapping. Early applications pertained to aerial photography, but more recently satellite imagery with a huge range of spatial and temporal resolutions is in use that increases the applicability's from entire ecosystems to specific vegetation types. Some mapping projects apply remote sensing to segment thelandscape into homogenous polygons to aid field surveyors, while others produce maps directly from imagery by combining imagery with other spatial data sets. The latter approach is gaining momentum in the light of major improvements in the technology. Using a mixture of remote sensing and field methods seems to deliver the best results.
