A vegetation database of the riparian vegetation located within the Colorado River ecosystem was constructed using four-band image mosaics acquired in May 2002. A digital line scanner was flown by ISTAR Americas using a Leica ADS-40 digital camera over the Colorado River corridor in Arizona to acquire a digital surface model (DSM) and four-band image mosaics (blue, green, red and near-infrared) for vegetation mapping. The vegetation base map was constructed through a combination of ground surveys to identify vegetation classes and image processing and automated supervised classification procedures. Analysis of the imagery and subsequent supervised classification involved multiple steps to evaluate band quality,...
Multi-season satellite imagery (Landsat ETM+) from 1999-2001 were used in conjunction with digital elevation model (DEM) derived datasets (e.g. elevation, landform, aspect, etc.) to model natural and semi-natural vegetation. The minimum mapping unit for this dataset is approximately 1 hectare. Landcover classes are drawn from NatureServe's Ecological System concept. For the majority of classes, a decision tree classifier was used to discriminate landcover types, while a minority of classes (e.g. urban classes, burn scars, etc.) were mapped using other techniques..

The U.S. Geological Survey (USGS) Upper Midwest Environmental Sciences Center (UMESC) has produced the Vegetation Spatial Database Coverage (vegetation map) for the Acadia National Park Vegetation Mapping Project, USGS-NPS Vegetation Mapping Program (VMP). The vegetation map is of Acadia National Park (NP) and extended environs, providing 99,693 hectares (246,347 acres) of map data. Of this coverage, 52,872 hectares (130,650 acres) is non-vegetated ocean, bay, and estuary (53% of coverage). Acadia NP comprises 19,276 hectares (47,633 acres) of the total data coverage area (19%, 40% not counting ocean and estuary data). Over 7,120 polygons make up the coverage, each with map class description and, for vegetation...
