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,...
This data layer identifies the full mapping boundary for a vegetation map of the Hakalau Forest National Wildlife Refuge Hakalau Forest Unit and adjacent lands, island of Hawaii.
This data release includes a file geodatabase with land cover maps for a 313-kilometer segment along the mainstem Klamath River corridor downstream from Iron Gate Dam, CA. The maps were derived from high-resolution (15cm) imagery and topobathymetric elevation data, collected by NV5 Geospatial (formerly QSI, Inc) and published on Open Topography (https://doi.org/10.5069/G9DN436N). Acquisition dates spanned 06/01/2018 to 06/14/2018. The area of interest was discretized into three zones and land cover maps were generated using geoprocessing tools, implemented in ArcMap 10.8.1, and image classification tools, implemented in Ecognition 10.2. The maps include six land cover classes: 1) trees, 2) shrubs, 3) grass, 4) bare...

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..

This data layer identifies location and boundaries for 100 randomly located plots used to assess the accuracy of the Hakalau Forest Unit (HFU) map area for the vegetation map of the Hakalau Forest National Wildlife Refuge Hakalau Forest Unit and adjacent lands.
Complete existing vegetation coverage of North Slope study area provided by combination of NSSI Landcover Map and Vegetation Map of Northern, Western, and Interior Alaska. Terrestrial sub-regions provide potential for both North to South and East to West comparison of spatial patterns within the North Slope study area. Map of Terrestrial Coarse-Filter CE distributions within the North Slope study area. Temperature projections for July. Projected mean January temperatures. Current, near-term future, and long-term future length of growing season in the North Slope study area. These data are provided by Bureau of Land Management (BLM) "as is" and may contain errors or omissions. The User assumes the entire risk associated...
