Web Services

USGS GAP provides web service connections for its data sets, as follows:

Land Cover

  • National Vegetation Classification-Class Land Use — This web service provides a visualization of the U.S. National Vegetation Classification for the Class level. At the Class level vegetation types are distinguished based on dominant growth form (for example – Forest & Woodland).
  • National Vegetation Classification-Subclass Land Use — This web service provides a visualization of the U.S. National Vegetation Classification for the Subclass level. At the Subclass level vegetation types are based on dominant and diagnostic growth forms and global macroclimatic factors (for example – Temperate & Boreal Forest & Woodland).
  • National Vegetation Classification-Formation Land Use — This web service provides a visualization of the U.S. National Vegetation Classification for the Formation level. At the Formation level vegetation types are distinguished by dominant and diagnostic growth forms and global macroclimate factors as modified by altitude, seasonality of precipitation, substrates and hydrologic conditions (for example – Cool Temperate Forest & Woodland).
  • National Vegetation Classification-Division Land Use — This web service provides a visualization of the U.S. National Vegetation Classification for the Division level. At the Division level vegetation types are distinguished by combinations of growth forms, broad diagnostic plant species, and continental differences in mesoclimate, geology, substrates, hydrology, and disturbance regimes (for example – Vancouverian Cool Temperate Forest & Woodland).
  • National Vegetation Classification-Macro Group Land Use — This web service provides a visualization of the U.S. National Vegetation Classification for the Macrogroup level. At the Macrogroup level vegetation types are distinguished by diagnostic plant species and growth forms, and sub-continental to regional differences in mesoclimate, geology, substrates, hydrology and disturbance regimes (for example – Southern Vancouverian Dry Foothill Forest & Woodland).
  • National Vegetation Classification-Group Land Use — This web service provides a visualization of the U.S. National Vegetation Classification for the Group level. At the Group level vegetation types are distinguished by diagnostic species and growth forms and regional mesoclimate, geology, substrates, hydrology, and disturbance regimes (for example – Cascadian Oregon White Oak – Conifer Forest & Woodland).
  • National Vegetation Classification-Ecological Systems Land Use — This web service provides a visualization of types described by NatureServe’s Ecological Systems Classification (Comer et al. 2003) as well as land use classes described in the National Land Cover Dataset 2011 (Homer et al. 2015).
