USGS Land Use and Land Cover (LULC) Data
Entry ID:
1_250_LULC
Summary
Abstract:
The National Mapping Program, a component of the U. S. Geological Survey (USGS), produces and distributes land use and land cover maps and digitized data for the conterminous U.S. and Hawaii. Land use refers to the human activities that are directly related to the land. The interpretations are based on a land use and land cover system developed for use with remotely sensed data. The ...

Quality
Initial source preparation involves the transfer of field survey information, photo classification detail, and associated line work to a base map for digitization. This may be done through stereo compilation or monoscopic transfer techniques. Adjacent maps are also checked to ensure continuity. The maps are digitized and the appropriate classification codes are assigned for processing through the Geographic Information Retrieval and Analysis System and checked for accuracy. All LULC data conform to the Universal Transverse Mercator projection.

There is no guarantee of warranty concerning the accuracy of these data. Users should be aware that temporal changes may have occurred since the data was collected and that some parts of these data may no longer represent actual surface conditions. Users should not use these data for critical applications without a full awareness of their limitations. Acknowledgement of the originating agencies would be appreciated in products derived from these data. Any user who modifies the data set is obligated to describe the types of modifications they perform. User specifically agrees not to misrepresent the data set, nor to imply that changes made were approved or endorsed by the U.S. Geological Survey.
