Nebraska GAP land cover classification detail

Nebraska GAP land cover mapping used the National Vegetation Classification System (NVCS) with 1991-1993 Landsat Thematic Mapper (TM) imagery as primary source data.

Imagery was acquired through the Multi-Resolution Land Characteristics (MRLC) Consortium. Preprocessing was done at the Earth Resources Observation Systems (EROS) Data Center. Nebraska GAP map accuracy meets USGS 1:100,000 standards . A total of 18 scenes were needed to cover the state of Nebraska. A multi-date classification technique was developed to generate the land cover map and ancillary datasets were subsequently used to improve discrimination among land types.

Land cover classification and dominant land cover classification maps were produced:
