Working with Visual Navigation (VISNAV) & Land Use Land Cover (LULC) Data
VISNAV Land Cover (LC) is a raster dataset produced by MDA under contract to the NGA. The NGA has several Land Use Land Cover (LULC) products under the VISNAV program. Each product supports a variety of applications, such as broad area search, cartographic vegetation mapping, vehicle mobility modeling, engineering planning, and humanitarian disaster response. G-EGD currently hosts the 2013 update of the VISNAV LC dataset.
VISNAV LC Coverage
The original VISNAV LC was derived in 2010-11 from Landsat data. This product was last updated in 2013 with 2012 Landsat imagery. LULC classes include forest, urban, and agriculture, while Feature classes include golf courses, open pit mines, and sand dunes.
VISNAV LC Classification
The VISNAV LC product has 12 LULC classes and 13 feature classes. A different color is associated with each type of LULC classification or feature.
