Through the use of computer analysis technologies ----geographic information systems (GIS), geographic imaging, and digital image processing ---- the Cropland Data Layer Program is developing, on annual basis, wide-area-coverage (state and county level) land use classification images using medium-resolution LANDSAT satellites imagery. The final land use datasets show the spatial distribution of specific agricultural crops, natural vegetation and other land cover. The land use images reveals the locational variations and types of various land covers and can, therefore, be used in land cover identification, land use monitoring, land use updating and mapping. The NDASS is currently using crop specific numerical acreage estimates derived from the classified images as input into official state and county estimates. The datasets are distributed on CD-ROM and can also be viewed online. To order a CD-ROM send us your requests.

The project is also involved in extension educational program. The extension programming is centered around promoting the use and integration of remotely sensed land use datasets in agriculture and natural resource management, land use planning and other land development projects. This goal is achieved through training and demonstration in displaying and analysis of the datasets as well as basic GIS knowledge and skills. The educational activities are designed to help the general public, educators and youth better understand the concept and practical applications of the satellite imagery-based land use data.
