Niger is associated with the Sahel Region. Keywords: CUI, Crop Use Intensity, Niger, NG, Africa, Sahel region. Purpose: This data set was developed as a tool and is to be used to monitor crop conditions and crop production. It was designed to be used in conjunction with Normalized Difference Vegetation Index (NDVI) data. In addition, the data may be used to disaggregate agricultural and/or population statistics spatially. Supplemental_Information: Procedures_Used: The agricultural overlay was prepared through interpretation of Landsat 5 Mulitspectral Scanner (MSS). Landsat MSS bands 1, 2 and 4, corresponding to multispectral bands green, red and near infra-red, are represented by the primary colors blue, green and red respectively (standard false-color composite). The data is subjectively based upon the interpreters knowledge and ancillary data. The data lacks complete ground truth by field checking. Revisions: This data set has been altered to conform to the standard boundary file chosen for Niger, Africa. The ARC IDENTITY utility was used to conform the CUI data set to the country's ADMIN1 boundary. file. The resulting file was then processed to eliminate un-labeled polygons along the international boundary using the ARC ELIMINATE command.
