Title:
Cropland Data Layer 2021, Minnesota
Abstract:
The United States Department of Agriculture (USDA), National Agricultural Statistics Service (NASS) Cropland Data Layer (CDL) is a raster, geo-referenced, crop-specific land cover data layer.
This is the 2021 NASS USDA CDL dataset for Minnesota. The dataset was clipped and downloaded using the USDA NASS CropScape online web application: http://nassgeodata.gmu.edu/CropScape/
The Minnesota Department of Agriculture (MDA) did minimal processing on this dataset to make more useful for Minnesota-specific work. The lineage section describes these steps taken, but the full description of the Cropland Data Layer can be found in the NASS USDA Metadata at https://www.nass.usda.gov/Research_and_Science/Cropland/metadata/2021_cultivated_layer_metadata.htm
Purpose:
The purpose of the Cropland Data Layer Program is to use satellite imagery to (1) provide acreage estimates to the Agricultural Statistics Board for the state's major commodities and (2) produce digital, crop-specific, categorized geo-referenced output products.

Lineage:
Dataset was downloaded from the USDA NASS CropScape online web map application using the following procedure:
1. Used USDA NASS CropScape online application: http://nassgeodata.gmu.edu/CropScape/
2. Set Area of Interest to predefined State of Minnesota
3. Downloaded data, specifying Projection to be: UTM Zone 15 in dialog (WGS84)
Post processing steps were:
1. Data were downloaded as in GEOTIF (.tif) format with color map and were imported as an Esri Raster into Esri File Geodatabase
2. Data were transformed from WGS84 to NAD 83.
3. Statistics were run on the Raster to add a "Count" field to the Value Attribute Table (VAT) to provide a total count of cells for each land cover value. Use caution in comparing cell counts between this CDL layer and other years because cell size changes varies between years.
