Visualization of a Crop Season the Integration of Remotely Sensed Data and Survey Data

摘要

A visual map display of the complete 1999 growing season will be created for internal use on NASSs Intranet using GIS to display crop development and condition as supplementary information to the standard NASS collected survey data. The crop information comes mainly from expert opinion of USDA agricultural extension agents across the country. They submit weekly reports to NASS on crop development and condition which is summarized at the state level and published for external use in the Crop Progress Report and in the Weekly Weather and Crop Bulletin. Using this information for a selected group of states at the county level with the purpose to expand the Agency GIS capabilities for internal analysis, crop progress of the specific stages of crop development for corn and soybeans, along with vegetative index maps, farmer reported yield data at the county level, weekly growing degree data, and NASS county estimate data provides a good visual overview of a growing season.
