  1. Agricultural Weather Assessments Agricultural Weather Assessments World Agricultural Outlook Board World Agricultural Outlook Board GEOSPATIAL APPLICATIONS IN AGROMETEOROLOGY An Overview of the USDA World Agricultural Outlook Board Geographic Information System Harlan Shannon Meteorologist U.S. Department of Agriculture Office of the Chief Economist World Agricultural Outlook Board Washington D.C., U.S.A.

  2. Agricultural Weather Assessments Agricultural Weather Assessments World Agricultural Outlook Board World Agricultural Outlook Board GEOSPATIAL APPLICATIONS IN AGROMETEOROLOGY Introduction • Several analytical techniques can be used to assess agricultural weather • time series analyses • analog comparisons • maps • Historically, many maps were static & depicted just one variable, making it difficult to: • overlay data sets • visualize and evaluate relationships • easily assess crop weather conditions • Geographic Information Systems (GIS) have helped overcome these obstacles

  3. Agricultural Weather Assessments Agricultural Weather Assessments World Agricultural Outlook Board World Agricultural Outlook Board GEOSPATIAL APPLICATIONS IN AGROMETEOROLOGY GIS Described Simple GIS • GIS defined: integrated system for organizing, displaying, and analyzing spatial data using computers and compatible technologies • GIS incorporates quantitative data directly into the system, helping users: • overlay multiple data sets • create precise maps • statistically evaluate relationships • Numerous organizations use GIS to study, monitor, and model agricultural and meteorological processes Robust GIS

  4. Agricultural Weather Assessments Agricultural Weather Assessments World Agricultural Outlook Board World Agricultural Outlook Board GEOSPATIAL APPLICATIONS IN AGROMETEOROLOGY WAOB Geographic Information System • Software • ArcView 3.x – older software still used to run some operational applications • ArcGIS 9.x – majority of operations transitioned to this newer software • Hardware • Pentium D desktop computers • 3.4 GHz processing speed • 2 GB RAM • Windows XP operating system • PCs connected via local area network • Oracle 11g database

  5. Agricultural Weather Assessments Agricultural Weather Assessments World Agricultural Outlook Board World Agricultural Outlook Board GEOSPATIAL APPLICATIONS IN AGROMETEOROLOGY GIS Activities Manually generate maps of important agricultural & meteorological variables Automate product creation to maximum extent possible Overlay & analyze agrometeorological data sets, establish relationships, & determine impacts where applicable

  14. Agricultural Weather Assessments Agricultural Weather Assessments World Agricultural Outlook Board World Agricultural Outlook Board GEOSPATIAL APPLICATIONS IN AGROMETEOROLOGY Automating Applications • Crop production areas shift slowly over time, thus maps of major crop areas are updated infrequently • automated updates not necessary • In contrast, crop progress & conditions vary on much shorter time scales, requiring more frequent map updates • manual map production can be time consuming and tedious if a large number of products are required • Automation is necessary to effectively and efficiently produce such products

  16. Agricultural Weather Assessments Agricultural Weather Assessments World Agricultural Outlook Board World Agricultural Outlook Board GEOSPATIAL APPLICATIONS IN AGROMETEOROLOGY VBA Macros • Object-oriented programming language, enables users to automate various tasks associated with mapping • Examples of automation: • importing data • spatial analysis (e.g., contouring) • defining map scale/extent • annotation • creating a map legend • exporting/printing a map
