Mapping Regional Crop Production,

Soils, and Climate

Stuart H. Gage, state representative to NCR-148
Michigan State University

Assessing the role that organisms play in crop production requires an understanding of the drivers of plant productivity. This must be done in the presence and the absence of the herbivores. Data characterizing crop production can aid those interested in crop losses caused by organisms when they are transported into the area on weather fronts or if they are long term residents. Over the past few years Michigan has led with Illinois in the development of a set of spatio-temporal data including regional soils, weather and crop productivity in the NC94 regional project on weather and agriculture. These data sets provide one of the most complete records of temporal and spatial variables that characterize the dynamics of agriculture in one of the most important agricultural production regions in the United States. The data are primarily based on soils, weather and crop production at the county level or resolution. To gain use and access to these data Michigan and cooperating states have developed a strategy to organize the data into logical relational databases so these data can be analyzed and mapped. Summaries of the database characteristics of the crop databases can be found in Gage (1990). Mapping has been one of the activities of the Michigan involvement in NC94. A system to map crop productivity, using current Geographic Information System technology, was presented by Gage (1993). Various other integrated technologies have been developed to map and visualize the integrated databases developed by NC94 have been presented at past NC94 meetings and at other locations (Gage and Andresen 1996; Gage 1996; Gage and Robertson 1996).

One of the fundamental issues faced by the agricultural scientific community is logical and relatively easy access to the databases developed by the NC94 subcommittee on database creation. To this end, Michigan has developed an extension to the ArcView3 Desktop Geographic Information System (ESRI 1996). The NCR extension to ArcView3 uses the Spatial Analyst and links to the Access Relational Database System (Microsoft 1996). The following characteristics are incorporated into the NCR Extension: Database accessibility; Multiple table generation; polygon or surface mapping; regional or individual state data selection; automated surface interpolation; theme averaging and summation; standardizing legends across themes; and an automated map naming system. The NCR Extension is designed to lead the user through the process of map creation. The user is asked for the type of map desired (grid or polygon) and the area desired for mapping (region or a specific state in the North Central Region). Next the user is provided a list of database table available including Crops (Corn, wheat, soybeans); Weather; Soils, or Solar Radiation.

When mapping, the user is asked to select the variable in the database. In the case of crop production, the type of production and the cropping practice. Next, the user is requested to select a year or series of years in the database associated with each selected variable. Maps are created at this point, and the length of processing time depends on machine speed and the number of years selected for mapping. Map legends with nine categories are automatically produced, the values ranging from the minimum to the maximum for the selected variable. Users can develop custom legends to standardize across maps and a utility is provided to facilitate standard legend processing. Outlines of state boundaries or county boundaries can be included. These vector shape files can be overlaid on the grid maps if the grid interpolation is used. Once selected variables are mapped, the user has the full flexibility of manipulating maps using the many powerful features of ArcView3. The NCR extension is developed in the Avenue Programming Language (ESRI 1996). The NCR Extension consists of several thousand object oriented Avenue commands (Gage and Thomas 1997).
