Geographic Information Systems
(GIS) Based Mapping

Crop Care Associates Inc. can provide a wide range of Geographic Information Systems (GIS) based mapping services.

We can provide:

  • Color classified slope maps
  • Color classified aspect/exposure maps
  • Aerial color photographs & infrared (IR) images
  • Normalized difference vegetative index (NDVI) images.

The slope and aspect/exposure maps are useful for determining plantable acreage in hilly or mountainous terrain. The slope is measured and presented in 5% colorized slope classes (i.e. 0-5%, 5-10%, 10-15%, etc.). Slope limit criteria can be set by the client (i.e. county slope regulations) and the area of land in each slope class and/or the slope within a series of slope classes (i.e. 0-30%) can be calculated. Additionally, county soil survey data may be super-imposed onto the slope data, and the average slope for each soil type may also be calculated. This is particularly useful in areas where planting and erosion control ordinances are based on average slope of specific soil series.

The IR and NDVI images are useful for the diagnosis and determining the extent of field disorders (soil, pest, and diseases). The NDVI is a process in which an IR image is mathematically manipulated to exaggerate the differences in the reflectivity of green plants and is very useful in distinguishing small differences in plant growth patterns due to differences in plant nutrition, leaf area, soil properties, drainage problems, pest, and diseases.

Using aerial photography and geo-positioning satellites (GPS) we are able to develop detailed block maps with accurate (+/-3%) calculations of acreage for agricultural managers. We can super-impose county soil survey data and block information (block name, variety, rootstocks, plant densities, planting dates, etc.) onto the maps.

Crop Care Associates Inc. can develop detailed colorized contour maps of soil properties (pH, EC, SAR, texture, N, P, K, Ca, Mg, K, Fe, Zn, Cu, Mn, etc.) from soil profile and soil chemistry data. We can then use these maps to design blocks, which contain a high degree of uniformity of soil properties.
