What is GIS?

GIS stands for Geographical Information System.   What that means is that geometry and attribute information being collected has spatial locations associated (real locations on the earth).

Geometry are the physical features being represented.  These can be as points, lines, or polygons (areas).

  • Points many times represent an individual feature like a bin or a pole, but also be sample/survey locations.
  • Lines are linear features like rivers, roads, pipes, and power lines.
  • Polygons are area features like fields, zones, or lakes.

Attributes are the descriptors of the features for which they are associated.   These are sometimes name, length, type, and other information that helps understand the feature or the state of the feature.  In iCropTrak this can also be weather at the time of the attribution collections.

Locations are the points/vertices that make up the geometry.  They are represented inside iCropTrak as Latitude and Longitude in a sphere earth projection called WGS84 – Lat/Long.  Depending on the source and the layers in this area, sometimes the location also includes the elevation.

Formats for GIS information in iCropTrak can range from ESRI Shapefiles (.shp), Google KML (.kml), MapInfo MIF and TAB (.mif & .tab), .CSV, .XML, and many others.

Together they allow data collected to be filtered and combined not just by date and type, but also by absolute and relative  location.  Say the number of fields of corn within a 1 mile radius of where you are standing.
