The Use of a Geographic Information System in a Boll Weevil Field Evaluation Study

Glenn Wiygul and J. W. Smith


 
ABSTRACT

A Geographic information System (GIS) is a computerized method of linking geographic information (maps) with tabular data that is related to the map. The GIS that we developed has a field number, date, trap designation (A, B, C, etc.), the number of boll weevils caught in the trap, cotton cycle (or stage), last spray date, acres, and owner for each cotton field used in our large scale boll weevil control studies. This data is linked with a map of the area used in the control study. The map may be displayed and a cursor can be moved to the field for which the user wishes to view the data. The data that is linked to that cotton field may then be viewed. The technology allows the user to view relationships of data to map that cannot otherwise be easily obtained.
