Treatments are monitored with the use of Global Positioning System (GPS) technology. Routes are pre-mapped within the treatment areas and loaded into two GPS units per application vessel. By using two GPS devices, the applicator is able to monitor their progress within the treatment area from multiple perspectives. Additionally, using two devices ensures no loss of data.
GPS tracks are uploaded to ArcView, a mapping program, at the end of each treatment day for review. Tracks are analyzed for thoroughness of the treatment and used to calculate the actual area treated to ensure that the desired application is achieved. Based on survey results, recommendations can be made for the control of any undesirable plants.
