Novel Ground Truth Method for Crop Fields Combining a Global Positioning System (GPS) and a Handheld Geographic Information System (HGIS)


Introduction

For the state of Arizona, Geographic Information System (GIS) map templates are created on an annual basis depicting the location of all potential crop fields.  These templates, along with a Global Positioning System (GPS) and Handheld Geographic Information System (HGIS), can be used to efficiently create a database of what crops were present during field visits and to assess the accuracy of crop classifications derived from remote sensing data.  These products can be easily created from inside a vehicle …
