Title: Evaluation of high resolution airborne imagery and global positioning systems for monitoring changes in agroecosystems
Author: Protz, R.; VandenBygaart, A. J.; Wood, M. D.; Hulshof, B. G. A.
Abstract: High resolution Compact Airborne Spectral Imager (CASI) data was collected of three of the paired fields within the 'Soil Organisms As Bioindicators Of Agronomic Practices' project sites. High resolution elevation data was obtained with the Leica Global Positioning System (GPS) of each of six fields. The imagery and elevation data have been registered. Soil profile sites have been located to within one meter accuracy in the imagery. Surficial soil organic matter content has been correlated to spectral response. In an associated project Landsat thematic mapper imagery (30 m resolution) has been registered to the road network for the 10 counties in southern Ontario. The size of each field has been measured in hectares. Each large agricultural field has been numbered within major physiographic region and township. To map changes in soil organic matter (SOM) in the future, agricultural fields can be chosen randomly within the arc/info Geographic Information System (GIS). Samples will be chosen by slope position. Characterization of soil organic matter within pedons on various slope positions within each physiographic region will be done periodically in the future. Monitoring of tillage practices over time will aid in the selection of a method for soil sampling to measure the state of soil organic matter.
