2. Anthropogenic Change Detection in Alberta An anthropogenic footprint is defined as “the extent of any land cleared or directly modified by human activity”. It does not include indirect effects such as pollution, edge effect etc. The information is crucial to government administration, industry operations, and environmental monitoring. Accurate, detailed and timely mapping of these features over vast geographical areas is a major challenge in resource management and regulation. However, the scale and complexity of geospatial data to be acquired and analyzed can be formidable due to the required manpower, costs, and technology involved. Introduction

6. Anthropogenic Change Detection in Alberta Image-based challenges: Satellite image mosaic varies in data quality due to varying acquisition dates It can be very difficult to differentiate some of the footprints Location-based challenges: Features very large in size and features that are long and linear However, only segmentation or image classification is not enough to overcome all the challenges that well pad delineation have for high accuracy shape detection. It can only solve one problem of the delineation process. Methodology

16. Anthropogenic Change Detection in Alberta The anthropogenic footprint detection procedure performs well in characterizing the change in the study sites from 2007 through 2011. SPOT 5 Panchromatic image data provides a cost effective and efficient alternative to multispectral imagery for mapping anthropogenic footprint. Several spatial image processing techniques (morphological analysis and texture features) and the utilization of human interpreters for quality control was observed to significantly improve detection results. The focus of future work is to combine all procedures into a single intelligent system for change detection map creation. Further improvement of detection algorithms as well as automated QC procedures for removal of falsely detected areas will also be investigated. Conclusion
