Abstract
Current safety, environmental, and economic concerns, as well as scientific issues require accurate mapping of shorelines and particularly precise monitoring of their spatial changes. The extent and remoteness of the Canadian coasts require rapid techniques for their mapping and monitoring their spatial changes over time. Aerial and satellite remote sensing sensors significantly contribute to the data acquisition phase by providing extended and frequent coverage. The delivery of outputs in shorter times along with the limited resources requires the development and use of efficient techniques and automated processes. Given the nature of the data types (raster/imagery, vector), in this paper a range of image analysis and spatial analysis techniques and tools are examined, which are applied in the operations for feature recognition and planimetric extraction and the detection of planimetric spatial change using image data. Their potential, applicability and usefulness towards improving mapping procedures is demonstrated and discussed using co-registered digital aerial photography and satellite IKONOS, QuickBird ortho-imagery for the area of Sachs Harbour, Northwest Territories, Canada and RADARSAT for the area of Gagetown, New Brunswick, Canada. This work has been conducted in the project “Regional Climate Change Impacts: Geoscience Information for Other Government Departments” under the Program “Reducing Canada’s Vulnerability to Climate Change” of the Earth Science Sector of Natural Resources Canada.
