SummaryProject: eSPACE Ė emergency Spatial Pre-SCAT for Arctic Coastal Ecosystems Project Objectives: a) Identify and map shoreline characteristics, coastal habitats, and resources at risk in the Arctic (3 pilot sites). b) Develop methods using EO data and compare it to current protocol (video by helicopter). c) Establish partnerships to improve preparedness to Environmental Emergencies and habitat conservation in the north. Methodology: Traditional data development for shoreline classification and sensitivity analyses include manual interpretation of oblique videotape imagery collected in a helicopter at altitudes less than 400 feet. This method has been successfully applied to the majority of southern Canadian coastlines. This project will develop EO data classification procedures to support shoreline segmentation and sensitivity analyses in the Arctic and verify that the products are as reliable as the traditional approach. Practical experience mapping coastlines in the Arctic suggests that integrated use of optical and SAR imagery improves shoreline discrimination. In areas where erosional coastal types are dominant, a combination of multi-scale, multi-temporal imagery and more sophisticated pattern recognition techniques are more appropriate for coastal type discrimination. This project will focus on Canadian and European (and associated) sensors that are freely available for Canadian government departments. Optical analysis will be completed using SPOT 5 acquisitions from 2005-2010 currently available on GeoBASE and archived Landsat imagery where appropriate. New acquisitions will be focused on Radarsat-2, TerraSAR-X, MERIS, and ALOS sensors. Research will be conducted using airborne hyperspectral and LIDAR systems to support future potential space-borne systems (i.e. ENMAP). Advanced radar techniques including InSAR, Polarimetry and PolInSAR and innovative image analyses (i.e. object-based) will also be explored to produce the high resolution shoreline classification. Expected Results and Outputs: a) Spatially explicit coastal sensitivity and segmentation of shoreline maps for 3 pilot sites (1- Mackenzie River Delta and Beaufort Sea, 2- Hudsonís (Churchill port) and James Bay; 3- Part of Labrador Coast) b) Improved capacity to use EO resources to support ECís mandate in the Arctic. c) Business case for full implementation of satellite coastal mapping for emergency preparedness and habitat conservation in Canadaís north. Funding: Funding for this project is predominantly from three sources: MorseArctic Initiative (Canadian Space Agency); other Federal Government departments and industry partners. To realize the deliverables and expected results of this pilot project, a total budget of $3.3 million is estimated over 4 years from all project partners.
