Mapping and change detection for boreal wetlands of North America based on JERS and PALSAR data

We have been developing high-resolution thematic maps of wetlands throughout the North American boreal regions. We assemble a wetlands map for each region based on data collected during the late 1990s, then construct a second map based on data collected during the late 2000s. Comparison of the two maps then makes it possible to assess changes that have occurred over the course of the intervening decade..
