Description: 

My research focuses on the influence of suburban neighborhoods on amphibians in small pond communities. In general there are two spatial problems to deal with in suburban small ponds. The first is that small ponds are nearly impossible to detect from space. The second is that available land cover data are too coarse of a grain to detect the necessary important land cover heterogeneity (houses, yards, etc.). To the first problem, I have used GPS to map the perimeter of small ponds in GIS, though this relies on a priori knowledge of pond location. For the second problem, I am using 2013, high resolution satellite global basemaps in GIS to trace the footprint of important suburban land cover (houses and yards) surrounding ponds. While this certainly yields a much more interesting and accurate depiction of the landscape, its application will require a nontrivial amount of time. My goal is to explore remote sensing tools to see if there are better methods of detecting small wetland habitats as well as their fine-grain suburban matrices.
