The Historic Everglades

During my internship with the Everglades Foundation, I worked on a variety of GIS and mapping projects, including a historical ecology analysis of the Florida Everglades. In collaboration with the senior GIS Scientist at the Everglades Foundation, Rosanna Rivero, and Noosha Mahmoudi, a PhD student at FIU, a vegetation map of South Florida produced in 1913  was transformed for GIS compatibility using ArcGIS, Adobe Illustrator, and Photoshop. The final result is a polygon shapefile (illustrated above) that will be applied toward land cover change analysis and assessment of historical environmental conditions in the Everglades. The project was presented in the form of a poster at the 2009 NACIS conference in Sacramento, California, as well as the 2009 South Florida GIS Expo, where it won first place in the poster contest.

Optical Remote Sensing and Land Classification in Maine


This goal of this project was to classify three different types of satellite imagery (ASTER, Landsat ETM+, and SPOT) in terms of deciduous and evergreen forest, water, built structures, and cleared land. The study area is the region surrounding Augusta, Maine, in the north-eastern United States. A soft-classification method known as neural network classification was utilized. Rather than each pixel being assigned to one class, as in hard-classification methods, the soft-classification process assigns a degree of class membership to each pixel for the five land-cover types.
