Geographic Information System (GIS)
Links and Data

The PIE LTER research program is involved with developing GIS datalayers and databases for the watersheds and waterbodies of the Plum Island Sound Estuary. GIS development has focused on understanding the impact of land use change on the watersheds in northeastern Massachusetts and the geomorphological evolution of tidal creeks in the Plum Island Sound Estuary.

Our GIS development has greatly benefited from the use of the Massachusetts Geographic Information System developed by the Commonwealth of Massachusetts Office of Geographic and Environmental Information. Databases and datalayers have been developed by colleagues at The Marine Biological Lab, Clark University and The University of New Hampshire.

Massachusetts Geographic Information System

Clark University Ipswich River Watershed (GIS)

There are two faculty members at Clark University who are members of the PIE research team. They are Robert Gilmore Pontius Jr (rpontius@clarku.edu) and Colin Polsky (cpolsky@clarku.edu). Since 1999, Pontius and his students have been creating GIS-based methods for land change prediction. They develop novel techniques of model validation and land change assessment. Much of their work can be found at www.clarku.edu/~rpontius. Most of the maps below were obtained from the Massachusetts Geographic Information System and formatted to facilitate simulation modeling of changes among land cover types over time. Future scenarios of land change are used to make scenarios of nutrient loading. Polsky joined the PIE team more recently. He and his students study the vulnerability of human populations to the possible over-exploitation of water and land.

Clark University GIS data for the Ipswich watershed has been developed in IDRISI with most files raster based. Many will open using ArcGIS 10.x; please contact us if you have questions

Updated June, 2013. Files are now downloadable in zip files which include all necessary GIS files, original FGDC metadata Word documents, and EML-compliant metadata in XML format.

University of New Hampshire River GIS

University of New Hampshire researchers are developing river network hydrological and biogeochemical models to explore how land use change, climate variability and change, and surface water management affect water and nutrient fluxes throughout the basin and to the estuary. A central requirement for this model is a digital river network that is used to simulate surface water flow paths from source areas to the coastal zone. The river network is grid-based at a 120m by 120m resolution. The following GIS files define important characteristics of the river network that drains to the Plum Island Estuary, including flow direction, cell length, distance from cell to ocean, upstream contributing area for each grid cell, and the stream order to which the grid cell first enters the surface water network. The gridded river network is used to explore scientific questions regarding the role of different land uses in defining nutrient loading, and the role of river systems in controlling exports to the coastal zone.

UNH GIS data layers currently available consist of Arc ascii (raster digital data) files, with a corresponding Microsoft Word metadata file which follows the Federal Geographic Data Committee (FGDC) metadata format, the same template as used by Clark University, and an EML-compliant XML file of metadata for each file.
