Dynamic Digital Maps

The complex nature of watershed-wide projects led to the application of a ddm template to the Souhegan River, NH. The Northeastern Instream Habitat Program's (NEIHP) project is a multi-disciplinary approach to mesoscale habitat assessment. The study involves intensive habitat mapping at eleven sites over three flows (cfsm) as well as fish sampling from within those locations. This data is merged using NEIHP's program Sim-Stream" to develop habitat rating curves which aid in potential mitigation options. Data on temperature, flow, bank and bed characteristics, macro-invertebrates, mussels, along with extensive photo documentation and other data are also combined in the interactive map.

The purpose of this Dynamic Digital Map is to (1) provide a visual tour of the field study area, (2) present details including various map products, images, and data in a dynamic and interactive way and (3) create a format for future study of the area.

The downloads are standalone programs that run without other software. The programs access their data [maps and images (in jpeg format), and movies] from a file server at UMass, using the web to transfer the images, thus requiring fast internet connections. All DDMs can access data from CDs or Hard Drives, if the data is available in those locations. To see any included movies, both Windows and Mac based computers must have the latest QuickTime Player installed (free from Apple for both platforms, at www.apple.com). Computers with less than 128 MB of free RAM will run these programs very slowly at best.
