The gathering of ecological data for the purpose of establishing baseline inventories is facilitated by the use of remote sensing, geographic information systems, and global positioning systems (GPS). The use of these technologies in the study of submerged aquatic vegetation (SAV) is quickly becoming common practice. In order to assist in the development of a standard methodology, the techniques used in an SAV study on the lower Connecticut River are described. Issues with GPS accuracy and with the ground-truthing of aerial photographs are considered.
