GRS will hold a workshop on "Field Data Collection for the Development of Remote Sensing Ground-Truth" at the ASPRS Fall Conference in Orlando, Florida.
This workshop is designed to take the participant through a review of data collection methodologies, definitions, and pro and cons of different methodologies designed to assist the participant in designing and/or selecting the most appropriate reference data collection processes to suit their particular information needs, whether related to field training or accuracy assessment sites.
Methodologies presented will include ocular estimates, fixed area sampling, transect sampling, point sampling, and combinations of these approaches. The concepts of cover, closure, and frequency will be discussed. Techniques used to develop estimates of canopy cover and/or closure, trees per acre, quadratic mean diameter, average crown diameter, canopy structure, and species composition will be included. The estimation of categorical estimates will also be addressed, as well a discussion of potential bias and cost.
