Abstract:
|
Agricultural and environmental surveys typically involve collecting data on a sample of land units. While the foundations of sampling have relied on geographic information systems (GIS) for several years, survey data collection via a GIS interface is relatively rare. A computer-assisted geographic feature data collection instrument was implemented for the USDA's 2005 National Resources Inventory, a longitudinal survey of natural resources that involves repeated observations on area segments. Designing an approach that effectively records, displays and stores polygons that track change over time proved challenging. We will discuss methodological and design considerations in creating a GIS survey instrument based on this experience.
