New Approaches to Mobile Computing for Field Data Collection
Sarah Nusser, (Iowa State University),


Recent research in mobile computing for survey data collection has focused on the use of geospatial data formats in small screen environments, including augmented vision and wearable computers, and on flexible infrastructure models that take into account features associated with a data collection setting. We will discuss studies that explore how map data and GPS position indicators presented in mobile computing environments affect the ability of field data collection staff to plan work and locate sample units. Results indicate that multiple tools are needed to address the variability that exists in spatial abilities across field staff. This can be accomplished by presenting a variety planning and navigation aids on the map display. This research is being used to propose infrastructure models for delivering usable geospatial data products and functions to the field via adaptable systems that accommodate a variety of field computing and application settings.
