Advanced GIS-Based Field Mapping Techniques

Advanced GIS-Based Field Mapping Techniques for Multi-Disciplinary Research

While technologies like satellite imagery and LIDAR have improved regional data collection, many USGS field researchers rely on sketches and manual paper map corrections. Emerging information technologies offer the potential to modernize field data collection. This project focuses on identifying opportunities for mobile computing technology in USGS research. more...


Cost-Benefit Analysis of The National Map

Cost-Benefit Analysis of The National Map

In 2003, the USGS Geography Discipline conducted a cost-benefit analysis of its new program, The National Map. The analysis team simulated the benefits to society from increased use of the improved digital spatial data provided by The National Map and weighed those benefits against the cost to develop and implement it. Several different reports and articles describe the research, modeling, and results of this cost-benefit analysis project. more...
