Prioritizing Geologic Mapping with MCDA
When the Pennsylvania Department of Conservation and Natural Resources sought a more methodical and transparent decision-making process to prioritize geologic mapping activities, it turned to multi-criteria decision analysis (MCDA). The approach provides methodology and techniques for weighting and scoring multiple criteria to reach a conclusion in complex decision problems. 
Understanding Tropical Deforestation with Remote Sensing
and GIS Modeling
More than 60 percent of the primary forest of tropical ecosystems has already been lost, and government agencies are struggling to prevent further destruction. The disruption of environmental equilibrium is reflected in problems affecting agriculture, water management, marine resources, wildlife, and human health. In Honduras, GIS techniques, lifestyle surveys, and satellite imagery of forested areas all helped to determine the variables that predict deforestation behavior among rural families.
Analyzing Eye Movement During Geospatial Data Inspection
Human analysts perceive visual data through intensive eye movements, which subconsciously select the most distinctive features in an image to reduce overall ambiguity about the observed scene. A study of human analysts' performance during geospatial data inspection explores the feasibility of gaze tracking as a disambiguation tool in the visual search for a target in high-resolution imagery.
Satellite-Based Crop Management
All stakeholders in agriculture — including producers, processors, resource managers, the marketing and finance sectors, and the government economies — need timely and reliable information on crop acreage, yield prediction, and production estimation for tactical and strategic decision making. In India, a remote sensing and GIS-based approach proves to be an accurate method for estimating yields and monitoring the health of sugarcane crops.
