PREVIEW-IMS: Project for Risk Evaluation, Vulnerability Indexing, and Early Warning
The Global Resource Information Database (GRID)-Geneva, part of the United Nations Environment Programme Division of Early Warning and Assessment, collects and analyzes environmental data and disseminates the information to raise awareness and help communities with decision making processes. Among its many projects and tasks, GRID-Geneva provides early warning on environmental threats and problems and uses GIS and remote sensing for mapping, monitoring, and sustainable use of natural resources. PREVIEW-IMS is a MapObjects IMS tool that enables the visualization of data on natural disasters including earthquakes, fires, floods, cyclones, and tsunamis relative to other layers of information about cities, natural parks, rivers, components of vulnerability, population density, human development index, gross domestic products, elevation, and land cover.
Canoe and whitewater enthusiasts can access to search all the major rivers within the Commonwealth of Virginia for their status based on U.S. Geological Survey gauge information. TerraLogic, Inc., designed the system, which implements ArcIMS. Visitors to the site can type in a river name and view characteristics of river runs including the velocity, width, distance, skill level, kinds of scenery and hazards, and the number of portages. The system will map put-ins and take-outs for a run. Along with the usual search and zoom tools, another tool measures distances.

River Run
The Lower Cape Fear River Program is a large-scale water quality assessment program covering the Cape Fear estuary and lower watershed. River Run, administered by the University of North Carolina at Wilmington, Center for Marine Science, is for viewing and manipulating data collected from stations along the Cape Fear River Basin. Variables, such as dissolved oxygen, ammonia, turbidity, and temperature, can affect the ecology of the river. The ArcView IMS mapping application enables users to find inputs into the river and track their effects.
