Geographic Information Systems Services:
RTI provides the following geographic information systems (GIS) related services, including
- Environmental management information systems
- GIS support for social and health policy research
- Automated mapping
Geospatial database design and development
- GIS for international development
RTI develops custom environmental management information systems for clients whose mission includes the management of large and active environmental databases. Using commercial, off-the-shelf GIS and database management tools, along with sophisticated geospatial and non-geospatial database design techniques, RTI builds these systems to meet the specific requirements of our clients. RTI also offers a standard Web-based environmental information management system called the GEOgraphic Data Evaluation System (Geode™). Developed by RTI, Geode is a Web-based data querying and mapping tool developed by RTI that allows instant access to environmental data for use in decision making, analysis, compliance support, and presentations. It is especially strong in managing and manipulating groundwater data and complex hydrogeologic systems. Users can log in to Geode from any location to query their databases and can easily toggle between maps and databases established for different facilities using either a drop-down menu or Geode’s global mapping page.
RTI provides basic and applied research services in a wide variety of social and health policy fields. Many of these research activities benefit from the use of GIS to store, manage, and analyze data. GIS is used in many capacities in these projects, such as siting the best location for field sites that minimize travel distance for survey participants; supporting survey data collection through the production of maps to be included in survey instruments; analyzing medical and health survey data; analyzing and assessing economic impacts of environmental regulations; and comparing demographic variables in health and social policy models. RTI has also implemented GIS mapping and analysis on a number of crime-mapping research projects for the Department of Housing and Urban Development.
RTI’s GIS program develops automated mapping systems to support geospatial applications and research activities that require large numbers of high-quality and consistent maps to support fieldwork. Automated mapping systems have been developed to support very large nationwide household surveys in which tens of thousands of detailed maps must be produced in a short time frame. These systems are constructed to support fully automated production for 24 hours a day, 7 days a week. They also support interactive mapping production where visual review of areas to be mapped is necessary to produce maps that meet quality and clarity requirements. RTI’s GIS staff have more than 15 years of experience making use of U.S. Census Bureau Topographically Integrated Geographic Encoding Reference (TIGER) line files in map production environments. In addition, RTI has large nationwide geospatial databases on-line for use in automated mapping systems.
RTI staff have many years of geospatial database design skills and experience, which we use to design and develop geospatial databases to support research and applications. Whether our clients require small, relatively simple geodatabases or large, complex geodatabases, our experience allows us to design around the common pitfalls, problems, and inefficiencies that may not be readily apparent in geospatial database design. We also have experience with a wide variety of existing geospatial data (e.g., TIGER, the National Hydrography Dataset [NHD], the National Elevation Dataset [NED], National Land Cover Data [NLCD], and digital line graph [DLG]) available from government agencies.
GIS is one of the cornerstone’s of RTI’s Local Governance Project for the United States Agency for International Development (USAID) in Iraq. GIS has been used to generate large quantities of basemaps for use by RTI staff and other contractors in Iraq to aid in basic navigation and location activities. As RTI continues to help Iraqis develop civil society institutions, GIS is used to monitor and evaluate the status and success of various strategies and initiatives that are designed to help establish democracy and local government operations. In other countries, RTI is developing GIS capabilities to enhance monitoring and evaluation of projects involving health and education support.
