Making well-informed, responsible decisions is critical to shaping the nation's transportation infrastructure. Geospatial data are a foundation for relevant and critical information for planning, engineering, asset management, and operations associated with every transportation mode at all levels of government and administration. One definition of geospatial data is found in the executive order on coordinating geographic information and access: "'Geospatial data' means information that identifies the geographic location and characteristics of natural or constructed features and boundaries on the earth. This information may be derived from, among other things, remote sensing, mapping, and surveying technologies. Statistical data may be included in this definition at the discretion of the collecting agency." Extracting these data, transforming them, and making them available to decision makers has dramatically increased in importance as all modes and levels of government face increasing responsibility for improving efficiency while maintaining mobility, improving safety, and anticipating and addressing security threats.
