The Environmental Management Technical Center is responsible for developing a geographic information system for
the Upper Mississippi River System. To assure useful products are developed with a high degree of quality
assurance and quality control, the Analysis Team for the Long Term Resource Monitoring Program recommended
that standards and conventions for data organization, coding, storage, and transmission be written.
This document includes contract specifications for the acquisition of aerial photography, aerial mapping services
(contour mapping), digital scanning services, photo interpretation, vector digitizing services, and digital image
processing. In addition, file documentation standards are included to provide potential users with descriptive and
quantitative measures associated with the spatial data generated by the Environmental Management Technical
Center. Where applicable, specifications were written to conform to existing data bases that are available for the
Upper Mississippi River System. The specifications also require compatibility between contractor software and
software used by the Environmental Management Technical Center.
