The Delaware Geological Survey Cartographic Information Center has made the DGS a focal point for questions concerning the availability of all types of aerial photography, thematic maps, planimetric maps, topographic maps, historic maps, LANDSAT imagery, space imagery, side looking aerial radar imagery (SLAR), and geodetic control. Sources of maps, charts, aerial photography, boundary mark information, and vertical geodetic control can be obtained for your area of interest within the State through the Center's computer-searchable data bases. In addition, through the Center's affiliation with the U. S. Geological Survey's National Cartographic Information Center (NCIC) in Reston, Virginia, we can locate all cartographic materials covering the United States produced by federal agencies.
The DGS, in response to the needs for efficient storage, manipulation,retrieval, and report-generating capability, has proceeded with the conversion of the paper file data base to an integrated automated geologic, hydrologic, and mineral resource management information system. It is necessary to organize data in a systematic and standardized fashion for efficient entry into the automated system. To accomplish this, the DGS has made major revisions in the data recording and filing systems.
This report contains the new DGS data schedules, describes the information that should be recorded on each schedule, and presents instructions for preparation of the schedules. The schedules are designed to make various kinds of data consistent with the input format screens utilized in the automated system.
The types of schedules described include:
2. Water Level
3. Lithologic Log
5. Aquifer Test
6. Geophysical Log
7. Field Water Quality
8. Laboratory Water Quality
9. OCS Well

The DGS is, by statute, the state agency responsible for entering into agreements with its counterpart federal agencies, including the U.S. Geological Survey, the USGS Office of Minerals Information (formerly the U.S. Bureau of Mines), and the Bureau of Ocean Energy Management, Regulation and Enforcement (formerly the U. S. Minerals Management Service), and for administering all cooperative programs of the State with these agencies. The DGS also works with many in-state and out-of-state partner agencies and organizations.
