The Delaware DataMIL is Retired

The Delaware DataMIL, an online web mapping application that has provided accurate, up-to-date Delaware Geospatial Framework (basemap layers), current and historic aerial photography, and topographic maps for Delaware since 2002 is retired as of June 30, 2013. Originally built as a state of the art, crowd source editing and map delivery system and pilot project for the US Geological Survey National Map, the DataMIL is being replaced by newer mapping technology through the Department of Technology and Information (DTI) which will have a new system in place shortly.

Development of a High Water Mark Database and Display System for Coastal Flooding Events in Delaware

Water over the road at Bethany Beach, DE
Project Contact(s):

DGS is building a database and web distribution system to collect, manage, and display high water marks (HWMs) that are observed throughout Delaware as a result of flooding events. Historical peak water levels can be extracted for past storms or for a selected geographic area. Development is being done in partnership with the Office of the Delaware State Climatologist, the Delaware Environmental Observing System (DEOS) and the Delaware Environmental Monitoring and Analysis Center (DEMAC).

The Delaware Geological Survey published a new geologic map of southwestern Sussex County

The Delaware Geological Survey (DGS) has published a new geologic map of southwestern Sussex County titled Geologic Map of the Sharptown, Laurel, Hebron, and Delmar Quadrangles, Delaware.

DGS Geologic Map No. 22 (Sharptown, Laurel, Hebron, and Delmar Quadrangles, Delaware) Dataset

DGS Geologic Map No. 22 (Sharptown, Laurel, Hebron, and Delmar Quadrangles, Delaware) Dataset

This vector data set contains the rock unit polygons for the surficial geology in the Delaware Coastal Plain covered by DGS Geologic Map Series No. 22 (Sharptown, Laurel, Hebron, and Delmar Quadrangles, Delaware). The geological history of the surficial geologic units in western Sussex County is that of deposition of the Beaverdam Formation and its subsequent modification by erosion and deposition related to the sea-level fluctuations during the Pleistocene. The geology reflects this complex history by the cut and fill geometry of the middle and late Pleistocene deposits into the Beaverdam Formation. The geology is further complicated by periglacial activity that produced dune deposits and Carolina Bays in the map area, which modified the land surface.

The geology reflects this complex history by the cut and fill geometry of the middle and late Pleistocene deposits into the Beaverdam Formation. The geology is further complicated by periglacial activity that produced dune deposits and Carolina Bays in the map area, which modified the land surface. Mapping was conducted using field maps at a scale of 1:12,000 with 2-ft contours. Stratigraphic boundaries drawn at topographic breaks reflect detailed mapping using contours not shown on this map.

Delaware Geological Survey releases new geologic map of the Trap Pond area

The Delaware Geological Survey (DGS) has published a new geologic map of the Trap Pond and Pittsville areas in central Sussex County titled Geologic Map of the Trap Pond and Pittsville Quadrangles, Delaware.

DGS Geologic Map No. 21 (Trap Pond and Pittsville Quadrangles, Delaware) Dataset

DGS Geologic Map No. 21 (Trap Pond and Pittsville Quadrangles, Delaware) Dataset

This vector data set contains the rock unit polygons for the surficial geology in the Delaware Coastal Plain covered by DGS Geologic Map Series No. 21 (Trap Pond and Pittsville Quadrangles, Delaware). The geological history of the surficial units of the Trap Pond and the Delaware portion of the Pittsville Quadrangle was the result of deposition of the Beaverdam Formation and its subsequent modification by erosion and deposition related to the sea-level fluctuations during the Pleistocene. The geology reflects this complex history by the cut and fill geometry of the Middle and late Pleistocene deposits into the Beaverdam Formation. The geology is further complicated by periglacial activity that produced dune deposits and Carolina Bays in the map area, which modified the land surface. Surficial geologic mapping was conducted using field maps at a scale of 1:12,000 with 2-foot contours. Stratigraphic boundaries drawn at topographic breaks reflect detailed mapping using contours not shown on this map.

OneGeology

DGS participates in OneGeology initiative
Project Contact(s):

OneGeology (http://www.onegeology.org/) is an international effort to make available digital geologic map data from around the world. DGS participates in OneGeology by submitting two web map services, one for 1:100K scale surficial geologic units and one for 1:100K scale surficial geologic contacts. These services are open and interoperable (supporting both WMS and WFS protocols) with data attributes in GeoSciML-Portrayal format.

Delaware State and County Boundaries

Delaware State and County Boundaries

Three datasets are included: the official state boundary line, the county boundary lines, and the land/shore outline. These geospatial data files comprise the bounding lines relating to the political boundary delineation for the State of Delaware as well as the shoreline taken from the 2002 orthophotos of Delaware.

Elevation Contours Dataset for Delaware

Elevation Contours Dataset for Delaware

Elevation contours at 2 foot intervals for the State of Delaware were produced for New Castle and Kent Counties based on the 2007 LIDAR) and for Sussex County (based on the 2005 LIDAR.) Data are in line shapefile format.

GM18 Geologic Map of the Bethany Beach and Assawoman Bay Quadrangles, Delaware

Geologic Map of the Bethany Beach and Assawoman Bay Quadrangles, Delaware

The geologic history of the surficial units of the Bethany Beach and Assawoman Bay Quadrangles is that of deposition of the Beaverdam Formation and its subsequent modification by erosion and deposition related to sea-level fluctuations during the Pleistocene. The geology reflects this complex history onshore, in Indian River Bay and Assawoman Bay, and offshore in the Atlantic Ocean. Erosion during the late Pleistocene sea-level lowstand and ongoing deposition offshore and in Indian River Bay during the Holocene rise in sea level represents the latest of several cycles of erosion and deposition.

Highest point in Delaware

Ebright Azimuth - The Highest Monumented Point in Delaware

For many years, there has been a question in the minds of some Delawareans as to whether Delaware's highest elevation is Centreville or on Ebright Road. The Delaware Geological Survey (DGS) at the University of Delaware, through its relationship to the National Geodetic Survey (NGS) has determined that the highest monumented spot in Delaware is located on Ebright Road, near the Pennsylvania state line. Ebright Road is north of Namaans Road, east of route 202.

Celebrate Geologic Map Day 2012!

DGS Geologic Map 16

Friday, October 19th has been designated Geologic Map Day 2012. As an extension of the National Cooperative Geologic Mapping Program of USGS, Geologic Map Day focuses the attention of students, teachers, and the general public on the study, uses, and significance of geologic maps for education, science, business, and a variety of public policy concerns.

DGS releases new DGIR web application

Delaware Geologic Information Resource (DGIR) Web Application

The Delaware Geological Survey has released the Delaware Geologic Information Resource (DGIR), an online data display tool and map viewer for geologic and hydrologic information, as a "beta" site. DGIR was designed to provide the Delaware professional community with a variety of geoscience data in one application. DGS will continue to refine the both the data and functionality of the website as it is reviewed.
