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.

David Wunsch, appointed to Federal Advisory Committee for the National Cooperative Geologic Mapping Program

David Wunsch, director of the Delaware Geological Survey and state geologist, has had an appointment to the Federal Advisory Committee for the National Cooperative Geologic Mapping Program approved by the White House. The committee is charged with advising the director of the U.S. Geological Survey on planning and implementation of the geologic mapping program.

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.

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.

United States Geoscience Information Network (USGIN)

United States Geoscience Information Network (USGIN)
Project Contact(s):

The United States Geoscience Information Network (USGIN) initiative is the product of a partnership between the Association of American State Geologists (AASG) and the United States Geological Survey (USGS) created to facilitate discovery of, and access to, geoscience information provided by state and federal geological surveys of the United States. DGS has entered into a partnership with the Arizona Geological Survey (AZGS) to participate in USGIN by establishing a metadata clearinghouse node for Delaware.

Mapping Tsunami Inundation for the U.S. East Coast

National Tsunami Hazard Mitigation Program
Project Contact(s):

This project will assess tsunami hazard from the above mentioned and other relevant tsunami sources recently studied in the literature and model the corresponding tsunami inundation in affected US East coast communities. We will combine ocean scale simulations of transoceanic tsunami sources, such as Lisbon 1755 like or Puerto Rico Trench co-seismic events, and CVV collapse, with regional scale simulations of these events, along with the regional scale SMF events, in order to establish the relative degree of hazards for East Coast communities. Detailed inundation studies will be conducted for highest-risk East Coast communities, and results of these studies will be used to construct a first-generation of tsunami inundation maps for the chosen communities.

DGS Geologic Map No. 17 (Harbeson quadrangle) Dataset

DGS Geologic Map No. 17  (Harbeson quadrangle) 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. 17 (Harbeson quadrangle). The complex geologic history of the surficial units of the Harbeson Quadrangle 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 is further complicated by periglacial activity that produced dune deposits and Carolina Bays scattered throughout the map area.

First State Geology newsletter available online

In support of the University of Delaware's sustainability efforts, the Delaware Geological Survey is offering its First State Geology newsletter as an online document.

First State Geology features news about Delaware geology and water resources, recent DGS publications, and DGS staff activities.

DGS releases new geologic map of Rehoboth Beach area

The Delaware Geological Survey (DGS) has published a new geologic map of the Rehoboth Beach area in eastern Sussex County entitled Geologic Map of the Fairmount and Rehoboth Beach Quadrangles, Delaware. Geologic Map 16 presents the results of research by Kelvin W. Ramsey of the DGS.

Delaware Geologic Mapping Program (STATEMAP)

STATEMAP Status Map

The Delaware Geological Survey has a continuing program to map the geology of the entire state at the detailed scale of 1:24,000. The STATEMAP component of the National Cooperative Geologic Mapping Program has contributed significantly to our surficial geologic mapping program. This work has resulted in not only new geologic mapping, but also the digital compilation of previous mapping. Products of this program include file formats that can be downloaded and printed from the web as geologic map products and imported into GIS software as georeferenced layers.
