The Delaware DataMIL is Retired

Date

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.

Welcome to Geologic Map Day, a special event designed to promote awareness of geologic mapping and its vital importance to society.

Strategic Plan for Geologic Mapping of Delaware 2016-2030

Geologic maps at the DGS are created as primary deliverables of a project and as derivatives of other projects. Primary deliverables are mainly those that are the result of outside funding sources such as the AASG-USGS cooperative StateMap. Derivative maps are those that have primary data collected for reasons other than geologic mapping can be used to create geologic maps or that geologic maps are derivative products of a project rather than the primary goal of a project.

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

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).
