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.

Morphology and Tidal Inundation of Tidal Wetlands in the Delaware Estuary

An expanse of tidal wetlands fringes the Delaware Estuary and provides Delaware, Pennsylvania, and New Jersey with abundant ecosystem services including habitat for indigenous and migrating plants and wildlife, biogeochemical cycling of nutrients, preserving water quality, flood hazard mitigation

Creation of Improved Accuracy LiDAR-Based Digital Elevation Models for the St. Jones River and Blackbird Creek Watersheds

Project Contact(s)
In tidal wetlands, the high density of vegetation cover inhibits penetration of LiDAR pulses through the vegetation to the ground surface and low vegetation heights inhibit classification of ground point elevations. This project identities and corrects for biases found in the St. Jones and Blackbird Reserves using GPS RTK surveying and statistical analysis.
