What is DataMIL?

DataMIL = Data Mapping and

Integration LaboratoryDeveloped from conversations between Delaware Geological Survey, Delaware Office of State Planning Coordination with USGS regarding the revision of Topographic Maps and Digital Line Graphs using Delaware data (September 2000).

DataMIL - Primary Objectives

• Combine state (Delaware) and federal (USGS) geographic data to create the most up-to-date database possible

• Allow online access for the general public, state and federal agencies in the form of digital GIS data, online images, hard-copy maps, and database attribute information

• Optimize data storage, maintenance, accessibility, and archival procedures

The State of Delaware

has no central

“GIS Authority”!

Delaware Geographic Data Committee (DGDC)

• House Bill 395, 1998 created the DGDC

• State-wide, multi-disciplinary membership

• To promote the sharing of geospatial data, information, and knowledge

• Works in Coordination with State Mapping Advisory Committee (SMAC)

• Coordination, not Control!

Delaware Spatial Data Framework

• Approved by SMAC and DGDC Summer of 2000

• The “skeleton” that holds together a wide variety of spatial data sets

• A shared Framework standard means data sets work together

• Delaware Version 1.0 complete at 1:24000 scale– Nine Layers

• Geographic Names

• Land Use• Cadastral• Transportation• Hydrography• Gov. Units• Geodetic Control• Hypsography• Orthoimagery

Need for Improvement

• Delaware topographic map series (DRGs/DLGs) produced in early 1990s

• Updated Delaware DOQQs 1997/2002, Land Use, DelDOT Transportation Network, Municipal Boundaries, Watersheds (Delaware Framework)

• Several USGS National datasets under development – GNIS, NHD, NED, Imagery, Land Cover (The National Map)

The National Map

• Seamless nationwide

• Current

• Partnership based

• Major data themes

• Public Domain

• Online Accessibility

• 9 Pilot Projects
