The Delaware DataMIL

Maintaining the Delaware Spatial Data Framework


• Delaware’s GIS Community• Delaware Spatial Data Framework• Delaware and The National Map• DataMIL Architecture• Map Production Laboratory• Public Participation• Future Directions


Delaware…

• No central “GIS Authority”

• Data developed at, and shared among, all levels of government

• Based on a shared Framework standard: data sets “work together”

• All contribute data, all gain data


Delaware

• 2,000 Square Miles

(Give or Take)

• 784,000 Folks

• 3 Counties

• 57 Municipalities


A Close-Knit Community

Our Challenge

• Create and maintain useful spatial data

• Accurate, up-to-date, statewide

• Open to all

• In a completely distributed environment

• With no truly formal control


Coordination, Not Control

• Local expertise creates better data

• Two keys:– Communicate– Share Data


Delaware’s GIS Community

• Inter-related Committees– State Mapping Advisory Committee– Delaware Geographic Data Committee– Delaware Spatial Data I-Team

• Focused on Delaware’s Spatial Data Framework


The Spatial Data Framework

• Accepted in 2000

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

• Limited to core, skeletal data sets

• Part of the National Spatial Data Infrastructure (NSDI)


Geographic NamesLand UseCadastralTransportationHydrographyGovernmental UnitsGeodetic ControlHypsographyOrthoimagery


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)


NSGIC, Sept. 2000, Tahoe

• Discussion With USGS

• We have data…

• …you have data

• DLG updates?


The National Map

• Seamless • Nationwide• Current• Partnership based• Major data themes• Public domain• Online accessibility


Can We Have…

• Somewhere on-line to combine and compare data?

• A collaboratory where we can host discussions?

• Mini topo maps?

• Easy-to-use interface?


• Coincidence of DataMIL and The National Map

• Past & Present Partnerships

• Tremendous Synergy and Focus

Serendipity?


What Is the DataMIL?

• Delaware Data Mapping and Integration Laboratory (DataMIL)

• Maintain and improve Delaware Framework through collaboration

• Provide access to Delaware Framework information for all


DataMIL’s Components

• Partnership-based; MOAs among State and Federal agencies

• Spatial Data and Metadata Servers

• Public Participation/Feedback Process

• Web Services

• Web Site

“Delaware was the ‘First State’ at the start of the nation; now we're ready to be the first state in the new, 21st century National Map.”

Making It Known

• Governor’s Press Release

• Newspapers, TV, Radio

• Web links

• Extensive e-mailing


Real World Uses

• It’s Shields, Not “Shilds”

• That’s not a stream, that’s a driveway.

• Selbyville Police Chief– Emergency planning– Knowing where the

ditches are


What Next?

• Mapping Partnership Office (MPO)• Cadastral Layers• Vertical Integration of Framework

Layers• Develop Delaware Framework Data

Model• Non-Framework Layers?
