Data Update: Delaware Municipal Boundaries

Friday, March 25th, 2011 by mike.mahaffie

The statewide municipal boundaries dataset has been updated by the Office of State Planning Coordination. This update is not to the geometry of the various boundaries, though those updates do occur on a regular basis. This update is to the layout of the file and the attributes that are included.


Now Available: NHD Training WebEx

Slide from NHD presentationThe introduction to the National Hydrography Dataset (NHD) that was offered by the USGS and NSGIC yesterday is now available on-line. The training was presented by Jeff Simley, of the USGS, and included an overview of the NHD, plans to make it even better, and a discussion of the state/federal partnerships that have made the project possible.

The National States Geographic Information Council (NSGIC) plans a “virtual conference” session, via WebEx webcast, on the National Hydrography Dataset (NHD) on Tuesday, April 27. We will offer two viewing opportunities for this webcast: one in Dover and one in Newark.


Noted: A National Effort on Transportation Data

Thursday, April 8th, 2010 by mike.mahaffie

The US Department of Transportation (US DOT) and National States Geographic Information Council (NSGIC) have announced a strategic planning effort aimed at creating a national — read that as local, county, state and federal rather than just federal government — transportation data set. This is an attempt to make real the goals of what NSGIC calls Transportation for the Nation (TFTN): “to coordinate and develop nationally significant geospatial transportation data, with particular emphasis on road centerlines.”

The strategic planning effort will include workshops and needs-requirements gathering at national conferences and other opportunities to meet with data-users. It will be managed by the USDOT GIO. The contractors working on the project are Koniag Technology Solutions, Inc. and Applied Geographics, Inc. Applied Geographics is also helping create the Delaware GIS Strategic Plan).

A Useful Explanation of Delaware’s Boundary Monuments

Thursday, February 18th, 2010 by mike.mahaffie

Photo of a Delaware boundary monumentThe News Journal newspaper featured a “Did You Know” infographic on the Mason-Dixon Line (PDF) yesterday. The “Did You Know” series is not usually posted on the News Journal web site; they are designed for print and don’t translate well to HTML. (There is also a brief version, with just the text and a few pictures, up in HTML)

The News Journal was kind enough to provide us with a PDF image because of our interest in the Delaware boundary monuments.

After all, as I delight in reminding my GIS coordination colleagues from other states, Delaware is the First State and the boundary monuments are part of our very accurate state boundary data set. It can be argued, therefore, that every other state boundary in the continental United States is dependent on and derived from the Delaware boundary, and its monuments. They probably aren’t, but it’s fun to argue the point.

DGDC Executive Council Discusses GIS Strategic Plan and Possible New Orthos

Friday, December 18th, 2009 by mike.mahaffie

The Executive Council of the Delaware Geographic Data Committee (DGDC) met on Thursday, December 17, 2009, and discussed a preliminary draft outline of the Delaware GIS Strategic Plan now under development by the DGDC. The Council also voted to move forward with a possible 2011 update of orthophotography for parts of Delaware.


A Quick Look at State GIS Coordination

Tuesday, December 15th, 2009 by mike.mahaffie

Michael Terner, the Applied Geographics consultant who is working with the DGDC on a strategic plan for GIS coordination in Delaware, spoke a bit about what he’s learned in Delaware at a recent Ignite Spatial event in Boston.


DataMIL Update

Wednesday, October 28th, 2009 by mike.mahaffie

Delaware Data Mapping and Integration LaboratoryThe Delaware DataMIL has been updated with new version of the municipal boundaries data as well as with updated county “community” data, which are used to show place names for subdivisions and other areas.

All of these layers have been updated in the MapLab, the DE_Featureservice map service, and the data download section as well as the map service that feeds the Delaware portion of the national map for the federal government’s geospatial Onestop (GOS) service.

The updated datas ets are current as of October 2009.

Framework Data Discussion: “Out of Play”

Monday, October 26th, 2009 by mike.mahaffie

One item that came up in the October 20 Delaware GIS Strategic Planning Workshop (notes [PDF]) was that of adding “out of play” lands to the Delaware Spatial Data Framework. This refers to lands that are not developable, from a regulatory standpoint, such as publicly-owned lands and lands, such as tidal wetlands, that are simply out of bounds.
