GIS Division Wins Two National Awards

The National Association of Counties (NACO) announced that the Delaware County GIS Department has won two National Achievement Awards for its IMS Interactive Map Server and Sex Offender Locator Applications.

NACo’s Achievement Award is a non-competitive program that recognizes counties for creative and innovative program development and implementation, efficient administrative management of county agencies and responsible government to local citizens. Since the program’s inception, NACo has honored hundreds of county government initiatives that have generated professional well trained workforces, maintained cost effective measures, and enhanced services to diverse populations to improve the overall quality of life. Awards are given in more than 20 categories, ranging from arts and historic preservation to volunteerism.

Zoning and Development Information

In June 2007, 21 data layers were added to IMS Web application under a new tab called the "Zoning" tab. The Zoning tab provides 19 zoning layers and two "Development in Pipeline" layers for Pending Rezoning proposals and Active Subdivisions (unrecorded). 18 of these zoning layers and the two "Development in Pipeline" layers are developed by Delaware County Regional Planning Commission. More detailed metadata is available at the layer level directly from the IMS application. The City of Delaware Zoning layer is developed by The City of Delaware Development Department. To access all the Zoning layers, go to the Zoning tab of IMS Web application.

Delaware County Annexation Application

After several months of research, data collection, and application development the GIS team has launched Delaware County’s Annexation Application. Annexations and Conforming (Coterminous) Boundary proposals from as far back as 1853 to present time can now be searched either by the municipality name or by the year that the annexation was recorded. When searching, you can also use a combination of these two variables. As part of this project, every available Annexation and Conforming Boundary document was scanned and PDF versions of these scanned documents were linked to areas that the annexation and/or the conforming boundary was located in. Over 7,400 pages of scanned documents are now accessible from this application. You can also view our continuously updated parcels and road centerline layers as well as the 2006 Orthophoto imagery from this application. The application can be accessed from here.

County's Orthophoto and LiDAR Project awarded to Merrick & Company

County's 2006 Orthophoto and Light Detection And Ranging (LiDAR) project was awarded to Merrick and Company. This was the third time that Merrick was hired by the county. Merrick flew the county in April 2006 and this time, the resolution of orthophotos for the entire county was at six inch pixel resolution as opposed to three varying resolutions of six inch, one foot and two feet in previous projects (1991, 1997 and 2002). Merrick is also providing the county with LiDAR datasets and 2 foot contours for the entire county. Both the orthophotos as well as LiDAR and contour datasets will be delivered to the county by February 2007.

GIS Division's ArcIMS Application is Featured on Geography Network

The GIS team's website is featured on the Geography Network. Geography Network is a global network of geographic information users and providers. It is managed by Environmental Systems Research Institute (ESRI) and provides the infrastructure needed to support the sharing of geographic information among data providers, service providers, and users around the world.
