Welcome!
The County’s Geographic Information Systems (GIS) effort has been ongoing since 1994. Since then the county has created a centralized County Enterprise GIS. This enterprise approach includes centralized functions such as the development and maintenance of core data layers, development of data standards, system administration, and general oversight of GIS activities county-wide.
The Enterprise GIS supports numerous County agencies with their varying GIS needs and is involved in many county-wide GIS initiatives which are as follows:
- Addressing and Road Centerline Project (internal access only)
- Pictometry (2010)
- Parcel Data Maintenance/Development
- Internet Application Development
- Planimetric Maintenance
Enterprise GIS recipient of ESRI's 2010 SAG Award
Frederick County's Enterprise GIS is the recipient of ESRI's 2010 Special Achievement in GIS (SAG) Award. SAG Awards are presented to organizations and individuals who make outstanding contributions to our global society and set new precedents throughout the GIS community.
The Enterprise GIS team was nominated for their work on the Survey Control Network Mapping Application, which went live in 2009. This application which features ArcGIS Server and Adobe FLEX technologies, was created as a tool for the surveyor community to get helpful information on the control monuments and surrounding area in Frederick County.

Map Services Published with ArcGIS Server Now Available
Enterprise GIS has several Map Services published with ArcGIS Server which are now available to the public. The Map Services menu now lists Web Mapping Applications as well as ArcGIS Server Services. On the ArcGIS Server Services page, the links for map services are provided for various clients, such as ArcGIS Javascript, Google Earth, ArcExplorer, and ArcMap.
ArcGIS Javascript links will open a browser window and display the map service using ESRI ArcGIS Javascript API. Users will need to download a current version of Google Earth 
and ArcExplorer to take advantage of the respective links. ESRI's ArcMap link provides a layer file which can be opened directly in an ArcMap product (ArcMap required) or saved locally. For more information on service types please visit the ArcGIS Server Services page. Posted on 04-14-2010

Enterprise GIS Staff Celebrates GIS Day 2009
Wednesday, November 18th marked National GIS Day for 2009, and the Enterprise GIS team celebrated during the whole week of November 16-20th. The GIS Day Proclamation by the Board of County Commissioners (BOCC) kicked off the week on Tuesday, November 17th, with GIS staff throughout the County attending. The proclamation was followed by a short GIS presentation to the BOCC and to the public by Marshall Stevenson, Strategic Systems Manager for IIT. To see this meeting, please visit Frederick County Government's media page.
On Wednesday, staff from Enterprise GIS visited Glade Elementary School, to present a geography lesson to Mr. Offutt's fourth grade class. GIS Specialist Geoff Caruso read "There's a Map on My Lap!" by Tish Rabe, while the students followed along. Afterwards, the students created a map in groups based on their Schoolyard Habitat.
The following day, additional staff from Enterprise GIS returned to Urbana High School to talk about what GIS is and what projects that the County is currently working on. They also demonstrated some of the web applications developed in-house, and introduced a new tool being utilized by the County, the Adapx Capturx Digital Pens . Students then participated in a hands-on activity with the digital pens, where they planned a Music Festival at the fairgrounds by marking on pre-made maps.
They were able to see their markups digitally after the data from the pens was loaded to a computer. To view these as well as other materials used in GIS outreach, please visit the Educational Materials page. Posted on 11-25-09
