Integrating Monroe County Through Community GIS
The Geographic Information System (GIS) Services Division manages Monroe County’s interagency GIS program. The GIS Services Division provides leadership, coordination, infrastructure, education and a variety of services to realize the full potential of a Community GIS. The mission of the GIS Services Division is to develop a fully integrated GIS that will support the needs of all Monroe County Departments, the City of Rochester, and local towns and villages. The division fosters countywide access to current, accurate spatial information and the elimination of duplication of effort.
Monroe County started the investment in GIS about ten years ago when the Department of Planning and Community Development began mapping environmental features, the Environmental Services Department mapped sewers, and the Office of Real Property Tax Service (Finance) learned the benefits of a GIS for the maintenance of tax parcels. In January of 2000, many of the County’s GIS functions where consolidated with the formal creation of the GIS Services Division. The division was formed to promote and educate County departments, towns and villages on GIS and to plan and implement its use throughout Monroe County.
GIS Services is one of five divisions (along with Pure Waters, Solid Waste, Engineering, Fleet Maintenance) comprising the Monroe County Department of Environmental Services (DES). “Considering DES’s role in managing sewers and fiber, while at the same time being aware of GIS’s potential role in facilities management, makes organizing GIS as a part of Environmental Services just common sense.” said DES Director John Graham.

Global Positioning System (GPS)
Over the past several years, the Department of Environmental Services has put into place a state-of-the-art GPS program.
We maintain the Continuously Operating Reference Station (CORS) for the Greater Rochester area. We are also part of the National CORS network, a cooperative network run by the National Geodetic Survey.
Our CORS station continuously records a highly accurate GPS signal at a surveyed location. The data are monitored by NGS 24 hours a day, 7 days a week, to ensure that our data are of the highest possible quality. The data is available to the public free of charge via the Internet at http://www.ngs.noaa.gov/CORS/ (our station code is NYMC).
By maintaining a continually operating reference station, we make it possible for the public to use post-processing or differential correction to greatly enhance the accuracy of their GPS data.
In addition to our base station, we have made a significant investment in field equipment. We currently operate:
- 1 Trimble 5700 Base Station, with a cellular modem link to our 5700 rover.
- 1 Trimble 5700 Real-Time Kinematic Rover. This is a survey-grade receiver that is capable of field accuracies of less than one centimeter.
- 2 Trimble ProXR Backpack Receivers. These are mapping-grade receivers that are capable of field accuracies of less than one meter.
- 2 Trimble GeoExplorer 3 Handheld Receivers. These are lightweight hand-held units that are capable of field accuracies of less than two meters, or post-processed accuracies of less than one meter.
We use the quipment for a variety of projects, including sewer asset location collection, sewer installations, cut and fill projects, land surveying, and the preservation of the Monroe County Geodetic Survey Datum.
Our equipment is available on short-term loan to other municipalities within Monroe County.

Records Room
The Department of Environmental Services Records Room staff are responsible for the collection, maintenance, archiving and warehousing of over 50,000 documents, both on paper/mylar and in digital form. We are currently in the process of scanning our physical documents into a digital document management system.
Following are some of the types of documents for which we are responsible:
- As-built drawings and sewer plans dating back to 1876
- Greater Rochester International Airport plans
- Sewage treatment plant plans
- Monroe Community Hospital plans
- Monroe Community College plans
- Hall Of Justice plans
- Right-of-Way mapping and survey information
- Department of Transportation highway and bridge plans
- Maps and plans of county parks and Seneca Park Zoo
- Topographic and Land Use Maps
- Hard-copies of aerial photography from the 1960s
We are happy to assist both local governments and the public with researching information. For a nominal fee, we can provide copies of documents on paper, mylar, or CD-ROM.
The Records Room is located on the 7th floor of CityPlace, 50 West Main Street, Rochester, NY.
We are open from 8:00 a.m. until 4:00 p.m. (Monday through Friday).
