The MDC develops its landbase data through the process of photogrammetry. This process, the ability to obtain reliable map measurements by means of aerial photography, was introduced during World War II. When photogrammetry became available for civilian use, the MDC was one of the first mapping agencies in the country to adopt it.
In the mid 1980's, the MDC, seeing that mapping would eventually rely on computers, began to obtain its photogrammetric mapping data both in hard copy and in a digital, computer-readable format. The MDC began investigating the use of a geographic information system (GIS) in 1986. We acquired our first two GIS workstations and software in 1988. By 1989, the GIS unit began converting or "loading" the information from digital photogrammetry to eventually cover our existing 570 large-scale topographic maps. This involves compiling land, property and utility infrastructure information for each acre in the MDC's 156 square miles. Since then building, editing and maintaining the GIS database has been a valuable and continual process. We now have digital data covering all of our member towns and are working on building the database further to include MDC lands throughout our watershed. The GIS/Mapping activity has multiple workstations and servers, plotters, printers and scanners and a staff of eight. This comprehensive and mature system is in demand as a facilities management tool and is used to create and print out municipal street maps, utility maps and other map products
In 1994, with the help from a grant from the State of Connecticut, the MDC distributed hardware, software, digital municipal data and digital orthophotos files to each of its member towns. GIS software training was provided to selected municipal staff too. In this way, MDC member towns could utilize MDC data locally and begin development of other layers of data of local interest for applications in property assessment, police and fire safety services, bus routing, public works and more. MDC and town staffs have jointly formed a Users' Group. The group meets to share and exchange ideas, information and goals regarding the implementation of GIS in the District.
The MDC GIS has also been linked to the District's business management software. This allows staff to locate a piece of equipment, such as a hydrant or piece of pipe, select it on the computer screen using a GIS generated map and then immediately open a work order or some other business management tool, directly through that map on their screen.
The MDC also supports the Connecticut GIS User to User Network. This Network is a voluntary state-wide association of individuals and organizations that use GIS-based technologies and data in their day-to-day operations. The Network's purpose is to connect users through workshops, meetings and the Internet to share ideas, to learn about GIS activities, to explore collaborative opportunities and to discover information resources - all of which will promote a dynamic and innovative community of Connecticut GIS users. – less – More from ZoomInfo »
