For Business And Industry

B Y A NDREW G OROSKO

The Housatonic Valley Economic Development Partnership (HVEDP) has provided

Newtown with a series of maps that will be useful not only to land-use

planners, but also to local businesses and industries, which are important to

the town's economic development.

Peg Daley, HVEDP director, presented the detailed maps to town technical staff

members Monday at the town land use offices in Canaan House at Fairfield

Hills. The maps will be stored there for use by the public. A state grant paid

for the mapping.

Newtown is one of six towns in the 10-town region which is receiving the maps.

The mapping system includes a base map, or general outline map, which contains

basic information about the town, such as the location of streets and bodies

of water. Overlay maps, which contain information about specific features, are

placed over the base map to add layers of cartographic detail to the base map.

The overlay maps are printed on clear plastic sheets through which the base is

visible.

One overlay, for example, contains information about the location of the

town's sewer system now under construction.

Other overlays contain information about the location of natural gas lines,

public water lines, commercial areas, industrial areas, and land contours.

By choosing the proper overlay maps, map users can view the type and level of

detail required for a particular type of land use planning.

The overlay maps are generated by a Geographical Information System (GIS) used

by the HVEDP and the Housatonic Valley Council of Elected Officials, the

region's land-use planning agency.

The HVEDP will incorporate a digitized aerial photo of the region for help in

land use planning, Ms Daley said.

Also, as the HVEDP's mapping system evolves, individual property lot lines for

some of its member towns will be added to its cartographic database.

The HVEDP also will be able to include financial information about individual

businesses which are depicted on the mapping, Ms Daley said.

"There are tremendous possibilities with all of this information," she said.

To keep the mapping system useful, it must contain updated and accurate

information, she said.

Information about the locations of known hazardous materials used by industry

could be included on the mapping to make it more useful for emergency service

workers.

"It has incredible power," Ms Daley said.

First Selectman Robert Cascella said the town has ordered the $1,200 MapInfo

Professional GIS software. The software will be used on a town computer, Mr

Cascella said.

HVCEO will provide its member towns with basic training in using the GIS

system, Ms Daley said.

The GIS can be used by every department in a municipality that stores

information which can be keyed to geographic locations.
