Welcome to the Concord WebGIS. The Town of Concord is committed to
expanding the information made
available through this website and using our WebGIS to
provide public access to this information as economically as possible.
A Geographic Information System or "GIS" is a collection of computer hardware, software, and geographic data for capturing, managing,
analyzing, and displaying all forms of geographically referenced information.
The need for a GIS program in Concord was first documented in 1987 when the Town adopted a long range plan that included a recommendation to build a
Town-wide GIS program. After much research and planning, the process began in earnest in 1995 when the Town contracted for an aerial photography project that included
converting the existing assessor's tax maps from mylar to a digital parcel layer. During the photography project numerous layers of information were developed, called
planimetric mapping layers, which included such layers as fire hydrants, manholes, catch basins, stone walls, fences, wet areas, light poles, building footprints,
swimming pools, and paved areas. Eventually this information was all converted to GIS format.
While the photography project was underway, the Town also contracted with a firm to provide GIS consulting services. A GIS Committee, appointed by the Town Manager and
comprised of Town staff, provided project oversight and direction to the GIS Consultant. One of the first tasks undertaken by the GIS consultant was a GIS Needs Analysis
and Assessment. Members of Town departments were interviewed, with questions asked to gauge the level of GIS knowledge and to help determine which GIS tools would best
benefit the Town. “How can GIS help Town staff do what they do better and faster” became the guiding principal and the results of the analysis and assessment drove the
development of the GIS program for the next five to seven years. Another recommendation was the need for a GIS Coordinator to help manage the day-to-day program development.
During this time of GIS program development, tools were created for both public and staff use. The most popular of these were the Public Access Kiosk, which were set up in two
locations – the Town House and the Department of Planning & Land Management Office, and the Abutters program for staff use. The Kiosk program was an easy-to-use wizard-based
program that guided a person through the process of searching for properties and making a map. It allowed people to print a map at normal map scales required for submitting
information to various Town boards. The Abutters program allowed Town staff to quickly and easily create a list of abutters to a specific address, which were then used to provide
notification to residents of construction and development projects and public meetings.
The popularity of the Public Kiosks led to the development of Concord's WebGIS. The WebGIS was, and is, an Internet-based GIS mapping and property query tool open to public use.
The initial site came on-line in 2000 and quickly gained popularity, with users soon demanding more functionality. The Town entered a nation-wide contest that year and won third
place in the Geography Network Challenge sponsored by ESRI and National Geographic, against such competition as Minnesota MetroGIS, the City of Tuscon, the USDA Natural Resource
Conservation Service, and the Chicago Police Department. (For more information on this contest, click here.
In late 2001, a specialized WebGIS was developed for use by Water and Sewer Division personnel, which then led to the idea to link paper documents to GIS data on the web. Starting
with existing paper copies of recorded property plans from the Registry of Deeds, the Engineering Division scanned these documents, linked them to parcels, and then made them
available for public access on the WebGIS. At the same time, Water and Sewer service tie cards were scanned and made available to Town staff through the separate Water and Sewer
Since 2001, the program has continued to evolve. The GIS Coordinator position was created in 2000, slowly taking on programming responsibility from the GIS Committee, which was
formally dissolved in 2006. The WebGIS sites were converted to an open-source programming format (called MapsOnline) when the Town changed GIS consultants. An update of the GIS Needs Analysis was
done by the new GIS Consultant, and most of the identified projects resulting from that Analysis have now been completed (2009). There are now at least 10 different MapsOnline websites
either in use or being planned for development. Some of these are for public access, while others are specialized for staff use. The public kiosks have been updated and modernized
as well, however their use has reduced dramatically while the use of the MapsOnline sites has increased.
In 2007 a new aerial photography project was conducted. Several planimetric layers were updated at that time, and new full-color high resolution digital aerial photographs were developed.
New technology allows the Town to link Internet-based database information to MapsOnline layers on-the-fly, as the databases are updated. This is a very exciting prospect, and much of the
Town's new GIS-related development utilizes this technology. The Town of Concord is excited to be at the forefront of municipal GIS in New England, and continues to find inspiration from
those who seek geographic information in relation to the work that is being done by staff and by the residents of Concord.
In 2013 the Town's MapsOnline was updated to the latest Google-like technology resulting in full-screen mapping and faster re-draws.
