AHS provides innovative geospatial services for our clients, specializing in a range of geographical and information system (GIS) applications to Cultural Resource Management (CRM) services. These GIS services are integral to each phase of archaeological and architectural projects, moving from research and planning phases to excavation, analysis, and final graphic products. Regular services include data collection, database creation, digital conversion of data, archaeological sensitivity modeling, and advanced spatial and statistical analyses. Our field crews are equipped with a Trimble GPS unit, and regularly use a Topcon total station, when increased precision is required. Exceptional cartographic products are produced in close consultation with clients, including brochures, posters, and final reports. 

Featured Project

Harbor Brook Flood Control and Walking Trail

There were two major goals at this project in Meriden, Connecticut: to identify and mitigate potential flood damage along portions of the Harbor Brook, and to establish a walking trail alongside the brook. The project had the potential to impact undocumented archaeological sites. In order to mitigate these impacts, AHS identified areas of archaeological sensitivity in a Phase IA Archaeological Assessment Survey and completed a Phase IB Archaeological Reconnaissance Survey in which sites were identified. Six archaeological sites were identified within the project area. GIS was used in every phase of this project, to streamline the archaeological assessment process along the four-mile-long project area, and to assist in data analysis and presentation.


Other Project Examples

Norwalk Bridge Replacement

AHS staff georectified historical and modern maps, highlighting areas of archaeological sensitivity, identifying the location of a Contact-period Native American fort site.


Route 11 Extension Project

AHS staff used GPS and total station technology to document 86 archaeological sites during a Phase IB Archaeological Reconnaissance Survey of an eight-mile-long corridor, including five parallel alternative paths of this extension.
