Metre by metre, researchers are mapping the city using a geographic information system.

The collected data were analyzed using a geographic information system (GIS).

A database of litter black spots is being created using geographic information system (GIS).

Annual clinical measures were linked to metrics from a geographic information system for each patient's address of longest residence.

We describe a geographic information system-based method for calculating age-standardized cancer incidence rates in non-census defined geographical areas using publicly available data.

We calculated the Euclidian distances between each participant's residential address and the nearest green space or senior service center, using a geographic information system.

Air pollution exposures were assigned to each residential address in 2000-06 using a geographic information system that included monitoring data.

The geographic locations of five F29 strain clusters were plotted using a geographic information system (GIS) and an index for geographic distribution was calculated.

The re-creation relied on old maps, soil cores, and other information which was fed into a geographic information system (GIS) database developed for the project.

Methods: This case-control study uses a geographic information system-based exposure assessment tool to estimate ambient exposure to 36 commonly used OPs from 1974 to 1999.

The MTI data were fit and aggregated to the 270 meter x 270 meter grid cells used in field-based sampling using a geographic information system.

Geographic information systems provide opportunities to contribute valuable methodologies to study these relationships.

Concurrently, sociometric surveys were conducted, and households were mapped with geographic information systems.

We also used both geographic information systems and geostatistics to identify spatial clusters of cases.

Fast-food restaurant exposure within 500 m of the participants' residence was determined by using a Geographic Information System.

The group includes computer science PhD candidates, mathematicians, political operatives, and experts in so-called geographic information systems, or GIS.
