Geocoding is increasingly being used for public health surveillance and spatial epidemiology studies. Using both methods and combining the results can maximise match rates and save the time needed for manual geocoding.Ī multifaceted comparison of ArcGIS and MapMarker for automated geocoding. However, the positional differences found were minimal, and a large majority of addresses were placed on the same locations by both geocoding packages. In addition, the composite address locator in ArcGIS allows users to fully utilise available reference data, which consequently results in better geocoding results.

Among addresses with a distance of greater than 100 m between the geocodes assigned by the two packages, the point assigned by ArcGIS was closer to the associated parcel centroid (“true” location compared with that assigned by MapMarker. High similarity between the geocodes assigned by the two methods was found, especially in suburban and urban areas. Of the 551,798 input addresses, 318,302 (57.7% were geocoded by MapMarker and 420,813 (76.3% by the ArcGIS composite address locator. The comparison was based on three metrics of evaluation: completeness (or match rate, geocode similarity and positional accuracy. We evaluated two commonly used geocoding software packages, ArcGIS and MapMarker, for automated geocoding of a large number of residential addresses from health administrative data in New York State, USA to better understand their features, performance and limitations. Public health departments in the United States of America (USA often use this approach to investigate disease outbreaks and clusters or assign health records to appropriate geographic units. The borders of classes of intervals are set in depend on existing normative of pollution in different components of environment and empirical character of study parameter distribution on territory under consideration.Ī multifaceted comparison of ArcGIS and MapMarker for automated geocodingįull Text Available Geocoding is increasingly being used for public health surveillance and spatial epidemiology studies. The most optimal amount of classification intervals describing the natural processes and the phenomena of all-over distribution on the geoeclogical GIS maps is the 3–5 intervals of the parameter that will be considered. The input data were presented by the coordinates of points located on territory according to the scheme of measurements.

The geostatistic and deterministic approaches were applied for interpolation of input data. The technique of GIS ArcGIS mapping is illustrated by examples of GIS maps of radioactive and chemical pollution in the snow cover on the territory of St.
