Geocoding Services

Description:

VCGI, in collaboration with the VT E911 Board, has created a suite of geocoding services that can be used to batch geocode addresses using ArcGIS Desktop 10.x. This service can also be integrated into ESRI ArcGIS web-based mapping applications.

Software Requirements

  • ESRI ArcGIS Desktop 10.x
  • ESRI ArcGIS API for Javascript, Flex, or Silverlight

Available Services

Service Description Server
GCS_E911_COMPOSITE_SP E911 Composite geocoder - uses ESITE, RDSNAME, and RDSRANGE maps.vcgi.org
GCS_E911_ESITE_SP E911 ESITE geocoder - address pts maps.vcgi.org
GCS_E911_RDSNAME_SP E911 road name geocoder maps.vcgi.org
GCS_E911_RDSRANGE_SP E911 road address range geocoder maps.vcgi.org

 

REST Endpoint: For use with ArcGIS-based web mapping applications

http://maps.vcgi.vermont.gov/arcgis/rest/services/EGC_services/

Input Address Requirements

  • Must use valid E911 addresses (street style addressing...no P.O. box addresses!) and E911 town names.

Limitations

  • Don't attempt to geocode more than 50000 records or so.
  • You must have an Internet connection to use the services. A DSL, cable, or other high bandwidth connection is the best option.
  • Addresses other than E911 addresses are not supported.
