EDS offers political information products for businesses, associations, and governmental organizations. Election Data Services has applied 39 years of experience with redistricting, elections, and GIS (geographic information systems) towards the development of a variety of political information products for businesses, associations, and governmental organizations. Current products include election returns and voting statistics, district boundary files, a ZIP+DISTRICT file linking postal ZIP Codes to district boundaries, data on voting equipment usage, contact information for state and local election officials, and an election poster with maps showing the results of November general elections for President, U.S. Senator, and U.S. Representative, governorships and state legislatures. Election Data Services has also developed GIS software — PRECIS Precinct Information System — for election officials to manage voting precincts and assign voters to precincts and districts.

PRECIS
A comprehensive, easy-to-use precinct management solution for ArcGIS (ESRI)
PRECIS® is geographic information system (GIS) that Election Data Services developed to provide election administrators with a comprehensive, easy-to-use solution for managing voting precincts and assigning voters to precincts and districts. PRECIS uses an enhanced Census TIGER base map and data from a jurisdiction’s Registered Voter File to pinpoint voters on a digital map. This allows users to see where voters reside and to monitor dynamically-updated voter counts as they use the PRECIS mapping tools to draw new precincts or to split, consolidate, or adjust the boundaries of existing precincts. A simple click of a button generates a Street Index File that can be exported to a voter registration system to update voter assignments to precincts and districts.
