Kroll Map Company creates and maintains Congressional District, Legislative District, Voter Precinct, and Census Tract map layers for clients throughout the United States. We integrate the latest available political and demographic boundary data with clear, professionally designed base maps at the city, county, state, and national levels. These maps provide accurate and visually effective geographic information for planning, analysis, and public communication. Because voter precinct boundaries frequently change and often require extensive GIS processing and verification, additional charges may apply for the acquisition, preparation, and maintenance of certain precinct datasets.
