Welcome to CJA Geographic Consulting


Carolyn_J_AndersonA GIS Certified Expert Witness, I am a degreed political scientist and geoographer with over 20 years of experience using GIS, I have worked as a GIS manager and a GIS specialist creating a wide variety of geographic or demographic products and services.  My technical experience and knowledge includes redistricting and gerrymandering.

As the GIS Specialist for a state legislature for over a decade, I provided technical support for redistricting based on 2000 and 2010 US Census population data, and was responsible for the new district maps on paper and for the web.  To see a sample, click here.http://www.capitol.tn.gov/districtmaps/HouseDist24.pdf 

In addition, I used a wide variety of data to create custom maps and tables at the request of members and legislative committees.  A few examples include geo-location of all higher education facilities, colleges and universities, community colleges, technical schools, and satellite facilities;   cigarette tax information for all states;  creation, maintenance and updating of precinct databases from all counties and associated district maps.

Another major task the acquisition and mapping of elections data.  See the adjacent map.
