  • Creating maps and statistical data from the database layers;
  • Using spatial models to perform analyses on real world problems;
  • Supporting city staff in their efforts to use GIS application programs;
  • Assisting city staff with GIS and mapping needs for special projects; and
  • Providing the public with self-serve web maps and open data
