CTI chooses to remain a small and flexible company to maximize interaction and synergy between ourselves and the groups we work with. The result is focused service and sensitivity to details necessary in the GIS industry. One of CTI's primary objectives is to provide custom computer programming and applications at a reasonable cost. Our programming services revolve around core GIS technology. This often makes GIS more usable and effective for the user.

CTI's principals have over twenty five years combined experience and have worked together over twelve years in the GIS and Cartography fields. CTI's broad range of experience spans both the public and private sectors.
