What is GIS?

Geographic Information Systems (GIS) at its simplest level, is the power of where.

It’s a high-tech mapping software used as a vessel to acquire, analyze, manage, maintain, monitor, and visualize geographic data.

Imagine the idea of a “smart” map. One that can answer questions related to a precise location, uncovering more detailed information; one that can enhance communication, provide support for better decision making, improve workflow and productivity, just to name a few. That’s GIS power at your fingertips!

Leslie D. Alderman, Jr., Managing Partner, Florida Panther Conservation, LLC

"Florida Panther Conservation, LLC’s Habitat Conservation Bank was the first bank to be Approved and Certified by the U.S. Fish and Wildlife Service in Florida and the first in the Nation for the Florida panther. Approval of our bank would not have been possible without the knowledge and reputation earned by the professionals at Passarella & Associates. As our lead consultant, they were always “ahead of the curve” in anticipating the needs and demands of the Fish and Wildlife Service at the State, Regional and National levels. Passarella’s project management skills are exceptional. Because of their expertise, we were able to bring this “first time” project in on time and budget."
