When city, county, and private industry get together to help each other on a massive scale like this, we think that says a lot about what it's like to live and work in Chatham County and Savannah. Other engineers are already using the data for design work and drainage studies. According to Roach, the new ALTM data has shown that the actual flood-prone area is smaller than shown on FEMA's conventional mapping. This may open new areas to development without endangering future buildings and property. In a low-lying area like Chatham County, there are certain properties that are flooded in every major storm.
High cloud cover, most vegetation, and difficult or dangerous access are no longer a problem.
Additionally, ground activities including operations and traffic flow can continue, uninterrupted. Hundreds of acres or miles of roadway can be surveyed in minutes instead of days or weeks. Data can be processed in days instead of weeks or months. It's efficient with a cost structure that decreases as the size of the survey increases. 6-inches, it is nearly as accurate as conventional survey.
