Surveying & Mapping
Important FPRN Update Information: Currently we are in the process of upgrading the FPRN to a newer version of Spidernet software. This will be done in stages. We will have a new IP address (184.108.40.206) to be used for the connection to the network. Whether you are already registered with FPRN or not you will be required to register/re-register with the new database to be able to use the new system. Please note that the new network ZONE boundaries are coincident with the FDOT District boundaries. To minimize the number of Mount Points in a given Mount/Source Table select the zone that includes your location.

positioning activities throughout Florida and surrounding states.
