Each data layer may be easily updated by its owner but is protected from inadvertent change or deletion while in the hands of a casual user. The data are more available while at the same time more protected than ever before. One of the most important and often overlooked aspects of keeping a system running is the documentation of the database as well as system administration procedures. The GIS Data Dictionary provides complete documentation on all datasets housed in the central map library. A layer bibliography and a detailed description of each individual data layer comprise the bulk of the document.
System documentation is thorough as well.
Subsequent to each hardware and software upgrade, system administration procedures are checked and updated as required. System documentation also includes daily operational procedures such as the methods to monitor print queues and system processes, problem resolution logs, backup and restore logs, and system guidelines such as adding and removing users or equipment to the network. Data are also collected and maintained to monitor the system for bottlenecks and to support capacity planning. Many federal, state, and local agencies as well as private sector parties seek data from Volusia County. A number of partnerships have been developed whereby data have been freely exchanged among agencies.
