P18. Request GIS Mapping Information
Graphic Information System information may be useful to engineers, but it is not a widespread tool and typically is not a tool that is used by Design Engineers. The primary users of GIS. information are the District Planning Divisions, Surveys and the Environmental Divisions. Mapping from GIS does not have the accuracy needed by engineers for preparing drawings of project alternatives.
However, information from Environmental GIS databases may reveal the presence of archaeological sites, historical sites and areas of biological concern. This kind of information is important for the Engineer to consider during the development of project alternatives. GIS databases used by the Planning Divisions may provide information about land use and zoning, traffic volumes and future land development, all of which are important considerations.
Implementation of GIS tools and use of GIS data differs greatly amongst districts.
