Geographic Information System

GIS is an informational system capable of integrating, storing, analyzing and managing data which are spatially referenced to Earth.  The WVDOT utilizes GIS for planning, analysis, and mapping.  In addition, GIS is being established as an enterprise system capable of integrating and spatially enabling various legacy databases throughout the WVDOT.  The key component to make this happen is based on the WVDOT Linear Referencing System.  This simply put is the milepost along side of the roads; this has been the traditional method of locating asset or incident on roads.  By integrating this information into our GIS, we are able to establish an enterprise system (See diagram below).
