The final report for NCHRP 25-25, Task 90, Application of Geographic Information Systems (GIS) for Historic Properties is available HERE.

Presentation slides with speaker notes are available HERE.

Literature pertaining to the application of GIS to identify historic properties exists; however, no summary or evaluation of these applications has been undertaken to quantify the benefits of using GIS. This research provides a nationwide survey of the roles GIS has played in saving taxpayer dollars and streamlining Section 106 compliance on federally funded transportation projects.  The results provide transportation agencies with guidance for the use of GIS to identify and manage historic properties efficiently and effectively.
