WSDOT scan locations for all 3DTL projects are maintained in Transmapper with a GIS compatible layer. |
Scanned data sets can be enormous, reaching a billion points or more. WSDOT Photogrammetry uses enhanced computers and software systems to manage these massive data sets.
Photogrammetry produces standard WSDOT CAD files that can be used on regular computers used by project designers and planners.
