Description: The Pavement_Marking_ArrowSymbols feature class created to manage pavement marking data for the City of Portland. This feature class contains longline street paint data for the City of Portland. Arrow symbols are pavement markings best symbolized with a point, painted by a stencil on the street. It was created to assist with paint marking updates and to improve estmation of needed paint quantities. It was created from data originally contained in a pavement marking database designed by 3m, and updated from 2015, 2017 and 2018 imagery, as well as traffic marking plans, both CAD files and georeferenced image files. The original data was created in approximately 2014, and updated in 2016 and 2019. Updates are planned to take place annually.
