Line feature along sidewalks and walkways from 2020 planimetric set. These five towns were scrutinized on a large scale basis in February of 2023. Sidewalks were chosen to be defined as walks along the side of a road. Walkways anre walks that are in peoples' yards or business' property. They may be distinguished by using the attribute named "walkway" which is Yes for a walkway, No for a sidewalk.
Additionally, data were missing in North Chatham in the 2020 feature. This was corrected in the feature named "sidewalk_GP_Merge", which merged the two features "sidewalk_GP" and "SidewalkLine_z_missing_Chatham" which had the data collected during the 2014 planimetric project. For these features the attribute named "status" will equal "Old". The data in this feature will eventually be merged back with the other towns of Cape Cod.
