Sidewalk and Trail Centerlines are collected as a base map data layer derived by automated processes and processed for cartographic representation at 1:2400 scale. Typical features captured in the Sidewalk and Trail layer include are sidewalks, trails, shared use paths, golf cart paths, crosswalks and the W&OD trail features as seen from above and are mapped to National Map Accuracy Standards (NMAS). Supplemental data, including connectors and crosswalks, are captured from visual inspection and digitization from the County's digital aerial imagery.Prior to 2020, Sidewalk and Trail Centerlines were a layer derived from the base map data layer Miscarc_line.
