The dataset contains pedestrian-level sidewalk images collected in Seoul, Republic of Korea, together with ground-truth accessibility attributes: field-measured sidewalk width, longitudinal slope, and cross slope, and pavement condition grades assigned by three independent raters and resolved by majority vote. Dataset contents The dataset includes ground-truth annotations for: Sidewalk width Longitudinal slope Cross slope Pavement condition Ground-truth attributes are stored in the csv file summary_attributes.csv where the filename column gives the corresponding image file name in imagery.zip.
