Disclosed are a method and a system of a mapping search engine offering sidewalk maps, according to one embodiment. In one embodiment, a method of a sidewalk mapping server includes calculating a slope angle of a sidewalk transitioning into a street in at least one of a start location and an end location of the sidewalk in a neighborhood area and determining a transition characteristic of the sidewalk transitioning into the street. The transition characteristic is at least one of a grade-down transition, a grade-up transition, and a gradual transition in at least one of the start location and the end location of the sidewalk in the neighborhood area. A sidewalk map of a neighborhood is generated based on a calculation of the slope angle of the sidewalk transitioning into the street and a determination of the transition characteristic of the sidewalk transitioning into the street.
