Mapability is a crowd-sourced social venture creating overlays to online maps plus metrics that provide accessibility and livability data for cities. Mapability maps helps end users find the most accessible paths for wheelchair access, mothers with strollers, elderly, kid-safe areas, baby-care facilities, and much more. The crowd-sourced data-acquisition comes from the members of multiple active volunteer communities and other individuals who contribute by uploading geo-localized photos and accessibility parameters using a simple UI app. Online maps are free for citizens. Economic sustainability is reached by selling dedicated services that allow municipalities, urban planners, and real estate professionals to improve, create, or find the most “livable” areas based on proximity data, statistics, and user feedback.
