Abstract
A method, product and system for three dimensional map generation based on crowdsourced positioning readings. The method comprising obtaining a plurality of positioning readings of a plurality of mobile devices. Each reading of the plurality of positioning readings is indicative of an altitude, latitude and longitude of a mobile device, and is determined using one or more sensors of the mobile device. The method comprises clustering the plurality of positioning readings to determine clusters of positioning readings. for each cluster, an altitude value is computed, based on an altitude of each positioning reading in the cluster, whereby determining an estimated altitude based on non-accurate altitude readings. The three-dimensional map is generated based on the plurality of positioning readings and the altitude value of each cluster.
