Abstract: In a computer system, a pedestrian dataset that indicates position fixes for several portable devices is received, such that each portable device corresponds to a respective pedestrian. Raw heat scores for several geographic units of equal size are generated based on the pedestrian dataset, each raw heat score being indicative of a number of position fixes in the corresponding geographic unit. A selection of a geographic area that contains some of the geographic units is received, and normalized heat scores for these geographic units are generated based on at least some of the generated raw heat scores.

Abstract: A process for determining and labeling areas of interest, including steps for receiving a plurality of data points from a plurality of users, each data point received at a particular time, determining a user location for each of the plurality of data points and generating a heat map from the plurality of data points, wherein the heat map represents a population density distribution over a geographic area divided into a plurality of cells. In certain aspects, the process further includes steps for identifying at least one cluster of cells within the geographic, generating a bounded polygon for the at least one cluster of cells and storing the at least one cluster of cells and its corresponding bounded polygon as an area of interest in a geographical information system. Systems and machine-readable media are also provided.
