Patent attributes
Generating elevation data for maps is disclosed, including: selecting a barometric data candidate user activity from a plurality of user activities that matches an edge; normalizing a recorded elevation corresponding to each of at least a subset of a plurality of data points associated with the selected barometric data candidate user activity based at least in part on obtained elevation data associated with the edge; storing the normalized recorded elevation corresponding to each of the at least subset of the plurality of data points associated with the barometric data candidate user activity as a set of elevation data associated with the edge in a user preference map; and using the set of elevation data associated with the edge in the user preference map to determine a suggested route based at least in part on a user input route preference associated with a desired route elevation.
