Claim One:
1. A method comprising: receiving, by an apparatus, a plurality of sample curvature values of a road section collected by sensors carried by vehicles traveling via the road section; applying, by the apparatus, at least one transformation function to the sample curvature values to transform the sample curvature values into one or more bin values; binning, by the apparatus, the sample curvature values into one or more respective bins based, at least in part, on the one or more continuous bin values; (1) initiating, by the apparatus, a storage or a transmission of the one or more bin values, (2) processing, by the apparatus, the one or more bin values in the respective one or more bins to determine statistical information for the respective one or more bins, or a combination thereof; initiating, by the apparatus, an inverse transformation of the statistical information, the one or more bin values, or a combination thereof back into curvature values mapping the road section; and initiating, by the apparatus, a navigation presentation on a user interface including the road section mapped based on the curvature values mapping the road section.
