1. A method for providing a smooth map view, the method comprising:
requesting, by a device, map data for a geographic feature;
receiving, by the device from a mapping server, one or more spline identifiers and spline attributes related to the geographic feature, wherein one or more spline functions that relate to the one or more spline identifiers are stored on at the device;
rendering, by the device, a first representation of the geographic feature by applying at least one spline function of the one or more spline functions and related spline attributes to generate a plurality of coordinates values that when connected comprise the first representation, wherein the plurality of coordinate values are generated to at least a 10th decimal place; and
displaying, by the device, the first representation.
