1. A computer-implemented method comprising:

  • at one or more servers;

    receiving, from an electronic device, a request for a vector map sub-tile;

    identifying a vector map tile corresponding to the requested vector map sub-tile;

    accessing the vector map tile;

    generating the requested vector map sub-tile by dividing the vector map tile into a plurality of vector map sub-tiles, the plurality of vector map sub-tiles comprising the requested vector map sub-tile, wherein the vector map tile comprises one or more of a point map feature, line map feature, polygon map feature, or a three-dimensional (3D) polygon map feature, and dividing the vector map tile into the plurality of vector map sub-tiles comprises selecting one of a plurality of processes for dividing the vector map tile depending upon the map feature within the vector map tile; and

    transmitting the requested vector map sub-tile to the electronic device.
