1. A method comprising:

  • receiving map data and one or more selected linear element indications, wherein the map data comprises a list of map elements;

    extracting, by a processor, map elements within a bounding box;

    indexing, by the processor, the extracted map elements, wherein the indexing comprises spatial indexing;

    searching the spatial index for map elements within a predetermined distance from the one or more selected linear elements;

    generating a composite indexable linear data structure based on the correlation of map elements with the one or more selected linear elements; and

    using the composite indexable linear data structure, providing for presentation of a map rendering, wherein the map elements corresponding to the composite indexable linear data structure are visually distinguished and enhanced with one or more of building footprint data or three-dimensional building mesh data.
