1. A method of modifying a map, comprising: searching, using a processor, a data element for user generated text that includes one or more apparent textual geo-annotations associated with the data element and input by a user indicating a location of interest; searching, by the processor, the data element for geocode information specifying a geographic location of the data element; determining, by the processor, a location proximity of (i) a geographic location for each of the one or more apparent geo-annotations to (ii) the geographic location of the geocode information of the data element; calculating, using the processor, a level-of-detail score for the data element based on the apparent geo-annotations in the user generated text and the location proximity of (i) the geographic location for each of the one or more apparent geo-annotations to (ii) the geographic location of the geocode information of the data element, wherein the level-of-detail score is a score corresponding to a geographic level of detail associated with the data element; determining that the score exceeds a threshold level-of-detail score, and in response, modifying the map to include a reference to the data element, wherein the reference is placed on a the map at a location corresponding to the data element; and storing the modified map including the reference to the data element in a memory device for subsequent presentation.
