9. A system for modifying a map, comprising: a processor; and a memory in communication with the processor and configured to store one or more programs to be executed by the processor, the one or more programs comprising instructions for: searching 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 the data element for geocode information specifying a geographic location of the data element; determining 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 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 initiate modification of the map to include a reference to the data element, wherein the reference is placed on the map at a location corresponding to the data element; and storing the modified map including the reference to the data element.
14. The system of claim 9 , wherein the instructions further comprise: filtering the apparent geo-annotations and eliminating non-geographical annotations.
