1. A method, implemented by a computing system, the method comprising:
building a database of feature sets, each feature set being associated with, and describing characteristics of, a respective indoor location within an indoor space;
generating an address for each of the indoor locations from the feature set associated with the indoor location in the database;
searching the database using a user-specified feature set to identify an indoor location of potential interest to the user;
identifying a further indoor location of potential interest to the user that has a same address as the identified indoor location;
prompting the user to select between the identified indoor location of interest and the identified further indoor location of interest;
labeling the selected indoor location on a map using a feature extracted from the generated address of the identified indoor location; and
providing navigation instructions from a location of the user to the selected indoor location.
