a mobile device comprising a display and one or more processors; one or more memories; and a navigation application stored in the one or more memories, wherein the navigation application executed by the one or more processors:
accesses a tessellated map, the tessellated map comprising a plurality of tiles on a map of a transit hub or plaza, wherein the tiles comprise:

causes the display coupled to the one or more processors to:
indicate, using a first color, one of the first tiles including one of the different areas of interest selected using input from a user;
indicate, using a second color, one of the second tiles including a location of the mobile device on the map; and
