1. A method for exposing hidden landmarks of locations for treatment in an anatomical map, comprising:
receiving or generating a volume map of at least a portion of a cavity of an organ of a body comprising a plurality of mapped locations, and a point cloud of locations in the cavity marked for treatment;
updating the volume map by removing a portion of the mapped locations, so that the locations marked for treatment fall on a surface of the volume map, wherein removing the portion of the mapped locations comprises projecting the locations marked for treatment to respective locations on the surface of the volume map, and removing the portion of the volume map that comprises a surface connecting the locations marked for treatment with the projected locations;
using the updated volume map, generating a map of at least a portion of the cavity, comprising the locations marked for treatment; and
displaying the map to a user.
