1. A method comprising:
storing, by a network device, a radio map comprising map data configured to enable radio-based positioning within a geographic area, wherein the radio map is associated with a plurality of instances of quality information, and each instance of quality information of the plurality of instances of quality information corresponds to a respective location within the geographic area;
receiving, by the network device, a quality information request corresponding to a geographic region within the geographic area, the quality information request associated with an entity;
based on a determination of whether a contribution by the entity to a portion of the map data that corresponds to the geographic region satisfies one or more significance criteria, providing or withholding quality information corresponding to the geographic region;
determining that the contribution provided by the entity to the portion of the map data corresponding to each of a first number of geographic regions with the geographic area satisfies the one or more significance criteria;
determining that the first number of geographic regions is greater than a threshold quantity of geographic regions; and
determining a set of regions selected from the geographic regions for which the contributions provided by the entity to the portion of the map data satisfies the one or more significance criteria, the set of regions contains a second number of geographic regions, the second number of geographic regions being at most a threshold quantity of geographic regions,
wherein providing the one or more instances of quality information comprises providing instances of quality information only corresponding to respective locations located within geographic regions included in the set of regions.
