Abstract: During operation, a computer system may provide instructions to access points in an indoor environment to measure relative distances between the access points. Then, the computer system may receive the measured relative distances. Moreover, the computer system may calculate geographic locations of the access points based at least in part on the measured relative distances. Next, the computer system may select potential anchor access points in the access points, and may provide, to an electronic device, information specifying the potential anchor access points. Furthermore, the computer system may receive, from the electronic device, second information specifying anchor access points in the potential access points and defined locations of the anchor access points. Additionally, the computer system may update the geographic locations based at least in part on the defined of the anchor access points, and may provide, to the access points, the updated geographic locations.
