1. A method for mapping a parking garage, comprising:
receiving, by one or more processors, floor layout data for at least a first floor of a parking garage;
based on the received floor layout data for at least a first floor of a parking garage, detecting, by the one or more processors, at least one additional floor layout data for a floor of the parking garage, wherein the at least one additional floor has a substantially similar layout to the first floor of the parking garage;
in response to detecting the at least one additional floor layout data for a floor of the parking garage, group by the one or more processors, the floors with substantially similar floor layout data into at least one cluster;
making a determination, by the one or more processors, that at least one of the floor layout data in the cluster contains at least one LIDAR blind spot, wherein the at least one LIDAR blind spot is determined based on the comparison of relative quality of LIDAR data from two or more substantially similar floor layout data in the cluster; and
based at least on the determination, generating, by the one or more processors, LIDAR data for the at least one LIDAR blind spot, wherein an automated vehicle control based at least in part on the LIDAR blind spot determination is used to control vehicle movement to capture data for at least one LIDAR blind spot.
