|Title:||UPDATE DEVICE, CONTROL METHOD, PROGRAM, AND STORAGE MEDIUM|
A server device 200 is a map generation device which assigns, to voxel data in a map DB 20 which is divided into a plurality of voxels, a first weighting value for each voxel, said first weighting value being associated with the presence of moving objects and stationary objects. The server device 200 acquires upload information Iu including position information related to a travel route of a measurement vehicle during measurement of point group data required for generating or updating the voxel data. The server device 200 determines the first weighting value for each voxel, on the basis of the travel route of the measurement vehicle, said travel route having been identified on the basis of the upload information Iu.
