14. A system comprising:
one or more processing units to:
decompress a compressed RADAR packet, the decompressing being based at least on one or more pre-computed encoding trees used to compress the RADAR data packet, the RADAR packet including one or more RADAR point clouds each associated with one or more RADAR scans respectively performed by one or more RADAR sensors; and
generate RADAR map data associated with a geographical area based at least on combined RADAR data that includes first RADAR data of the RADAR data packet and second RADAR data of one or more other RADAR data packets, the combined RADAR data including a plurality of RADAR data sets, each respective RADAR data set being obtained by one or more sensors disposed on a corresponding ego-machine during traversal through the geographical area by the corresponding ego-machine.
