Abstract
Techniques are discussed for using multi-resolution maps, for example, for localizing a vehicle. Map data of an environment can be represented by discrete map tiles. In some cases, a set of map tiles can be precomputed as contributing to localizing the vehicle in the environment, and accordingly, the set of map tiles can be loaded into memory when the vehicle is at a particular location in the environment. Further, a level of detail represented by the map tiles can be based at least in part on a distance between a location associated with the vehicle and a location associated with a respective region in the environment. The level of detail can also be based on a speed of the vehicle in the environment. The vehicle can determine its location in the environment based on the map tiles and/or the vehicle can generate a trajectory based on the map tiles.
