1. A method of localizing a device within an environment, the method comprising:
acquiring a first location information that is representative of a first specified position within the environment;
acquiring a first sensor information that is representative of the first specified position within the environment;
allocating the acquired first sensor information to the acquired first location information to generate a first condition information that is unique for the first specified position within the environment;
providing a knowledge base having stored therein a plurality of condition information comprising at least the first condition information;
using the plurality of condition information stored in the knowledge base to establish a multi-dimensional map for at least a portion of the environment, wherein the multi-dimensional map assigns one condition information of the plurality of condition information to each one of a plurality of specified positions within the environment;
providing, by the device, a current sensor information indicating a current condition of the environment present at the current position of the device; and
localizing the device within the environment based on a matching between the current sensor information and the plurality of condition information stored in the knowledge base.
