Abstract: The present invention concerns a method for determining a conformity between a representation of an environment and said environment, wherein said representation of the environment constitutes a representation in at least two dimensions, where a distance between two points in the representation has a known relation to the corresponding distance in said environment, characterized in that said determination involves the step of determining a first set of parameter values for a first position in said representation of the environment, comparing said first determined set of expected parameter values with a second set of parameter values, where said second set of parameter values has been determined for a second position, where said second position constitutes a position in said environment that essentially corresponds to said first position, and using said comparison to determine a measure of conformity between said environment and said representation of the environment.
