1. A method performed by an apparatus, said method at least comprising:
- generating or obtaining a radio map, comprising a plurality of sets of positioning reference data, wherein at least one set of positioning reference data of the plurality of sets of positioning reference data comprises;
a respective position information obtained or generated based on position-related information from at least one sensor, anda respective signal characteristic representation of signal strength associated with at least one received signal from at least one wireless coverage providing entity, the respective signal characteristic further comprising an identifier of the at least one wireless coverage providing entity,the method further comprising,obtaining at least a first manual position information and a second manual position information, each of which is associated with at least one position information received from a user interface, andcorrecting at least one position information of a set of positioning reference data of said plurality of sets of positioning reference data based on said at least a first manual position information and a second manual position information, said correcting comprising;
estimating a trajectory representation between said first manual position information and said second manual position information using indoor map information, wherein the estimated trajectory information is a shortest route between the first manual position information and the second manual position information that matches the indoor map and does not violate a barrier of the indoor map, andcorrecting said at least one position information based on the estimated trajectory representation.

10. A computer program product comprising a non-transitory computer-readable medium having computer executable computer program code stored thereon, which when executed by a processor causes an apparatus to:
-
generate or obtain a radio map, comprising a plurality of sets of positioning reference data, wherein at least one set of positioning reference data of the plurality of sets of positioning reference data comprises; a respective positioning information obtained or generated based on position-related information from at least one sensor, and a respective characteristic representation of signal strength associated with at least one received signal from at least one wireless coverage providing entity, the respective signal characteristic further comprising an identifier of the at least one wireless coverage providing entity, and further causes the apparatus to; obtain at least a first manual position information and a second manual position information, each of which is associated with at least one position information received from a user interface, and correct at least one position information of a set of positioning reference data of said plurality of sets of positioning reference data based on said at least a first manual position information and a second manual position information, said correcting comprising; estimating a trajectory representation between said first and second manual position information using indoor map information, wherein the estimated trajectory information is a shortest route between the first manual position information and the second manual position information that matches the indoor map and does not violate a barrier of the indoor map, and correcting said at least one position information based on the estimated trajectory representation. - View Dependent Claims (18)
