Generating segment data

A system for generating a scenic rating for segments of an electronic map, the segments representing navigable elements of a network of navigable elements within a geographic area covered by the electronic map, the system comprising:

• at least one processor;
• and
• a memory;
• the at least one processor configured to:
• obtain positional data relating to the movement of a plurality of devices with respect to time in the area;
• for each one of a plurality of segments of the electronic map:
• identify a set of positional data relating to the movement of devices along the navigable element represented by the segment;
• filter the identified set of positional data relating to the movement of devices along the navigable element represented by the segment based on one or more criteria to obtain one or more subsets of the identified positional data relating to the movement of devices along the navigable element represented by the segment which may be expected to relate to traversals of the navigable element for recreational purposes, wherein the criteria include mode of transport with which the devices are associated and/or a time of traversal of the navigable element represented by the segment;
• use the or each obtained subset of the positional data to obtain one or more scenicity parameters for the segment;
• and
• use the one or more obtained scenicity parameters to determine a scenic rating for the segment;
• and
• for at least some of the plurality of segments representing navigable elements for which a scenic rating is determined, generating data indicative of the obtained scenic rating for the segment, and associating, in the electronic map, data indicative of the scenic rating with the segment to which the scenic rating relates.

A non-transitory computer readable storage medium storing program code which, when executed by a processor, causes the processor to perform a method for generating a scenic rating for segments of an electronic map, the segments representing navigable elements of a network of navigable elements within a geographic area covered by the electronic map, the method comprising:

• obtaining positional data relating to the movement of a plurality of devices with respect to time in the area;
• for each one of a plurality of segments of the electronic map:
• identifying a set of positional data relating to the movement of devices along the navigable element represented by the segment;
• filtering the identified set of positional data relating to the movement of devices along the navigable element represented by the segment based on one or more criteria to obtain one or more subsets of the identified positional data relating to the movement of devices along the navigable element represented by the segment which may be expected to relate to traversals of the navigable element for recreational purposes, wherein the criteria include mode of transport with which the devices are associated and/or a time of traversal of the navigable element represented by the segment;
• using the or each obtained subset of the positional data to obtain one or more scenicity parameters for the segment;
• and
• using the one or more obtained scenicity parameters to determine a scenic rating for the segment;
• and
• for at least some of the plurality of segments for which a scenic rating is determined, generating data indicative of the obtained scenic rating, and associating, in the electronic map, data indicative of the scenic rating with the segment to which the scenic rating relates.
