Topographic data machine learning method and system

Aspects described herein apply machine learning techniques for image recognition and classification to the processing of topographic imagery, in order to permit more accurate and detailed topographic representations of an area to be obtained. In particular, in one embodiment a machine learning system is trained with existing topographic imagery and corresponding topographic data relating to a particular area, so that the machine learning system is then able to relate actual physical topographical features to their topographic representations in existing data. ...

Transaction-based refresh of a long database transaction's workspace

Aspects of the present disclosure aim to improve upon systems for managing long database transactions, and the way in which changes made to a database from within a workspace view during a long transaction are committed to the underlying parent database. The present disclosure aims to solve problems caused by the need to refresh a workspace view as part of the process of resolving conflicts between competing workspace views operating on the same portions of the database. ... Ordnance Survey Limited

Circular routing

Aspects described herein provide a computer-implemented method and system of generating circular routes that start and end at the same geographical position, the route passing through a number of intermediate points along the way. The circular routes are generated in dependence on one or more route criterion, which may be pre-defined or input by the user. ... Ordnance Survey Limited

Method and system for improving spatial accuracy of map data

Aspects described herein address the above noted problems by providing a way of more accurately quantifying the spatial similarity between a feature in a first map and features in one or more further maps, specifically, by quantifying the extent to which the areas surrounding the features intersect. Some aspects described herein use this similarity test to spatially resolve two or more maps to produce a composite image of a map that comprises all of the features of both maps, wherein the features common to both maps have been spatially resolved.. ... Ordnance Survey Limited

Bulk validation of spatial topology

Aspects described herein are concerned with automatically validating spatial features of a spatial dataset. One solution is built upon a database server which performs a decomposition of the features' geometries into line segments, after which, sets of line segments are compared to detect errors in the dataset. ... Ordnance Survey Limited

Satellite positioning system authentication method and system

Embodiments of the invention provide that when performing a position fix a user who makes use of rtk or dgnss correction data from a rtk/dgnss service to obtain more accurate position fixes also receives from that same service data derived from the encrypted gnss channels that authenticates whether the position fix determined by the mobile terminal based on the rtk/dgnss data can be relied upon. By providing such an integrated service the mobile user terminal is able to obtain an authenticated, highly accurate positional fix which it can be certain can be relied upon.. ... Ordnance Survey Limited

Generalising topographical map data

Aspects described herein improve upon systems and methods for generalising topographical map data relating to the road network for use at different scale levels. Existing systems collapse the two carriageways of a dual carriageway to a single centreline representing the dual carriageway by tracking along one way sections of carriageway and generating pairs of carriageways for collapse, but fall short of being able to compute complicated intersections. ...
