2 Drivers The last 2-3 years have seen a sea-change in capability, capacity and demand within the GI market in terms of data, software/systems and from users requirements As technological constraints recede, customers are demanding much more not only of content in its own right but also in terms of how it is structured to better model (rather than simply depict) the real world

3 OS changes New OS geospatial infrastructure means we now have improved capacity and capability to focus on content We have a more coherent sense of users current needs with regard to better representation of features and also what our users may need in the future And as a result Our Product Strategy includes a substantial focus on improving our most detailed (large-scale) content

4 What are our customers looking for? Customer feedback over the last year has remained consistent and given us strong guiding principles for: Consistency of content between legacy scales Increased cartographic flexibility Structural representation of topographic features - greater emphasis on what a feature is in addition to what it looks like from above More feature attribution and maintenance requirements A shift from a 2D data structure to one which is 3D-ready Greater usability especially in ordering, order fulfilment and consumption Unclassified

5 Greater simplicity in our portfolio Products which add context to user information and for which cartographic design is essential Data products which provide structure and descriptive information and to which users can add their own reference information Services which enable ease of access and greater usability across our portfolio of products

6 Geographic Content Improvement Unclassified

7 Evolution of the large scale specification There has been a number of decisions/policies made throughout the evolution of large scales data in relation to capturing against specification and frequency of update for certain feature types Historically surveying technical limitations have meant that change has had to be prioritised in order to produce the volumes required to reflect the most significant topographic changes throughout GB The more minor change (category b and c) in urban areas has not been systematically swept before

8 Enhancing our most detailed content 1. Deliver consistency of content. Ensure that real-world objects are captured, modelled and maintained in a consistent fashion, and reduce the legacy of paper-based map scales. 2. Maintain what we capture. Remove disparities between what we survey on construction and those subsequent real-world changes that are not always maintained. 3. Improve the way we describe features. Improve the attribution associated with a feature, particularly in terms of its form and function, in addition to what it looks like from above. 4. Shift from a purely 2D data structure to one which is 3Dready. Put in place the basic enhancements that will allow large-scale topographic products to be utilised in a 3D context. Unclassified

36 The third dimension, part 3 Towards 3D Topographic data Unclassified

37 Two centuries of learned behaviour We carefully survey urban landscapes and model them in 2D and many of our customers then use this 2D data to help make decisions which are inherently 3-dimensional. Slide 37

38 Buildings and what else? Buildings only Buildings plus DTM 3D topography Slide 38

39 Topography in 2D and 3D Common maintenance and shared architecture 3D topography product National Geographic Database Aspired common characteristics: Shared geometry Common IDs Synchronised maintenance OSMM Topography Layer 3D topography as an upgrade from OS MasterMap Topography Layer Slide 39

40 Towards 3D: Sheffield illustrative data only Slide 40

41 Next stages in 3D We are committed to accelerating our 3D development activity with an emphasis on understanding customer use cases and associated business value We are clearer in our vision of what our 3D topography product could be: an upgrade to Topography Layer, focused on urban areas and including all major topographic feature classes built using a bottom-up approach where feasible in order to ensure interoperability with Topography Layer in terms of both geometry and TOIDs Simple building height data has recently been published via OS Insight; illustrative 3D topographic data to follow soon We want to work closely with technology suppliers, partners and users to ensure that 3D can be accessed and consumed as easily as possible Slide 41
