‘Open Standards the Gateway to Interoperability?’ John Tate, Team SPARTA Geospatial Technical Lead (LMUK) 29th September 2010
Agenda • What is CGTS? • Why CGTS? • Open Standards Approach • The End Game • Benefits & Challenges
What is CGTS? • A 29-month UK MOD ‘demonstrator’ research project led by Team SPARTA: • Lockheed Martin UK IS&S (Lead) • Actica Consulting Ltd • Envitia Ltd • ESRI (UK) Ltd • Helyx SIS Ltd • With support and governance from MOD and Dstl. • The research seeks to deliver the technical evidence and conduct de-risking activity to support a future UK Defence Programme(s) to deliver: • Coherent and standardised services and tools. • Support for connected, disadvantaged and disconnected user. • The name is misleading – its not about a software tool kit – it is about the delivery of a common and coherent geospatial capability
Why CGTS? • Issues: • Mapping organisations create products not data. • Proprietary systems and data. • Piece meal procurement. • Multiple tools for the same task. • Lack of Combined/Joint Concepts and Doctrine and MOD ‘geo’ Vision
So What? System B • Islands of non-harmonised data • “Stove Pipes” or “Towers of Excellence” • In order to share: • Multiple exchanges required • Lack of integrated and interoperable systems • Leading to: • Multiple copies of the same data • Information and configuration management issues • Information incoherence • Increased training burden • Unable to support high tempo operations System A Air-gap only System C Re-format Format X Direct Transfer Format Y System E System D
CGTS Evidence • Not just a paper study assessments and demonstrations are important elements • Assessment: • Two weeks each for 7 GIS vendors • 2012/15 representative test rig including: standalone, LAN & WAN • 24 tests, 1,000+ iterations per vendor • Demonstrations: • Coalition Warrior Interoperability Demonstration 2009 (Jun 10) • Geospatial Capability Demonstration (Feb 10) • Geospatial Capability Demonstration (Oct 10)

Geospatial Capability – Services • Through detailed requirements capture identified the “services“ required to deliver the coherent geospatial capability. • Service groupings and descriptions coherent with MOD Spatial Data Infrastructure (SDI) initiative. • Terminology focussed at the non specialist. DISCOVER & RETRIEVE COLLECT & CREATE MANIPULATE & TRANSFORM VISUALISE ANALYSIS PRINT & EXPORT INFORMATION MANAGEMENT
Open Standards • The reason open geospatial standards are important : • Bring more customer value through: • Reduce risk by increasing available options • Reduce dependency on a particular vendor • Ease integration with customers existing systems • Increase data availability and maintainability • Necessary component for the integration of large systems • Open Geospatial Consortium (OGC) Standards • Corner stone of many defence and non-defence programmes. • NATO Core GIS … • EU INSPIRE … • UK MOD’s Common Geospatial Tool Set … • UK British Transport Police, Metropolitan Police … • OGC becoming more evident in non-traditional GIS applications
UK Defence – SPATIAL DATA INFRASTRUCTURE • BENEFITS • Coherent capability • Improved Shared Situational Awareness • Effective Decision Making • Improve Tempo of ‘operations’ • Improved collaboration and sharing of information Proposed SDI for UK Defence (developed by Dstl under GEAR – informed by CGTS)
OGC Standards are they sufficient? • Current OGC Standards could: • deliver against ~75% of geospatial capability needs with profiling activity • ignoring data management & print capabilities this rises to ~93% • Deltas exist and grouped as follows: • Profiling activity e.g. WMS as well as WPS profile for line of sight etc • Current OGC standard development e.g. WCPS for re-sampling • No standard exists or is in development e.g. printing / plotting services • Services that are outside OGC e.g. export services • Web services also evaluated as a viable data access mechanism
Service Implementations • Evaluated OGC services provided by GIS multiple GIS vendors across multiple infrastructures in both test and demonstration environments. • Web services proved to be viable but a range of implementations are required – one size does not fit all. • Need to balance: • Performance v flexibility v number of anticipated users • Single CRS but multiple services v multiple CRS and single service • Single layer but many services v Many layers and single service • But … • what needs to be common and open is the service and profile used to deliver the implementation
OGC Profiles • Evidence indicates vendor OGC implementations differ . • Barrier to interoperability • Profiles needed to ensure that standards delivered in ‘standardised’ manner. • Profiles valid for both consumers and publishers • Test scripts needed to ensure compliance • Need to be focussed on the ‘warfighter’ not just data producers • Further staffing of profiles currently on going for WMS, WFS and WCS Web Map Context/ KML Styled Level Descriptor Web Map Service Geographic Mark-up Language Web Coverage Service Web Feature Service Web Processing Service Profile Priority: 1 2 3 Test Script
OGC Standards – Issues and Needs • Security remains a potential issue • Standards don’t support the need to tell the ‘service’ who is making the request but … • GeoXACML offers an approach for fine grained access control • Configuration management of standards • To manage changes and updates to current and future standards • Governance / mandating by a body with appropriate authority • To ensure that the standards are adopted by projects • Need for a persistent test bed • To test consumers and publishers to ensure they conform to the standards and profiles • MOD need to increase their OGC influence • We will present our findings to the OGC Technical Committee (TC) at the December 2010 TC (Sydney, Australia)
The End Game Find Bind Bind Publish
OGC Standards supporting interoperability • Build on existing capabilities • Enhance and enable rather than replace – in many cases most of the key components already exist • Standards are essential but not sufficient … • Need to ‘profile’ – the ‘route card’ through the standard • Need to test compliance against the standard and the profile • Need to mandate and govern usage – both publishers and consumers • ‘Tailored’ Geo capability dictated by user needs – not everyone needs a “GIS”. • Services support ‘controlled’ and ‘managed’ access to data. • Able to tailor the ‘view’ to meet the users needs.
Interoperability: Via open web services Increased operational effectiveness: Sharing of data, removal of data silos Improved Shared Situational Awareness & Understanding: Consistency of viewed data across a range of platforms/applications Integration of: Multiple data sources, Multiple applications (& vendors) Multiple network bandwidths Support to disadvantaged/ mobile users.
