Transcript of 3dQLD Vision

3dQLD Building the boundaries and positioning Queensland About the Authors The 3dQLD vision has been prepared by a 'think tank' of senior spatial and surveying professionals from government and private enterprise. These people believe it is critical that we as professionals take a leading role in ensuring the cadastre will met the future need and deliver continued prosperity to Queensland . What will 3dQLD mean to everyday Queenslanders? Adopting the principles of the 3dQLD vision will mean many things to different people For the non-expert community! The potential for higher levels of accuracy or certainty at a local level for all spatial data (expert and non expert) This could lead to accelerated improvement in the DCDB If this happens proposals and impact analysis will be easier to interpret with a 3d Representation of the land tenure with positional certainty. Position can be better related to extent of ownership ( the people) 3dQLD also means an ongoing retention of integrity and security of the current land tenure system For expert surveying and mapping professionals 3dQLD means.. A refinement of current practice and thinking in survey methodology An enhanced sense of purpose to adapt the current cadastre to a highly efficient 21st century system. Leading the non expert spatial community in the virtual simulation of the built and natural environment Facilitating positional certainty in three dimensions to the current legal cadastre Key to a successful transition Healthy and productive private sector and government collaboration Successful consultation with allied industry bodies and investors in spatial information Efficient systems for two way data sharing between government and practicing land surveyors Surveyors embracing the opportunity that lies with progression of the current successful system to an enhanced system for the 21st century and beyond. What is the target of 3dQLD reform? The four economic pillars of the Queensland economy What are the drivers for reform? The belief is the cadastre is an under utilised asset. There will be continued public pressure on publicly managed assets The increasing reliance / misunderstanding of the DCDB as an accurate data source of legal extent of land ownership. The threat that management of the cadastre may be delegated to less qualified people who lack the capacity to manage on- going system evolution A widow of possibly 10 years before a large percentage of highly experienced cadastral surveyors retire and numbers reduce significantly How will 3dQLD work? A progressive change / not immediate but significant to facilitate change and bring the profession forward. Build a volume of accurate three dimensional land survey data over time with high positional certainty. Build on the current accepted legal system of boundary definition including maintaining adjoining interests. This database can be used to correct or improve the limitations with the current DCDB. Surveys will still performed by registered persons who are deemed competent by the Surveyors Board of Queensland Who will be critical to implementing the reform? Registered Land Surveyors are the best qualified to realise 3dQLD. Empowering the existing workforce will be the responsibility of the land surveying profession working in partnership with government, universities and training providers. 'The public' attitudes and perceptions- Opportunity for VGI (Volunteered Geographic Information) to enrich the cadastre. e.g. photos of changes in ambulatory boundaries in flood events etc. Costs of 3dQLD vision reform? 3dQLD is not a money hungry reform. It is about utilising existing resources and the public and private sector to our best advantage. Land Surveying professional will need to invest absolute positioning GNSS technology. If they don't have it already a scheme to make this affordable and accessible may need to be considered. Investment will eventually be needed to develop a system capable of managing and delivering a high quality 3d model The public costs for surveys is unlikely to change significantly even with a reduced workforce over time. This may not be the case if reforms are not introduced. What is the benefit for the public? Reduction of duplication in legal survey process over time. Greater public understanding of extent of ownership this virtual 3d animation and modeling. Benefits to the economy and environment through reduced approval times for development approval and environment assessment through greater positional certainty of boundaries and ownership. A greater public understanding of the cadastre if input of VGI (Volunteered Geographic Information) can be facilitated. What is the benefit for surveyors? A more diverse and efficient base that will facilitate greater value adding of services with new advancement in technology. A future with potential for greater opportunity and prosperity The ability to maintain the current levels of certainty and service by an expected reduced future workforce. An attractive career path for future students and new entrants to the profession. Greater public recognition of the role of the cadastre in economic prosperity How surveyors can prepare and contribute to the 3dQLD vision 1.Start playing with the DNRM globe (in 3D) and work out how opening the vault can benefit your business and your clients? 2. Look at some of the models in Google Earth (3D) and who are the authors. These people are not experts but this information can still be valuable for some users? 3.Study the DNRM Globe and the positional certainty of the DCDB and the 3d elements that currently exist with this data set, where are the opportunities and where are the limitations? 4.Look seriously at investing in GNSS if you have not already. How surveyors can prepare and contribute to the 3dQLD vision cont.. 5. Become relevant with the current CORS network, commercial suppliers of GNSS corrections, both post processed and RTK and the Auspos online processing system offered by Geosciences Australia 6. Keep up to date with the current changes in SP1 and standards for control surveys 7. Start testing and using GNSS where suitable, supported by more traditional methodology in urban and rural land surveys. Where does it work and where doesn't it work. 8. Join the conversation, participate in blog posts, and feed back to the Surveyors Boards recommendations for GNSS. start at http://3dqld.com/blog/ How surveyors can prepare and contribute to the 3dQLD vision cont.. 9. Look into developments in BIM, building information modelling and the opportunity that exists for surveyors in a virtual world. Research VANZI and BIM online. 10. Change your thinking in terms of recording and presenting in 3D. What other areas of opportunity exist say in precision agriculture or machine guidance. 11. Modernising your business or workplace to take advantage of a greater public understanding of 3D and absolute position. 12. Embrace an ever changing public perception of the profession and find the opportunities that come with it. 13. Motivate your people to embrace the opportunity that comes with change How surveyors can prepare and contribute to the 3dQLD vision cont.. 14. How do I present my survey data as a KML or KMZ file? What software can I use for this. 15. What is open source? How can this benefit me and my business? 16. Look at advancements in 3D terrestrial laser scanning and 3d point clouds. These cost may now be within reach of some small businesses and can value add to a future 3d land surveying product and service. 17.How do I adequately source or reference my data so that it can be correctly reused in the future. 3dQLD facilitating progression to a modern 21st cadastre delivering greater opportunity, prosperity and efficiency to the economy of Queensland contribute, comment and post feedback and participate via the website www.3dQLD.org or http://3dqld.com/blog/ 3DQLD LINKS POSITION WITH PEOPLE! 3DQLD IS ABOUT THE PUBLIC NEEDS OF 21ST CENTURY SURVEYORS HAVE A PROVEN HISTORY OF ABILITY TO MANAGE ONGOING SYSTEMATIC EVOLUTION 'CADASTRAL MAPS (DCDB) ARE DESIGNED TO MAKE LOCAL SITUATIONS LEDGIBLE TO AN OUTSIDER... THEY ARE A SIMPLIFICATION BUT THEY THEMSELVES HELP CHANGE REALITY.' James C Scott (Anthropologist) THE WORLD IS EVOLVING AWAY FROM 2D MAPS TO DIGITAL 3D MODELS AS A MORE REALISTIC REPLICATOR OF THE PHYSICAL WORLD It may also mean incentives for surveyors in their everyday practice relaxation of connection to two (2) PM's under current CSR item 3.26 if connection is made to the state control network greater roll out of 'globe services' to title and property information under open data policy relaxation of reference marking in some situations where the survey is accurately tied to the state control network Sharing of digital data submitted under Eplan if surveys are connected to the state control network OPEN DATA REVOLUTION WILL RELEASE AS MUCH PUBLIC DATA AS POSSIBLE FREE TO ANYONE WHO WISHES TO USE IT THE OPPORTUNITY NOW EXISTS TO TAKE ADVANTAGE OF ADVANCEMENT IN TECHNOLOGY AND THE POLITICAL WILL FOR CHANGE OTHER DRIVERS: OVERLAPPING TENURES AND 3D there is an importance particularly in mining of aligning mapping and between surface and subsurface tenures IF SURVEYORS DONT MAKE THE CHANGE TO GREATER POSITIONAL CERTAINTY SOMEONE ELSE WILL! these tenures need to be 'discoverable' as part of everyday property transactions As a result Recommendation 43 of the Qld Govt State Development, Infrastructure and Industry Committee on land tenure states

"The committee recommends that the Queensland Government integrates all tenure datasets and maps to address surface and subsurface tenure issues as a priority." Live Demo
