1. Ministry of Land, Infrastructure, Transport and Tourism Geospatial Information Authority of Japan Application of the UN Vector Tile Toolkit (UNVT) for land information management Hidenori Vice-chair, WG-3, UN-GGIM-AP Lead, Task Group B, WG-Disasters, UN-GGIM Lead, United Nations Vector Tile Toolkit Executive Officer for Geospatial Information Policy, Geospatial Information Authority of Japan (GSI)
2. UNVT enables innovative geospatial data sharing Declaration on Navigation Policy with Data to Leave No One Behind (ESCAP/CST/2018/7) … 4. Commit to the implementation … with collaborative and integrated efforts … through the following action areas … (f) endeavoring to strengthen necessary ... institutional mechanisms to enable national statistical systems to take full advantage of new, innovative, and frontier technologies, to follow … standards of data exchange and to build partnerships with all stakeholders for data sharing … UNVT proposes to enable innovative geospatial data sharing. 2
3. Open Source Software to support the use of Vector Tile Technology by any organizations. Based on the experience in web maps for more than 15 years in GSI Established under the United Nations Open GIS Initiative WG4 in 2018. UNVT in a nutshell 3
4. Mandate of GSI for the UNVT Article 27.2 of Survey Act: Minister … must publish … maps … . → It is our Minister’s mandate to publish web maps 4

10. Experience of GSI for the UNVT 2003 GSI started web maps using the Vector Tile Technology. 2012 GSI adopted Open Source Software for the operation of its web maps. Open Source Software at that time was based on Image Tile Technology. 2014 Vector Tile Technology under Open Source License became available. GSI started GSI Vector Tile Engineering Experiment. 2015 The UN Open GIS Initiative was established. 2017 Japan contributed a basemap expert to the United Nations Secretariat. 2018 The UN Open GIS Initiative created the UNVT. 10
11. BEFORE UN enterprise web map with image tiles 11 UN data Not very responsive Detailed map not globally available
12. BEFORE UN enterprise web map with vector tiles 12 12 UN data Less responsive More details
13. AFTER Proposed UN enterprise web map using UNVT 13 UN data Building- level details with global coverage Responsive as in video games
14. UNVT also used in GSI Maps Vector (July 2019) 14
15. we the peoples of the United Nations have resolved to combine our efforts - Preamble of the Charter of the United Nations 15
16. UNVT’s contribution to GSGF Principle 4 via WG-3 Value Commitment to implementation are critical. Element 1 Implement access mechanisms that provide greater efficiency. Allow adaptation and evolution through time. Element 2 Develop common solutions. Promote reuse and avoid duplication of efforts. Element 3 Ensure that tools are free and open. No information loss or interoperability issues. 16 Principle 4

19. Prototype application for land information management 19 Agricultural land information overlaid on the latest aerial imagery.
20. Prototype application for land information management 20 Prototype application for land information management 19 Agricultural land information overlaid on the topographic map of 1880s.
21. Recent development: Tiny PC implementation 1. Server access is limited for information security and management. 2. The UNVT need to involve more participants to sustain itself. 3. Implement the UNVT in a tiny PC for demos and capacity building. USD $10 – 50 Frequently used for STEM education or IoT 21

23. UNVT contributes to global agenda by Running Code UNVT Sustainable Development Goals Sendal Framework Integrated Geospatial Information Framework Global Statistical Geospatial Framework Strategic Framework on Geospatial Information and Services for Disasters Contribute by Running Code 23 Declaration on Navigation Policy with Data to Leave No One Behind
24. UNVT is available to anyone as FOSS4G FOSS4G: Free and Open Source Software for Geospatial https://github.com/un-vector-tile-toolkit 24
25. Why is UNVT Open Source? 1. Participation – open innovation & project sustainability 2. Transparency and Accountability 3. More competition – cost reduction  e.g. GSI provides 3 billion tiles per month without cost recovery.  Serving 3 billion tiles using commercial service takes millions or ten millions of USD.  Great cost reduction was possible by using general-purpose Cloud Service thanks to Open Source Software. 25
26. Conclusion 1. Vector Tile Technology is an innovative web technology that: a. provides access to geospatial information by people. b. enables statistical geospatial integration by hyperlinking. 2. The UNVT enables: a. the use of Vector Tile Technology by public organization through a cross-sector partnership in the open source project. b. an efficient development and operation of the service. 3. We welcome your participation to the UNVT. 26
