Other Decks in Technology


  1. UNVT: recent progress Hidenori 2021-10-13 1

  2. UNVT: definiton a collection of Open Source Software (OSS) to

    produce, host, style and optimize vector tiles for web mapping. https://unvt.github.io Collaborators include: United Nations Geospatial Information Section / Global Service Centre, Geospatial Information Authority of Japan, PASCO, Geolonia, Mapbox, Furuhashi Laboratory - Aoyama Gakuin University, Japan Antarctic Research Expedition 63rd wintering party, etc. and ASIG. 2
  3. UNVT: principles 1. Use Open Source Software as a best

    way to collaborate. 2. Rely on UNIX as the standard foundation for web services. 3

  18. Appeared in FOSS4G 2021 (2021-09) 18

  19. UNVT: produce Hidenori 2021-10-13 19

  20. produce: some advices 1. Work with small data first. You

    may need to divide the task. 2. Have time on your side. You may need to iterate. 3. Ask, if you have an issue. Collaboration is our core value. 20
  21. My recent production project: a-1 Produce vector tiles for Showa

    Station, Antarctica for Japan Antarctic Research Exploration (JARE) I am going to use charites for styling. Hopefully to be introduced in out next session. raster vector 21
  22. UNVT: style Hidenori 2021-10-15 22

  23. Our problem 1. Vector Tile styling is a new technology.

    üWe need to learn https://docs.mapbox.com/mapbox-gl-js/style-spec/. üOther existing style language such as SLD does not look good enough. 2. Base map styling is too complex. üWe can divide style description layer by layer. üCurrent solution: Use Human-Optimized COnfiguration Notation (HOCON) 23

  28. https://github.com/optgeo/durana This is what I have provided to you 8

    months ago. 28
  29. Possible questions and answers lIs there GUI for styling? 1.

    You need to pay if you want to have it. Ø GSI Maps Vector has GUI style editor made for GSI data. Ø https://maps.gsi.go.jp/vector/index.html 2. Basemap styling is too complex for GUI tools. lIs this method already established? No. We are making progress. 29
  30. https://github.com/unvt/charites • An easy, intuitive, and efficient command-line tool for

    writing vector map styles. • Transferred to the United Nations Vector Tile Toolkit just yesterday, after collaborative interaction with Geolonia, a start-up company in Tokyo, Japan. • Geolonia provides a web map produced from a mixture of GSI data, OpenStreetMap, Natual Earth, etc. 30

  32. Simpler syntax that reduces errors 32 JSON HOCON YAML

  33. Improvements •JSON ↓ no quotes (“) and commas (,) •HOCON

    ↓ no brackets ({} & ()) •YAML 33
  34. UNVT: host Hidenori 2021-10-21 34

  35. produce - voxel tiles host - FTS style - charites

    optimize use - storytelling New developments 35
  36. FTS FTS is a tile service Tiling and hosting, free,

    as in freedom * Ghostscript Tiger is AGPL-ed. 36

    •Fun Tile Service 39
  40. A recent problem with UNVT 1. UNVT is available to

    everyone because of its Open License. 2. However, it requires too many ICT skills. 3. What if we can provide the computing environment in a single physical package, ready to be used? 4. FTS Kit - FTS in a single physical package? 40
  41. Expansion of UNVT UNVT optgeo FTS EV 41 FTS Kit

  42. FTS Kit: concept 42 FTS Kit USB 5V
