  5. The idea behind the UN Vector Tile Toolkit 7 Open

    Source is a best way to make our basemaps as good as dominant web map platforms, using the vector tile technology.
  6. UN Vector Tile Toolkit Objective To facilitate the production of

    vector tiles for basemaps by public organizations. Structure Import Produce Host Style Optimize Existing datasource e.g. PostGIS, Shapefile, GeoJSON Tippecanoe Maputnik Interoperable with both Open Source and other frameworks. Tailor-made Node.js scripts Openly maintained on GitHub. Maximum use of existing OSS while adding tailor-made scripts shared openly. vt-optimizer 8
  7. 9 Technical details Import data and assign layer names and

    zoom levels. Custom open source scripts. Create vector tile packages in mbtiles format. Tippecanoe Host modular vector tile packages in a simple and scalable manner. Custom open source scripts. Style hosted vector tiles. Maputnik Enhance the optimization of the size of individual vector tiles by visualizing them. vt-optimizer and other custom open source scripts. Import Produce Host Style Optimize
  8. 10 The UN Vector Tile Toolkit is a collection of

    tools, rather than a monolithic DB/Server suite. Because: ü Inputs are diverse. ü Depolyment environments are diverse. Flexibility is the core value. And sometimes the server shall be isolated from the master database (for security and scarability).
