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 25

Slide 26

Slide 26 text

26 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

Slide 27 text

27 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).

43 9.C Significantly increase access to information and communications technology and strive to provide universal and affordable access to the Internet in least developed countries by 2020 + Vector Tiles even saves the bandwidth use. Vector tiles are gradually getting ready for everyone.

Slide 44

Slide 44 text

44 Just because vector tile technology is specialized, it needs a global community.
