7. 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.

    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).

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