Simple Sample Dataset of Vector Tiles #10

Closed hallahan closed 8 years ago

hallahan commented 10 years ago

Where can we find some good vector tiles to play with and decode? I'm talking about maybe a big zip full of tiles, not an obfuscated SQLite MBTiles container.

There are some samples included in mapnik-vector-tile at https://github.com/mapbox/mapnik-vector-tile/tree/master/examples/data

There are utilities that will dump out all the files from a MBTiles container into an z/x/y directory structure.

We do not have any sample datasets in the new version 2.0 pull request (https://github.com/mapbox/vector-tile-spec/pull/39), however, the amount of encoding examples has been increased. I think I would prefer written examples over example files in the specification personally. If anyone would like to add more examples to the specification, especially around feature attributes and their encoding/decoding it would be greatly appreciated!

I'll look at doing up some examples. They're useful to have, as when implementing a decoder (like the person above) you currently have to go to another repo.

@hallahan and @pnorman - mighty late to the game here, but we have a number of valid and invalid examples over at https://github.com/mapbox/mvt-fixtures now. There aren't any that contain a ton of data, though. I'd be curious to hear if there are any others not included there that you wish to see.

Thanks @mapsam . Interesting throwback in time. Good to know!
