Re: Reduce the size of the vector tiles at low zoom levels

[Chapuis Bertil <be...@icloud.com.INVALID>]

Hello Everyone,

Thanks to Leonard’s work, we significantly reduced the size of the vector tiles. We also added some inspection tools to the dev mode. These changes now appear in the demo [1].

I think most of the tiles now weight less than 1mb. We still have some work to do, but we get closer to the 250kb goal. Also, the simplifications take about three day to compute for the planet. If some of you have ideas or experience to share regarding tile size and performance, do not hesitate to share your thoughts in [2].

Best,

Bertil
