Ideas about rendering

[kylebarron]

How should layers be created from the spec?

new DeckglStyleSpecLayer({...})

Props:

• Style JSON
• features (optional, because I can download them from the style json sources section. If provided, layer names must match.)

Then inside renderSubLayers I render individual layers.

How should the data process work?

• Render individual deck.gl layer for every layer object in the Style JSON? I'm not sure what the overhead is on number of layers, but that seems like a lot, especially if rendered as a sublayer of a tile layer. You could have 20+, 50+ layers per tile. That seems like too much.
• Then the other option is to combine Style JSON layers into a single Deck.gl layer per type of data. I.e. only ~3 layers would be rendered as sublayers of the style spec layer, one PathLayer, one SymbolLayer, one TextLayer (though start with the PathLayer).

I think the latter option makes more sense, so the following will pertain to that.
