QRank for dynamic styling about organicmaps HOT 2 OPEN

Dynamic styling we discussed is a generic problem, not only related to POIs. What you are discussing here is more about "if we have many POIs to render, how to choose the most relevant ones to a user?".

A generic problem sounds like this: "what should be displayed at this place at this zoom level to make the map usable for the user?" It involves drawing forests/lakes/roads/towns/villages/POIS earlier if the map is empty, or later, if the map is too overloaded.

I understand that the perfect dynamic styling involves drawing forests/lakes/roads/towns/villages/POIS earlier if the map is empty, or later, if the map is too overloaded. If I understand correctly, it's technically hard to prioritize all possible map features in runtime. Hence the traditional drawing rules approach emerges.

What I suggest is a first step from hardcoded drawing rules towards dynamic styling prioritization. If it works, we could then gradually relax drawing rules more and more while also improving ranking algorithms. This way we would arrive to dynamic styling step by step, without the single major overhaul of the app architecture. The discussed QRank is pre-calculated for many features, including roads and water bodies, but it seems easier to start with POIs.
