How can I get the currently visible layers / points

[nrbnlulu]

the use case is i.e if I have a layer for all market places, if I zoom in enough I want to fetch and display all the stores inside that market place

[nrbnlulu]

I assume this can be done using zoom level and center latlng but need the math 🤓

Hi, @nrbnlulu . So I guess you have a feature layer with marketplace polygons, and another feature layer with store polygons or points? In that case you can use CartesianPoint2d::is_point_inside or geo crate algorithm https://docs.rs/geo/latest/geo/algorithm/contains/index.html . Or did I misunderstand your question?

Hi, I think you did. but is_point_inside what?
the goal is not to fetch all stores at once (for all markets) in order not to bloat your server / app with API calls.
