In the samples I see a lot of static GeoJSON being used to provide shape layer data but none where the layer data is fetched from a service which could query a source and return only the GeoJSON for the current map bounds, perhaps also dependent on the zoom.
My challenge is to integrate a database with plenty of shapes (polygons) in it so querying the database is the only realistic option we have. In the end, new shapes would also be created through the map and saved to the database but for this questions purpose I am only interested in querying and returning the correctly formatted GeoJSON based on the current bounds and zoom.
Does the map control support passing the bound and zoom parameters to the service behind a GeoJSON URL? If so, what are these parameters and would you be able to point me to the related documentation or create a new entry explaining and demonstrating this feature.
