Mapbox vector tile MVT is missing data

由 跟風遠走 提交于 2019-12-11 16:49:02
问题 I'm trying to make my own renderer for Mapbox MVT vector tiles, but I have hit the obstacle and couldn't find the answer. My problem is that MVT tile downloaded form Mapbox server contains all roads, but only a few bulding numbers (should be much more for given area) and no land types (grean area on map) and buildings. Anyone had same problem or know the answer? link I use to download tile is: https://api.mapbox.com/v4/mapbox.mapbox-terrain-v2,mapbox.mapbox-streets-v7/18/143415/87627.mvt

Schedule a render frame if one is not already scheduled. * @returns An id that can be used to cancel the callback * @private */ _requestRenderFrame(callback: () => void): TaskID { this._update(); return this._renderTaskQueue.add(callback); } If I try to

问题 I use MapBox for my Android App, and I need to modify the standard blue "dot" that is used to indicate the current user location and orientation.

How can I query the feature that's closest to the geocode result in Mapbox?

由 纵然是瞬间 提交于 2019-12-11 12:08:49
问题 I'm trying to create a Mapbox map with thousands of points. I want the user to be able to type an address and a div to be filled with information from the closest point to that address. I'm using the mapbox-gl-geocoder control What would be perfect is if I could use something like: geocoder.on('result', function(e) { var features = map.queryRenderedFeatures(e.result.center) }); But queryRenderedFeatures doesn't accept latlong coordinates, it requires viewport coordinates.
