Mapbox GL 3D single building highlight selection

由 纵然是瞬间 提交于 2019-12-10 11:05:35
问题 How can I highlight one single 3D building when hover over it? Something like the OSM buildings highlight feature. It seems the mapbox streets v7 building layer feature properties are so few, it only includes: extrude height min_height type underground There is no unique property to differentiate the building. Is there a way to include the address of the building or some unique ID? 回答1: I do not think there is a unique per-building id in the Mapbox Streets v7 tileset. You may need to build

问题 Is there a way to change a mapbox-gl-js icon-image color? This code taken from https://www.mapbox.com/mapbox-gl-js/example/geojson-markers/ won't change the marker color to red map.addLayer({ "id": "markers", "type": "symbol", "source": "markers", "layout": { "icon-image": "{marker-symbol}-15", "text-field": "{title}", "text-font": ["Open Sans Semibold", "Arial Unicode MS Bold"], "text-offset": [0, 0.6], "text-anchor": "top" }, "paint": { "text-size": 12, "icon-color" : "#ff0000" } }); I've

Mapbox GL using external maps

由 只谈情不闲聊 提交于 2019-12-09 05:50:53
问题 I want to use Mapbox GL in my Android application. This service is going to be released soon and I have a tricky question about using the renderer. I like the renderer itself, but I really want to use my own maps data in the application (not the data, offered by Mapbox and which is paid). For instance, I want to parse OpenStreetMaps data on my own, customise it somehow and then put inside of a renderer to show it in my application. And now the question: is it possible to use my own maps data

How can I show the count of points in the particular latitude and longitude in Mapboxgl?

问题 I want to show the marker as well as the number of points available in a particular latitude and longitude. I expect something Similar as above. But i have added another 2 layers to show different color and number on it. If I do this way, I am getting "undefined" error while showing popup. Since the data takes from the other layer. If it takes from layer "locations" it works as expected. But when we have multiple occurences popup content shows "undefined". Below is my implementation output

Mapbox GL Popup .setDOMContent example

问题 I'm trying to create a customized button to appear on a pop up which generates a dynamic link (a URL). I don't seem to be able to do this via the .setHTML because of the timing, can't bind a button to a function at runtime. So I thought I'd try the newish .setDOMContent There's zero information online as to how this feature works. I'm wondering if anyone has an example of this where a button is added to the popup that can run a function and send data. Here's my very poor attempt at setting

I want to implement clustering in my map. I found example of simple clustering from Mapbox Cluster Example but My code is here , where marker ==> {marker-symbol} is from studio. but it is not working. Is it possible to achieve output of cluster? Solved By following code var layers = [ [150], [20], [0] ]; layers.forEach(function(layer, i) { map.addLayer({ "id": "cluster-" + i, "source": "markers", "type": "symbol", "layout": { "text-field": "{point_count}", "text-font": [ "Arial Unicode MS Bold" ], "text-size": 13, "text-anchor": "bottom", "icon-image": "emptyMarker", "icon-size": 0.25 },

I am redrawing layers on style.load event and removing the layers map.on('style.load', function() { loadByBounds(tempBounds) }); function loadByBounds(b) { if (map.getLayer("cluster-count")) { map.removeLayer("cluster-count"); } ... map.on('click', 'unclustered-point', function(e) { var popup = new mapboxgl.Popup() .setLngLat(e.features[0].geometry.coordinates) .setHTML(text) .addTo(map); })} But how to remove map.on('click') events? As when I click the point the Popup() displays 2 times. And when I change layer one more time the onclick event fires 3 times and so on. So I think I have to
