【问题描述】:
我需要使用 mapbox-gl-js 为地图中的每个点设置不同的自定义图像,但我没有找到一种方法为功能集合中的每个功能提供自定义图标
incidentMarkers = {
"type": "FeatureCollection"
"features": [{
"type": "geojson",
"data": {
"type": "Feature",
"properties": {
},
"geometry": {
"type": "Point",
"coordinates": [
longitude
latitude
]
}
}
},
{
"type": "geojson",
"data": {
"type": "Feature",
"properties": {
},
"geometry": {
"type": "Point",
"coordinates": [
longitude
latitude
]
}
}
}]
}
map.addSource('incidentMarkers', {
"type": "geojson"
"data": incidentMarker
})
window.map.addLayer({
"id": 'incidentMarkers',
"type": "symbol",
"source": 'incidentMarkers'
"layout": {
"icon-image": "image-1",
"icon-size": 0.25,
"icon-allow-overlap": true,
"text-allow-overlap": true
}
})
现在我将每个点添加为单独的图层,以便为每个图标添加自定义图像,但是为了使用标记进行聚类,我需要将所有标记作为相同的图层,有没有办法为每个图层添加自定义图像
pointsData.forEach (data) ->
window.map.loadImage("#{data.category_image_path}", (e, image) ->
window.map.addImage("image-#{data.id}", image)
incidentMarker = {
"type": "Feature",
"properties": {
},
"geometry": {
"type": "Point",
"coordinates": [
data.longitude
data.latitude
]
}
}
map.addSource('incidentMarkers' + data.id, {
"type": "geojson",
"data": incidentMarker
})
window.map.addLayer({
"id": 'incidentMarkers' + data.id,
"type": "symbol",
"source": 'incidentMarkers' + data.id
"layout": {
"icon-image": "image-#{data.id}",
"icon-size": 0.25,
"icon-allow-overlap": true,
"text-allow-overlap": true
}
})
如果我在同一个纬度有多个标记,则仅显示一个标记,即使我将 icon-allow-overlap 选项设置为 true
