Leaflet之历史轨迹回放 话不多说直接放图 点位历史轨迹回放 近期在接触到这个功能的时候一直使用的是Leaflet 的一个插件 Leaflet.MovingMarker 演示程序 点击这里 源代码名称: Leaflet.MovingMarker 源代码网址: http://www.github.com/ewoken/Leaflet.MovingMarker Leaflet.MovingMarker源代码文档 Leaflet.MovingMarker源代码下载 这里呢他的效果是直接将线区域直接渲染完成，这里我做一个小的改动 首先marker点位按照数据进行移动 this.map.fitBounds(这里是我们的点位数据) // 将地图视层尽可能大的设定在给定的地理边界内 var marker2 = L.Marker.movingMarker(点位数据格式与marker内的一样[lat,lng], 10000 '//动画时长', { autostart: true, loop: false, icon: policeCarIcon, rotate: false }).addTo(this.map) //后面这些可以参考上面的插件文档进行解读 然后我们要考虑如何将线绘制到图层上去 ： 这里我的思路是这样的， 通过监听Marker点位的移动进行线绘制 （暂时我的思路是这样的

Buefy steps and tabs block Leaflet map

由 二次信任 提交于 2020-08-10 19:48:57
问题 I have an issue with loading Leaflet map using Vue.js and Bulma stepper components (via Buefy). If map is placed inside stepper then it does not load all tiles until browser window is resized. If map is placed outside of Bulma stepper component then it loads without any issue. How to get this working ? Example with the issue: https://codepen.io/alxxnder/pen/zyYxwd Example without the issue: https://codepen.io/alxxnder/pen/LMYEjr <b-steps> <b-step-item label="Account" icon="account-key"> <LMap

How to disconnect a polyLine between a series of markers and start a new one in leaflet?

由 我怕爱的太早我们不能终老 提交于 2020-08-10 18:55:20
问题 I am using leaflet. I can add markers on my map and connecting them with polyLine method. Here is the link to my current code here. As of now, the way code is working is, you can start from point A and then to point B and then to Point C and so on. So it's a continuous chain of points which are connect with Polyline. What I want is I want to give an option to the user like on press escape or having a click option on div. I want user to break this chain and let him start over adding markers on

Leaflet: How to display a Geojson file with AutoCAD data?

由 放肆的年华 提交于 2020-08-08 06:18:12
问题 I am tried to display geojson file (converted from AutoCAD file to geojson) as the Second layer (first layer maps OSM ). But geojson content occupies entire maps, not in a specific location. How can we change coordinates in geojson file or how to reduce the height and width of geojson(second layer)? Please find below the Sample geojson file... { "type": "FeatureCollection", "name": "entities", "crs": { "type": "name", "properties": { "name": "urn:ogc:def:crs:OGC:1.3:CRS84" } }, "features": [

R Leaflet: Zoom Control Level

由 ☆樱花仙子☆ 提交于 2020-08-07 04:03:09
问题 I am trying to set zoom out maximum in my R Leaflet map. I follow an example of a previous question/answer in Prevent zooming out in leaflet R-Map? , but it doesn't work. The line that should be able to do this is: options = providerTileOptions(minzoom = 1, maxzoom = 10)) Can you guys can help me to figure out why? Here is code: deck_lf_par_map <- leaflet(lpoints) %>% addPolygons(data = dio, noClip=T, weight = 4, dashArray="5, 1", color = "black", fillOpacity = .01, smoothFactor = 0) %>%

angular component into leaflet popup

由 余生长醉 提交于 2020-08-06 12:47:08
问题 can't figure out how to generate a component into a leaflet popup. I've tried two things: First, integrate the component selector into the html but it looks as if angular does not compile it: let my geojson = L.geoJSON(data, { onEachFeature: (feature, layer) => { let popup = L.popup().setContent('<app-component-detail></app-component-detail>'); layer.on({ click: () => { layer.bindPopup(popup); } }) } }).addTo(map); When i click on a point on the map, the popup is empty. Then i considered

Inverted Y axis of custom tile images names

由 隐身守侯 提交于 2020-07-22 14:28:45
问题 There is a know problem of Leaflet that when you use a custom tile provider, not with real earth images, set crs: L.CRS.Simple , Leaflet queries for images where Y coordinate is inverted in comparison to the math axis. So the first top-right image's location is 1x-1 instead of 1x1 . In the internet topics about inverting Y axis are rather old, so my question is: nowadays is there a normal short and built-in way to invert queried Y axis? The only old solutions I've found were rewriting Leaflet
