将哨兵图层添加到传单地图 [英] Add sentinel layer to leaflet map

问题描述

这就是我如何定义我的 url 以获取 sentinel 的 wms 图像:哨兵2:

This is how i define my url for get wms image for sentinel: Sentinel2:

"https://kade.si/cgi-bin/mapserv?SERVICE=WMS&VERSION=1.3.0&REQUEST=GetMap&FORMAT=image/jpeg&TRANSPARENT=true&LAYERS=Landsat-8&TILED=true&format=image%2Fvnd.jpeg-png&WIDTH=320&HEIGHT=320&CRS=EPSG%3A3857&STYLES=&MAP_RESOLUTION=112.5&BBOX={x}{y}{x}{y}",

我在定义如何获取 &BBOX={x}{y}{x}{y}

在这张图片中我看到请求是成功的

In this image i see that the request is successfull

但是当我复制请求 URL 时，我看到了这条消息:

But when i copu the request URL I see this message:

<ServiceExceptionReport xmlns="http://www.opengis.net/ogc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="1.3.0" xsi:schemaLocation="http://www.opengis.net/ogc http://schemas.opengis.net/wms/1.3.0/exceptions_1_3_0.xsd">
<ServiceException>
msWMSLoadGetMapParams(): WMS server error. Wrong number of arguments for BBOX.
</ServiceException>

如何设置正确的Bbox参数..

How to set the right Bbox parameteres..

我读过那个bbox

地图范围的边界框.值为 minx,miny,maxx,maxy，以 SRS 为单位.

Bounding box for map extent. Value is minx,miny,maxx,maxy in units of the SRS.

这也是有效的请求网址:

Also this is working request url:

https://kade.si/cgi-bin/mapserv?SERVICE=WMS&VERSION=1.3.0&REQUEST=GetMap&FORMAT=image/jpeg&TRANSPARENT=true&LAYERS=Landsat-8&TILED=true&format=image%2Fvnd.jpeg-png&WIDTH=320&HEIGHT=320&CRS=EPSG%3A3857&STYLES=&MAP_RESOLUTION=112.5&BBOX=2861802.338996999%2C5390950.730896911%2C2866694.30880725%2C5395842.700707162

为什么bbox参数这么长的数字:BBOX=2861802.338996999%2C5390950.730896911%2C2866694.30880725%2C5395842.700707162

Why bbox parameters are so long numbers:BBOX=2861802.338996999%2C5390950.730896911%2C2866694.30880725%2C5395842.700707162

你能帮我在 bbox 参数中添加什么，以便传单获取正确的参数并查看图层...

Can you help me what to add in the bbox parameter so leaflet to get the right parameters and to view the layer...

推荐答案

解决方案:

Javascript

// Declare map using EPSG3857 projection (default is also 3857, so just optionnal here) and set center
const center = [38, 20.472157];
const map = L.map('map', {
    crs: L.CRS.EPSG3857
}).setView(center, 4);

// Define wmsOptions for wmsLayer
const wmsOptions = {
    layers: 'Landsat-8',
    transparent: true,
    format: 'image/png'
}

// WMS Layer constructor
const wmsLayer = L.tileLayer.wms('https://kade.si/cgi-bin/mapserv', wmsOptions);

// add To the map
wmsLayer.addTo(map);

不要忘记为 div 地图设置高度:

Don't forget to set a height to the div map :

样式 CSS:

<style>
    #map {
        height: 500px;
    }
</style>

HTML 元素:

<div id="map"></div>
