OpenLayers:将GPS坐标转换为EPSG:25832
我想通过点击按钮获得GPS坐标,并将其更改为EPSG:25832格式以使地图居中。以下是我到目前为止编写的代码:OpenLayers:将GPS坐标转换为EPSG:25832,openlayers,Openlayers,我想通过点击按钮获得GPS坐标,并将其更改为EPSG:25832格式以使地图居中。以下是我到目前为止编写的代码: jQuery('#btnGPS').click(function() { if (navigator.geolocation) { navigator.geolocation.getCurrentPosition(success); } else { alert("Not Supported!"); } }); function success(posi
jQuery('#btnGPS').click(function() {
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(success);
} else {
alert("Not Supported!");
}
});
function success(position) {
alert(position.coords.longitude + ',' + position.coords.latitude);
var SRS_MAP = new OpenLayers.Projection("EPSG:25832");
var SRS_LONLAT = new OpenLayers.Projection("EPSG:4326");
var center = new OpenLayers.LonLat(position.coords.longitude,position.coords.latitude);
var test = center.transform(SRS_LONLAT,SRS_MAP);
alert(test);
}
最后,我的地图对象:
map = new OpenLayers.Map('map',{
controls: [
new OpenLayers.Control.Navigation(),
new OpenLayers.Control.PanZoomBar(),
new OpenLayers.Control.ScaleLine(),
new OpenLayers.Control.KeyboardDefaults()
],
projection: new OpenLayers.Projection("EPSG:25832"),
displayProjection: new OpenLayers.Projection("EPSG:4326"),
units: 'm',
maxExtent: new OpenLayers.Bounds(356570.500,5442150.416,383807.687,5462691.920),
maxResolution: 'auto',
numZoomLevels: 8
});
我总是得到相同的坐标,没有任何变换。带有lon和lat的Position对象工作正常,但我无法使OpenLayers转换函数正常工作。我正在使用最新的标准OpenLayers
我是OpenLayers的新手,所以请详细说明解决方案。提前感谢。您需要使用proj4js。以下是OpenLayers的说明链接:。 确保按照说明添加EPSG:25832的定义
