PHP-将xy.shp坐标转换为谷歌地图lat/lng

我正在开发一个web应用程序，其中可以加载.shp文件。其想法是识别该文件，然后在谷歌地图中显示每个多边形。我可以用php读取形状文件。问题是我不知道如何将.shp中使用的坐标系转换为可以识别谷歌地图进行地图操作的坐标系。以下是.shp文件的一些坐标以及该文件中使用的坐标系：

坐标系（.prj文件）：

注意：为了读取.shp文件，我使用gasparesganga/php形状文件库，

您可以使用库proj4ppp来重新投影坐标

$proj4 = new Proj4php();

// Your initial projection information from your .prj file
$srcProj    = new Proj('LOCAL_CS["CH1903+ / LV95",UNIT["metre",1,AUTHORITY["EPSG","9001"]]]', $proj4);

// WGS84 (for google map)
$dstProj  = new Proj('EPSG:4326', $proj4);

// Your original point
$srcPoint = new Point(2645165.87317, 1132484.62903, $srcProj);

// Create your new point in WGS84 projection
$dstPoint = $proj4->transform($dstProj, $srcPoint);

您正在寻找的术语可能是“reproject”，我不确定PHP中有哪些工具。您需要从瑞士坐标系（？）重新投影到投影的WGS84坐标，另请参见

$proj4 = new Proj4php();

// Your initial projection information from your .prj file
$srcProj    = new Proj('LOCAL_CS["CH1903+ / LV95",UNIT["metre",1,AUTHORITY["EPSG","9001"]]]', $proj4);

// WGS84 (for google map)
$dstProj  = new Proj('EPSG:4326', $proj4);

// Your original point
$srcPoint = new Point(2645165.87317, 1132484.62903, $srcProj);

// Create your new point in WGS84 projection
$dstPoint = $proj4->transform($dstProj, $srcPoint);
