将具有CRS "name"：“urn:OGC:def: GeoJson :OGC:1.3:crs 84”的GeoJson转换为Google /long

Question

目前，我正在寻找一种解决方案，将geojson文件转换为修改google地图上的lat-long，如下所示：

well.geojson:

            }
        }
    ]
}

我尝试像ogr2ogr和任何其他的在线工具一样的工具。我也犯了同样的错误：

使用ogr2ogr

ogr2ogr -f "KML“-overwrite "well.kml”“well.kml 2.well.kml”-T_SRS EPSG:4326

错误：

错误1:纬度1326178.000000无效。有效范围是-90,90。此警告将不再发出任何警告1:经度494022.000000已修改以适应范围-180,180。此警告将不再发出。

Answer 1

最后，我找到了解决问题的办法。根据不同的坐标系或地图投影，坐标系统的转换方式有很多种。

1-使用 https://mygeodata.cloud/cs2cs

这个在线工具允许您插入地理坐标的值对，并将它们转换为不同的坐标系或地图投影。您可以将值对插入标记为“输入坐标对”的文本区域--甚至可以使用来自MS或类似程序的复制/粘贴。该工具接受各种值对的输入格式--只需要一行一对。请参见输入文本区域窗口中的示例。

​

​

2-使用 cs2cs 命令行(注意:我正在使用Ubuntu)

cs2cs在一组输入点上执行源和目标地图坐标系统之间的转换。坐标系统转换可以包括投影坐标和地理坐标之间的转换以及基准面偏移的应用。

cs2cs +proj=utm +zone=48 +a=6377276.345 +b=6356075.41314024 +towgs84=198,881,317,0,0,0,0 +units=m +no_defs +to +proj=longlat +datum=WGS84 +no_defs  source.geojson > target.geojson

示例：转换-坐标与cs2cs

3-使用 Proj4js

Proj4js是一个JavaScript库，用于将点坐标从一个坐标系转换到另一个坐标系，包括数据转换。最初是PROJ.4和GCTCP C的一个端口，它是MetaCRS项目组的一部分。

var firstProjection = '+proj=utm +zone=48 +datum=WGS84 +units=m +no_defs';
var secondProjection = "+proj=longlat +datum=WGS84 +no_defs";
proj4(firstProjection,secondProjection,[494022.0, 1326178.0]);

结果：

[104.94123506418815, 11.999521158195288]

我希望这能帮助那些和我一样面临同样问题的发展。
