传单:如何显示带有AutoCAD数据的Geojson文件? [英] Leaflet: How to display a Geojson file with AutoCAD data?

问题描述

我试图将geojson文件(从 AutoCAD 文件转换为geojson)显示为第二层(第一层映射 OSM ).

I am tried to display geojson file (converted from AutoCAD file to geojson) as the Second layer (first layer maps OSM).

但是geojson内容占据了整个地图，而不是在特定位置.

But geojson content occupies entire maps, not in a specific location.

如何更改geojson文件中的坐标或如何减小geojson(第二层)的高度和宽度?请在下面的示例geojson文件中找到...

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...

推荐答案

最后，我通过取消投影CRS EPSG3857获得了解决方案，然后同一个geojson文件在Leaflet中正常工作.谢谢..

Finally i got solution by unprojecting CRS EPSG3857 then the same geojson file working fine in leaflet.Thanks..

通过添加，

L.CRS.EPSG3857.unproject(point) // where point is coords.
