你好,我仔细看了一遍L7,功能都很哇塞,但是有一点疑虑,我们公司业务坐标系更多的是cgcs2000,L7是否支持类似CGCS2000这种的坐标系呢 #1512

目前 L7 矢量数据支持 4326,cgcs2000 和4326 基本相同,最终展示只支持3867 墨卡托坐标系。如果要3857展示效果只支持的。如果是cgcs2000 原样不投影转换是不支持的。

请问下,如果我使用leaflet,让L7作为leaflet的一个层,是否就可以通过leaflet来自定义坐标系呢?这样是否会有什么问题?求教。

L7 与leaflet 坐标系不一致,会有偏移想象

可以理解为L7默认坐标系就是4326,各图层不处理坐标系的转换,图层数据的坐标默认按照4326来定位和绘制。
所以只能预先处理数据的非4326坐标系,然后再放入L7中显示?
