By the way, thanks to Volker atMagnalox.netfor the tip on the new layer update – he has been monitoring his newCaribbean 1500 Sailing Cup, so he was quick to notice the new weather layer.

OpenLayers-加载地图数据(Google Map) 除了WMS地图外,OpenLayers可以直接添加Google Map, Microsoft Virtual Earth等地图。 1. 添加google map的key 使用google map的数据需要google map的一个key。OpenLayers的examples里面有一个key,可以直接使用。也可以在https://developers.google.com/maps/signup?hl=zh-cn上...
A geographic coordinate system (GCS) uses a three-dimensional spherical surface to define locations on the earth. A GCS includes an angular unit of measure, a prime meridian, and a datum (based on a spheroid). 可以看出地理坐标系统是球面坐标系统,以经度/维度(通常以十进制度或度分秒(DMS)的形式...
