空间坐标系对应EPSG编号

WKT(Well-known text)是一种文本标记语言,用于表示矢量几何对象、空间参照系统及空间参照系统之间的转换。它的二进制表示方式,亦即WKB(well-known binary)则胜于在传输和在数据库中存储相同的信息。该格式由开放地理空间联盟(OGC)制定。

WKB(well-known binary) 是WKT的二进制表示形式,解决了WKT表达方式冗余的问题,便于传输和在数据库中存储相同的信息。

GeoJSON 一种JSON格式的Feature信息输出格式,它便于被JavaScript等脚本语言处理,OpenLayers等地理库便是采用GeoJSON格式。此外,TopoJSON等更精简的扩展格式。

SRID空间参考标识符 是与特定坐标系、容差和分辨率关联的唯一标识符。RID 的填充方式及其所示含义取决于存储数据所用的数据库。目前有多种公认的标准 SRID,例如欧洲石油测绘组 (EPSG) 定义的 SRID。

WKID(Well-known ID)空间参考的ID,常用语ArcGIS二次开发中。表示不同空间参考所对应的ID,例如WKID=4214表示GCS_Beijing_1954这种空间参考,4326代表WGS 84投影。我们常用到的、与中国相关的只有一百多个坐标参考,具体如下表所示:
