spatialite 支持3857

在向spatialite导入数据的时候,如果数据为web墨卡托投影的话,则数据无法导入,提示参考系不存在,解决办法是执行下面的sql语句 insert into spatialrefsys(srid,authname,authsrid,refsysname,proj4text)
values(3857,'epsg',3857,'Web Mercator','PROJCS["Google Mercator", GEOGCS [ "WGS 84", DATUM ["World Geodetic System 1984 (EPSG ID 6326)", SPHEROID ["WGS 84 (EPSG ID 7030)", 6378137.0, 298.257223563]], PRIMEM [ "Greenwich", 0.000000 ], UNIT ["Decimal Degree", 0.0174532925199433]], PROJECTION ["Popular Visualisation Pseudo-Mercator"], PARAMETER ["Latitudeoforigin", 0.0], PARAMETER ["CentralMeridian", 0.0], PARAMETER ["FalseEasting", 0.0], PARAMETER ["FalseNorthing", 0.0], UNIT ["Meter", 1.0]]')
