我在将多边形插入表格结构时遇到问题。我对PostGIS来说比较新,所以我可能会犯这个非常业余的错误。
我的表格设置为"区域"我为我的几何图形添加了一列:
"SELECT AddGeometryColumn(" +
"'public', 'Regions', 'geom', 4326, 'POLYGON', 2" +
");"
根据我的阅读,这将列几何图形设置为接受WGS-83作为我的投影标准。我使用GeoJSON插入我的多边形,因为它对我来说是最简单的选择。这是我的更新声明的一个例子:
UPDATE "Regions"
SET geom = ST_GeomFromGeoJSON(
'{"type":"Polygon","coordinates":[[[-114.017347,51.048005],[-114.014433,51.047927],[-114.005899,51.045381],[-114.001598,51.04509],[-114.001631,51.055109],[-114.01618,51.055062],[-114.016949,51.056508],[-114.016181,51.056511],[-114.01659,51.057251],[-114.017318,51.057237],[-114.018672,51.059928],[-114.020528,51.0593],[-114.023615,51.059311],[-114.021148,51.055829],[-114.018807,51.052583],[-114.017347,51.048005]]]}'
)
WHERE id = 'ab8326c0-beb3-11e4-89eb-b3372c283c42'
我从查询中得到的回复是:
{ [SequelizeDatabaseError: Geometry SRID (0) does not match column SRID (4326)]
name: 'SequelizeDatabaseError',
message: 'Geometry SRID (0) does not match column SRID (4326)',
parent:

file: 'gserialized_typmod.c',

我已将坐标验证为WGS84,但现在我认为该问题与我使用的SRID类型无关。
感谢您的帮助。
