exif中使用了什么CRS?

What CRS is used in exif?

EXIF specify a specific coordinate reference system like the WSG-84吗?

Exif 在名称上使用“GPS”,所以我希望使用 WGS-84。

无论如何,Exif 2012,第 73 页:

GPSMapDatum Indicates the geodetic survey data used by the GPS receiver. If the survey data is restricted to Japan, the value of this tag is 'TOKYO' or 'WGS-84'. If a GPS Info tag is recorded, it is strongly recommended that this tag be recorded.

所以你应该检查那个字段,我希望总是看到 WGS-84.
