在启用了地理标记的 iPhone 上拍摄的 EFIX/JPEG 照片中存储了哪些信息?
我知道其中一些数据可以在 iPhoto 中查看,例如纬度、经度和海拔高度,但是还有更多可用的数据吗?更具体地说,我还想获取图像的方向,这是 EXIF 格式的一部分。或者是否需要启用地理标记以外的其他功能(与指南针有关)?
I know that some of this data is viewable in iPhoto, such as latitude, longitude, and altitude, but is there more than this available? More specifically I am wanting to get the direction of the image as well, which is part of the EXIF format. Or does something other than geotagging need to be enabled (something to do with the compass)?

我建议安装命令行工具
exif
。您可以通过 Mac Ports 以 root 身份执行port install exif
来获取它。以下是我在 iPod Touch 上拍摄的照片中存储的 exif 信息的示例:
我不认为 iPod Touch 在 GPS 方面具有与 iPhone 相同的功能。
看起来 iPhone 也会有数据“GPSImg Direction”,这听起来像你想要的。我认为你不需要做任何特殊的事情来启用它,因为我没有通过搜索找到太多关于这方面的信息。
I suggest installing the command line tool
exif
. You can get it through Mac Ports by executingport install exif
as root.Here's an example of the exif info stored in a photo I took on an iPod Touch:
I don't think the iPod Touch has the same capabilities as an iPhone regarding GPS.
It looks like an iPhone will have the data 'GPSImg Direction' as well, which sounds like what you want. I don't think you have to do anything special to enable it, as I haven't found much info on this through searching.
好的,好消息:)。方向存储在
GPS Img Direction
中。以下是我使用 @rwong 提到的 ExifTool 从 iPhone(打开定位服务和指南针)拍摄的照片中获得的结果。Okay, good news :). The direction is stored in
GPS Img Direction
. Here's what I was able to get from a photo taken from an iphone (with location services and compass turned on) using the ExifTool mentioned by @rwong.您不需要“外部”工具来查看所有 EXIF 信息,使用 iPhone 应用程序 iMetaPhoto 您可以显示所有元信息(EXIF、TIFF、IPTC、GPS、AUXiliary EXIF...)以及(最好的) all)您可以修改其中的大部分,尤其是。您可以修改 GPS ImgDirection。
you don't need an 'external' tool to view all the EXIF-infos, with the iPhone-app iMetaPhoto you can show all metainfos (EXIF, TIFF, IPTC, GPS, AUXiliary EXIF,...) and (the best of all) you can modify the most of them, esp. you can modify GPS ImgDirection.
