问题 I am wondering how to geotag SVG maps. My search results Geotags are available in metadata formats such as Exif, XMP and GeoTIFF. There is even a geotag for SMS (based on "geo:" URI) But there is no geotags in SVG standard. And not found Exif/XMB/... in SVG (ExifTool does not support SVG) Not found standard to encode GeoLocation within filename (eg: RockwoodRural_geo_50.167958_-97.133185.svg ) As GeoLocation can be embedded in XHTML/HTML, and SVG is also XML-based, thus use one of these

问题 I have researched on how to get location data from images returned from UIImagePickerController camera. However, I think that the easiest way is to get the current location from CLLocationManager at the instant UIImagePickerController captures an image. Is there a way of doing this? Is there a way of listening for the "capturePhoto" event, for example? Just to clarify, the users using my app will likely be moving pretty fast. 回答1: Here's what I'd recommend so you don't track the user's

问题 Working currently with the HTML5 Geolocation and I've tested it on all web browsers and it seems to be working. However when I test the Geolocation on the iPad, it works for the iPad mini all the time, but when I put it on the bigger iPad (iPad 2) the location doesn't seem to work all the time.

问题 It is my understanding that the Post object is now Location-aware. However, I can't seem to find documentation on how to publish location-aware Posts via the Graph API. My app is currently publishing Checkins that reference a Place - but I would like to migrate to location-aware Posts since Places are being deprecated. I understand that Checkins are sticking around, and that they will now reference a Page instead of a Place, but, unless I'm mistaken, the Page ID reference is still mandatory,
