Abstract

Various techniques for a method for generating location information for a digital media file. In one implementation, the method may include receiving a first digital media file with location information and a second digital media file without location information, receiving a location hierarchy of the first digital media file, wherein the location hierarchy is determined using a reverse-geocoding algorithm and using the location hierarchy of the first digital media file to determine a location hierarchy of the second digital media file.

Claims

1. A method for generating location information for a digital media file, comprising:

receiving a first digital media file with location information and a second digital media file without location information;

receiving a location hierarchy of the first digital media file, wherein the location hierarchy is determined using a reverse-geocoding algorithm; and

using the location hierarchy of the first digital media file to determine a location hierarchy of the second digital media file.

2. The method of claim 1, further comprising embedding the location hierarchy of the first digital media file into the first digital media file.

3. The method of claim 1, further comprising sending a request to a server to obtain the location hierarchy of the first digital media file.

4. The method of claim 3, wherein the server uses the reverse-geocoding algorithm to determine the location hierarchy.

5. The method of claim 1, further comprising receiving the location information of the first digital media file from a user.

6. The method of claim 5, wherein the location information comprises a level of precision value.

7. The method of claim 1, wherein using the location hierarchy to determine the location hierarchy of the second digital media file comprises:

fixing the first digital media file and the second digital media file to a data structure; and

using the data structure to represent a time space relationship of the first digital media file and the second digital media file.

8. The method of claim 1, wherein using the location hierarchy to determine the location hierarchy of the second digital media file further comprises:

calculating a level of precision for a location of the second digital media file based on a difference in time between when the first digital media file was taken and when the second digital media file was taken; and

using the level of precision to determine the location hierarchy of the second digital media relative to the first digital media.

9. The method of claim 8, wherein using the location hierarchy to determine the location hierarchy of the second digital media file further comprises removing one or more lower levels of the location hierarchy of the first digital media file to determine the location hierarchy of the second digital media file.

10. The method of claim 1, wherein the location hierarchy of the second digital media file is determined using time-based cluster algorithms.

11. The method of claim 1, further comprising embedding the location hierarchy of the second digital media file in the second digital media file.

12. The method of claim 1, further comprising displaying the location hierarchy of the first digital media file and the location hierarchy of the second digital media file.

13. The method of claim 1, wherein the digital media file is a picture file.

14. The method of claim 1, wherein the digital media file is a video file.

15. A computer-readable medium having stored thereon computer-executable instructions which, when executed by a computer, cause the computer to:

receive one or more digital picture files;

identify a first set of digital picture files with location information and a second set of digital picture files without location information;

receive a location hierarchy of each digital picture in the first set of digital picture files;

use the location hierarchy of each digital picture in the first set of digital picture files to determine a location hierarchy of each digital picture in the second set of digital picture files.

18. A computer system, comprising:

a processor; and

a memory comprising program instructions executable by the processor to;

receive a first digital media file with location information, a second digital media file without location information, and a third digital media file with location information;

determine the location information of the second digital media file using the location information of the first digital media file and the location information of the third digital media file.;

receive a first location hierarchy of the second digital media file;

calculate a level of precision for a location of the second digital media file based on a difference in time between when the first digital media file was taken and when the second digital media file was taken, a difference in time between when the third digital media file was taken and when the second digital media file was taken, the level of precision of the first digital media file, the level of precision of the third digital media file, or combination thereof; and

remove one or more lower levels of the location hierarchy of the second digital media file to determine a second location hierarchy of the second digital media file.

16. The computer-readable medium of claim 18, wherein the computer-executable instructions which, when executed by a computer, cause the computer to use the location hierarchy to determine the location hierarchy of each digital picture in the second set of digital picture files comprises computer-executable instructions which, when executed by a computer, cause the computer to:

calculate a level of precision for a location of each digital picture file in the second set of digital picture files based on a difference in time between when the first set of digital picture files were taken and when the second set of digital picture files were taken; and

use the level of precision to determine the location hierarchy of each digital picture file in the second set of digital picture files relative to the first set of digital picture files.

17. The computer-readable medium of claim 18, further comprising computer-executable instructions which, when executed by a computer, cause the computer to embed the location hierarchy of each digital picture file in the second digital picture files in the second set of digital picture files.

19. The computer system of claim 18, wherein the memory further comprises program instructions executable by the processor to embed the location hierarchy of the first digital media file in the first digital media file.

20. The computer system of claim 18, wherein the digital media file is a picture file.
