how to convert Bridge GPS coordinates

Since Adobe Bridge stupidly enough uses a non standard GPS format

you must convert the Bridge GPS coordinates to any of the standard formats before you can use the GPS location on for instance Google Maps.

 

how to convert Bridge GPS coordinates

to

Degrees and decimal minutes (DMM)

or

Decimal format (DD):

 

Bridge format could be:

57,46.79 N

12,2.4607E

 

It is close to the DMM format which is

57 degrees and 46.79 minutes N and

12 degrees 2.4607 minutes E.

 

Converting to DD (decimal):

57,46.79N  =

57 + 46.79/60  =  57 + 0.7798333  = 57.779833

12,2.4607E  = 

12 + 2.4607/60  = 12 + 0.041011666  =  12.04101167

 

If latitude = S then the decimal latitude value is set to negative.

If longitude = W then the decimal longitude value is set to negative.

I can not state I know how.  Years ago I found Photoshop script that seems to do what you want. However it may be using the Camera EXIF meta data which may not be the bridge data you are referring to. I hardly ever use the bridge.  I forget what the script originally supported.  I may have used a sledge hammer on the script to get it to do what I wanted it to do.  I knew almost nothing about JavaScript and Photoshop Scripting back then. I know just a little more these days.   I can not say I use the script.  But I just downloaded a image of the London Bridge and opened it in Photoshop and ran the script.  A browser window opened with Google Map position  on  the London bridge in Europe not the one in our desert. So it seems like  the code may do what you want.

Thanks JJMack,

 

My post was not a question but a statement of how to convert from the Bridge GPS format.

Useful if you want to convert to a standard GPS format.

 

There are useful scripts for a plugin to show the geolocation of a picture in Bridge (see for instance https://github.com/StigNygaard/Adobe_Bridge_Show_Geo_Location).

Probably doing the same thing as you are showing.

It is very nice, I am using it.

 

But I also want to convert Bridge GPS coordinates to put into my database.

Then you have to do the conversion manually. That's what I meant.

We're a problem resolution focused bunch here...

 

 

/* But I also want to convert Bridge GPS coordinates to put into my database.

Do you wish to import a batch of data, or is it just manually input into the DB one at a time?

 

I'm sure a spreadsheet or some online calculator could help streamline the process, or this could be scripted or ExifTool could be used. 

 

ExifTool reports the GPS info from Bridge, which I believe uses the EXIF GPS format as:

 

[GPS] GPSLatitudeRef : North
[GPS] GPSLatitude : 57 deg 46' 47.40"
[GPS] GPSLongitudeRef : East
[GPS] GPSLongitude : 12 deg 2' 27.64"

 

The following command can reformat this data:

 

 

exiftool -c '%.6f' -GPSPosition 'PATHtoFILEorFOLDER'

 

 

Which will output the data as:

 

GPS Position: 57.779833 N, 12.041012 E

 

Which should be easier to use and can be output to .txt or .csv for a batch of images.

Hi Stephen,

 

I just wanted to give the formula to read the Bridge GPS coordinate to a standard format.

 

But. Exiftool is a strong tool once you learn to use it.

 

Basic problem is that Adobe Bridge uses this format:

[GPS] GPSlatitudeRef: North

[GPS] GPSlatitudeRef: 57,47.758N  (Adobe standard)

and NOT:

[GPS] GPSlatitudeRef: 57deg 47’ 44.056” (GPS standard format)

 

And yes the Exiftool command

exiftool -c '%.6f' -GPSPosition 'PATHtoFILEorFOLDER'

 puts out (on the screen, not changing the information in Bridge) like:

======== E:/_Arkive/Jpgs/IMG_6108.jpg

GPS Position                    : '57.795571' N, '12.048609' E

 

So with Exiftool you can create a list with standard decimal GPS coordinates for Jpeg images in the specified  Bridge folder (that happened to have GPS information), from which list you can cut and paste for instance to a database.

 

Good if you want to use the GPS coordinate with any Map program that does not read the Adobe standard GPS coordinates (is there any?)

 

Thanks for the command!

No need to convert. Just copy and paste from Bridge to Google Maps and delete the commas, leaving a space. For ex: in Bridge: 37,52.8146N and 25,46.6101W paste it in Google: 37 52.8146N and 25 46.6101W
