I have this workspace to add a geotag to a jpeg, based on a GARMIN glo GPS logger.
I merge the GPS data with the jpeg by the date. When I take a look at the inspector merging seems to go well. But there is no exif information in the created jpeg (no original exif info and no latitude, longitude and altitude info). Anyone can help? I am new to FME.
Best,
J.
how are you merging the GPS coordinates? Are you using the RasterGeoreferencer?

looking at the JPG writer I actually start wondering if it supports writing the lat/lon coordinates. Maybe you should contact Safe support to verify this.
In the meantime, maybe this can help? http://geotag.sourceforge.net/
David
Maybe you need to set the relevant metadata attributes?

Well maybe, he can try manipulate the xml data atop in the jpeg (turn extension to txt and check it out), check out the formatrequirements(http://www.media.mit.edu/pia/Research/deepview/exif.html) ?
He is called J.Wiz ;P, so he just might be able to..
I changed strategy. I'll write the xyz coordinates and the image name in a txt file.
Based on the documentation (new to PythonCaller), I am trying this code
----
import fme
import fmeobjects
# Template Function interface:
def processFeature(feature):
pass
# Template Class Interface:
class FeatureProcessor(object):
def __init__(self):
pass
def input(self,feature):
self.pyoutput(feature)
def close(self):
def writeOrientTxt(feature):
name_1=feature.getAttribute('fme_basename')
x_1 = feature.getAttribute('_X')
y_1 = feature.getAttribute('_y')
z_1 = feature.getAttribute('_z')
with open('E:\\Data\\GARMIN_GLO_GPS_LOGGER\\Export_Orient.txt', 'w') as f:
write_data = f.write(name_1 +','x_1+','+y_1+','+z_1+'\\r\\n')
f.closed
pass

The error I get:
Python Exception <IndentationError>: expected an indented block (<string>, line 18)
line 18 is ->name_1=feature.getAttribute('fme_basename')
Anyone can help?
Hi,
Python differ from many other programming languages in that code indentation carries meaning. Indentation must therefore follow the block levels of the code, which isn't the case for your function "writeOrientTxt".

Can you tell me where I need to change identation?

Hi @jwisb, thanks for your patience.
Writing EXIF tags now available in FME 2018.0 Betas (Build 18254+)
This means any JPEG read into FME containing EXIF tags can be written back out to JPEG without losing the EXIF tags. To do this, add a new JPEG writer to the canvas ensure that Write to EXIF Tags is set to Yes.
If you are using an older workspace you will need to add a new JPEG writer (not just update the writer), this is to ensure that existing JPEG writer settings aren’t overwritten with the upgrade.
FME supports most of the available EXIF Tags, this website lists all EXIF tags. If there is a EXIF tag that isn't supported in FME please add a comment to the EXIF Writer idea indicating which tag you would like support for.
You can also add EXIF tags to any raster format being written out to JPEG by using an AttributeCreator and creating the EXIF tags you would like to add. Add jpeg_exif_ before any of the EXIF tag types and then manually set the attribute data. Example attributes:
