Please help me get geolocation working. I'm using geolocation.html for documentation.
My test file has good GPSLatitude and GPSLongitude. I want to test the first example illustrated in geolocation.html.

Trying an args file:
#args file
-api
geolocation
"-geolocation*"
E:\test.jpg

Exiftool replies with all the tags in the test file, but not the Geolocation City, Region etc as shown in the example.

Strait from the command line.
exiftool -api geolocation "-geolocation*" test.jpg
No reply from exiftool using the this command.

* Did you read FAQ #3 and use the command listed there?
* Please use the Code button for exiftool code/output.
 
* Please include your OS, Exiftool version, and type of file you're processing (MP4, JPG, etc).

Thank you Stargeek for the faq referance.  I adjusted the args file code, but see no output from exiftool when using this args file.

Are you using an up to date exiftool?  Also, don't separate the hashtag from the comment text.

The update helped and now I see the expected output.

I'm wondering if there is a command to have exiftool go ahead and write the output to the appropriate location tags.  Using the files GPS info to lookup and write the location tags would save much work.

Writing Geolocation Tags while Geotagging
QuoteGeolocation city, state/province and country tags may be written automatically based on the geotagged GPS position by setting the Geolocate tag to "geotag".

The -geolocate=geotag feature is used if you are geotagging from a GPS track log.  If the file already contains GPS, probably you should use "-geolocate<gpsposition"

- Phil

Edit: Fixed incorrect tag name
...where DIR is the name of a directory/folder containing the images.  On Mac/Linux/PowerShell, use single quotes (') instead of double quotes (") around arguments containing a dollar sign ($).

Ah, good to know **takes notes**

Oops.  Typo at my end.  The tag is called Geolocate.  "Geolocation" is the API option.  I've made that mistake a few times.  I'll fix my previous post.

The -geolocate feature is a dream come true for auto generation of location content.
Thank you Phil.

Please help with writing to specific groups with Geolocate.
I am referencing this example in the Geolocate html document:
exiftool -xmp:iptc:geolocate="paris,fr" test.jpg
This args file writes the location tags with no errors:
-IPTC:geolocate<gpsposition
E:\mySourceFolder\gps clean\IMG_20161228_120612.jpg
-o
e:\myTargetFolder\%f.%e

Using this command, ExifTool returns the error
Quote" Warning: Sorry, xmp:ipctext:Geolocate doesn't exist or isn't writable".

-XMP:ipctExt:geolocate<gpsposition
E:\mySourceFolder\gps clean\IMG_20161228_120612.jpg
-o
e:\myTargetFolder\%f.%e

StarGeek

I think what you want is
-XMP-iptcExt:geolocate<GPSPosition

Please help also with using a config file to access the larger Geolocate database.
I want to use a variable in place of the path to ExifTool.
I am using this config file line in the html documentation for reference:
$Image::ExifTool::Geolocation::geoDir = '/PATH/TO/Geolocation500';
I am hoping to replace '/PATH/TO/ with a variable name.  I'm also unsure of the slash \/ to use for windows. 

The Windows 10 path will be the exiftool_files path created by the Betz install:
QuoteE:\exiftool\exiftool_files\Geolocation500

To illustrate, here is an incorrect config file line. 
$Image::ExifTool::Geolocation::geoDir = @PathToExifTool & '\exiftool_files\Geolocation500';

It's -XMP-iptcExt, not -XMP-ipctExt
