<p>Here is an example how to set GPS position using pyexiv2 library. I've tested this script by uploading geotagged image to Panoramio</p> <pre><code>#!/usr/bin/env python import pyexiv2 import fractions from PIL import Image from PIL.ExifTags import TAGS import sys def to_deg(value, loc): if value < 0: loc_value = loc[0] elif value > 0: loc_value = loc[1] else: loc_value = "" abs_value = abs(value) deg = int(abs_value) t1 = (abs_value-deg)*60 min = int(t1) sec = round((t1 - min)* 60, 5) return (deg, min, sec, loc_value) def set_gps_location(file_name, lat, lng): """Adds GPS position as EXIF metadata Keyword arguments: file_name -- image file lat -- latitude (as float) lng -- longitude (as float) """ lat_deg = to_deg(lat, ["S", "N"]) lng_deg = to_deg(lng, ["W", "E"]) print lat_deg print lng_deg # convert decimal coordinates into degrees, munutes and seconds exiv_lat = (pyexiv2.Rational(lat_deg[0]*60+lat_deg[1],60),pyexiv2.Rational(lat_deg[2]*100,6000), pyexiv2.Rational(0, 1)) exiv_lng = (pyexiv2.Rational(lng_deg[0]*60+lng_deg[1],60),pyexiv2.Rational(lng_deg[2]*100,6000), pyexiv2.Rational(0, 1)) exiv_image = pyexiv2.Image(file_name) exiv_image.readMetadata() exif_keys = exiv_image.exifKeys() exiv_image["Exif.GPSInfo.GPSLatitude"] = exiv_lat exiv_image["Exif.GPSInfo.GPSLatitudeRef"] = lat_deg[3] exiv_image["Exif.GPSInfo.GPSLongitude"] = exiv_lng exiv_image["Exif.GPSInfo.GPSLongitudeRef"] = lng_deg[3] exiv_image["Exif.Image.GPSTag"] = 654 exiv_image["Exif.GPSInfo.GPSMapDatum"] = "WGS-84" exiv_image["Exif.GPSInfo.GPSVersionID"] = '2 0 0 0' exiv_image.writeMetadata() set_gps_location(sys.argv[1], float(sys.argv[2]), float(sys.argv[3])) </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
