Etiquetar la geolocalització al digiKam 2.0
Transcrit des de l'article d'en Dmitri Popov, el 24 de març de 2011
La geolocalització no és una característica nova, però en digiKam 2.0 ha estat completament revisada per tal d'agilitar el procés d'etiquetatge geogràfic de les fotos. La nova interfície de geolocalització () disposa de totes les eines d'etiquetatge geogràfic en un sol lloc. La interfície consisteix de tres parts: el plafó del mapa conté un mapa i una barra d'eines amb diverses eines de navegació, sota el plafó del mapa hi ha una llista de les fotos seleccionades, la barra lateral de la dreta mostra la secció activa.
To geotag photos, you need to obtain the geographical coordinates of the place where the photos were taken, and the interface offers several ways to do that. For starters, you can use the mouse to move around the map to locate the desired spot. By default, the interface uses the OpenStreetMap service as its map source, but you can switch to Google Maps using the button below the map pane. If you know the full or partial address of the location, you can use the built-in search feature to find it on the map. Click on the tab, enter the address in the search field, hit the button, and you should see a list of matching results with corresponding pins on the map.
The easiest way to add geographical coordinates to the photos is to drag them from the list onto the desired spot on the map. Alternatively, you can assign the geographical coordinates of a specific search result to the photos. To do this, select the photos in the list, right-click on the desired search result, and pick the item from the context menu.
Once you’ve assigned the geographical coordinates to the photos, press the button to write geotags to the photos.
The interface offers another nifty feature called Reverse Geocoding. This tool can retrieve human-readable locations such as city, street, country, etc. for photos based on their geographical coordinates. The obtained location names can be stored in photos as new tags, so you can easily search for photos taken in a specific country, city, or even street.
One way to put this feature to practical use is to create a dedicated Places tag, and then use reverse geocoding to add place-related sub-tags to it. To do this, create a new tag called Places (you can do this in the sidebar). Select then the desired photos and choose . If the photos are not already geotagged, assign geographical coordinates to them. Switch then to the section, right-click on the tag, and use the available context menu items to add the address elements to the tag (e.g., Country and City). Select all the photos in the list and press the button. You should see the country and city sub-tags (e.g., Germany and Berlin) under Places. Hit then the button, and you are done. Now you can use the sidebar to quickly locate photos taken in a specific country and city.
