Geotographer is a simple app with a simple purpose – to set location information for your online photos using GPS tracks recorded while the photos were taken.
We hope that Geotographer is easy to use and can be learned through simple intuition. However, this user guide may be helpful in teaching the basic steps involved in geotagging your online photo collection.
Before You Can Tag Your Photos
Before you can tag your photos, you must have:
- Recorded a GPS track and saved it as a GPX file
NOTE: Geotographer is not a GPS logging app, so you must use an alternate app for this and be able to export GPX files from this app
- Uploaded the photos that you wish to tag to your Flickr account
Geotographer requires access to the internet in order to communicate with Flickr while retrieving lists of images and while committing geotags. In the Map View, additional network traffic is generated downloading the map information as well as images and thumbnails. Thus, for best results, it is recommended that the app is used with a stable network connection. If you are interrupted due to network unavailability, you will be able to continue working where you left off.
Step by Step
After having started Geotographer for the first time, you must give it access to your Flickr account. Flickr authentication is performed by logging on to the Flickr web site and agreeing to grant Geotographer access to your account.
After the Flickr website is loaded, follow the prompts to log in to Flickr and authorise the application.
Once the authorisation process is complete, you may return to Geotographer by pressing the Back button on your device.
Geotographer will remain logged in to Flickr until you tell it otherwise using the “Log out” button.
Open a GPS Track
Press the “Open” button to browse the file system on your Android device for a suitable file to open.
You may also launch Geotographer from different apps, allowing you to directly open GPX files that have been downloaded or received by e-mail.
After the file has loaded, Geotographer will search your Flickr photostream for photos that match the time range of the GPS track. Geotographer will automatically assign locations to all images that it finds based on the GPS track.
Once the images have been loaded, you may immediately commit the calculated locations to your Flickr photostream. To do so, press the “Commit” button and wait while the geotags are committed.
After all the geotags have been committed, you may press “Visit Flickr” to visit your Flickr site to verify the results of the operation.
Note that the Flickr website will be displayed in an external browser window.
Making Adjustments – the Map View Screen
Before committing your locations to Flickr, you are able to review the images and locations found by Geotographer on a map view. To enter the map view, press the “Review” button after having loaded the GPS track file.
After having finished working in the map view, you may return to the main view by pressing the Back button on your Android Device.
The Map View contains a number of panels, some of which may or may not be initially visible:
- Map (always visible)
- Photo View (initially visible)
- Time Adjust (initially invisible)
The Photo View and Time Adjust panels may be enabled or disabled by pressing the Menu button on the Android device and selecting the relevant option.
The map allows you to visualise the GPS track and the positions of all the photos on it.
You may switch between Map and Satellite modes by pressing the Menu button on the Android device and selecting the relevant option.
The location of each image is indicated with a coloured indicator. If the image is marked for update, it is coloured green, otherwise it is coloured red. The currently selected image is indicated with a red ring.
You may select any image by tapping its indicator on the map.
The photo view displays a gallery of all the images that are located within the GPS track.
If the GPS track contains untracked gaps, the photo view may show images which are not allocated positions. Photos which do have assigned locations are shown with a red base on their frames.
In the photo view, you may mark which images are to be updated on Flickr. As in the map panel, a marked image is indicated with a green indicator, while an unmarked image is indicated with a red indicator. Initially, all photos are marked for update. To enable marking of images, you must first press the Menu button on the Android device and select the “Enable Update Mark” option.
Once marking is enabled, you may change the mark for any image by tapping on it once after it has been selected.
The photo view also allows you to open a dialog showing more detailed information about the image and a higher resolution version of it. To open this dialog, tap on an image for several seconds.
If the time on your Android device was not perfectly synchronised with the time on the camera while taking photos, the locations assigned by Geotographer will not be as accurate as they should be. The Time Adjust panel allows you to specify the time difference between the two devices to allow Geotographer to take it into account.
The Time Adjust panel is initially invisible and must be activated by pressing the Menu button on the Android device and selecting the “Show Time Adjust” option.
The left and right buttons adjust the current time offset by a certain period of time. The direction of these buttons should be seen from the perspective of the images – pressing the Left button will make Geotographer treat all images as having been taken earlier, and pressing the Right button will make Geotographer treat all images as having been taken later. The period of time incremented by each button press varies and is determined by the selector underneath the buttons. By changing this value, you may begin by making large adjustments and then moving on to finer adjustments.
The “More” button provides access to more time adjustment features.
- Reset Time Offset: Resets the time offset to zero.
- Restore Saved Time Offset: Sets the time offset to the last previously saved offset.
- Enter Current Camera Time: Enter the current time on the camera, which can be used to calculate the time difference between the camera and the Android device.
- Enter Photo Time: If the time taken of an image is known, sets the time offset to put that image at the beginning of the GPS track.
- Save Current Time Offset: Saves the current time offset so that it can be restored later.
Finishing in the Map View Screen
Once you are satisfied with the changes made in the Map View screen, you may commit the geotags immediately by pressing the Menu button on your Android device and selecting the relevant option.
If you simply wish to return to the main screen, you may do so by pressing the Back button.
That’s Geotographer explained in a nutshell. We hope that you find Geotographer useful and enjoyable to use.
We are planning many additional features to be added to the app in coming months. At the top of our list is support for additional online image repositories.
