Photography, a wonderful medium that has great potential to enhance the SEAMONSTER project. This page deals with all projects of the photographic nature.

Uploading Photographs

JoshG 17:04, 17 August 2009 (PDT)

Photos related to the SEAMONSTER project are archived at http://www.seamonsterak.com/gallery/main.php. The gallery is divided into albums (which you should also think of as directories since an album will often contain other albums) that are organized by location. The process for uploading photos to the gallery is pretty straightforward:

1. Login using the link in the upper right-hand corner of the start page (user "seamonster" and the password).
2. Choose an album that makes sense for your photos to be stored under (i.e. Gallery >> Lemon Watershed >> Upper Lemon >> Cairn Relay).
3. Once you have navigated to the right album click on the add album link in the left-hand navigation table.
4. From here you will be need to fill out a name, title, summary, keywords, and description of the album. You can title the album whatever you want but the standard for naming albums in the gallery is YYYYMMDD (since that will also be the path and should be unique).
5. Once you have created the album you should navigate into that album and then click the add items link in the left-hand navigation table.
6. You will be presented with a number of options in the form of tabs: From Web Browser is a good option if you are only adding a few photos (less than 10). If you want to upload a whole slew of pictures then Upload Applet or Windows XP might be your best bet. If you have a Mac with iPhoto it's even easier: just visit http://zwily.com/iphoto and download the plugin. Once you have installed the plugin you will be able to export photos to Gallery from inside iPhoto.

Geotagging

A geotagged photo (a digital photograph with latitude, longitude, and altitude encoded in it's EXIF tag) is very useful in a geospatially-oriented project like SEAMONSTER. Geotagged photos can be exported as points into programs like Google Earth and Virtual Earth. For an example of how we've used this see Cal:18.9.2008.


A number of items are available for use in geotagging photographs. A few cameras, such as the 8M pixel Ricoh 500se for ~$600, have integrated GPS units. It does not appear that at this point in time there are very many of these cameras available. Quite a few products seem available for post process tagging of photographs with GPS coordinates.

Sony came out with the GPS-CS1KA, $150, a small GPS unit which records ones tracks during their photo escapade. Included software then uses the time stamp applied by the camera to each photograph to reference it to a position along the track line. Reviews for this product are mixed, with 13 customers on Amazon averaging out to 3.5/5. Often cited is the problem that the unit has with locking onto satellites in urban areas or in areas without a good southern view.

The ATP Photo Finder, which day viewed Jan 2008, is similar to the Sony unit in that it is an external gps device which codes photographs with GPS data by matching the time stamps. This unit, however, allows users to simply plug their memory card into the internal card reader and the unit will automatically tag the photos so long as they are shot in JPEG format. The internal card reader supports SD/MMC/MS formats, though an external reader can be plugged into the units via a USB port which will allow XD/CF and other formats to be read. One reviewer reported having quite the difficulty in getting the external card reader to pull photos off of a CF card and ultimately had to dump the photos to a SD card, abandoning the external card reader. The Gadgeteer reviewer also noted that the unit will shut down if it looses a signal for five minutes and that the unit checks and records its location every five minutes. Such a low sampling rate could prove to be an issue when taking photos from the air, as 5 minute could find you over an entirely different part of the icefield/watershed. Perhaps this could be change, however, the unit does not seem all that customizable... The unit runs about $90.

We use the Blue2CAN by Red Hen Systems ($279): an innovative little gadget that mounts directly to the 10-pin slot on the front of many high end cameras (such as Nikon D200, D2x, etc) and which communicates via bluetooth with a bluetooth-enabled GPS device. The Blue2CAN will automatically embed within the metadata of the JPEG or RAW files the lat/long as recorded by the gps unit. The unit got high reviews by the Nikonian (#34). The Blue2CAN is capable of communicating with a GPS unit up to 15m away and evidently draws only limited power from the camera battery. With every thing turned on the reviewer was able to get 3 hours out of the camera battery, in comparison to 2.5 from a GPS unit that was hot-shoed into the camera. The unit was reviewed using the Lite-in LGSF2000 GPS unit as recommended by Red Hen, however, any bluetooth enabled GPS unit will work. Red Hen recommends the following GPS units, available at (http://www.buygpsnow.com/bluetooth-gps_9.aspx): GlobalSat BT-338 ($199/sale$59), Wintec WBT-201, Holux GPSlim 240 ($160/sale$64), Lite-In LGSF2000, Lite-In LGSF3000, Emtac S3 ($130/sale$75).

Units have also been developed which hook into the hotshoe of digital SLR cameras. The Jobo Photo GPS is one example of this type of technology. It is unclear whether the unit auto tags the photographs or whether it is necessary to post process.
