Built to fly

I awoke this morning to see that not a leaf on the hornbeam was fluttering, and my head fell back to the pillow in dismay. This was a sure sign that I had a new hobby. It was the KAPer’s lament: no wind. I had flown a camera on a kite for two days in a row, and the thought of a calm day was discouraging. But I had started a stitch of yesterday’s aerial panorama before I went to bed, so I got up two hours before Galen had to be at school to check on it.

I built my first KAP rig last week from one of Brooks Leffler’s kits. I have never built anything with servos and dip switches and carbon fiber legs, but I got to use my Dremel tool, so it felt safe. Brooks has designed an elegant system for suspending a camera so that it can point in any direction. The pointing and shutter release are done either at predetermined intervals (autoKAP), or by radio control from the ground. The kit I built had servo motors for both panning and tilting and electronics to automatically point in as many as 76 directions and take photos potentially covering a downward-looking half-spherical view. By replacing the tiny circuit board with a radio receiver, the motors and shutter could be controlled via a transmitter on the ground. It is based on the RC airplane/car/boat/helo standards, so compatible equipment is readily available.

Beyond Prezi

Today I presented some preliminary results of a five-year winter wildlife tracking project my town’s conservation commission has just completed. I was part of a workshop on wildlife connectivity at the Vermont Statewide Conservation Conference in Rutland.

We had some spatial analysis and mapping of the tracking done by Kevin Behm at our county’s regional planning commission, and I wanted to display the mapped results in a compelling way. Google Earth was an obvious candidate for display, but driving Google Earth for a live audience is asking for trouble unless the show is simple. So I used the Movie Maker tool in Google Earth Pro to record three minutes of video highlighting the non-simple results and their context. Continue reading “Beyond Prezi”

Fine Conference

The Fine International Conference on Gigapixel Imaging for Science is winding down and I am really looking forward to the cocktail reception when today’s poster session ends. There is also going to be a raffle for a Gigapan Epic Pro, so there is still much to look forward to.

It has been a real joy to meet lots of people who I knew only through their work online at gigapan.org, many others whose work I hope to know soon, and all the media people who might be incorporating gigapans into their work. It was tremendous fun to see dozens of members of the gigapan community whom I met 18 months ago at my first Fine Outreach for Science Workshop. I have really enjoyed interacting with many people who are more obsessed with gigapixel imaging than I am.

The proceedings papers are now online at http://gigapixelscience.gigapan.org/. A higher resolution PDF of my paper is here. All the presentations were videotaped, so maybe they will be online at some point so I can see the concurrent talks I missed. [UPDATE: Video of my presentation at YouTube.]

The Prezis for my conference talk and the one for my Fine Outreach for Science talk are available online at Prezi.com. These are somewhat sparse in the sense that they are not very self-explanatory, but you might glean something from them if you attended my talks. Here is the motion bubble chart of my gigapan history that I used in the FOFS Workshop. And here is the kml file of Miss Pixie so you can see the Google Earth verification of the map I made of her locations. Here is a pioneering paper by Adam Dick et al. about mapping trees from 360° panoramas.

Thanks to the GigaPan teams for the tremendous effort they put into this event. It was a huge success.

Hot list of gigapans

I have been collecting data about the gigapans I upload to gigapan.org ever since I noticed some unexplained behavior in the View counts and Explore Scores of my first public gigapans. Unlike YouTube, Gigapan does not make archival user data publicly available, so it has to be independently collected. Kilgore661 has been doing a great public service by collecting these data for all gigapans for about three years, and you can explore his archive here and use his nifty graphing tools. I have more than a year’s worth of slightly denser data on my own gigapans. Graphs of these data are wildly revealing about the nature of Explore Scores and the inherent differences among gigapans in how they accumulate Views. I hope to show some of these results at the Fine Outreach for Science Workshop in November.

Unlike Kilgore661, I wasn’t smart enough to use the gigapan API to automate this process, so I have been screen scraping and I just had to stop. The gigapan API is essentially undocumented, but thanks to Miriam at gigapan and Will at Fastie Systems, I now have a tool that collects the pertinent data on all of my gigapans and makes it easy to paste it into Excel. You can see the tool in action here, and learn how to install it on a Web page to fetch the information about your own gigapans.

Gigapans in Google Earth KML tours

I have incorporated some gigapans into Google Earth KML tours and tried three ways to share the tours with others: embedding, KML preview, and downloading. There is not a clear winner. An earlier post has examples of all three methods.

A Google Earth KML (keyhole markup language) file can contain placemarks, paths, and polygons, but it can also include a tour in which recorded navigation movements (flying around) and an audio track can be played back. If a gigapan is included in a KML file which also includes a tour, the user can see where the gigapans are on the landscape and see previews of the gigapans. When the KML tour is stopped, clicking once on the gigapan icon (or the translucent panorama) opens a popup bubble with a thumbnail and the entire description from gigapan.org. Double clicking on the gigapan icon (or translucent panorama) flies you into the panorama just as the “View in Google Earth 4.2+” link at gigapan.org does. The recorded KML tour itself cannot include flying into a gigapan; that part does not seem to play back properly. Continue reading “Gigapans in Google Earth KML tours”

Town Forest KML tour

Below is an embedded Google Earth KML tour which introduces the relationship between the Salisbury Town Forest and some glacial features.

Below is an embedded Google Earth KML tour which introduces the relationship between the Salisbury Town Forest and some glacial features. It includes a two minute flying tour with audio narration. Your computer must have the Google Earth browser plugin installed to play the tour.

Click here to open the KML tour in a new browser tab. Then click the “Play Tour” button (upper right) to start the tour. Your computer must have the Google Earth browser plugin installed to play the tour. (Note: If you enter a gigapan, the “Exit Photo” button is partly hidden under the “Terrain” button. Click the exposed edge of it to exit the gigapan.)

The controls at the lower left of the tour window can be used to stop and start the tour, and when the tour is stopped you can navigate around the landscape and view the photos and gigapans. The links within the gigapan popups are not a good way to view the gigapans. Continue reading “Town Forest KML tour”
