My town’s cemetery committee would like to have maps of the grave stones in the three town cemeteries. The late Fletcher Brush cataloged the headstones in each cemetery in the 1990s, and probably made hand drawn maps, but it would be nice to have more official versions. I was asked on Thanksgiving about helping with this mapping, and the next day was beautiful AND had a nice south wind. Flying a kite over the cemetery in the village requires a south wind, and the row of overhanging locust trees along the edge makes late autumn the best season to image all the headstones from above. So I couldn’t resist exploiting what might be one of the last good opportunities to image this site for a long while. Continue reading “Grave images”
The winds have been light this week as the peak colors have been waning and my KAP pack has been poised by the door. I finally had to ignore the “4 mph” reports at WeatherUnderground and WeatherSpark and just go. I went to the hay field south of the Salisbury village where the south wind might push the kite toward the village center. There were some gusty spells that lifted the KAP rig just high enough so that I had to frantically reel it in when calm returned. Attaching and detaching the Picavet in a hurry requires more practice than I have had, and I surpassed my own record for making nasty tangles that included Picavet line, kite line, and alfalfa. At one point I didn’t have time to take off the Picavet as I wildly pulled the line in hand-over-hand, laying it across the field. After untangling (not my favorite thing), I called it a day, disassembled the Fled, and headed back across the field to the pack. When I got there the wind had picked up, so I assembled the Fled, threw it into the air, and had the rig attached when I noticed that I had left the RC transmitter out in the field — out in the huge field of alfalfa and grass that is at places a foot taller than the transmitter (the thing around my neck in the photo above).

A month ago, on May 10, I noticed a wad of dry grass in the birch tree outside my home office window. It was obvious what it was, and a noisy pair of Baltimore orioles soon confirmed that a nest was being constructed. Four days later the nest building seemed to be mostly completed, and I stopped taking photos (click them to enlarge).
The huge kame terraces in my town support a dry-tolerant forest of oaks, beech, and red maple, and as the new leaves emerge it is easier to tell the species apart at a distance. So I have been hoping to fly a kite over the terraces in early May and see if the trees delineated the terraces. The wind was gusty today, but it was supposed to calm down a bit in the afternoon, so I hiked up the hill and launched the nine foot Levitation delta. It was after 6:00 PM when I first triggered the S95 with the Futaba transmitter, and the light was wonderful even if the wind was not. It mostly cooperated until it slowed down enough to send me running upwind barely fast enough to keep the line out of the trees. But I had 900 feet of line out for a while and the camera was well out of the clearing were it could see the tree tops as I never had. Continue reading “Unexpected Panorama”
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.
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”
In Pittsburgh at the Fine International Conference on Gigapixel Imaging for Science in November, there will be a gallery show in the Carnegie Museum of Natural History of huge prints of eight gigapixel images. One of these will be a gigapan of my backyard patch of bergamot surrounded by an unnatural swarm of Ruby-throated Hummingbirds. You can see the gigapan here. The detail included below is about 4% of the area of the entire gigapan which will be printed about six feet wide.
