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.
I was there before lunchtime, but the predicted 15 mph winds were not, so I checked out the three huge shagbark hickory trees in the hayfield south of the cemetery. Jackie Devoid told me she collected nuts from these trees as a kid and was tasked with extracting the meats, although she doesn’t remember what her mother did with them. They knew these trees as black walnuts, but those are a lot less common in Addison County than shagbark hickories. I was a little disappointed not to find walnut trees, but the huge strips of loose bark on the old hickories must make great roosting sites for bats. When I got back to the kite at noon, I started to pack up to go home just as a breeze materialized. I was able to get the Fled in the air just as the crew arrived to chop hay.
I flew my minimal rig with a Canon S95 pointed straight down under a Picavet suspension. Once the Fled was high enough there was enough wind to lift a heavier rig, but I had to maneuver around lots of big trees so it was nice to have a more nimble setup. It got high enough to capture the entire cemetery in one shot, but I also brought it down and got several shots over different parts of the cemetery so I would have maximum detail. I used only the center part of these images so the final orthophoto has less distortion, and most of the headstones are viewed from directly overhead. The photos were aligned over the Google Maps image of the area and blended together in Photoshop. The image below is functionally a map — it’s scale and compass directions are known.
The next step is to add a layer over this image with an icon for each grave stone and a code linking to Fletcher’s roster. Fletcher’s roster of the headstones includes row and column data, but I am not sure how he designated rows and columns in this irregular layout. I will have to see if his original maps are available. Below is the current orthophoto embedded from gigapan. Click here to see it full screen where you can zoom in and explore more easily.
Below is an image stitched from nine photos of the larger area north and east of the cemetery. This has about 15% of the resolution of the gigapan version above.

Pretty cool. I see rows and columns. I see dead people.
Might be interesting to pair this with GigaPans of the headstones. I started to do something like this for a cemetery in Ellis, KS (e.g., http://www.gigapan.com/gigapans?query=Ellis+cemetery).
And with a standard target on each headstone, a gigapan could be used to make a map. But the map task is mostly solved. The 19th century inscriptions are fairly hard to read, so careful photography (raking light?) is required to document them. Maybe a clickable map (based on the kite photos) linked to a database with the data from and a photo(s) of each headstone. I’ll get right on that.
