I could see that the lens was still extended... I was the happy owner of 483 new aerial photos of Otter View Park. November 18, 2011

This time it was the dry umbels of Queen Anne’s lace that I was tossing into the air as I crossed the field. WeatherUnderground.com was reporting only 4-7 mph winds at the golf course, but WeatherSpark.com was predicting 10 mph winds from the west which could easily loft the camera over the marsh. This was the first sunny day in a month with a prediction of steady west winds, and it might be my last chance for above freezing weather and a shot at getting aerial photos of the entire cattail marsh at Otter View Park. So I was disappointed with the plummeting umbels, and soon out of breath from running upwind just to watch the Levitation Delta crash in the grass. On the second try, I ran 100 yards and got it just high enough to find a wind.

I went over to the Adirondacks last Wednesday and came back with 1900 photos. Most of them were taken by my Gigapan imager, and half of those are duplicates that will never again see the light of day. Before I even got to New York, I took 126 handheld photos from the Lake Champlain ferry, 48 of which got stitched into the three-row panorama below of the new Crown Point Bridge, still under construction. Back on August 26, the day the central “network tied arch” was lifted into position, I came to repeat the gigapan I took of the old bridge. But the place was crawling with gawkers, and the men in hard hats would not let me get to the place from which the earlier panorama had been taken. So I left defeated. If you missed it too, you can relive the raising of the arch with the fully archived construction webcams, but you have to click through a lot of photos to get to 3:30 PM on August 26 when the action started.

Aspen seedlings and fireweed in a burned study plot.

While in Alaska in June I visited some mountain treeline study plots we established in 1998 to describe and monitor the population of white spruce at the transition between subalpine forest and alpine tundra. I searched the plots for new spruce seedlings and remeasured the ones that had been previously located and marked. A wildfire burned through some of the plots in 2004, and a new tree species has since established where the organic soil was consumed. Thousands of seedlings of quaking aspen now grow in the plots, and I recorded their number and height in subplots. These are healthy seedlings growing in the tundra where, prior to 2004, the only trees were a few stunted spruce. This invasion will be either a short-lived experiment that ends when the aspens try to grow taller than the winter snowpack, or the start of a novel treeline community. Monitoring these plots will eventually reveal how this plays out, so in the meantime counting and measuring a few things is considered to be science.

The succession of precedence

Google has digitized the text of five million books. The old ones are in the public domain and you can read them online at http://books.google.com/. Most of the more recent ones are still protected by copyright law, but that law did not anticipate the ingenuity at Google. The individual words and phrases in all those books are now in a huge database that anyone can search. Maybe you can’t read every book online, but you can learn how book writers have used the language over the past two centuries at http://ngrams.googlelabs.com/. This allows a very new kind of literary research – answering questions without reading. Although it turns out that some reading is still required.
