As part of the massive ongoing effort to map Sonoma County with high-res imagery and lidar, historic imagery of the county was collected and georeferenced. The Sonoma County Agricultural Preservation and Open Space District funded SFEI to mosaic 72 historic aerials taken over Sonoma County by the Department of Defense in 1942. Mark Tukman put together this web service with a image swiping tool showing the combination of the 2011 imagery service and the mosaiced historic imagery.
About the historic imagery: In 1942, the Department of War collected air photos in anticipation of a possible strike. These photos are the earliest complete image set for Sonoma County and give us an unprecedented look at Sonoma County's agriculture and open space prior to the post World War II baby boom.
These images are snaps from the service, both from an area outside Rohnert Park in Sonoma County: on the bottom is the image from 1942, on the top is the area in 2011 showing considerable development.
Take a look at this awesome VTM reshoot from the folks over at Geographic Resource Solutions (GRS), photographed during a recent mapping project of Lassen Volcanic National Park. Yet another great example and an incredible testament to lasting power of the VTM dataset. This particular photo was taken near the Chaos Crags Jumble in Lassen Volcanic National Park. Thanks to Ken Stumpf and GRS for sharing!
In a similar vein I recently stumbled upon another meshing of historical and contemporary photographs. The project features reshoots of the Grand Canyon and resulted in a 2012 book titled: Reconstructing the View: The Grand Canyon Photographs of Mark Klett and Byron Wolfe
Published by University of California Press. You can see a few of the photographer’s recent projects on their website. Historical photos are just the best!
I spent this evening reading the oral history conducted in 1985 by Ann Lange of Albert Wieslander. It is called: California Forester: Mapper of Wildland Vegetation and Soils A. E. Wieslander, and it is a fascinating read. In addition to being a real spitfire and having very clear opinions on things (and people), he also tells this tale about the near loss in 1952 of the vegetation maps. Wieslander had made 23 of his vegetation maps available for publication through the University Press, for production and sale at a cost of $1 each. This was meant to supply funds for the rest of the maps to be published. But that didn't work out as planned.
"Not very many of the maps were sold, even though articles were written to give them publicity. I realized fairly soon that we wouldn't be able to publish any more unless we got additional money someplace.” He was "casually told one day that the University Press had written a letter to the station saying that the maps weren't selling very well, and it wanted to return the quadrangles to the station. They didn't want to handle it anymore.” A forest service employee "told the University Press the station didn't want the maps back and authorized it to dump them. I didn't know anything about this until after it was done. There was nothing I could do about it then. Imagine all these beautiful maps. They didn't even take out one as a sample.”
What!! That is so shortsighted… Anyway read on…
Wies (he refers to himself "Wies" in the interviews) then found out that the University Press couldn't understand the dumping of all those maps and alerted Paul Zinke, Forestry Professor here at Berkeley.
"So Zinke went down and got twenty copies of each of the quadrangles.”
“But, we still had all the original field maps, kept at the experiment station. Just before I retired, I talked with Herbert Mason about all the printed maps having been destroyed and about how it was important to preserve the originals. Researchers could use them. He suggested that the Botany Department set up in the Life Sciences Building a plant geography room. And the main feature of this plant geography room would be the vegetation mapping project. So I moved all the files of maps and sample plots over to the Life Sciences Building. Mason went through the material and found at least a third, maybe more, of the original maps were gone.” Apparently, different national forests had been writing to the station requesting certain maps. Since they didn't have any of the printed maps, originals were sent out, with no record kept of what was sent, or to whom.
This explains why the maps have been scattered across the state, and why it has taken so long to pull them (mostly) together again.
"Anyway, I'm glad that was done. It was a very nice publication, and it gave proper credit to the draftsman who did the beautiful job of drafting, and to the project, and to me. Then Critchfield also worked with James Griffen, of the university, and got out another publication on "The Distribution of Trees in California." It was based on the maps and other data we had." When Wies expressed "concern about these maps and Dr. Critchfield said, "I would like to get them deposited in the Bancroft Library." I don't know whether he did it or not, but that's what he told me.”
Thank goodness that they are back on campus in the Marian Koshland Library, and the whole collection (albeit without the herbarium specimens) will be re-united and available for use./span>
Interesting article from Wired on the recovery of forgotten images from the 1966 Lunar Orbiter 1 mission. The images were taken from a probe orbiting the moon and contain images of the surface of the moon and distant Earth including the first high resolution photographs ever taken from behind the lunar horizon of an Earthrise. The images were recovered from analog data tapes at NASA Ames and have not been seen publicly since the original data from the mission was received in the late 1960s and never at such high resolution. The historical images of Earth are now being used to fill in gaps about Earth's climate in the 1960s. For the full story click here.
Forestry education at UC Berkeley began in 1914 with the “Division of Forestry” in the Department of Agriculture. The Department of Forestry was established in 1939 and the School of Forestry in 1946. Forest Summer Camp, the hallmark of the undergraduate program, began at Quincy, California, in 1915 and moved to Meadow Valley in 1917.
Today, alumni of Cal’s forestry program hold critical positions for the management of 95% of the industrial forestlands in California. The research of our alumni and faculty has grown knowledge in the areas of fire, remote sensing and GIS, ecology, climate change, forest economics, the social sciences, and numerous others.
Over the past 100 years, the Cal Forestry program has had an impact on every dimension of the field, and has produced the profession’s most influential thinkers and doers.
