NEW VTM Reshoot!

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!

Rescuing historic data for modern use: a cautionary tale from the past

An example of a VTM vegetation map, from Shufei LeiWe have been talking recently with the HOLOS project and the IGIS InfoBase project about the need to "rescue" data and to provide frameworks for data synthesis. I present to you a profound example of these needs: the VTM project. We are nearing launch of the new VTM website, in which the maps, plots, and photograph portions of the VTM collection are united and powered by HOLOS, open data, and sharing. The journey from paper collection to digital data has been a long one, with several cases of almost accidental and purposeful destruction. As such it is a cautionary tale about the importance of rescued and shared historical data in ecological and geographical analysis. We owe much to all the people who have contributed to the preservation and digitization of this important collection.

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. 

"The maps then made a trip back to the station, where Dr. William Critchfield used them to write a publication called "The Profiles of California Vegetation”. "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 plot data, plot maps, vegetation maps, and photographs will be re-united and available for use.

Advice on writing a clear scientific paper, from Virgina Dale

Advice on writing a clear scientific paper from Virgina Dale, Editor-in-Chief of the journal, Environmental Management since 2001. She says:

  • Scientific papers are not mystery novels. It is important to present the key results in the abstract of the manuscript and to have the introduction of the paper make clear both the impetus for the study and what is be presented in the manuscript.
  • Authors need to give the greatest attention to the parts of paper most likely to be read. Most people do not read a scientific paper from beginning to end but rather first focus on the title, then the abstract, and next the figures and tables. If the information presented is of interest, then the conclusion will be perused. Only those studies that have particular pertinence to the reader will be read in their entirety.
  • Organization of the material is critical. Almost all scientific papers should follow the standard format: introduction, methods, results, discussion, and conclusion.
  • Authors should check that the methods are complete and that most figures and tables are presented in the results section.
  • Each paragraph should start with a strong topic sentence, which presents the main idea and hence is an overview of what is to come. The concluding sentence should summarize the paragraph and provide a logical flow to the next one.

A nice blast from the past: the map that started it all, from Tim

Forest cover in Cadiz Township, Wisconsin: 1831, 1882, 1902, 1950It is graduation season around Berkeley, which means some time to look forward to the future, and take stock of the past. For me, taking stock of the past happened unexpectedly today when, in cleaning up my desk, I found a print-out of one of Tim De Chant's earlier blog posts from Per Square Mile entitled "The map that started it all" about his early fascination with this map, from John T. Curtis, published in Man's Role in Changing the Face of the Earth. Tim is now senior digital editor at NOVA and editor of NOVA Next, which is very cool.

Tim describes the map documenting a transition from a wild Wisconsin dominated by a deciduous forest to a landscape in which the remaining woodlots are barely visible. This was proto-GIS, as Curtis recreated the scenes from survey data and his own observations, painstakingly piecing together handwritten records of the six-by-six mile township.

This is such a nice entry, and reminds me of many things: past students now gone on to great things, past times reading Man's Role in Changing the Face of the Earth in the 1980s in McCone Hall for an exam in Hooson's class, and my own nascent interest in all things landscape palimpsesty and patterny.

Here is my copy (at right) of the venerable tome, Volume 2, complete with its ridiculous price tag: $6.95! 

I've always been in love with maps, and am fortunate now that my career allows me to learn about them and their uses daily.  Thanks Tim for the reminder!
