mapping for a changing california
Welcome to the Kellylab blog! We post fun facts and things that catch our eye. Occasionally I wax lyrically about a topic of interest.
Check this out: a site that has historical maps of US counties. It's really cool stepping through time and seeing how the county borders shift and change. Dead simple site, great data. It's a little more interesting for the older states, like Massachusetts, but California has some interesting changes too.
This site has some interesting software approaches for geo-coding public observations in nature. The BioGeomancer Project is a worldwide collaboration of natural history and geospatial data experts. The primary goal of the project is to maximize the quality and quantity of biodiversity data that can be mapped in support of scientific research, planning, conservation, and management. The project promotes discussion, manages geospatial data and data standards, and develops software tools in support of this mission.
Since Google first presented a snapshot of the geoweb at last year’s Where 2.0, it has considerably evolved: more Geo data is published on the web, KML was accepted as an OGC standard and is adopted by a growing number of tools. Join John Hanke, Director of Google Earth & Maps to hear the latest on the evolution of the Geoweb and Google’s effort to organize it and make it universally accessible and useful. In this video from the O’Reilly 2008 Where 2.0 conference, John Hanke demonstrates the latest in Google geo development with Jack Dangemond of ESRI.
Appeals court stops feds plan to log Sierra Nevada forest - The Associated Press /Published 11:37 am PDT Wednesday, May 14, 2008/ A federal appeals court has barred logging in the Sierra Nevada forest. The 9th U.S. Circuit Court of Appeals says the federal government failed to explore other ways to raise money to fight forest fires when it approved a plan to award timber contracts to cut down trees on three sites. The Forest Service says the logging of commercially valuable trees is needed to help pay for thinning of less desirable smaller trees and brush. Environmental groups say the logging plan fails to protect scarce species such as the California spotted owl, martin and Pacific fisher. Attorney General Jerry Brown joined the environmental groups in appealing a lower court decision last year that authorized the government to allow the timber contracts. We'll keep you posted.
Thought some Kelly bloggers might enjoy this video, I believe Brian shows up to Geolunches once and a while.
"Googler Mano Marks demonstrates techniques for using view based refresh (VBR), and other dynamic querying techniques in KML. He show how it works in Google Earth and Google Maps, and talks about server-side coding techniques for generating the KML. And geo developer Brian Hamlin demonstrates a specific application of Dynamic KML, using PostGIS with Google Earth.
This talk is very useful for developers who want to use servers to store data, and show subsets to their users based on what is displayed in their viewport or browser."

Check out this cutie. A fisher from the SNAMP project. Marek was flying over this guy last week.
The USGS announced last week that it will be releasing the entire USGS Landsat Archive at No Charge. This was the message: Imagery for Everyone… Timeline Set to Release Entire USGS Landsat Archive at No Charge. RESTON, VA – The USGS Landsat archive is an unequaled 35-year record of the Earth’s surface that is valuable for a broad range of uses, ranging from climate change science to forest management to emergency response, plus countless other user applications. Under a transition toward a National Land Imaging Program sponsored by the Secretary of the Interior, the USGS is pursuing an aggressive schedule to provide users with electronic access to any Landsat scene held in the USGS-managed national archive of global scenes dating back to Landsat 1, launched in 1972. By February 2009, any archive scene selected by a user – with no restriction on cloud cover – will be processed automatically to a standard product recipe, using such parameters as the Universe Transverse Mercator projection, and staged for electronic retrieval. In addition, newly acquired scenes meeting a cloud cover threshold of 20% or below will be processed to the standard recipe and placed on line for at least six months, after which they will remain available for selection from the archive. Newly acquired, minimally cloudy Landsat 7 Enhanced Thematic Mapper Plus (ETM+) data covering North America and Africa are already being distributed by the USGS over the Internet at no charge, with expansion to full global coverage of incoming Landsat 7 data to be completed by July 2008 (see timeline below). The full archive of historical Landsat 7 ETM+ data acquired by the USGS since launch in 1999 will become available for selection and downloading by the end of September 2008. At that time, all Landsat 7 data purchasing options from the USGS, wherein users pay for on-demand processing to various parameters will be discontinued. By the end of December of 2008, both incoming Landsat 5 Thematic Mapper (TM) data and all Landsat 5 TM data acquired by the USGS since launch (1984) will become available, with all Landsat 4 TM (1982-1985) and Landsat 1-5 Multi-Spectral Scanner (MSS) (1972-1994) data becoming available by the end of January 2009. All Landsat data purchasing options from the USGS will be discontinued by February 2009, once the entire Landsat archive can be accessed at no charge. Landsat scenes can be previewed and downloaded using the USGS Global Visualization Viewer at http://glovis.usgs.gov [under “Select Collection” choose Landsat archive: L7 SLC-off (2003-present)]. Scenes can also be selected using the USGS Earth Explorer tool at http://earthexplorer.usgs.gov [under “Select Your Dataset” choose Landsat Archive: L7 SLC-off (2003-present)].

This is a pretty "flashy" visualization and environmental education tool: http://dsc.discovery.com/guides/discovery-earth-live/discovery-earth-live.html
Via The Map Room: Historical Aerials from historicaerials.com. This is a great site. Look what I found for the campus in 1946. Where's our earthquake trap called Mulford? Obvi this is just a screenshot, haven't got the imagery yet, but the interface is good, and the bay area has tons of old imagery (interested yet, Tim?).
For those of you without at least a passing interest in Martian cartography, Giovanni Schiaparelli was one of the first astronomer's to map Mars using a halfway decent telescope. He drew exceedingly detailed maps of what he saw, depicting massive, linear trenches he called canali. He firmly believed these were too straight to be formed by any natural process, and that they must have been artificially produced by inhuman minds (perhaps even cool and unsympathetic ones). His maps were the state of the art for about 20 years. BibliOdyssey has a wonderful post showing some of Schiaparelli's maps, which are far more beautiful than I had imagined, having previously only seen crude reproductions in 2-tone print. Wonderful stuff. Via The Map Room
The Open Geospatial Consortium announced yesterday that it adopted KML as an OpenGIS standard. OGC is an international standards body, which will now be responsible for the development of KML. Read more on Google LatLong.
"After Google, What?" was the name of a course at the iSchool, but Paul Smith of EveryBlock has asked the same of Google Maps. His answer? An open source web mapping stack. Check out his cool article on A List Apart, "Take Control of Your Maps". If you haven't checked out EveryBlock, do so. Their maps are beautiful. We use a lot of these technologies in the lab and in the GIIF, with the exception of Mapnik, which, to my shame, I've tried and failed to install. Update Some responses: a thread on geowanking including a response from Google evangelist Pam Fox, and discussion and response from the author on ALA (for some reason the post isn't on Technorati yet...).
