Dan Grover and Mike Z created an interactive data visualization that shows the income distribution along mass transit routes in the Bay Area. 2010 Census median household income for each mass transit station within a census tract for MUNI metro and bus, BART, and CalTrain routes are currently viewable. The project was inspired by The New Yorker’s New York City income distribution viewer for the New York Subway here.

Google recently released the Timelapse project, hosted by Time Magazine, which shows Landsat images from 1984 to today in a timelapse video animation for the entire globe. The viewer allows users to navigate to any spot on the globe via place name and visualize changes on the earth’s surface over the time period captured by Landsat. Google highlights specific areas of interest such as Dubai, Las Vegas, and the Amazon.

From Shasta: along the lines of our VTM photo reshoot project, here is a far more advanced example - the Denali Repeat Photography Project.
he Denali Repeat Photography project has assembled more than 200 photo pairs taken across a large cross-section of Denali from the low-lying black spruce forests to ice fields high in the Alaska Range. What unites these disparate images is that they show repeated views of a single location at different moments in time. The interval separating the pairs of photos varies greatly – from just a few years to longer than a century!
CPAD, the California's Protected Areas Database is releasing a new version. This product maps lands owned in fee by public and nongovernmental organizations for open space purposes, ranging from small neighborhood parks to large wilderness areas.
CPAD 1.9 a major update that corrects many outstanding issues with CPAD holdings data and also has many new additions, particular for urban parks.
CPAD is produced and managed by GreenInfo Network, a 16 year old non-profit organization that supports public interest groups and agencies with geospatial technology. CPAD data development is conducted with Esri ArcGIS products, supplemented with open source web application tools.

From the BBC. Scientists have developed the first global model that analyses the routes taken by marine invasive species. The researchers examined the movements of cargo ships around the world to identify the hot spots where these aquatic aliens might thrive. The research is published in the Journal Ecology Letters.
Marine species are taken in with ballast water on freighters and wreak havoc in new locations, driving natives to extinction.
There has been a well-documented boom in global shipping over the past 20 years and this has led to growing numbers of species moving via ballast tanks, or by clinging to hulls.
Some ports such as San Francisco and Chesapeake Bay have reported several exotic new species arriving every year. Economic estimates indicate that marine invaders can have huge impacts that last for decades.
Now, scientists from the UK and Germany have developed a model that might help curb these unwanted visitors. They obtained detailed logs from nearly three million voyages that took place in 2007 and 2008. The model combines information such as shipping routes, ship sizes, temperatures and biogeography to come up with local forecasts of invasion probabilities.

The Sierra Nevada Conservancy has just released a new report on System Indicators for Forest Health and Carbon Storage. This fourth report in the System Indicators series focuses on Sierra Nevada forests, and includes indicators related to Forest Health and Biomass/Carbon Storage on forest lands. In addition, this report describes the extent, character, and ownership of forest land in the Sierra Nevada Conservancy (SNC) Region. The lead author on the report is our Susie Kocher, from UC Cooperative Extension, and from SNAMP.

Turning on new satellite instruments is like opening new eyes. This week, the Landsat Data Continuity Mission (LDCM) released its first images of Earth, collected at 1:40 p.m. EDT on March 18. The first image shows the meeting of the Great Plains with the Front Ranges of the Rocky Mountains in Wyoming and Colorado. The natural-color image shows the green coniferous forest of the mountains coming down to the dormant brown plains. The cities of Cheyenne, Fort Collins, Loveland, Longmont, Boulder and Denver string out from north to south. Popcorn clouds dot the plains while more complete cloud cover obscures the mountains.

Kevin and I wrote a blog story for UC's Center for Forestry on Cal-Adapt. We walk through the local tools for a community by focusing on Eureka in Humboldt County. Humboldt County, located in Northwest California, is the southern gateway to the Pacific Northwest. The County is bound on the north by Del Norte County; on the east by Siskiyou and Trinity counties; on the south by Mendocino County and on the west by the Pacific Ocean. The County encompasses 2.3 million acres, 80 percent of which is forestlands, protected redwoods and recreation areas. Humboldt County faces a range of changes to its local climate: temperature, snowpack, fire regimes and sea level. Each of these can be explored with Cal-Adapt Local Snapshot tool.
