Cal-Adapt — a new webportal for climate change research

Mapping Data

Cal-Adapt — Exploring California’s Climate Change Research.     A new website was launched today that raises the bar for visualizing and making both state-wide and local mapping possible for a variety of climate and climate parameters. Funded by the California Energy Commission (CEC), it highlights a lot of climate research products by many similarly funded or collaboratively funded climate researchers around the state.

The site and its database was developed by the Geospatial Innovation Facility (GIF) at UC Berkeley, and is both beautiful and nimble to behold. There are interactive maps where you can visualize both spatially and graphically the data and trends for climate like temperature and precipitation as well as snow pack, runoff, sealevel change and wildfire risk from 1950 through two future scenarios to 2090. Much of the raster data can be downloaded in various resolutions– quite a convenience since many are buried in technical sites (one tiny quibble although maybe I am missing something, the resolution of the downloaded data could be better displayed since it’s not immediately apparent).

In addition there is a long list of publications compiled and fully cited with links that focus on climate change issues for the state of California (although many are relevant to other regions as well). A tab for Community promises to be interesting as it has a section on Ask a Climate Expert and Historic Photo Hunt with Coming Soon! posts. The latter is something that promises to post Weislander’s landscape photos from the 1930’s for the public to try to “re-take”, an idea that the Museum of Vertebrate Zoology has been kicking around as we have a similar archive of landscape and habitat photos, of which a tiny fraction have been re-shot for the Grinnell Resurvey Project. I look forward to see their implementation of this citizen-science approach to enhance the VTM Project.

In fact the next few of my posts will be about citizen-science initiatives to harness people power for science…. coming up!


GIS in your pocket – CA Geology

Mapping Data

Integrity Logic’s opening statement says it all: “What if you could hold all of California in the palm of your hand?” They have packed a lot of GIS datasets into an iphone app so you can explore California’s geology, geologic features, hydrology and much more with the usual iphone accessibility to GPS, screen capture etc. Because all the data is locally stored on your device, you are free from the wi-fi or cellular network tether and can use it in the field. The company has similar datasets in separate iphone apps for other states, such as Arizona, Washington, Oregon, Massachusetts, Georgia, Colorado, Minnesota and more.

Thanks, Pascal, for sharing this info!

California Highways: Everything You Ever Wanted To Know Mileposts

California Highways: Everything You Ever Wanted To Know About Numbered Highways. “Dumb as a post” Anyone who slings that insult around hasn’t had to georeference a common locality type in natural history collections, those based on road mileage, specifically referring to milepost on the highways and byways of the US.

Recently the Georef Team had a few based on California county road mile markers: “near 14 mile marker, Carmel Valley Road, Carmel Valley” and “Mile Marker 19.5 on Carmel Valley Rd.” to list just two on the same road.  When out in the field, especially finding a noteworthy roadkill or walking along the road looking for stream confluences, it is convenient to use the landscape and mile markers to record your locality (and the GPS is packed up!), so these are far from rare in some collections. However, it’s a landmark that is not necessarily easy to georeference without a spatial database of mile markers. What? California does not have one!
