New scholarly journal: Geospatial Applications in Natural Resources

The Arthur Temple College of Forestry and Agriculture, in conjunction with Stephen F. Austin State University, will soon launch a new scholarly journal titled “Journal of Geospatial Applications in Natural Resources”.  The focus of the journal will be to publish via a rapid double-blind peer-review process articles that apply geospatial technology to quantify, qualify, map, monitor, and manage natural resources.

There is no website yet, but I will keep you posted.

Wow! new D3 panel visualization

Mike Bostock's visualizations are glorious. This gives me lots of ideas for visualizing temporal variability across space. I can't embed this here, but I recommend you check it out.

They say: We published a more serious graphic today on drought’s effect on crops, but this was a fun animation we made to sanity-check parsing drought data. NOAA publishes monthly values for the Palmer Drought Severity Index going all the way back to 1895! Dark purple represents extreme drought, while dark green represents extreme moisture. In effect, this is a crazy electric version of Haeyoun Park and Kevin Quealy’s graphic, Drought’s Footprint.

Reservoir levels are still way below average

From our Faith Kearns at the UC Water Institute: https://twitter.com/ucanrwater/status/543501860527550464

As great as this bath has been, we still are way behind normal.

Geo-tagged Tweets in Yosemite


Check out the Geo-tagged tweets in Yosemite Valley.  If you look closely you can see that people are tweeting from the top of Half-Dome, The Mist Trail, Glacier Point, and many parts of Yosemite Valley.  Harnessing this publicly available information may help in understanding what people are thinking and doing in our National Parks.  

All 6 Billion Geo-tagged Tweets are available to view at: https://api.tiles.mapbox.com/v4/enf.c3a2de35/page.html?access_token=pk.eyJ1IjoiZW5mIiwiYSI6IkNJek92bnMifQ.xn2_Uj9RkYTGRuCGg4DXZQ#14/37.7386/-119.5548

NASA NEX wins the 2014 HPCwire Readers' and Editors' Choice Award

Congratulations to the NASA NEX Team! They have won the 2014 HPCwire Readers’ & Editors’ Choice Award for the Best Data-Intensive System (End User focused).  See the article here: NASA Earth Exchange (NEX) Platform supports dozens of data-intensive projects in Earth sciences.

The NASA Earth Exchange (NEX) platform supports dozens of data-intensive projects in Earth sciences, bringing together supercomputers and huge volumes of NASA data, and enabling scientists to test hypotheses and execute modeling/analysis projects at a scale previously out of their reach. NEX-supported applications range from modeling El Niño, creating neighborhood-scale climate projections, assisting in crop water management, and mapping changes in forest structure across North America, to mapping individual tree crowns at continental scale as a foundation for new global science at unprecedented spatial resolution. NEX’s OpenNEX challenge ties in to White House initiatives, including Open Data, Big Data and Climate Data, which advance national goals to address climate change impacts and include competitions and challenges to foster regional innovation.

The GIF has been partnering with NASA NEX, and developing a framework to bring NEX data and analytical capabilities into HOLOS.

Map of open source map resources (as of 2012)

From this great paper I just came across (already much has changed in 2 years, but still cool):

Stefan Steiniger and Andrew J.S. Hunter, 2013. The 2012 free and open source GIS software map – A guide to facilitate research, development, and adoption. Computers, Environment, and Urban Systems. Volume 39: 136–150.

From the paper: "Over the last decade an increasing number of free and open source software projects have been founded that concentrate on developing several types of software for geographic data collection, storage, analysis and visualization. We first identify the drivers of such software projects and identify different types of geographic information software, e.g. desktop GIS, remote sensing software, server GIS etc. We then list the major projects for each software category. Afterwards we discuss the points that should be considered if free and open source software is to be selected for use in business and research, such as software functionality, license types and their restrictions, developer and user community characteristics, etc. Finally possible future developments are addressed."

GIS Day 2014!

Discovering the World Through GIS

November 19, 2014, 5PM-8:30PM

UC Berkeley, Mulford Hall

GIS Day took place in Mulford Hall Wednesday Nov 19th from 5-8:30pm. We had about 200 attendees who participated in workshops, listened to talks, saw posters, and networked with other like-minded GIS-enthusiasts.

Some of the activity at 2014 GIS Day in Mulford Hall

WorldView-3 launched August 13 2014

Worldview-2 has been a very useful sensor; we've used it for some of our wetlands work. On August 13th of this year DigitalGlobe launched WorldView-3 spacecraft. It will provide a 31 cm panchromatic resolution, 1.24 m multispectral resolution, with an average revisit time of <1 day.

From the Digital Globe website:

Introducing WorldView-3, the first multi-payload, super-spectral, high-resolution commercial satellite. Operating at an expected altitude of 617 km, WorldView-3 provides 31 cm panchromatic resolution, 1.24 m multispectral resolution, 3.7 m short-wave infrared resolution, and 30 m CAVIS resolution. WorldView-3 has an average revisit time of <1 day and is capable of collecting up to 680,000 km2 per day, further enhancing the DigitalGlobe collection capacity for more rapid and reliable collection. Launching in 2014, the WorldView-3 system will allow DigitalGlobe to further expand its imagery product offerings.

Here is their spec-sheet.

Sonoma County's historic aerial photographs

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.
 
Sonomaopenspace.maps.arcgis.com

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 left is the image from 1942, on the right is the area in 2011 showing considerable development.
