International Map Year

Did you know that it is International Map Year? 2015-2016.  

The International Map Year (IMY) is a worldwide celebration of maps and their unique role in our world. Supported by the United Nations, IMY provides opportunities to demonstrate, follow, and get involved in the art, science and technology of making and using maps and geographic information.

Think about ways in which maps can be integrated into your work!

False precision in the English Lidar release

Great commentary from Martin Isenburgon of LASTools fame on releasing data with false precision. This deals with the new open data release by the Environment Agency in England. So far LiDAR-derived DTM and DSM rasters have been released for 72% of the entire English territory at horizontal resolutions of 50 cm, 1 m, and 2 m. They can be downloaded here. The rasters are distributed as zipped archives of tiles in textual ASC format (*.asc). 

Martin gives us a cautionary tale on how not to release national data. It is not the ASC format that he has problems with, but the vertical precision. He says:

"The vertical resolution ranges from femtometers to attometers. This means that the ASCII numbers that specify the elevation for each grid cell are written down with 15 to 17 digits after the decimal point."

Example heights might be something like: 79.9499969482421875 or 80.23999786376953125. These data should be resolved to about the cm, not attometer, whatever that is. Crazy man!

Data Visualization of WWII

Here in the Kelly Lab we talk a lot about effective ways to visualize data.  How do we show the true weight and impact of those data we work with?  How do we communicate uncertainty?  I think this fellow Neil Halloran did a pretty great job with WWII.  This short video is a combination of visualization and narration.  While effective visualization on its own is ideal, I think the narration offers different avenues of talking about uncertainty in the data.  Check out his video HERE.

Google Earth Engine @ the GIF!

Students, researchers, mappers, and big data enthusiasts took place in an exciting 2 day Google Earth Engine workshop this last week hosted by the GIF and the Google Earth Engine Team. We had an exiting overview of the latest and greatest research adventures from Google by Kelly lab alum Karin Tuxen-Bettman including advances in some of what Google Earth Outreach team is involved in...

As well as new/upcoming ventures
The Earth Engine team led some great tutorials getting people well versed in JavaScript and using the Earth Engine playground, and Earth Engine API. Having beginner and advanced workshop tracks during the two day event allowed for both broad and deep participation from researchers across the Berkeley campus. Take a look at the packed agenda and more here!
We also had a stellar panel of UC Berkeley professor Jeff Chambers and graduate students Sophie Taddeo, Alexander Bryk, and Lisa Kelley who shared an intimate view of how they were using Earth Engine in their research. The panel shared stories of using Earth Engine to evaluate disturbance in tropical forests, map the movement of wetlands, and meandering rivers, as well as looking at agroforestry systems in Indonesia through a socio-ecological lens.
Thanks to Google and the Earth Engine Team for guiding, the GIF for hosting, and all of the participants for engaging in an action packed two days!

Google @ the GIF: Geospatial Technology Workshop

August 20 & 21, 2015

Geospatial Innovation Facility @ Mulford Hall, UC Berkeley

What will you learn?

Led by instructors from Google Earth Outreach and Google Earth Engine, this workshop will teach highly practical tools which can be used to collect, host, analyze, visualize, and publish map data using the power of the cloud. Sessions will include hands-on experience at both beginner and advanced levels using Google Earth Engine, which brings together the world's satellite imagery — trillions of scientific measurements dating back almost 40 years — and makes it available online with tools for scientists, independent researchers, and nations to mine this massive warehouse of data to detect changes, map trends and quantify differences on the Earth's surface. Applications include: detecting deforestation, classifying land cover, estimating forest biomass and carbon, and mapping the world’s roadless areas. Learn more aat http://earthengine.google.org/.

New scholarly open access journal: Remote Sensing in Ecology and Conservation

Remote Sensing in Ecology and Conservation is a new, fully open access journal from Wiley and the Zoological Society of London. The journal will provide a forum for the rapid publication of peer-reviewed, multidisciplinary research from the interface between remote sensing science and ecology and conservation. The journal defines remote sensing in its broadest sense, including data acquisition by hand-held and fixed ground-based sensors, such as camera traps and acoustic recorders, and sensors on airplanes and satellites. The journal's intended audience includes ecologists, conservation scientists, policy makers, managers of terrestrial and aquatic systems, remote sensing scientists, and students. 

Spatial Data Science @ Berkeley May 2015

Bootcamp participants outside historic Mulford HallOur bootcamp on Spatial Data Science has concluded. We had three packed days learning about the concepts, tools and workflow associated with spatial databases, analysis and visualizations. 

Our goal was not to teach a specific suite of tools but rather to teach participants how to develop and refine repeatable and testable workflows for spatial data using common standard programming practices.

On Day 1 we focused on setting up a collaborative virtual data environment through virtual machines, spatial databases (PostgreSQL/PostGIS) with multi-user editing and versioning (GeoGig). We also talked about open data and open standards, and modern data formats and tools (GeoJSON, GDAL).

Analyzing spatial data is the best part! On Day 2 we focused on open analytical tools for spatial data. We focused on one particular class of spatial data analysis: pattern analysis, and used Python (i.e. PySAL, NumPy, PyCharm, iPython Notebook), and R Studio (i.e. raster, sp, maptools, rgdal, shiny) to look at spatial autocorrelation and spatial regression. 

Wait, visualizing spatial data is the best part! Day 3 was dedicated to the web stack, and visualization. We started with web mapping (web stack, HTML/CSS, JavaScript, Leaflet), and then focused on web-based visualizations (D3).  Web mapping is great, and as OpenGeo.org says: “Internet maps appear magical: portals into infinitely large, infinitely deep pools of data. But they aren't magical, they are built of a few standard pieces of technology, and the pieces can be re-arranged and sourced from different places.…Anyone can build an internet map."

All-in-all it was a great time spent with a collection of very interesting mapping professionals from around the country (and Haiti!). Thanks to everyone!

GIS in the Forest - 2015

Sean, Kelly, Alice and Maggi at Forestry CampOnce again members of the Kelly lab trooped into the forest to present GIS and web mapping workshops. We've been doing this since 2012 with Mike Delasaux's great organizational help. This year the workshops were coordinated between IGIS and the GIF, and we had help from Kelly Easterday, Alice Kelly, and Sean Hogan. The Berkeley Forestry Camp is 100 years old, and what fun it is to be in those woods sharing memories of Berkeley Forestry and talking about mapping. Here we are in front of the venerable Baker Forest sign. We of course missed Sam and Stefania!

Wow! New world view Chrome plugin

Kelly turned us on to this plugin from Google. Each time you get a new tab on your browser, you get treated to a new picture of the earth! But, check this one out: 

From Drebkau, Germany. I have no idea what this is an image of - could it be grain fields of some kind, or is it just someone at Google's garage sale carpet? Any thoughts? 

Here is another view of the same area:
