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:

Kelly Lab SPUR Students Visit Point Reyes National Seashore

Kelly Lab SPUR Students Drew Adamski and Ryan Avery have been participating in lab research all semester.  In particular they have been helping classify trails within the Pacific West's National Parks.  This month we were lucky enough to travel out with them to Point Reyes National Seashore to see some of those trails in person.  We were also lucky enough to spend the day with Chief Ranger Schifsky who was kind enough to talk to us about what issues different trails in the park were facing and which trails seemed to be changing most rapidly.  Chief Schifsky was also kind enough to show us some of the points in the park where the landscape had changed dramatically over time due to fire, restoration projects, or differing management strategies.  Overall it was a really inspiring and informative trip!

Croudsourced view of global agriculture: mapping farm size around the world

From Live Science. Two new maps released Jan. 16 considerably improve estimates of the amount of land farmed in the world — one map reveals the world's agricultural lands to a resolution of 1 kilometer, and the other provides the first look at the sizes of the fields being used for agriculture.

The researchers built the cropland database by combining information from several sources, such as satellite images, regional maps, video and geotagged photos, which were shared with them by groups around the world. Combining all that information would be an almost-impossible task for a handful of scientists to take on, so the team turned the project into a crowdsourced, online game. Volunteers logged into "Cropland Capture" on a computer or a phone and determined whether an image contained cropland or not. Participants were entered into weekly prize drawings.

NLCD released and webinar April 15 2014

These three panels of cyclical data (2001, 2006, 2011) from the National Land Cover Database depict intervals of land cover change in the vicinity of Spring Valley, a suburb of Las Vegas, NV.[Source: USGS] Just released, the latest edition of the nation’s most comprehensive look at land-surface conditions from coast to coast shows the extent of land cover types from forests to urban areas. The National Land Cover Database (NLCD 2011) is made available to the public by the U.S. Geological Survey and partners.

Dividing the lower 48 states into 9 billion geographic cells, the massive database provides consistent information about land conditions at regional to nationwide scales. Collected in repeated five-year cycles, NLCD data is used by resource managers and decision-makers to conduct ecosystem studies, determine spatial patterns of biodiversity, trace indications of climate change, and develop best practices in land management.

Based on Landsat satellite imagery taken in 2011, NLCD 2011 describes the land cover of each 30-meter cell of land in the conterminous United States and identifies which ones have changed since the year 2006. Nearly six such cells — each 98 feet long and wide — would fit on a football field. Land cover is broadly defined as the biophysical pattern of natural vegetation, agriculture, and urban areas. It is shaped by both natural processes and human influences. NLCD 2011 updates the previous database version, NLCD 2006.

Webinar about the release will be Tuesday, April 15, 2014, 2:00 PM Eastern Time: "New Version of the National Land Cover Database - April 4, 2014 Release”

The latest version of the National Land Cover Database (NLCD) for the conterminous United States will be publicly released on April 4, 2014.  NLCD 2011 is the most up-to-date and extensive iteration of the National Land Cover Database, the definitive Landsat-based, 30-meter resolution land cover database for the Nation.  NLCD 2011 products are completely integrated with those of previous versions (2001, 2006), providing a 10-year record of change for the Nation.  Products include 16 classes of land cover, the percent of imperviousness in urban areas, and the percent of tree canopy cover. NLCD is constructed by the 10-member federal interagency Multi-Resolution Land Characteristics (MRLC) Consortium.   This seminar will highlight the new features of NLCD 2011 and the related applicationsCollin Homer, 605-594-2714, homer@usgs.gov)

Clark Labs to Create Cloud-based Land Change Modeler for ArcGIS

Clark Labs was awarded a million dollar grant from Esri to create a cloud-based version of their Land Change Modeler for ArcGIS. Land Change Modeler is suite of tools to assess and predict land change and evaluate the impacts of change and includes REDD (Reducing Emissions from Deforestation and Forest Degradation) tools for modeling the impact of land cover change on carbon emissions. Currently Land Change Modeler is only available in IDRISI and as a software extension for ArcGIS (the latest version is compatible with v10.2). This will make this tool more easily assessable to the wider public and scientific community.

From Clark Labs press release:

"Clark Labs was recently awarded a million dollar grant from Esri to create a cloud-based version of their Land Change Modeler for ArcGIS. Currently, Clark Labs’ extension is for the ArcGIS desktop.

Land Change Modeler for ArcGIS, first released in 2007 with Version 2 released this past month, is a software extension for ArcGIS users, offering a suite of tools to assess and predict land change and evaluate the impacts of such change. Clark Labs recent release includes many significant enhancements. The new version is compatible with ArcGIS Version 10.2

The Land Change Modeler offers an extensive suite of tools for land change research in a simple and automated workflow. It provides a variety of tools for land change analysis and prediction, as well as the impacts of those changes.

The new version release of this fall provides significant enhancements, particularly for its utility for REDD (Reducing Emissions from Deforestation and Forest Degradation). Land Change Modeler now includes functionality for modeling the impact of land cover change on carbon emissions. “Our world is changing rapidly, and technology to efficiently model and predict future land change is vital to addressing global challenges,’ said Jack Dangermond, Esri President. “We’re pleased to award this grant to Clark Labs to jumpstart their effort to utilize and provide rich content through ArcGIS Online.”

The new version also provides more capability for estimating land change impacts on habitat and biodiversity. With the grant from Esri, Clark Labs will be creating a cloud-based implementation of Land Change Modeler for their platform.

Clark Labs and Esri have been business partners for nearly ten years, working collaboratively on GIS research."

Global forest change from Landsat and Google

The video describing the partnership and the product is available now.

A new high-resolution global map of forest loss and gain has been created with the help of Google Earth. The interactive online tool is publicly available and zooms in to a remarkably high level of local detail - a resolution of 30m. Snapshot of Russia here (green = forest, blue = gain, red = loss):

Russia has much forest activity

Results from time-series analysis of 654,178 Landsat images from 2000–2012 characterize forest extent and change. Between 2000 and 2012, according to this analysis, the Earth lost a combined "forest" the size of Mongolia. http://www.bbc.co.uk/news/science-environment-24934790

Here is the abstract from the accompanying paper in Science:

Quantification of global forest change has been lacking despite the recognized importance of forest ecosystem services. In this study, Earth observation satellite data were used to map global forest loss (2.3 million square kilometers) and gain (0.8 million square kilometers) from 2000 to 2012 at a spatial resolution of 30 meters. The tropics were the only climate domain to exhibit a trend, with forest loss increasing by 2101 square kilometers per year. Brazil’s well-documented reduction in deforestation was offset by increasing forest loss in Indonesia, Malaysia, Paraguay, Bolivia, Zambia, Angola, and elsewhere. Intensive forestry practiced within subtropical forests resulted in the highest rates of forest change globally. Boreal forest loss due largely to fire and forestry was second to that in the tropics in absolute and proportional terms. These results depict a globally consistent and locally relevant record of forest change.

Workshop wrap up: Google Earth Higher Education Summit 2013

For three days in late July 2013 Kevin Koy, Executive Director of the GIF and Maggi spent time at Google with 50+ other academics and staff to learn about Google Earth's mapping and outreach tools that leverage cloud computing. The meeting was called Google Earth for Higher Education Summit, and it was jam packed with great information and hands-on workshops. Former Kellylabber Karin Tuxen-Bettman was at the helm, with other very helpful staff (including David Thau - who gave the keynote at last year's ASPRS conference). Google Earth Outreach has been targeting non-profits and K-12 education, and are now increasingly working with higher education, hence the summit. We learned about a number of valuable tools for use in classrooms and workshops, a short summary is here.  

Google Mapping Tools - the familiar and the new

• Google Earth Pro. You all know about this tool, increasing ability to plan, measure and visualize a site, and to make movies and maps and export data.
• Google Maps Engine Lite. This is a free, lite mapping platform to import, style and embed data. Designed to work with small (100 row) spreadsheets.
• Google Maps Engine Platform. The scaleable and secure mapping platform for geographic data hosting, data sharing and map making. streamlines the import of GIS data: you can import shapefiles and imagery. http://mapsengine.google.com.
• Google Earth Engine. Data (40 years of global satellite imagery - Landsat, MODIS, etc.) + methods to analyze (Google's and yours, using python and javascript) + the Cloud make for a fast analytical platform to study a changing earth. http://earthengine.google.org/#intro
• TimeLapse. A new tool showcasing 29 years of Landsat imagery, allows you to script a tour through a part of the earth to highlight change. Features Landsat 4, 5 7 at 30m, with clouds removed, colors normalized with MODIS. http://earthengine.google.org/
• Field Mobile Data Collection. GME goes mobile, using Open Data Kit (ODK) - a way to capture structured data and locate it and analyze after home.
• Google Maps APIs. The way to have more hands-on in map styling and publishing. developers.google.com/maps
• Street View. They have a car in 32 countries, on 7 continents, and are moving into national parks and protected areas. SV is not just for roads anymore. They use trikes, boats, snowmobiles, trolleys; they go underwater and caves, backpacks.

Here are a couple of my first-cuts:

PROBA-V satellite launched May 7

Proba-V’s first image of FranceI haven't used PROBA imagery, but many colleagues in Europe rely on this sensor.

PROBA-V (i.e. "vegetation") was launched May 7. The miniature satellite is designed to map land cover and vegetation growth across the entire planet every two days. The data can be used for alerting authorities to crop failures or monitoring the spread of deserts and deforestation.

Less than a cubic metre in volume, Proba-V is a miniaturised ESA satellite tasked with a full-scale mission: to map land cover and vegetation growth across the entire planet every two days.

Proba-V is flying a lighter but fully functional redesign of the Vegetation imaging instruments previously flown aboard France’s full-sized Spot-4 and Spot-5 satellites, which have been observing Earth since 1998.
