Meadow fire update, burning in Little Yosemite Valley

It's now on Inciweb. The Meadow fire is burning near Yosemite, at the east of Little Yosemite Valley.

From Yosemite NP:

As of 11-9:

The Meadow Fire has progressed rapidly and in multiple directions. In order to maintain the safety of park visitors and allow fire management operations to continue unimpeded, the Superintendent of Yosemite National Park is designating a portion of Yosemite Wilderness as closed. The area will be closed until further notice is given.

As of 11-8:

"Meadow (37 42.738 x 119 30.541 – Mariposa Co., 7,870’, August 16) A fire, that may be a spot fire, from the Meadow lightning-caused fire, was discovered at approximately 12:30 PM, Sunday September 7. The fire is approximately 2,582 acres. It is burning within the Little Yosemite Valley (LYV) on both sides of the Merced River. All trails in the area are closed. Approximately 100 hikers and backpackers were evacuated from the fire area in LYV. The fire is burning in Yosemite Wilderness. The High Sierra Camps were seasonally closed today."

Scott Stephens says it is growing fast. We will keep our eyes on it.

New VTM reshot, from Tim Hanson

This one from Tim Hanson. The caption from the photos (286747. 286748, 286749, 286750) reads:

"Butte County. Panorama looking SW, S. SE and E from Neal Road. Note Juniperus californica in ravine. Woodland grass type of blue oak and digger pines with occasional Ceanothus cuneatus, Arctostaphylos manzanita and Rhus diversiloba."

There is still California juniper in the ravine, including far right of the new photo, which is uncommon in Butte County. The rare Monardella venosa grows in patches of dense clay soil in the flats of the canyon. The Wieslander picture was taken on 6/24/1933 and his picture was taken on 5/3/2011.

That was a long, rolling quake

From Live EarthquakesWe felt the 6.0 quake here in Berkeley as a long, rolling, continual shimmy. Up in Napa it was considerably more than that. Lots of news about lost wine etc. There have been a number of small aftershocks since 3am, we haven't felt them here, but Napa valley is jumping this morning.

New VTM photo reshoots from Joyce - check it!

Joyce Gross is our most avid VTM photography buffs. Here are two new VTM reshoots for our viewing pleasure. Her original post here, and here are all her new photos on CalPhoto.

She says: This was the first VTM photo site I've found that required a hike to get there. Not only was the photo not taken from a road, but it was not taken from a trail. The hike from my car to the site was a little over a mile, but it felt like more. It was all uphill, and we didn't really know where we were going. The first 2/3 of the hike was along a narrow, rocky road (image below). The last third of the hike involved somewhat random wandering over rocks and around bushes towards a view we hoped to see but weren't sure exactly where it was. My Garmin GPS, and Gaia GPS on my iPad, were my friends on this hike, helping us get to the photo location and, especially, helping us get back. Thanks Joyce!

Measuring Development: Energy & Environment

I spoke yesterday at the CEGA-DIME* co-sponsored event: Measuring Development: Energy & Environment.  This was a terrific day of interesting talks, thoughtful conversations and great networking.

This workshop brought together engineers, social scientists, donors, and practitioners to discuss the use of novel measurement tools--including sensors, sensor networks, microsatellite imaging, and other remote sensing technologies--in energy and environment research. 

I presented an "ignite" talk on some of our mapping work and talked about the idea of "Spatial Data Science". There were a number of highlights. Matt Hancher from Google gave a great overview of Google Earth Engine and asked: "What if the micro-satellite imagery revolution works. What will you do with the data?” Great and timely question. Big Spatial Data workshop to the rescue! We heard from people at the Energy Institute at Haas who are looking at smart sensors, iButtons and billing networks to understand energy usage around the world; Ronald Cohen from the Climate Readiness Institute spoke; there was tons of discussion about low earth orbit micro-satellites from Skybox and the Spire company (they monitor AIS beacons on ships yet they also can still find them as they move back and forth through fishing zones and turn off their beacons); there was a great idea from Tony Vodacek from RIT on the need to develop “a remote sensing playbook”: What are the sensors, resolutions, bands that are needed for a particular task?. David Lobell from Stanford highlighted some of his great work in remote sensing of crop yields; and Sol Hsiang from the Goldman School outlined his fascinating work on natural disasters, economies and violence.

Background: Technologies for measuring the adoption and impact of development interventions have seen substantial innovation over the past several years—examples include the use of microsatellite data for mapping weather patterns and agricultural yields, sensors for tracking behavior change, smart meters for recording real-time energy use, continuous emissions monitoring systems for measuring particulate matter, and platforms for smartphone- and tablet-based survey data collection. At the same time, network protocols for data management, visualization, and analysis have drastically improved.

Summer 2014 Wrap Up

What we worked on summer 2014

VTM collection

Like old maps? Have we got a project for you... For more than 10 years now I have been working on and obsessed with the maps and data from the Wieslander Vegetation Type Mapping project. The original collection has been digitized, and both the analog and digital version are finally being reunited under the auspices of HOLOS. Stay tuned for the launch!

Owls and Lidar, and more broadly remote sensing of owl habitat

What is the best way to map owl habitat? Owls need canopy cover, moderate tree sizes, and large residual trees. What is the best way to map these forest characteristics over large scales? We are working with the Forest Service owl biologists to understand how owls use Sierra Nevada forests.

SNAMP

Our nearly 10 year project to establish an adaptive management process in the Sierra Nevada is coming to an end this year. We have learned so much, and are working on our final report that will be shared later this fall.

On the staffing side

We are so happy for Kevin Koy who is leaving the GIF to be the Executive Director of the Berkeley Institute for Data Science. We are actively searching for his replacement. If you are interested, look here.

Google Geo for Higher Education Summit 2014


Just got back from an amazing workshop with the Google Earth Outreach Geo Team and 50+ geospatial educators, researchers, and lab managers! 

In between stealing off on the colorful google bikes  and spending time wandering the amazing Google campus, we engaged each other in discussions of integrating Google tools into higher education and learning and attended workshops introducing the plethora of Google mapping tools.

We had a warm welcome from Brian McClendon (VP of Engineering, Geo at Google, mastermind behind Google Earth, and creator of KML) who gave a great history of the program and the creation of Google Geo and gave an exciting announcement that Google; with the acquisition of Skybox is now taking to the sky with their own satellites in hand (contrary to popular belief, Google has not to this point owned any Satellites).  With this acquisition, near-real live time imagery on Google platforms seems to be closer than ever before.

Rebecca Moore (Engineering Manager, Google Earth Outreach and Earth Engine) also gave a great history of the importance of Google Earth and its transformation over the years highlighting a number of exiting things to come and products not yet released to the public including

1. A new MODIS time-lapse!

From Maggi’s blog post last year on timelapse created from LANDSAT imagery we saw the amazing capabilities to see transformations over time with the click of a button. Now Google will soon release MODIS time-lapse which having a quicker repeat interval will be able to show seasonal changes .

Check out this example here showing fires across the world, and more targeted video here! Awesome!

2. Also great news for those of you tired of the coarse resolution SRTM 90 DEM, Google is currently working to produce a much higher resolution global DEM product…stay tuned!

Throughout the 3 days, I had the opportunity to attend a variety of different workshops and came away absolutely jazzed! See below for a summary of the latest and greatest from the Google Geo team with links attached if you’re interested and want more information….. Also stay tuned for some of my renderings and products from the training!

Google’s “Ecosystem” of Technologies

Mapping:

Google Maps Engine (GME): hosting data and publishing maps online, and ability to build applications and connect Google’s data with your own.

GME Pro&Lite: simple map making in the cloud, visualize, draw, import a csv, and style your maps

Maps Gallery: A new way for organizations and public institutions to publish and share their maps online through the Google maps Engine

Google Crisis Map: a map interface initially used for emergency alerts, however it’s not entirely dedicated to crisis as you can easily integrate and create your own map mashup and community awareness map here

Maps Engine API (application program interface): to access Maps Engine data, create a new applications utilizing the data, stylize and create beautiful maps

Analysis

Google Earth Engine: (EE), Google’s geospatial analysis platform. Earth Engine 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.

Earth Engine API (application programming interface) provides the ability to create your own algorithms to process raster and vector imagery.

Timelapse builds on Earth Engine to show decades of planetary change, both man-made and natural

Data Collection

Streetview: in Google Maps and Earth provides over five millions miles of interactive 360-degree panoramas across all seven continents; it’s the closest thing to teleportation, allowing teachers and students to virtually walk almost anywhere they dream of going. Street View began on the roads, but new technologies like theTrekker backpack or an underwater rig can take you almost everywhere.

                -Treks: Street view special collections (museums, up a mountain,etc..)

                -Views: streetview imagery crowd-sourced from user generated 360 degree photospheres. You can now connect your photospheres to create your own street view using constellations

Mobile Data Collection using Open Data Kit allows you to collect field data, such as text, photos/videos, and GPS location from an Android device where there's no internet connection and then publish that data to the web when you're back online. You can then export your data into Google Earth Engine for mapping and Google Fusion Tables for graphing, mapping and visualization. 

Visualization/ Story Telling

Tour Builder: Tour Builder is a new way to show people the places you've visited and the experiences you had along the way using Google Earth. It lets you pick the locations right on the map, add in photos, text, and video, and then share your creation. The new geo-enabled Powerpoint!

 

Thanks to Maggi for the opportunity to attend and the talented, enthusiastic Google Geo staff (including: Karin Tuxen-Bettman, John Bailey, David Thau, Christiaan Adams, and all the other workshop leads and those behind the scenes!) for developing such an action packed workshop!

Find related research based on location and biophysical attributes: Map search

Check it out: another way to search for research. JournalMap is a scientific literature search engine that empowers you to find relevant research based on location and biophysical attributes combined with traditional keyword searches. It works ok, I found one of my papers, not others. But the interface it quick and intuitive.
