The Change Matters viewer from Esri can show how your area has changed over a given time period, say for instance, from 1988 to 1990. Las Vegas is known for its phenomenal sprawl over the past four decades. Time-lapseimages from the Landsat earth monitoring satellites reveal in false-color, multispectral imagery how urban sprawl has stretched out from Nevada’s “Sin City” over the past four decades.
This latest video was posted by NASA in honor of the 28th anniversary of Landsat 5’s launch on March 1, but the pictures actually go back to 1972, when the Landsat program began.
RapidEye announced that its imagery is being used by the MALAREO project help with malaria control programs in countries in southern Africa. Basically, the satellite is mapping the habitats of mosquitoes, which are generally considered malaria risk area. Funded by the European Commission under FP7, the MALAREO project is a mixed European-African consortium that embodies many years of malaria control expertise with the Global Monitoring for Environment and Security (GMES) EO Capacity.
The MALAREO study area in South Africa, Swaziland and Mozambique is approximately 25,000 square kilometers that RapidEye data provided via the EC/ESA GMES Space Component Data Access (GSC-DA). Over five different days between July 18 and November 10, 2011, the data was gathered with total cloud cover of less than one percent. RSS – Remote Sensing Solutions GmbH, partner in the project consortium, is responsible for data processing and the development of Earth Observation (EO) products.
This past week, 3500 people attended the Esri Federal GIS Conference held in Washington, D.C. Attendees came from virtually every federal agency, nongovernmental organizations (NGOs), GIS companies and other agencies that support federal and state agencies.
Esri president Jack Dangermond kicked off the plenary with a reminder that the world is rapidly changing and we are confronted with new issues such as loss of biodiversity. GIS helps to build intelligence about these issues.
“If we take raw data we can turn it into information by mapping it, that’s why it’s so exciting to look at maps,” said Dangermond. “And now with the dawning of the cloud web world pattern for GIS we’re seeing how we can share this knowledge and create better understanding. GIS drives understanding.”
Some user work was showcased such as the first global dataset of biomass – in Woods Hole, and the relationship between hydrology and biofuels.
Presenters focused on topics such as integration, collaboration and breaking down government silos.
Benjamin D. Hennig at the University of Sheffield will be doing a plenary session at the Population Specialty Group Session at the AAG Annual Meeting in New York this year. He is including a new map of New York City.
A new stable version of GRASS GIS 6.4.2 has been announced by OsGeo. This release fixes bugs found in version 6.4.1 of the program and adds a number of new features. It also includes over 770 updates to the source code since 6.4.1. As a stable release series, the 6.4 line will include long-term support and incremental enhancements while preserving backwards-compatibility with the entire GRASS 6 line.
The new wxPython graphical user interface (wxGUI) has been updated with many new features and tools as Python is a fully supported scripting language, including an updated Python toolkit to simplify the authoring of personal scripts, support for NumPy based array calculations, and a Python application interface (API) for the GRASS C libraries. Additionally, Microsoft Windows support continues to mature. GRASS 6.4.2 debuts ten new modules, a new GUI cartographic composer tool, a new GUI object-oriented modeling environment, an interactive Python shell, and improved infrastructure for installing and managing community supplied add-on modules.
It looks like while the U.S. Defense Department got $2 billion lopped off its R&D budget for next, Darpa is looking good as the White House sees it as putting technological innovation as a key to America’s economic recovery.
“I wasn’t in on the end game negotiations, but I did advocate for preserving R&D/S&T department/government wide in a economic down turn,” says Gen. James Cartwright, the former vice chairman of the Joint Chiefs of Staff who now chairs the defense policy studies program at the Center for Strategic and International Studies. “The reasoning being we will need all the competitive advantage we can muster. The Administration was on board with this and fairly explicit in their support of labs and innovation organizations, the best of which they [the Administration] believe is Darpa.”
This week, a smartphone app will be made available to the citizens in Longview, Texas, where pictures and video can help the city address issues such as potholes that need repairing. Starting yesterday, citizens could log on to their smartphones, take a photo or video of a pothole or other problem in the city, note location and send it to the city.
The underwater volcanic eruption off El Hierro Island continues four months after it began.
Collected on February 10, 2012, this natural color satellite image shows the site of the eruption, near the fishing village of La Restinga. The beautiful aquamarine water indicates high concentrations of volcanic material. Right above the vent a patch of brown water can resemble a turbulent hot tub when the eruption is strongest.
This image was acquired by the Advanced Land Imager (ALI) aboard the Earth Observing-1 (EO-1) satellite. The eruption is just off the southern coast of El Hierro, the youngest of the Canary Islands. El Hierro is about 460 kilometers (290 miles) west of the coast of Morocco and Western Sahara.
According to El Hierro Digital measurements of the sea floor by the Instituto Oceanográfico Español showed that the volcano’s summit is now only 120 meters (390 feet) beneath the ocean surface—10 meters (30 feet) higher than it was in mid January. The height of the erupting cone is about 210 meters (690 feet) from the former ocean bottom, with a total volume over 145 million cubic meters (512 million cubic feet) of new material.
