Everything You Need to Know about Landsat 8

That's the name of a recent DM article, Everything You Need to Know about Landsat 8. From the article: "It is anticipated that over 400 images per day will be collected, the most ever by any previous Landsat satellite."

From the NASA press release: ""LDCM will be the best Landsat satellite yet launched in terms of the quality and quantity of the data collected by the LDCM sensors," said Jim Irons, LDCM project scientist at Goddard. "OLI and TIRS both employ technological advances that will make the observations more sensitive to the variation across the landscape and to changes in the land surface over time."  OLI will continue observations currently made by Landsat 7 in the visible, near infrared, and shortwave infrared portions of the electromagnetic spectrum. It also will take measurements in two new bands, one to observe high altitude cirrus clouds and one to observe water quality in lakes and shallow coastal oceans as well as aerosols. [...] TIRS will collect data on heat emitted from Earth's surface in two thermal bands, as opposed to the single thermal band on previous Landsat satellites. Observations in the thermal bands are vital to monitoring water consumption, especially in the arid western United States."

Google Geonews: Google Earth for iOS 7 Released, Europe Maps Updated, More Landsat Imagery, London Olympics, and more

Here's the recent Google-related geonews.

From official sources:

  • My iPad 2 invited me to update iOS's Google Earth to version 7: "With today’s release of Google Earth for iOS you can literally fly through breathtaking 3D city landscapes and images and follow virtual tours of places you’ve never been [...] The growing list of 3D cities include Boulder, Boston, Charlotte, Lawrence (Kan.), Long Beach (Ca.), Los Angeles, Portland (Ore.), San Diego, Santa Cruz, Tampa, Tucson, and the San Francisco Bay Area (including the Peninsula and East Bay) as well as Rome, Italy. [...] Also new in this release is a “tour guide” to show you interesting places to explore." This topic is discussed at Slashdot in a story named Google Outs 3D Maps For iOS Ahead of Apple.
  • Google also announced more detailed maps in parts of Europe, Africa and Asia: "And today, we’re launching updated maps of Croatia, Czech Republic, Greece, Ireland, Italy, Lesotho, Macau, Portugal, San Marino, Singapore and Vatican City to do just that."

Landsat 5 Mission in Jeopardy

SS informed us that the USGS reported that the Landsat 5 mission is in jeopardy.

From the USGS: "The U.S. Geological Survey (USGS) has stopped acquiring images from the 27-year-old Landsat 5 Earth observation satellite due to a rapidly degrading electronic component. Landsat 5 was launched in 1984 and designed to last 3 years. The USGS assumed operation of Landsat 5 in 2001 and managed to bring the aging satellite back from the brink of total failure on several occasions following the malfunction of key subsystems. There is now an increasing likelihood that the Landsat 5 mission is nearing its end. [...] For several months, the Landsat flight operations team has been closely tracking the fluctuating performance of an amplifier essential for transmitting land-surface images from the Landsat 5 satellite to ground receiving stations in the U.S. and around the world.  Over the past 10 days, problems with the amplifier have led to drastically reduced image download capabilities, a sign of impending failure. [...] Landsat 8, currently called the Landsat Data Continuity Mission, is now scheduled to be launched in January 2013."

We obviously mentioned Landsat 5 often in the past, including in 2005, 2007 and 2009 when it suffered technical problems, but each time, was able to resume satellite imagery acquisition. This time, it's probable it's really the end of Landsat 5. Here's the Landsat 5 Wikipedia article.

Geonews CatchUp: QGIS vs gvSIG, Landsat 8 Milestone, Shaderlight 2, osmdroid, and too much more

That's probably our biggest "geonews in batch mode" issue ever. That's the price I have to pay for three weeks of holidays! ;-) I tried to keep only the most pertinent geonews. After reading this unusually long entry, you and I are back to being up to date in terms of geonews.
