Spectral Transformer tool sets for Landsat-8 imagery from Geosage

Landsat-8 captures more than 400 scenes per day, and as of early June 2013 more than 20,000 scenes are already available. New from Geosage, free tools for working with Landsat 8 imagery.

GeoSage has released Spectral Transformer tool sets for Landsat-8 imagery to fill in this gap. The standalone tools are powerful and easy to use, and perform three steps of analyses:

  • Step 1: Simple band combination to make three-band imagery composite
  • Step 2: Adaptive linear and non-linear image stretching to make colorful imagery composite
  • Step 3: Advanced and fast image pan-sharpening to make spatially sharper and colorful composite

The tools specifically target Landsat-8 imagery in GeoTIFF format directly downloaded from the USGS Landsat-8 distribution portals, e.g. GloVis.

Landsat 8, officially began its mission on May 30, 2013

The latest in the Landsat series of Earth observation satellites, Landsat 8, officially began its mission on May 30. The purpose is to extend an unparalleled four-decade record of Earth’s land surface as seen from space.  NASA launched the Landsat Data Continuity Mission satellite on February 11. Since then, NASA mission engineers and scientists, with USGS collaboration, have been putting the satellite through its paces – steering it into its orbit, focusing the instruments, calibrating the detectors, and collecting test images. Now fully mission-certified, the satellite will be transferred to USGS operational control and renamed  Landsat 8. The specs:

The technical capabilities of Landsat 8 move forward in three areas in comparison to Landsat 7:  increased spectral coverage; higher data precision (the ultimate resolution is not changed); and increased quantity of data collection (60% more scenes per day).

First Images Released From Newest Landsat Earth Observation Satellite

Some of the first images released from the USGS from Landsat 8 gives us a look at the Colorado Front Range as well as an amazing view of last summer’s wildfire burn just west of Fort Collins, CO.  About the first images… The natural-color images show the intersection of the United States Great Plains and the Front Range of the Rocky Mountains in Wyoming and Colorado. In the images, green coniferous forests in the mountains stretch down to the brown plains with Denver and other cities strung south to north.   LDCM acquired the images at about 1:40 p.m. EDT March 18. The satellite’s Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS) instruments observed the scene simultaneously. The USGS Earth Resources Observation and Science Center in Sioux Falls, S.D., processed the data.

See more details about the LDCM HERE

The cities of Cheyenne, Fort Collins, Loveland, Longmont, Boulder and Denver string out from north to south. Popcorn clouds dot the plains while more complete cloud cover obscures the mountains.

With Landsat 8 DOI / NASA Partnership to Strengthen STEM Careers

This news on the heel of the launch of the next generation of the LDCM and the continuation of the Landsat program – the satellite is expected to transmit images and data about the Earth within 100 days.

Salazar today  released a new strategy to strengthen and inspire education and careers in (STEM. Interior’s STEM strategic plan is designed to provide a five-year framework for engaging the American public—particularly youth underrepresented in STEM fields—to become scientifically literate stewards of our natural and cultural resources while building a future workforce that fully represents the diversity of America for the 21st century… Interior employs nearly 15,000 scientists and engineers, many of whom will be retiring in the coming decade. By emphasizing fields of study in STEM, the Department is better positioned to fill in these critical gaps.

The five-year STEM plan is available at:

40 Years of Landsat Continues with LDCM Launch Today

Wow, launch day is here already as the Landsat Data Continuity Mission spacecraft takes flight to continue with what may in fact be the greatest space exploration success story of our generation! The Landsat Data Continuity Mission spacecraft is set to launch from Vandenberg Air Force Base today. Liftoff is targeted for 1:02 p.m. EST, the beginning of a 48-minute launch window. This launch will ensure the continuation of the 40 year history of Landsat… awesome!

Video – NASA Continuing Landsat’s 40-Year Legacy With LDCM 8

Indeed, it isn’t called the continuity mission for nothing!! The Landsat Data Continuity Mission (LDCM) is a collaboration between NASA and the U.S. Geological Survey that will continue the Landsat Program’s 40-year data record of monitoring Earth’s landscapes from space. LDCM will expand and improve on that record with observations that advance a wide range of Earth sciences and contribute to the management of agriculture, water and forest resources.

USGS Comments, Mission Accomplished for Landsat 5 After 29 Years

IT seems that like the Eveready Bunny, Landsat 5 just keeps in ticking… however, according to the USGS it may be that time has run its course for Landsat 5 and retirement is now looming near. This from the USGS…  Landsat 5 will be decommissioned over the coming months, bringing to a close the longest-operating Earth observing satellite mission in history.  By any measure, the Landsat 5 mission has been an extraordinary success, providing unprecedented contributions to the global record of land change. The USGS has brought the aging satellite back from the brink of failure on several occasions, but the recent failure of a gyroscope has left no option but to end the mission – See more

USPS Taps LandSat 7 satellite images For Earthscapes Forever stamps

This cool story from the USGS takes me back to my days of stamp collecting… Two images from the Landsat 7 satellite are included in the new U.S Post Office series of 15 Earthscapes Forever stamps. Released October 1 to kick off National Stamp Collecting Month, the stamps vividly portray America’s diverse landscapes as viewed from heights of several hundred feet above the Earth to several hundred miles in space.

The Earthscapes collection presents examples of three broad categories of the way that human actions intersect with the land — natural, agricultural, and urban. Note, As part of the Landsat 40th Anniversary Celebration this summer, the USGS and NASA held an online contest in which more 14,000 people voted on their Top Five favorite Earth as Art images.

USGS Landsat 5 Mission in Jeopardy

Amazing that 27 years after a planned 3 year mission, Landsat 5 is finally running into some technical issues and is no longer acquiring imagery according to the USGS.  This from the USGS… 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.

Instead of continuing to operate until the amplifier fails completely, which could bring the mission to an end, USGS engineers have suspended imaging activities for an initial period of 90 days in order to explore every possible option for restoring satellite-to-ground image transmissions.  FYI, Landsat 8 is scheduled to be launched into orbit in 2013.

PErhaps my all-time favorite Landsat 5 image shared by the USGS – The Selenge River Delta
Sensor: L5 TM – Path/Row: 132/24 – Lat/Long: 51.700/107.000 – Date Posted: 07/05/2011

SAIC Introduces online LANDSAT Imagery Resource

Interesting to see that SAIC has rolled out an online Landsat imagery resource. the company bills it as a web-based processing system delivering custom Landsat imagery directly to the customer desktop. Already openly available by the USGS, the SAIC resource provides value added services using an array of spatial and spectral processing options making the data easier to work with. Processing options enable users to specify:
Scaled Radiances or Top-of-Atmosphere processing levels
Projection, resampling method, and output pixel size
Gap-filling for ETM+ SLC-off scenes
Bands or Multispectral Indices of interest
Output file format
