NebraskaView

NebraskaView is Nebraska's state node for AmericaView, a nationwide U.S. Geological Survey (USGS) program that focuses on providing easy, low-cost access to remotely-sensed data and promoting remote sensing education, research and applications. Our mission is to ensure that Nebraskans (e.g., state and local agencies, K-16 educators) make the fullest use of geospatial data products (such as Landsat images, digital aerial photographs, and digital elevation data) and technologies such as geographic information systems (GIS).

Announcements/News

LDCM (Landsat 8)

Landsat 9 Update. Development of the Landsat 9 satellite and its sensors continues with plans for a late 2020 launch. As a general rebuild of Landsat 8, already-established designs and subsystems are being implemented where possible to minimize cost, schedule, and risk. Landsat 9 will carry the Operational Land Imager-2 (OLI-2) and the Thermal Infrared Sensor-2 (TIRS-2), similar to the sensors currently carried on Landsat 8.

Landsat 8 Highlighted in Special Journal Issue. A special issue of the journal Remote Sensing of Environment details the improved capabilities and mission role of Landsat 8. The published papers cover topics from how the instrument’s performance gives higher quality electromagnetic measurements to how its improved geometry allows for the tracking of moving ice sheets.

USGS Landsat Update Check out http://landsat.usgs.gov/mission_headlines2016.php for the latest USGS updates on Landsat operations and data. Recent posts highlight data processing changes and short-term data unavailablity.

Land Change in the Great Plains. This 2015 USGS report, Professionlandsatal Paper 1794-B (http://pubs.usgs.gov/pp/1794/b/pp1794b.pdf) is the second in a four-volume series on the status and trends of the Nation’s land use and land cover, providing an assessment of the rates and causes of land-use and land-cover change in the Great Plains . The assessments of land-use and land-cover trends are conducted on an ecoregion-by-ecoregion basis, and each ecoregion assessment is guided by a nationally consistent study design that includes mapping, statistical methods, field studies, and analysis. This regional assessment describes how (and how fast) land use and land cover are changing, and why.

Landsat 8 Web Mapping. A number of new websites offer innovative capabilities to examine Landsat 8 imagery:A Day of Landsat 8 provides almost real time Landsat 8 imagery thumbprints; Landsat 8 Evolution allows both access to Lansat 8 imagery and the ability to compute a time-series gif animation;Landsat 8 Points of Interest shows locations around the world and highlights different band combinations; Snapsat provides downloads of full size images of a chosen band combination.

Amazon Web Services (AWS) offers Landsat 8 data All Landsat 8 scenes from 2015 are available along with a selection of cloud-free scenes from 2013 and 2014. New Landsat 8 scenes are made available on AWS within hours of production. See http://aws.amazon.com/public-data-sets/landsat/ for more details.

NOAA View - This project from NOAA allows users to explore visualizations of Ocean, Land, Atmosphere, Cryosphere, and Climate datasets. There are multiple subsets and datasets can be displayed, with a basic explanaiton of each, by week, month, and year.

Open-Source Landsat 8 Processing Tools. MapBox has developed a process that allows the user to create an interactive map from Landsat 8 imagery using free open-source image-processing and map-making tools. Step-by-step instructions are available at http://www.mapbox.com/blog/processing-landsat-8/.
