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).

Land Change in the Great Plains. This 2015 USGS report, Professional 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/.
TIME feature tracks a changing planet.Users can view successive time-lapse satellite images of their world over 35 years using TIME magazine's new Timelapse project. The imagery comes from Landsat satellites and features Earth's landscape. Viewers can track the effects of climate change, deforestation and the growth of urban areas.
Google's Landsat Viewer. Google's Landsat Annual Timelapse viewer is an interactive video that allows user to pan and zoom anywhere on Earth and view annual mosaics from 1984 to 2012 at the resolution of a Landsat pixel. Users can create custom views of their own areas of interest by zooming and panning to a particular view, and then clicking the "Share this view" button, which produces a custom URL that you can send to anyone. Alternatively, a user can construct URLs by inserting the appropriate latitude, longitude, and zoom level.
