Data & Maps

The Center for Advanced Land Management Information Technologies (CALMIT) at the University of Nebraska-Lincoln was selected by the USGS as the NebraskaView site and, through this program, provides geospatial data. NebraskaView has developed procedures for archiving and disseminating datasets on this site, as well as linking to data available on the CALMIT Data & Maps website.

Free Data Sources:

Landsat 8 Web Mapping. A number of websites offer innovative capabilities to examine Landsat 8 imagery: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/.

Virtual Nebraska is an on-line archive of satellite imagery and aerial photography that gives users the opportunity to view the State's landscape from unique perspectives (e.g., at infrared or microwave wavelengths). Additionally, this web site offers digital elevation data, learning activities, image-processing tools, historical "looks" at over 600 cities, and examples of how remotely sensed data can be used to solve problems.

Timelapse Images:

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.
