• Hashtag= #earthtiles Background
    Mapquest's open aerial tiles have proven extremely popular with web developers for exposing satellite imagery of the earth in Leaflet, OpenLayers, and other mapping libraries. Tiles are a popular way to distribute a large amount of geo imagery that can be put in to a standard map (for instance, the front page of spaceappschallenge.org is a Leaflet map!

    Functional Description
    Take global imagery data from Landsat, EOS, Terra, and other missions and turn them in to imagery tiles that can be used in an open source street map. This would enable incredible amounts of visualization and contextual data narration to occur, especially if such tiles were able to be updated on a regular basis as new data is released.

    Ideally, these tiles would be hosted on a CDN that would allow developers to pull directly from the source.


    • MODIS


      MODIS (or Moderate Resolution Imaging Spectroradiometer) is a key instrument aboard the Terra (EOS AM) and Aqua (EOS PM) satellites. Terra's orbit around the Earth is timed so that it passes from north to south across the equator in the morning, while Aqua passes south to north over the equator in the afternoon. Terra MODIS and Aqua MODIS are viewing the entire Earth's surface every 1 to 2 days, acquiring data in 36 spectral bands, or groups of wavelengths (see MODIS Technical Specifications). These data will improve our understanding of global dynamics and processes occurring on the land, in the oceans, and in the lower atmosphere. MODIS is playing a vital role in the development of validated, global, interactive Earth system models able to predict global change accurately enough to assist policy makers in making sound decisions concerning the protection of our environment.

    • Landsat Data


      For 39 years, the Landsat program has collected spectral information from Earth’s surface, creating a historical archive unmatched in quality, detail, coverage, and length.

      Landsat sensors have a moderate spatial-resolution. You cannot see individual houses on a Landsat image, but you can see large man-made objects such as highways. This is an important spatial resolution because it is coarse enough for global coverage, yet detailed enough to characterize human-scale processes such as urban growth.

    • Earth Observing System


      The Earth Observing System (EOS) is a coordinated series of polar-orbiting and low inclination satellites for long-term global observations of the land surface, biosphere, solid Earth, atmosphere, and oceans. EOS is a major component of the Earth Science Division of NASA’s Science Mission Directorate. EOS enables an improved understanding of the Earth as an integrated system. The EOS Project Science Office (EOSPSO) is committed to bringing program information and resources to program scientists and the general public alike.

      Converting NASA Landsat data and serving it through WMS service. Ability for ondemand images band selection. Visit Project

    • earth-tile-creator

      We aim to create a command line utility to make it easy to download landsat/MODIS/EOS data for a given bounding box and time range and create geotiffs, tiles, and possibly other raster outputs. Visit Project

    • GeoPuzzle

      GeoPuzzle is a project we created to tackle the Earthtiles project - converting NASA satellite imagery into tiles that could be used for map creation (via methods like Openlayers and Leaflet). It doesn't stop there however, we're also looking into building an actual map using Openlayers with the... Visit Project

    • Earth_Tiles-Rome

      The leading idea that has guided the project was to create a WMS server based on the Open Source software server "GeoServer". This WMS should expose satellite imagery acquired from Landsat, EOS and Terra missions in web and mobile applications using Leaflet or OpenLayers library. The WMS is av... Visit Project

    • OpenTiles

      Our solution OpenTiles is more of a service than a product. Currently it is a simple implementation demonstrating the 5 main components of the project. We now explain how it would operate at a production scale. Python scripts will take care of the first 3 components. #### 1) Download... Visit Project

    • OpenSpaceMap-Server

      The project is designed to make NASA data more accessible and make the ways to access it simple and easy to use by baking the ability to access NASA data into a popular GIS and Map server.. By making it a fork of a very successful map server it would have all the benefit of wide exposure and sev... Visit Project
