Science On A Sphere

  1. 1. Science on a Sphere<br />Spherical Map Projection in Oregon<br />A fan-boy summary<br />by Sam Churchill<br />
  2. 2. Introduction<br />A globe provides the most accurate representation of the Earth.<br />Every projection distorts at least one aspect- shape, area, distance, or direction<br />
  3. 3. A globe is the only way to represent the earth with constant scale throughout the entire map in all directions.<br />Why Spherical Projection?<br />
  4. 4. Spherical domes are now being used in Oregon. <br />OMSI has Science on a Sphere (right)<br />(<br />Hatfield Marine has Magic Earth<br />(<br />Projection Spheres in Oregon<br />
  5. 5. How does OMSI&apos;s SOS Work?<br />Four Video projectors throw images onto a solid white sphere <br /> Rectangular (equirectangular) maps are broken in 4 sections<br /> One computer synchs the 4 computers/projectors<br />The sphere is a composite of 4 projections on white dome<br />
  6. 6. Map Images<br />SOS pictures are rectangular jpeg or png graphics with a preferred resolution of 4096×2048<br />Animations, such as real-time weather over a week, are MP-4 files, with a preferred resolution of 2048×1024<br />They can be created using FinalCut Pro or Premier<br />
  7. 7. A SphereCast is an SOS presentation done simultaneously at multiple sites by a single presenter, via the Internet. <br />Many sites can receive the SphereCast, but only one site is the host.<br />A SphereCast<br />
  8. 8. The Magic Planet video globe uses video projection from inside and underneath the globe. <br />Oregon State’s College of Oceanic and Atmospheric Sciences (COAS) is use Magic Planet to overlay ocean and atmosphere data sets. <br />Magic Planet at Hatfield<br />
  9. 9. GIS Databases<br />GIS can convert existing databases, which may not yet be in map form, into a variety of maps. <br />Satellite data, census or hydrological tabular data can be converted to maps, as layers of thematic information.<br />Open source resource mapping projects like Oregon Explorer ( and Willamette Basin Explorer ( can make databases, created by government silos, available to everyone.<br />
  10. 10. Many members of the SOS are involved in creating content. Hundreds of datasets are now available for playback.<br />DynamicEarth downloads images such as current weather every 3 hours. NASA’s World Wind Community has more.<br />Add-ons<br />
  11. 11. Newport will be the home of the NOAA&apos;s Marine Operations Center-Pacific. <br />It will be home port to four ships, and also host visiting ships and employ 175 staff members. <br />NOAA expects to be up and running in Newport by July 2011. Will bring in about $19 million annually to community and state. <br />Newport: New Home to NOAA<br />
  12. 12. The University of Washington has received $126 million from NSF to create a cable network on the seafloor. <br />The Ocean Observatories Initiative (OOI) is expected to transform ocean science research and education. Researchers will monitor earthquakes, ocean currents, water chemistry and other ocean processes. <br />A continuous data flow will be provided by hundreds of sensors and integrated by a high voltage, GigE network.<br />Ocean Observatories Initiative<br />
  13. 13. Ocean Observatories: New Opportunities<br />NOAA&apos;s Ocean Observatories will provide high bandwidth data and video imagery in real-time to users around the world<br />UCSD’s Calit2 will manage the cyberinfrastructure while Scripps and the San Diego Supercomputer Center (SDSC) will build the computer network.<br />
  14. 14. Innovative spherical projection methods are now operational in Oregon.<br />Spherical projection might utilize global data sets with Picture in Picture for local data<br />How about an Oceanographic Control Room in Portland?<br />Summary:<br />
