The Wide Open World The Earth is a big place. Techniques in mapping such a large astronomical body have evolved tremendously with in the past 500 years alone.
The Wide Open World From the era of Abraham Ortelius to Gerard Mercator to modern electronic data formats, geographical resources have evolved from being tools of foreign conquest to tools used to advance economic entrepreneurship as well as scholastic achievement. - Cassell and Hiremath
The Wide Open World <ul><li>In the 21 st Century, achieving educational and economic advancements with regard to global mapping involves more than just the skills of a few cartographists. </li></ul><ul><li>A collaborative effort is needed from a variety resources including: </li></ul><ul><li>Systems of Satellites </li></ul>• The Internet <ul><li>Traditional Geographical Resources </li></ul>
G.I.S. Geographic Information System ( G.I.S.) <ul><li>“ A geographic information system (GIS) integrates hardware, software, and data to capture, manage, analyze, and display all forms of geographically referenced information.” </li></ul>http://www.gis.com/whatisgis/
Google earth is a 3D G.I.S. virtual globe program that uses a combination of satellite, panoramic, and aerial imaging resulting in a detail surface map of the earth.
Resources Google Earth uses a wide range of resources to generate rich detailed data of the globe. These resources include: <ul><li>Wikipedia </li></ul><ul><li>The National Geographic Society </li></ul><ul><li>Google Maps </li></ul><ul><li>Satellite photos via the Hubble Space telescope </li></ul>Choice, 2009 <ul><li>Panoramio </li></ul>
Resources The currency and accuracy of Google Earth is dependent upon several factors and resources including : <ul><li>Accuracy of the Collaborative Resources used </li></ul><ul><li>Currency and accuracy of public user input </li></ul><ul><li>Interval upon which Google feels the need to update satellite photos of a region. </li></ul>Google earth June, 2009
Resources Google earth allows users to visually navigate the globe using a wealth of search options. <ul><li>Longitude and Latitude Coordinates </li></ul><ul><li>City, Country, Region </li></ul><ul><li>Businesses, Municipal Institutions, Landmarks </li></ul>
Use/Features The Google earth interface is set up much in the same vein as a internet search engine. Choice, 2009
Use/Features Except in the Google earth, individuals are searching the known global geographical landscape.
Use/Features Google earth several layers of integration including : Earth Mode Sky mode Street View
Earth Mode “ Google earth maps the Earth by using the superimposition of images obtained from satellite imagery and aerial photography ” Wikipedia, 2009
Sky Mode Sky mode uses the archive images compiled between a partnership of the Space Telescope Science Institute (STScI) and the science operations center for the Hubble Space Telescope to display a map of the known universe. Wikipedia, July 2009
