The Keyhole Markup Language (KML) is an open standard that has been the primary way for users to author and share data visualizations in Google Earth. Google Earth's detailed, world-wide imagery and terrain data provide a rich backdrop for geospatial visualization at multiple scales, from global to local. Recent Advances in Geospatial Visualization with the New Google EarthĪnderson, J. Potential applications of the MaRGEE toolkit include tectonic reconstructions, the movements of glaciers or thrust sheets, and time-based animations of other large- and small-scale geologic processes. However, the inherent spatial distortions that result from the Google Maps Web Mercator projection are not apparent once the transposed elements are saved as a KML file and opened in Google Earth. Due to the imminent deprecation of the Google Earth API and browser plugin, MaRGEE uses a Google Maps interface to facilitate and illustrate the transpositions. The transposition algorithm uses spherical geometry calculations, such as the haversine formula, to accurately reposition groups of points, paths, and polygons on the Google Earth globe without distortion. MaRGEE includes tools to simplify, translate, and rotate elements, add intermediate steps to a transposition, and batch process multiple transpositions. Here we present a new JavaScript web application to 'Move and Rotate Google Earth Elements' (MaRGEE). One significant limitation is the inability to translate or rotate geometrical elements on the Google Earth virtual globe.

However, there remain serious limitations that have hindered its acceptance as a tool for research and education in the geosciences. Google Earth is recognized as a highly effective visualization tool for geospatial information. MaRGEE: Move and Rotate Google Earth Elementsĭordevic, Mladen M. Conclusions revealed that students enjoyed using these applications with laptops and tablets and that the learning process during Geography classes became more interesting. In order to retrieve studentsâ€™ opinions regarding the use of tablets and laptop computers with these two applications, they were asked to respond to a questionnaire after the activities took place. The activities included: navigation with Google Earth/Maps, image capturing techniques, virtual tours, measuring distances or river lengths, identifying relief forms, and locating geographical components of the environment. The research involved 13 students in various gymnasium and high school grades. The research was carried out during the Geography Club seminars organized at â€œRadu Petrescuâ€ High School in the 2013-2014 school year. THE USE OF LAPTOP COMPUTERS, TABLETS AND GOOGLE EARTH/GOOGLE MAPS APPLICATIONS DURING GEOGRAPHY CLUB SEMINARSįull Text Available In the current study, we aim to investigate the use of Google Earth and Google Maps Applications on tablet and laptop computers. Finally, you can export your points, lines, and polygons as KML files and open them in Google Earth or Quantum GIS. You can keep them private or embed them in your website or blog. Your personal maps are saved by Google (in their cloud, meaning you can access them from any computer with an internet connection. It is then possible to mark numerous locations and explore how they relate to each other geographically. As you read about unfamiliar places in historical documents, journal articles or books, you can search for them using Google Maps. Not only is this one of the easiest ways to begin plotting your historical data on a map, but it also has the power of Googleâ€™s search engine. This automates a formerly complex task known as geocoding. It is also possible to import data from a spreadsheet, if you have columns with geographical information (i.e.

In My Maps you can choose between several different base maps (including the standard satellite, terrain, or standard maps and add points, lines and polygons. With a Google Account you can create and edit personal maps by clicking on My Places. Directory of Open Access Journals (Sweden)įull Text Available Google My Maps and Google Earth provide an easy way to start creating digital maps.
