They used to use Digital Globe’s QuickBird They are now using the new GeoEyeħ Resolution & Zoom Most land areas are covered in satellite imagery with a resolution of about 15 m per pixel Google is actively replacing this base imagery with higher resolution l=, &cbp=12, ,0, &ie=UTF8&om=1&panoid=DK9 Dj8cynpLwgcof7otkBA&ll=, &spn=0, &z=13 When following directions, you can use street view to see what each step/ stop will look like – no more getting lost! Google Maps Navigation for Android 2.0 It’s connected to the internet The app is freeĤ How does NASA’s satellite tracking work?įun fact: there are over 8,000 artificial objects orbiting Earth-over 2,500 of these are satellites (the rest are orbital debris) There are two types of JAVA applets in which you can view satellites: J-track & J-pass This technology allows for live 3D snapshotsĥ How does Google Earth get their images? The full constellation was completed on March 9th, 1994. GPS receivers use triangulation of the GPS satellites' navigational signals to determine their location. GPS employs 24 spacecrafts, placed in 6 orbit planes. Since then, it has become an asset for civilian applications & industries around the globe. Department of Defense for the navigation needs of the military. Saving more placemarks, polygons, and paths to my places, directly affect the performance of the software.2 What is GPS? Global Positioning Program (GPS) was developed by the U.S. For example, QGIS provides a plugin called ‘Send2GE’, which is linked with Google Earth Pro. Further, this software is integrated with other spatial mapping software like ArcGIS & QGIS. This supports to import of various types of data formats including ESRI shapefile, Geo TIFF, kml, and images that are commonly used by spatial analysts. For landform mapping also I’m using this software to identify some physical features like escarpments, ridges, isolated hillocks, and slope types using the terrain option.
In that case, I’m using Google Earth Pro to identify land use categories and their changes using historical imageries. As a planner, I’m doing land use and landform mapping to identify hazard-prone locations. With time, I have used Google Earth Pro for various purposes. My very first experience was identifying the locations using the search option. Currently, some countries are having 3D building facilities too. Further, this software is having a facility to generate elevation profiles by adding two points to a path. For example, it provides a street view imagery of most parts of the world and users can have a real feeling about the place. Google Earth Pro consists of several key features that are really helpful for spatial analysts and planners to understand a particular location.
I’m using Google Earth Pro for more than two years.
We can have virtual visits to places where we have never been before. This software is a really good platform to understand the places.
