![]() Google Earth Pro allows its users to use advanced measurement tools to measure land developments, parking lots, etc. However, there are important differences.įirst, let’s start with Google Earth Pro’s additional features. With that in mind, you can use Google Earth Pro for almost everything that you would use Google Earth for. The Pro version of the software has all the same basic features as Google Earth. Luckily, since 2015, Google Earth has become free to use for anyone. ![]() This is exactly the reason why Google Earth Pro used to cost $399 annually. Simply put, Google Earth Pro is a level up from Google Earth as it is packed with more features that can be used for professional purposes. This software allows its users to both analyze and capture Earth’s geographical data. Google Earth Pro is a geospatial program that also displays a 3D model of Earth. That way, you can save a lot of space on your device.Īs a cherry on top, all of this is completely free. Nowadays, you can use the browser version of this program that contains all the features mentioned above. Previously, users needed to download Google Earth on their computers to enjoy all of its features. Google Earth is available on most popular operating systems, including Windows, Android, Linux, iOS, and macOS. The information for this feature has been gathered from oceanographers and leading scientists. This feature supports more than 20 content layers. Since 2009, Google Earth users can “dive” into the ocean by zooming in below the surface. This feature displays a 360-degree street-level, panoramic photos. Since April 2018, people can use Google Earth to inspect whatever streets they like as Google Street View is fully integrated into Google Earth. The change started with larger cities and gradually spread to other places around the globe. Many updates later, Google announced that they will be replacing their previous 3D models with auto-generated 3D meshes. They were then uploaded to Google Earth using 3D Warehouse. In this software’s initial versions, the buildings were primarily made using programs for 3D modeling, such as SketchUp. Google Earth can show lifelike 3D building, street, and vegetation models in some locations, and even display their photorealistic 3D imagery. As such, you need to have an internet connection to run the software. Thus, every time you open Google Earth, the software will connect to the servers and exchange data. Google’s servers are used to host the imagery. The accuracy of these details can vary from place to place as the images weren’t taken on the same date and at the same time. Of course, this imagery will now have more details. If you zoom in enough, the images will change, showing you the closer version of the area that you have zoomed in on. It displays the Earth’s entire surface by using one single composited image which was taken from a far distance. This program’s imagery is shown on the digital 3D representation of Earth. ![]() Let’s see what other options you can expect from this program. Of course, those aren’t the only features found in Google Earth. You can use Google Earth to move all around the globe, but you can also zoom in and inspect whatever street you want using Street View. ![]() prj file describing the projection or the European Petroleum Survey Group (EPSG) code for the projection.In other words, Google Earth does mapping so that users can inspect Earth as if it was in front of them. Each image must be accompanied by one of: a text description of the map projection (WKT), an ESRI. Images should be north-aligned and have rotation parameters set to zero. Google Earth accepts imagery projected using a standard cartographic projection such as Universal Transverse Mercator (UTM), a satellite-based datum such as GRS80, or WGS84 or in Geographic Coordinates (aka “latitude/longitude”) with WGS84 datum. For data or maps that use the true WGS84 datum good alignment can be achieved by projecting to the “WGS 1984 Web Mercator” coordinate system, which uses the ”WGS 1984 Major Auxiliary Sphere” datum (GCS). The “true” WGS84 datum is ellipsoidal (GRS80 ellipsoid) and geocentric only the geocentric aspect is common to both. To answer the question specifically, Google Earth uses a Mercator projection based on a spherical datum (in ESRI parlance, datum = “Geographic Coordinate System GCS”) that is a modification of the WGS84 datum. ![]() One of the more technical questions that has plagued the Google Earth community is – Exactly what Datum does Google Earth use across its platform.įor those of you who may not know this, but in this context, the term datum refers to the coordinate system that serves as a reference for the software to carry out its simulations and various operations. ![]()
