The workflow is going backwards and Cad simply doesn't have enough info to do it in reverse. Projected UTMs of easting and northing in step 4 which you created from your mouse click.Geographic lat/long's you entered in step 1.Instinct tells us it should match, but it doesn't. Cad has indeed forced that 'clicked spot' to correspond to the lat/long of your pin, but it won't necessarily force your clicked spot to correspond to UTM meters shown in the Google image (it forced the x-meters and y-meters to your clicked spot, not the true easting/northing). Review your workflow and you'll see that in step 4 you instructed Cad to put the pin (the Bing Imagery) at the location of your mouse click. The reason they don't match is because the easting and northing coordinates shown in your Google image is referenced to UTM (Universal Transverse Mercator) zone 19 and the coordinates shown in the Cad image, the numbers at the bottom, are referenced to an arbitrary spot that you clicked with your mouse. If you want to match Google Earth's projection, then I'd recommend the WGS ellipsoid referenced to UTM84 zone 19north (meters). I would recommend a projection using Massachusetts State Plane, specifically Massachusetts Mainland (US-feet), EPSG 2249. What I'm doing wrong? Here are some images: The problem comes when I compare the coordinates in Autocad A visualĬheck of the location of the Marker on the map in Autocad and Google Earth shows that Then Autocad places a Marker on the drawing and the map that appears below. When Iĭo that the map show the same point as in Google Earth.ģ- I click "Next" and select a Coordinate System (WORLD-MERCATOR / WGS84 / Meter).Ĥ- I select a point in the drawing that correspond to the reference point in Google EarthĪnd use ortho to indicate the north direction. I want that it matches with Google Earth coordinate system.ġ- Get the lat/lon of a reference point (42.539081 / -70.941904) in Google Earth.Ģ- In Autocad click Insert>Set Location and drop a pin at the above point. I am trying to use georeference a drawing using the Set Location feature and Google Maps can be viewable by every internet browser without installation of any application, whereas Google Earth must installed on desktop.I have Autocad 2016.Google Maps is fully gratis, whereas Google Earth is only partially so.Google Maps doesn’t include extraterrestrial maps (Moon, Mars, and Sky), although Google Earth does.Google Maps uses Mercator’s projection in their applications, whereas Google Earth is presented in the form of virtual 3D globe in their software.Google Maps is available on both mobile and desktop devices, however Google Earth is exclusively available on PCs.Main Differences Between Google Maps and Google Earth Some governments have asked for only certain regions of Google’s satellite photos to be covered, usual locations with military installations. Some have deemed Google Earth to be a breach of privacy and national security, resulting in the program’s ban in some other countries. While increasing access to the software was viewed positively so it went off again. Google Earth Pro is an advanced version of Google Earth, Earlier Google stated that It went available for free for some time. Google Earth also allows users to view past models of the Earth’s maps. It additionally provides maps of the moon, Mars, and the sky available. As a result, Google Earth can only be used on a few operating systems, including Windows, Mac, and Linux.Įven though it is an executable file, the operation requires a proper and good internet connection. Google Earth is a desktop application that must be properly installed on desktops according to the operating system. It includes many technologies like Satellite imagery, aerial photos, local maps, 360° active incredible views of geographical regions like roadways or Street View, actual traffic statistics, and route optimization for walking, driving, biking, flying, and taking public transportation. Google Maps is commercial software and web-based mapping system developed by Google Inc. 500MB of disk space to install on the computer. Minimum Requirements for work A Smartphone with a good Internet connection. Historical Imagery Current cloudless satellite imagery. Navigates on a broader scale with the 3-D virtual world. Comparison Table Parameters of Comparison Google Maps Google Earth Navigation Navigates place to place, Turn by turn, Voice-supporter, Real-time updates. Google Earth allows the user to take a digital trip around the globe, complete with loads of sights, data, and other interactive features.
