![]() ![]() Here is a link to a paper ('08) discussing GE imagery accuracy from '08. Either make the adjustments for the placement in Arc, or let it ride as is pointing to close enough.When I make a drawing that will be consumed by engineers (who can get salty if they don't see Cartesian axes), I will set a UTM center lat/long to be in the project area to present the coordinate system while maintaining close to cartesian coordinates. You need to have an appreciation for precision for when to pursue it, and when to let it be representational for the data. What datum was being used? Any and every projection has areas where distortion that comes into play, sometimes in area calculation, sometimes linear, etc. Try to position the viewer so that it corresponds in viewing altitude to the overlay. Their imagery has errors in registration that you just have to deal with. Position the 3D viewer in the location where you want to set the overlay image. Then, click OK to complete the creation.You haven't mentioned the details, but Web Mercator and UTM isn't precise as you think. Make any additional changes to the position of the image in the viewer.Click View to change the view settings.Note: To make positioning the overlay easier, adjust the transparency so that you can see the overlay image and the earth beneath it. To open the Properties, right-click on the placemark in the 3D viewer or in the Places panel, and choose Properties (on a PC) or Get Info (on a Mac). I can tell because in ArcMap the road is inside the polygon and in Google Earth its clearly outside see images below) Ive read that Google Earth uses WGS 1984 as its projection, so I projected the shapefile to WGS 1984, exported it to KML/KMZ and still the polygon does not fall in the right place (see purple polygon in image 2) - the road is. Here’s an example of what it looks like in GE Pro. If you want to save the KMZ file to My Places then right click on the KMZ file and Save toMy Places. In GE Pro it will add the MKZ to your temporary places. Google Earth is an amazing tool that lets ordinary humanssans wings or jetpackzoom around the world. Use the slider to set the default transparency for the image. After saving the KMZ file, double click on it to open it in Google Earth Pro.UTM zone 44N WGS 84 a projected coordinate with that datum, but its units are in meters and the projection is a universal transverse mercator projection, it is in zone 44 in the Northern hemisphere. ![]() Note: Image that is updated automatically on a server will need refresh properties set. GCSWGS84 a geographic coordinate system with that datum, its coordinates are in decimal degrees. Click Refresh to set the refresh properties for your overlay image.To upload a file from your computer or network, click Browse. The image appears in the 3D viewer, with anchor points to position it.Near "Link," enter the image file URL (not the webpage URL) you want to use.If it didnt automatically add the toolbar, in ArcMap go to Customize > Toolbars > and click on Street View. This should add the following toolbar to ArcMap. You start the process in SketchUp, where you optimize the model for viewing in Google Earth. To use this Google Street View Python Add-in, first download the add-in by clicking the link at the top of this page. To be able to import the Google Earth images to ArcMap youll need the Portable Basemap Server software. Previewing a SketchUp model in Google Earth is great way to see how your model looks in the context of its surroundings. Position the 3D viewer in the location where you want to set the overlay image. This video is about adding Google Earth images to ArcGIS software.
