When you select a map in 'My Maps' there should be a 'View in Google Earth' link in upper right that you can click.
Google has removed the 'View in Google Earth' link from the Google Maps options, however, you can still transfer it to Google Earth. First click the link icon then copy the URL under the 'Paste link in email or IM' label. Next, append "&output=kml" to the URL (without the quotes) and open it in your web browser to launch Google Earth.
UPDATE:
Note that this trick has been removed as of August 2012 and Google Maps no longer supports the undocumented output=kmlparameter.
Google has documented how to share data from Google Maps to Google Earth - see related link below.
If you mean pinpoints, routes, paths, etc... the answer is, you can't. I think what you may have heard is that you can transfer Google Chrome bookmarks between two computers with a Google Account.
Answer #2
You can, however, import your saved places into Google Docs or Google Maps (my places) then access them remotely via a NetworkLink from a remote computer. Google Earth will no sync two computers, but if you only want to transfer (copy) your saved places to another computer you can copy the local myplaces.kml file from the first computer to the second.
You can export places in Google Earth by right-clicking on a given Placemark or any Folder in "My Places" then select "Save Place As". You can also choose between saving as KML or KMZ.
Note that KMZ is the zipped version of a KML file so recommend to export as KMZ so any referenced local images, overlays, icons, etc. are also exported.

Google Earth Pro imports a number of GIS file formats such as CSV and ESRI shape files. For the free version of Google Earth you first need to convert the GIS file to a KML, KMZ, or GPX file.
By definition, a geographic information system (GIS) is a computer application used to store, view, and analyze geographical information. Google Earth is such a system.
Google Earth Pro is the professional version of Google Earth with advanced features for business users.Google Earth Pro has following improvements over the free version:Pro performance is fasterPro has higher resolution printing 4800 pixels vs 1000 pixels.Pro able to import GIS data files (e.g. GeoTiff, CSV files, etc.)Pro has area measurement toolPro has additional layers (e.g. U.S. Parcel and Demographics data)...Google Earth Pro has an annual subscription of $399 which includes support.Both Google Earth and Google Earth Pro use the same imagery. In other words, you don't get higher resolution imagery by paying for the Pro version.
Google Earth is a virtual globe, map and geographic information program that was originally called EarthViewer 3D. It maps the Earth by the superimposition of images obtained from satellite imagery, aerial photography and GIS 3D globe. It is available under three different licenses: Google Earth, a free version with limited functionality; Google Earth Plus, which included additional features; and Google Earth Pro ($400 per year), which is intended for commercial use. You can download the free version from the link mentioned in the related links.
I guess it is free to use however, you cannot distribute it on your own. In free version you cannot integrate your GIS data but there are another versions like Google Earth pro and Google Earth enterprise.
There are alternatives to Google Earth such as NASA World Wind from a desktop application perspective.Google Earth is available as a free and paid Pro version (no source code is available). NASA World Wind is open source project and source code is available. World Winddiffers from Google Earth in that there is no one and 'official' World Wind application, instead there are many demos and programs with different functionalities created both by NASA and users from around the world.For high-end GIS users ESRI sells a suite of 2-D and 3-D Map-related products (ArcGis, ArcMap, etc.)From a web browser context there is Google Maps, which is integrated with Google Earth and shows some of the same map data. No download or installation is required.There is also Microsoft's Bing Maps, formerly known as Virtual Earth, with their impressive "bird's eye" aerial photos.Other mapping web sites with satellite imagery are also available. See related questions and related links for more details.
Google Maps and Google Earth are used in geographic information systems (GIS).

You can get those by going to your local GIS. try searching on google for your county's GIS. Or try to enter your county's abbreviation in front of GIS, like this ABCGIS. ABC is a example of your county's abbreviation. good luck
GPS (global positioning system) gathers geographic positioning data and converts to a file that can be used by a GIS (global information system) which can map it to show the location of the actual coordinates.
I guess it is free to use however, you cannot distribute it on your own. In free version you cannot integrate your GIS data but there are another versions like Google Earth pro and Google Earth enterprise.
