In this article, Microsoft Visual Studio programme will learn how to add us the google earth add-on and assume control. This programme is the intended position provides us to find by courtesy of entered latitude and longitude information.The application be able to do need some libraries and plunging add-on.
Google Earth is a geobrowser that accesses satellite and aerial imagery, ocean bathymetry, and other geographic data over the internet to represent the Earth as a three-dimensional globe. Geobrowsers are alternatively known as virtual globes or Earth browsers.

We are downloading the extension Interop.GEPlugin.dll from my computer.
We click on Browse and choose Interop.GEPlugin.dll from our computer.
To run this application on our computer, we need to download GoogleEarthPluginSetup.exe and install it on our computer.

When the go to toggle button is pressed, it goes to the position where the latitude, longitude and altitude values in the textboxes are.
In the Google Earth program, we view the latitude and longitude information of Karabuk University Rectorate in degrees, minutes and seconds.
We checked the correctness of the translation from degree to decimal.
With this program, we can access latitude and longitude information on satellite images wherever we want.This program can be improved a lot and different programs can be developed.
