What is Google Earth?

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.

What is Microsoft Visual Studio?

Visual Studio 2017 is an integrated, complete solution with development tools, cloud services and extensions that enables you and your team to create great applications and games for desktops, the web, Windows Store, Android and iOS.

Visual Studio 2017 provides everything you need to help you deliver software in less time and even better quality.

Preparing to Add Google Earth to Your Microsoft Visual Studio Program.

We are downloading the extension Interop.GEPlugin.dll from my computer.

We click on Browse and choose Interop.GEPlugin.dll from our computer.

Running the program in 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.
