The Google Earth Software Development Kit is entirely encapsulated inside a Dynamic Link Library called ge_sdk.dll. To use the SDK functions, the file must be placed in a location that your software project can reference. Depending on the language used, the DLL functions may or may not need to be explicitly imported for use. For example, if developing with C#, DLL functions must be imported using the P/Invoke attribute, DLLImport. However, if using C++, functions may be called if the DLL resides in the project's known reference paths. The accompanying gesdk.lib file and ge_src.h file should also be included in all C and C++ projects.
It is recommended that the newest version of Google Earth be used to avoid any issues with the GE SDK.
