If you are working on a project in Google Earth, you will want to have a number of tools to help allocate researchers to the right places. Adding a grid to Google Earth is a great way to divide up the research.
There is no easy way to add grids that are built-in to Google Earth Pro, however, you can download an easy piece of software that does it for you.
Ge-Path is one such software and it is available for free. It allows you to very easily mark out the rectangle you want and input the number of grid lines.
To get started, simply download the software and install it.
Then you want to add two pins — one in the top left corner of your area of interest (AI) and one in the bottom right.
Export these pins as a KML file and import them into Ge-Path.
At this stage, you want to decide how many gridlines you want. Check the box “Make Grid” and input the number of lines. You don’t need to input the distance between lines unless you want squares of a certain area.
Then you simply need to click run and it will generate the new KML which you can import into Google Earth and add letters and numbers.
