Let’s go back to our previous example: We again want to create a small grid of “perfect circles” on the Earth spheroid, but this time, we’ll succeed:

 

 

The 4 steps (for the 4 actions here above) are:
 

1.We generate a simple grid of points inside the 3857 SRID (using createGISGrid)
 

2.We transform each point into a small disc of radius 30Km (using ExpandGIS)
 

3.We want to display our grid of “prefect circles” on an Earth Map: To do so, we first need to reproject into 4326 SRID.
 

4.We create the .html Google Map based on the geometries in the 4326 SRID.
