Is there a program for visual editing of GPS coordinates?

Question

Cartography

Greetings.
I have a json array of coordinates. I would like to load them into some program and edit the points: move, merge, delete, etc., and after editing export them to json.
What software do you recommend?

Answer 1

here you draw areas, export the map to KML, then open it with a text editor, and combine them into one array. You just manually remove the transitions between different arrays, making them one data array.
This is how I made a map for a restaurant, which displayed the delivery area where they delivered, and when people wrote their address, a pin appeared on the map, and if the pin was inside the area of ​​this polygon, the order button became active.
