I'm new to Maps and Earth. I need help answering some basic questions about mapping before I embark on a project I am thinking of developing.
1. What are the dimensions (length and width, in metric) of the world when it's laid out as a 2D map? 2. Using Google Maps, is there a way to lay a grid on top of the map that adjusts according to zoom level? (For example, place a 1000x1000 grid on top of the map; each cell size will be bigger with more zoom, smaller with less zoom.) 3. Is there a way to capture a user selected cell from the grid mentioned in #2 (e.g. in response to a click event)? Also, the area covered by the cell in the grid mentioned in #2 (in terms of latitude and longitude) on a 2D map matches the area covered on Google Earth, right? Does anyone have any links to any good tutorial on how a sphere is laid out into a 2D plane? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Maps API" group.
