We are loading PlanetScope and SkySat tiles into an application using Google Maps API V3. It automatically requests tiles via the Planet API based on zoom level and x and y values.
Since Planet scenes may not take up the entire bounding box of the map, we are sometimes calling the API for x and y values that may not produce a tile.
Is there a way of checking ahead of time whether a tile is available at the x and y location so as to reduce the calls to the Planet API if there is no tile there? We call the API on the server so as to hide the API key, then return the resulting PNG file to the browser.
Many thanks for your help,
