A new mapping-related API from WeatherBug has a response type we don't see too often: images. The new service provides radar, temperature and other weather-related data as an overlay for Bing or Google Maps.
WeatherBug needs different URLs for Bing and Google because the way that tiles are arranged are different. For each platform, WeatherBug makes available five layers: Radar, Satellite, Temperature, Humidity and Pressure. For paid partners, more than 500 layers are available.
