Есть много статей на тему знакомства с Google Map Api и Yandex Map Api, но про остальные картографические сервисы не так много практического материала. В недавнем времени работал с Api:
- Google map
- Yandex map
- Yahoo map
- Bing map
- OpenStreet map
И хотел обобщить работу с вышеупомянутыми сервисами, а именно инициализация карты и установление маркеров по клику мышки. Материалы в статье представлены в виде Html кода, javascript и результата — скриншота, а так же исходники на vs 2010 MVC3.
С Google map ситуация проще всего: практического материала много, мой пример выглядит следующим образом:

Обратите внимание на координаты, в Google идет сначала долгота, потом широта, а в Yandex наоборот!
