Interactive map, showing in a given area (i need to change the range time by time) some features (again i have to chose them time by time) as streets, school, police station, fire brigade, hospitals, rivers, bridges and hotels. But i have to choose them time by time or create list and choose them. For example, i choose in this area (with gps coordinates) for 30 km of range, all the interest point, and the softwere show to me.
