What on-line Apps would give me the elevation of any location I want?
For example, I would like to plan an exit route for my family in case a flood should come in this area. Some of the roads go thigh ground, but there're some dips along the way. I need a way to find what places along a highway might dip below the flood plain. I t grid sing Google maps, but could not find a quick way to find elevation information.
Any ideas?
Maybe a Android App for my smartphone or iPhone?
