# I was looking up information on estimation theory and came across this interesting question on a forum. Take a stab at it: “I’m assigned a task involving solving a problem that can be described as follows: Suppose I’m driving a car around a lake. In the lake there is an island of irregular shape. I have a GPS with me in the car so I know how far I’ve driven and every turns I’ve made. Now suppose I also have a camera that takes picture of the island 30 times a second, so I know how long sidewise the island appears to me all the time. Also assume I know the straight line distance between me and the island all the time. Given these conditions, if I drive around the lake for one full circle, will I be able to estimate the perimeter of the island? If yes, how? Thanks.” [I don’t expect formulas or algorithms but rather approaches. While it’s estimation theory, the answers can be pragmatic “rule of thumb” heuristics. (what you would do in that situation)]
