Assuming you get $lat and $long as latitidue/longitude of your starting point.
One approach is to take your input lat/long pair, create a range, then query for all records that fall in that range.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
