Around me button in Google Maps

[mall1m]

Hi everybody,

I'm trying to find a way to create an "Around Me" function in googlemap for QlikView

for example, during my navigation, I often focus on one location, but then I'd like to modify my selection to show all coordinates within 5 km (or miles)

if my location is x and y (x= 45.13567 and y= 5.6487324)

I should make a calculation that selection everything in the following range x-5km to x+5km and y-5km to y+5km

does anybody think of a better way to do that ?

do you have an example ?

Thanks for your answer
