We want to search the capital one postcode at a time. But we can only do it by selecting data away from a certain point ie the center of the post code. As we record the data in different post codes we want to minimise the overlap. hence we need to know the diameter / width of each postcode.
The output should be in an excel list : Postcode / Diameter
Statistical parameters : We assume postcodes are roughly round. But we want to catch 95% of the data and minimise the overlap data to 10% so capture is more important than duplication.
By clicking on the postcode in the picture it shows the height and width. Please choose a number to capture 90% of the area with as little overlap as possible. Then record the result in the execl table.
