Hi there,

I am wondering if there is a way to obtain ZIP code fractions that are captured by a radius. I know that you can export all the ZIP codes touched by a radius. But I need the fraction of the ZIP that is actually inside the radius. Essentially, given a radius, I am looking for an output like:

Code:

ZIP                    Fraction in Radius
-------------          -------------
12345                          78%
23456                          92%
...

Thanks a lot.

Pete

Hi Pete,

For everything there is a way

Search point by point in the radius for a street. Then filter out duplicate streetnames. Then you have a location object for every street in your radius.

Et voila each object has his zip code and you have to do some simple calculation to get the percentage.

Hi Wilfried,

Thank you very much for your reply. Please excuse my unfamiliar with MapPoint programming API, but could you please advice which function to use to find all the points within a radius and/or zip code? Thank you very much.

Hi Pete,

For each point you wants to check you calculate latitude and longitude. To see if you have an object you can use ObjectsFromPoint();

I have an article that more or less describe what you do. Do a search on 'snap to road' on this site. It start on a position and then it make a vector checking each point with 5 meter interval, increase radius 5 meter until the radius of the circle is reached.
