ZIP radius search

[Max Beermann]

Hey there,

long time no read;)

There is a ZIP > e.g. D-76131.
I want to create a list with all 20km-surrounded Zips.

_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _

For example:
https://www.suche-postleitzahl.org/plz-umkreis/76131

_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _

Is there any chance to solve it via xServer?

Thanks in advance!
Max

Hello Max,

gathering this kind of data is a bit aside of geocoding and not the usual purpose of the engine.
Sounds more like a task you can solve if you have the raw geometries of the zip areas within your spatial database.

It is also important to specify the definition of "distance":

adjacent postcodes - what is the istance between 76131 and 76133? Zero? because they touch?
Or 1.5km because this is the airline between the reference points? Picture taken from https://www.suche-postleitzahl.org

If you have a raw table of postcodes+(x,y) you could determine the airline distance approach by yourself.

Does it make sense to exchange details about available data structures? Then I'd link you with the data experts (e.g. Andreas Mensing).

Best regards,
Bernd

Good morning Bernd,

thanks for your reply.
You are right, a zip-database with coordinates should work for me!

I will give it a try and gonna inform you

Thanks
