[Belgium] whitepaper: Computing a shapefile by Belgian zip codes

[Alexandre Detiste]

Hi,

I've followed a one-week course & I felt inspired ("once you pop, you can't stop")
so I finally documented these proceedings as I felt
they might be interresting to other mappers.

As this list is Belgium-specific material,
this list felt like the best place to share it.

PS: I'm confident one could do the same with Open-Street Map data,
it's only a matter of how much does cost your developer's time versus
the one-shot 100€ cost of buying the base data at National Geography Institute.


Greets,

Alexandre Detiste

Abstract:

In most datawarehouses, the lowest detail level for geographical analysis is the zipcode*sub-city;
but as in practice the sub-city is generaly encoded in a poor way; only the zipcode is usable.

The National Geography Institute provide for 100€ shapefile data at the 'statistical sector' level
that can be processed to get data at zipcode level at http://www.ngi.be/FR/FR1-5-2.shtm
