We have a little side project running where we need to create maps of different countries containing postcodes and postcode area boundaries, which are put in a database. Those maps are supposed to be usable for several reports and visual display - through the database entries. It appears it needs to be done from scratch (meaning we won’t pay for the data).
I’m completely new to QGIS and georeferencing and searched through several tutorials, but some clues are missing.
So far I have a blank shapefile of a country, which is already georeferenced. Now what i need to do (from my understanding):
Get the post code data and import it (which is hard for countries like Romania, since there seems to be nothing like tables available for free), OR put only the post code areas into the map manually. -> But how can you do that somewhat accurately? Just using polygons?
Make it usable for a database, e.g. using SpatiaLite.
Are there any good resources about the steps of such a specific task?
edit: Sorry for causing some confusion. I adjusted the question a little.
