ich bräuchte den (ganzen) NRW-Raum

Das ist dann aber keine Aufgabe sondern ein Projekt , welches allein schon wegen der Datenmenge ziemlich anspruchsvoll ist.

Hier muss man dann entweder sehr fleißig sein oder ein "paar" Zeilen programmieren ....

Zur erwartbare Qualität der Daten ein Beispielkartenausschnitt :

Gruß Steffen

ich bräuchte den (ganzen) NRW-Raum, und es geht tatsächlich ausschließlich um die Höhe von Gebäuden; ja, gewisse Zeit steht dafür schon zur Verfügung - hast Du die Datensätze mit PostGis verarbeitet, oder gibt es dazu andere (Open-Source)-Tools?

Viele Grüße

Auch ist mir unklar, was du konkret benötigst. Das einzig "verwertbare" ist (für mich auf einen ersten Blick) wohl die Gebäudehöhe!?

Tja und ansonsten:
Welchen räumlichen Bereich benötigst du?
Wie viel bist du bereit in (Weiterbildungs-) Zeit zu investieren?

Gruß Steffen

Prima, das wäre das, was ich auch echt benötige!

Kannst Du ggf. einen Hinweis geben, wie das geht bzw. es geklappt hat?

Viele Grüße
