'Erhebung' is the noun corresponding to the verb 'erheben', which means 'anheben' (to lift) or 'erhöhen' (to raise/increase). This basic idea of 'lifting' appears in all meanings: data are 'gehoben' (lifted/collected), taxes are 'gehoben' (levied/collected) from citizens, and an uprising is when the people 'sich erhebt' (rises up).
Der Staat erhebt auf dieses Produkt eine hohe Steuer.
The state levies a high tax on this product.
You can easily recognize the meaning of 'Erhebung' from the context. If it is about data and statistics, it means data collection or a survey. In connection with finances and the state, it is about taxes. In geography and landscape, it means a hill, and in historical texts it often means an uprising.
Die neueste statistische Erhebung zeigt einen Anstieg der Geburtenrate.
The latest statistical survey shows an increase in the birth rate.
In the context of data collection, 'Erhebung' is often combined with certain verbs and adjectives. Typical phrases are 'eine Erhebung durchführen' (to conduct a survey), 'eine statistische Erhebung' (a statistical survey), or 'die Erhebung von Daten' (the collection of data).
Das Institut führt eine landesweite Erhebung zum Konsumverhalten durch.
The institute is conducting a nationwide survey on consumer behavior.
When it is about taxes or fees, 'Erhebung' is often used with the preposition 'von' (of). Common combinations are 'die Erhebung von Steuern' (the levying/collection of taxes), 'die Erhebung von Gebühren' (the collection of fees), or 'die Erhebung von Zöllen' (the collection of customs duties).

In the meaning of 'Aufstand' (uprising), 'Erhebung' is mainly used in historical, political, or very formal contexts. It often describes organized resistance against an authority.

height / amount
'die Höhe' and 'die Erhebung' can both mean a higher place in the landscape. 'die Höhe' sounds more general and is often used when you are standing on an elevated point or going there. 'die Erhebung' describes more specifically a spot in the terrain that is higher than its surroundings. This word sounds somewhat more formal and fits well in descriptions of landscapes or maps. They can be confused because both have to do with a hill or rise. In everyday language, people often say 'Höhe'; in more factual language, 'Erhebung' is more common.
