Historical Digital Topographic File of the main wet infrastructure under management at Rijkswaterstaat, consisting of point, line and plane information.
The status of the product runs from 1993 (transition from analogue to digital product) to 2000 (transition from DTB rivers to DTB-Nat). This is also the reason that the stock is not fully filled with all rivers.
The DTB-Rivieren is followed by the DTB-Nat. File names of the DTB2000 (DTB-Droog and DTB-Nat) start with a D, e.g. D45bn and those of DTB-Rivieren with an R.
