In the time given for this assignment (about 20% * 28h * 5ECTS = 28h per person), we do not expect you to provide a perfect solution document what you’ve done and report how it could implement (see section below). We are interested in the solutions you come up with, those solutions are based on what you have learned so far in GEO1000, GEO1002, GEO1015, and this course. There are therefore many different workflows/methodologies to produce the CityJSON files. Notice that this assignment is more exploratory, and less prescribed, than the 2 previous ones. You have to download yourself the AHN3 point cloud (sorry it’s just too large!). While the two required datasets are publicly available via PDOK, we have prepared and extracted the footprints for the area that is relevant for this assignment.
#BUILD A VIRTUAL CITY ONLINE HOMEWORK HOW TO#
It is up to you to choose how to best segment and reconstruct them (we give some tips below). reconstruct, in 3D, the trees in the given area.This will be a TIN formed of the AHN3 points (simplified!) and constrained to the buildings footprints notice that the terrain is not shown in the image above The height will be obtained from a point cloud (AHN3) take polygons from a topographic map (BAG), and extrude them to create LoD1.2 buildings.The model must be delivered in the CityJSON format. The assignment is worth 20% of your final mark.įor this assignment you need to construct a 3D city model of the area of the TU Delft campus by combining two publicly available datasets in the Netherlands. Late submission? 10% will be removed for each day that you are late. Assignment 3 Creating a 3D city model from public datasets
