How to Use 3Dfier V1021 Portable Free20 to Create 3D Models from 2D GIS Data

Do you want to create realistic and accurate 3D models from your 2D GIS data Do you want to do it quickly and easily without installing any software or paying any fees If yes, then you should try 3Dfier V1021 Portable Free20, the open-source tool for creating 3D models from 2D GIS data.

3Dfier V1021 Portable Free20 is a tool developed by the 3D Geoinformation group at the Delft University of Technology[^5^] [^6^]. It takes 2D GIS datasets (e.g. topographical datasets) and \"3dfies\" them (as in \"making them three-dimensional\") by lifting every polygon to 3D. The elevation is obtained from a point cloud (it supports LAS/LAZ format), and the semantics of every polygon is used to perform the lifting. For example, water polygons are extruded to horizontal polygons, buildings to LOD1 blocks, roads as smooth surfaces, etc. Every polygon is triangulated (constrained Delaunay triangulation) and the lifted polygons are \"stitched\" together so that one digital surface model (DSM) is constructed. The aim is to obtain one DSM that is error-free, i.e. no intersecting triangles, no holes (the surface is watertight), where buildings are integrated in the surface, etc. This surface can then be used as input in simulation software for instance.

3Dfier V1021 Portable Free20 can output the 3D models in various formats, such as OBJ, CityGML, CityJSON, CSV (for buildings only), PostGIS, and STL. The ID of each polygon is preserved, and there is a 1-to-1 mapping between the input and the output. You can also configure the lifting options in the YAML file provided, and define new classes if needed.

So how can you use 3Dfier V1021 Portable Free20 to create your own 3D models It's very simple. Just follow these steps:

Download 3Dfier V1021 Portable Free20 from here [^7^]. It's a zip file that contains the executable file and some example files.

Extract the zip file to a folder of your choice.

Prepare your input files: a 2D GIS dataset (in any format supported by OGR) and a point cloud (in LAS/LAZ format). Make sure they have the same coordinate system and projection.

Edit the YAML file provided in the example folder to match your input files and your desired output format and options. You can find more details on how to edit the YAML file in the documentation [^6^].

Open a command line (Windows) or a console (Mac OS X and Linux) and browse to the folder where you extracted the zip file.

Run 3dfier with this command: 3dfier myconfig.yml -o output.ext, where myconfig.yml is the name of your YAML file and output.ext is the name and extension of your output file.

Wait for 3dfier to finish processing your input files and generating your output file.

Enjoy your 3D model!

That's it! You have just created a 3D model from your 2D GIS data using 3Dfier V1021 Portable Free20. You can now use it for visualization, analysis, simulation, or any other purpose you want. You can also share it with others or publish it online.
