1. Hi, I know that the is a possibility to "build" 3d structures - or rather to visualize shapefiles in 3d - in QGIS. ie. a "reconstruction" of a redoubt I have created earlier enter image description here
  2. Alhtough I have not found a case study where a rectengular-like features where visualized.
  3. What I am looking for is to (re)"construct" a simple 3d visualization of ALS-derived dtm interpretation of a POW camp from IWW - most of the buildings where pit-houses. To put it simply a rectengular roof sticking out of ground. enter image description here
  4. I know that it would probably be better for me to use some CAD software, but I have none experience with them and I do have GIS skills. I do not have access to ArcGIS and if possible I prefere not to use it.
  • What should be the output format? would a website be a soulution? – LaughU Oct 18 '17 at 7:26
  • You have a raster DEM of the area and a shapefile with a height to extrude? If R is an option, it's relatively straightforward to build that scene with the rgl package. – mdsumner Oct 18 '17 at 7:33
  • so what You are suggesting is a model where DTM and the housing features are merged in one? – archeogis Oct 20 '17 at 6:55

If you want to use QGIS I suggest to use this workflow:

Data needed:

  • DEM of the area of interest
  • A colada Model which represents the buildings( models can be downloaded from this website or can be created with sketchup)
  • A Point layer which represents the place, where the buildings used to stand
  • Optional: Fields on the point layer which may hold rotation, height or scale values
  • Optional: a base map or Orthophoto to use as overlay

Software need:

  • QGIS Version 2.14 or higher
  • QGIS2threejs Plugin
  • Sketchup: This might be the case if you want to be very realistic in the building of THE POW camp. You can use Sketchup (I am aware its a CAD software and op said he prefer not to use) to create the models if you dont find any suitable models in the provided links.


  • Load the data into QGIS
  • Deactivate every layer which you don't want to see in the final map ( for example the DEM and the points)
  • You will have something similar to the first image enter image description here

  • in the QGis2threejs tool, you chose COLLADA model as object type for the point layer.(see image 2)

enter image description here - as Collada file, you either choose one which is exported via Sketchup or a file downloaded. - The values for scale and rotation I mostly use trial and error approach and use fixed values. - As DEM use the file with the heights and use it as the DEM layer - When clicking on run you will get a website which allows flying through the model as shown in image 3

enter image description here

I've tested the workflow with QGIS 2.18.12 SRTM Data and fast created Collada models
