The Muninn Project aims to programmatically recreate scenes of historical events using Linked Open Data - and with the ever-increasing availability of high-quality 3D printers, we are motivated to 3D-print these scenes. In this particular post, we will talk about how to 3D-print a battlefield: the trenches of Vimy Ridge. We believe that 3D-printed models of battlefields, such as the trenches of Vimy Ridge, could be quite useful to archeologists & other individuals studying past historical events, namely the Battle of Vimy Ridge. We will discuss how to retrieve 90m-resolution elevation data inside a bounding box from the Shuttle Radar Topography Mission (SRTM), how to scale & project it with the Geospatial Data Abstraction Library (GDAL) and also how to convert it to an STL file that can be 3D-printed; we will also discuss how to retrieve lists of trench coordinates from the Muninn Project's SPARQL server, and how to extrude trenches on our model of Vimy Ridge before 3D-printing it. Lastly, we will discuss issues regarding the size & resolution of our model of Vimy Ridge and suggest how we might improve the quality of our model in the future. Thanks to Lawrence Willett for letting us use his 3D printer.
