I am working on a project to get my home city into Minecraft (Harrisburg, PA - pop. 50,000). I have a QGIS file of about 40 layers consisting of:
- 2D shapefiles (polylines & polygons - to describe materials or edges)
- 2D shapefile of buildings (heights based on a BLDGHEIGHT value in the attribute table)
- 3D DEM (using this for the Ground Level of the Minecraft World)
I have seen what could be done in converting GIS to Minecraft from some of the how-to links. I have two concerns, what data cleanup should I be concerned with and would there be anyone out there who might be able to help guide me through the process this next month?
This project started in 2013 as an idea to take a 2D image and "loft" a Minecraft world from the pixels (World Painter). This worked well and created a flat creative world. Unfortunately the area was only one neighborhood in the city, approximately an 1/8 of the city. The image allowed some changes in elevation from the Susquehanna River with an approximate 30' change in elevation from the river - water, grass, roads, curbs, and building footprints. Unfortunately everything was flat and buildings were only represented by 2D footprints and not the true heights of buildings. View Screenshots of Harrisburg Midtown Minecraft
Two years ago I started the process using GIS data to cleanup buildings and curbs and add a DEM because I saw what could be done with FME. I had hoped that this would be a K-12 educational process to help students get into Geospatial Technologies as well as Architecture, Engineering and Construction. Now for 2021 I am working with a Young Professionals of Color group and we're looking to use this Minecraft World to link up with Harrisburg's Comprehensive Planning process for continued public engagement. I have shapefiles considing of Acad Blocks of Trees & Shrubs, Streetlights, Storm Drains and Maintenance Hole Covers. I am not sure that this data would convert correctly so that Minecraft objects could represent them - trees and possible glowstone for streetlights. I also have underground Storm Water Main and I am not sure if that could be added below the surface. This way students could work with future projects to discuss green infrastructure, flooding, mobility, updating Minecraft as projects happen this next decade.
I am including an image of what is in QGIS and I recognize that I am outside my limit of knowledge in trying to convert DEM and shape files to Minecraft. I know there is a lot of work to do yet, but I finally see the end. At the very least I know that I could default to 2D using World Painter getting things to the correct scale.
