World Map in Dymaxion Projection (print-cut-fold-and-glue)
Posted by smaprs on 5 November 2016 in English. Last updated on 12 November 2016.Hi,
Here there are two OSM based print-cut-fold-and-glue artwork for kids (and not so young), to share and help to spread OSM and geography interest:
World Map in Dymaxion Projection
Composed by OSMuser:smaprs (with QGIS and image editor) and with a little help from Brazilian OSM Comunity and others. - Free for copy and share under CC-BY-SA 2.0
Country names: www.openstreetmap.org © OpenStreetMap contributors
Grid/Country borders at: www.naturalearthdata.com (blank version)
Base Map: OSM Landscape www.thunderforest.com (colour version)
Ocean Floor Relief: Global Map Projector Equirectangular www.giss.nasa.gov
Dymaxion python script at: www.emergentweirdness.blogspot.com.br
To fit in Dymaxion Projection the OSM Base Map had to be firstly converted to a Plate-Carreé projection in 2:1 aspect ratio PNG picture. This was done in QGIS.

All these pictures I did, they are free for copy and share under CC-BY-SA 2.0
Instructions:
-Print and cut at thicker outer lines.
-Firstly do all folds, pressing them for both sides to make paper more ductile, then you can start to glue contiguous tabs.
-Last triangle may be just fit, not glued.
-In larger scales you may do it in thicker paper.
-Also it can be done a small hole in poles, to pass a line to hang the globe. (Tip: with this small hole, you can also carefully pass a folded wire through inner side to press last tabs to glue if you want, then remove the wire…)
Hope you like it. Try to do it.

Cool!
Can you post the instructions how to fold and glue in englsih?

Thank you all. Hi Brogo, there are no written instructions (nor in portuguese), it’s all to get visually in the small images at the top of each sheet: all folds have to be done to the same side. Also the little tabs to glue, all for inner side, with a thin gel glue strip. I’ve added a pic of folds done at the bottom.

Very nice! I’ll remember to use these in our next mapping session for kids.

Really nice! Sadly…I’m not able to see the python script, you refer to (http://www.emergentweirdness.blogspot.com.br/)…is there any chance for me to get it?
