It seems that Microsoft (of all people) is creating this database of building shapes for the known universe. They recently completed Australia and made it available. It is in a zipped geojason file - a format that I have no idea about.
I have loaded it to QGIS and it is huge. It took over 30min to load and it takes about 10min to redraw every time and I am not running it on a Pentium 4 with 8bits of ram either. I would like to clip the data to the states of Australia which I have a vector files or maybe regions in order to get the dataset smaller so it can be more usable. Can you clip geojason files ? or would I have to covert them into something like shapefiles? Any ideas on a workflow to do this? BTW I am running an I7-8700 with 16mb RAM and a NVIDIA Quadro P2000.
