Besides various sources of open geometry data provided by the different communities, here is a collection of word data collected on the larger scale level.

In 2017 and 2018 Microscoft released the data of 9.8 Mil. buildings (2017) and 125 Mil buildings (2018) from the US as Open Data (Blog-Post).

The 2018 release can be downloaded from GitHub in the GeoJSON format. As for now, Monde cannot directly read GeoJSON, you need to convert those to the Shapefile format, for example using this web service: GeoJSON to SHP File.

However, it seems that most of the building heights, which are essential when working with ENVI-met, are missing in the 2018 release. But in the smaller 2017 dataset, they are existing and read-to-use. While these data are not in GitHub, they can be accessed through the OpenStreetMap Wiki State-by-State (make sure to scroll down to March 2017 Release). Moreover, these data are already in the Shapefile format and can directly be imported into Mode.

Hint: First setup your Monde world with the georeference of your requested location and define the size of the map. Then import the shapefile and select the “Ignore objects outside of map” option. Otherwise you will get an extremely large dataset.
