DaveThis book looks rather interesting... sort of vaguely like the Invercargill fire brigade maps on the library web site except Wellington and covering more of the city than just the central business district. https://www.thepost.co.nz/culture/360880749/book-extract-mr-wards-map-victorian-wellington-street-street @WellingtonChineseHistory have you found out about this?

MaxThe Open Building Population Layer (Canada) provides population estimates at the building level for geospatial analysis under open-source licenses ๐ฐ๏ธ๐จ๐ฆ It was just updated to include the latest census data ๐ , satellite-derived building height estimates as well as footprints and points versions ๐ก Check it out! https://maximfortin.com/project/obpl-ca-2021/ #opendata #buildingfootprints #population #python #geospatial #gis #geopandas #AI #Microsoft #canada #opensource
Do you work with large #BuildingFootprints layers and would like to find out where building footprints are missing? ๐ฐ๏ธ๐บ๏ธ๐๏ธ
As I was working with the #OpenBuildingPopulation layer, I identified a simple way to identify gaps in building data.
An interactive web map provides summary results at national scale for the #Microsoft #Bing Canadian Building Footprints products ๐จ๐ฆ
