Got excited and took it out for a spin, all looking great! Here's how you can read/write geospatial data between R and Python like it's the XXIst Century (also, in the same notebook thanks to the https://t.co/mf2OucmOI4). Notebook at: https://t.co/tffEeedBUn

The package has flexibility to calculate morphology metrics on grids, in polygon zones, and using focal windows. Check out the code/docs here: https://t.co/GTJI3rB1kk All the data and settlement classification from our paper are available! https://t.co/rwVeZSICqr

The paper also presents an example of generating a gridded classification of settlements for England, Scotland, and Wales using only patterns in buildings and unsupervised clustering

At what time on New Year's had most of the world's people started the year 2020? A little trivia, and a fun use for @WorldPopProject data. https://t.co/Tdyzg1RkuM Happy (belated) New Year to all!
