New article on my website - deep dive into the City Summit 🏙️🗻 project. A lot of images, Python code snippets and a full breakdown of all the steps. My experience with @streamlit.bsky.social is also included. Read here: kamilraczycki.com/blog/City-Su...

I have released a City Summit 🏙️🗻 project on Streamlit! It generates a visualization of stacked building shapes for the whole city - resulting in a mountain-like shape. city-summit.streamlit.app You can also run whole code locally if you want. More info in the "About" tab. #gischat #dataviz

Currently working on a big new feature for the OvertureMaestro #Python library - getting data in the wide format (id + geometry + boolean columns based on classes and subtypes). This format will be perfect for machine learning use-cases. #Geospatial #GISchat #OpenSource #Geo

I'm having fun with Overture Maps buildings dataset and I'm trying to create the "average building" visualisation in Python. I have rotated all buildings around the centroid to keep edges in the same orientation. First image shows bigger buildings and second smaller buildings. Scale in meters.

Every semester at TCU, we give presentations to students to highlight professional applications of Geography. The point is that Geography is not just memorizing rivers and capitals: it is at the heart of critical business decisions firms make every day. Here's what I showed yesterday:
