RandomForest is a cool algo but be careful of the default tree depth hyper-parameter; it want's to overfit your data
Tree depth is how "deep" the decision tree goes, e.g. how many decisions are made before coming to an answer. If you use RF, but don't know about max tree depth...

Executing queries on spatial data can be difficult due to the complex polygonal shape of geographical boundaries. That's why geospatial systems resort to a strategy called “Filter-Refine” to evaluate geospatial predicates efficiently. Details in🧵

@MoSarwat The Anime (top right) versions are the most fun for me. But top left is a pretty authentic and interesting version. I think it’s a fun and engaging use of deep learning 🤷

@machsci So true. Love that quote.

Finally learned some basic raster analysis, and took the USGS topographic elevation + National Land Cover datasets to create a least-cost-distance path from Harrisburg to Pittsburgh. (Corridors in background). Results are interesting for high speed rail implications!
