In a groundbreaking approach to spatial analysis, a statistician generated 4.2 million transects across New York City’s streets in just 60 seconds. This was achieved by leveraging the capabilities of Geopandas and Polars, two powerful data manipulation libraries. The process involved creating points every 10 feet along each street using Geopandas’ interpolate function, then converting these points into perpendicular transects with Polars. This method not only drastically reduced computation time from days to seconds but also ensured precision in storm damage analysis by splitting roadways into equal intervals. The data used was from NYC Open Data, specifically the December 24, 2024 release of NYC Street Centerlines. Each transect was linked back to its original road segment via a unique identifier, allowing for further spatial analysis. This innovative use of technology showcases how combining different tools can solve complex spatial problems efficiently.
