vectorvector – CLI for Contour Lines and Hillshade Generation
I’ve built vectorvector, an open-source CLI tool for working with elevation data. Key features: * Generates contour lines (vector), hillshade tiles (raster), and terrarium tiles (raster elevation) * Processes the entire planet in ~7 hours on consumer hardware * Algorithms: Marching Squares for contours, Horn for hillshade, and Ramer–Douglas–Peucker for line simplification Benchmarked on a MacBook Pro (M2, 64 GB RAM). Output is customizable and aimed at developers and GIS enthusiasts. Would love to hear your thoughts and feedback! Repo:…
