FOSS4G NA 2024 - Speeding Up Raster/Vector Zonal Analysis with exactextract - Dan Baston

Project Geospatial

Dan Baston presents “exactextract,” a library designed for efficient raster/vector zonal statistics analysis. This tool accurately transfers information from raster datasets to vector datasets, addressing limitations in existing methods. Highlights 🌍 Dan Baston is a software engineer focusing on open-source projects, primarily for federal government consulting. 🛠️ “exactextract” simplifies the process of zonal statistics, especially for large and complex datasets. 📊 The library efficiently handles raster data, making it suitable for diverse applications like climate modeling. ⚡ It improves speed and accuracy compared to traditional methods like point-in-polygon tests. 📈 Benchmarks indicate significant performance improvements over existing tools like QGIS and Python’s raster stats. 🧠 The library allows for population-weighted calculations, enhancing analysis relevance. 📦 Recently released a Python interface, expanding accessibility for users.
