Raster processing benchmarks for Python and R packages
Raster processing benchmarks
This repository contains a collection of raster processing benchmarks for Python and R packages. The tests cover the most common operations such as loading data, extracting values by points, downsampling, calculating NDVI, writing multilayer, cropping by extent and calculating zonal statistics. The comparison is made from the user’s perspective (the simplest functions are used and the code is not optimized), so the results do not represent the best performance.
The detailed results are available at https://kadyb.github.io/raster-benchmark/report.html.
Reproduction
- Download raster data (851 MB) from Google Drive or Earth Explorer (original source, registration required) and then unzip to
data/. - Run all benchmarks using batch script (
run_benchmarks.sh) or single benchmarks files.
Batch script
cd raster-benchmark
./run_benchmarks.sh
Single benchmark
Rscript stars/crop.R
