geos-cli
A Command line interface for GEOS - Geometry Engine Open Source.
Each command does one thing well (buffer, centroid, envelope) by reading in a geometry, processing the geometry, and writing the geometry out as WKT. Individual commands can be connected with unix pipes.
geos-cli buffer -g "POINT (1 1)" -d 10 | geos-cli centroidgeos-cli is written in C++ using CLI11 and GEOS. The Google Test library is used to write unit tests. The project is built with CMake and dependencies are managed with conan.
