A toolbox for spatial analysis.

Building

Requirements

• cpp-infra (https://github.com/VITObelgium/cpp-infra)
• Eigen (https://eigen.tuxfamily.org/) Optional
• Vc (https://github.com/VcDevel/Vc) [simd support]
• Doctest (https://github.com/onqtam/doctest) [unit tests]

The library is built using CMake:

cmake -G Ninja "/path/to/geodynamix"

Build options

The following CMake options are available for toggling functionality:

• GDX_ENABLE_SIMD Build with simd support for DenseRaster (default = sse instructions) (requires Vc)
• GDX_AVX2 Build with avx2 simd instructions support
• GDX_ENABLE_OPENMP Build without openmp acceleration support
• GDX_ENABLE_TOOLS Build the geydynamix tools
• GDX_ENABLE_TESTS Build the c++ unit tests
• GDX_ENABLE_TEST_UTILS Build the unit test utilities (raster equality asserts, usefull for unit tests in depending projects)
• GDX_ENABLE_BENCHMARKS Build the micro benchmarks
• GDX_PYTHON_BINDINGS Build python bindings
• GDX_INSOURCE_DEPS Use submodules for internal dependencies
• GDX_INSTALL_DEVELOPMENT_FILES Install the geodynamix development files (headers/libs)

Using geodynamix in your project

directly add the source directory in your cmake project

# first set the enabled components in the cache
set(GDX_PYTHON_BINDINGS OFF CACHE BOOL "" FORCE)
set(GDX_ENABLE_TESTS OFF CACHE BOOL "" FORCE)
set(GDX_ENABLE_TEST_UTILS ON CACHE BOOL "" FORCE)
set(GDX_ENABLE_TOOLS OFF CACHE BOOL "" FORCE)
set(GDX_PYTHON_BINDINGS OFF CACHE BOOL "" FORCE)
set(GDX_ENABLE_SIMD ON CACHE BOOL "" FORCE)
set(GDX_AVX2 ON CACHE BOOL "" FORCE)
add_subdirectory(geodynamix)

or use the installed cmake module

find_package(Gdx CONFIG REQUIRED)
target_link_libraries(mytarget PRIVATE Gdx::gdxcore Gdx::gdxalgo)
