DAGGER is a library to process digital topography. It is designed as a flexible backend engine for Topographic Analysis and Landscape Evolution Models, providing a range of method to calculate flow routing (Single/Multiple flow, receivers,donors,links,...), resolve local minima (fill, carve, reroute, ...) and a lot of related problems.
Originally coded as a header-only c++ (most of it can still be used as such), now acts as the c++ backend of scabbard, a python package for topographic analysis, landscape evolution modelling and hydrodynamics/morphodynamics modelling.
dagger development started parallel to fastescapelib see here at the GFZ (Potsdam) as a follow up to CHONK. scabbard and DAGGER are now moving to mutualise development efforts and gradually migrate to use fastscapelib and libtopotoolbox behind the scene.
You want to use graphflood, CHONK or trackscape/popscape? See scabbard for using them from python. If you are interested by just using the c++ header-only version, contact me (I'll eventualy add documentation and example, although a lot of the code is being offset to scabbard where I develop new tools with taichi (GPU), numba (JIT-CPU), libtopotoolbox and fastscapelib).
