SPASTC: a Spatial Partitioning Algorithm for Scalable Travel-time Computation

We present a Spatial Partitioning Algorithm for Scalable Travel-time Computation (SPASTC) Calculating travel-time catchments over large spatial extents is computationally intensive, with previous work limiting their spatial extent to minimize computational burden or overcoming the computational burden with advanced cyberinfrastructure SPASTC is designed for domain decomposition of travel-time catchment calculations with a user-provided memory limit on computation SPASTC realizes this through spatial partitioning that preserves spatial ...
