| Title: | Parallelization of existing tools in GRASS GIS |
- Abstract
-
- This project aims to parallelize geospatial tools/algorithms to enhance our abilities to utilize and analyze large-scale geospatial and remote sensing data. Although many geographic information system (GIS) tools are widely used, they haven’t been parallelized yet. The serial computation, while functional for modest datasets, significantly restricts the processing time and scalability necessary for handling increasingly larger geospatial datasets. Leveraging the potential of modern computing hardware, we can parallelize tools to mitigate these limitations. Several tools could benefit from parallelization, such as r.texture, r.horizon, r.fill.stats, r/v.surf.idw, r.viewshed, v.to.rast, r.to.vect, r.grow.distance, etc. These tools can be speeded up by parallelization with OpenMP and MPI. Moreover, CUDA can be used for these tools to compute raster and image processing on GPU.
