CyberGIS Toolkit

"CyberGIS Toolkit is a suite of loosely coupled open-source geospatial software components that provide computationally scalable spatial analysis and modeling capabilities enabled by advanced cyberinfrastructure.

The components are:

1. TauDEM. TauDEM (Terrain Analysis Using Digital Elevation Models) is a suite of high-performance Digital Elevation Model (DEM) tools for watershed delineation and the extraction and analysis of hydrologic information from topography as represented by a Digital Elevation Model.
2. Parallel PySAL. The Parallel PySAL library provides a set of scalable PySAL functions. Currently, parallel PySAL components implemented using the multiprocessing python library. The Fisher-Jenks classification algorithm is integrated in the toolkit;
3. pRasterBlaster. pRasterBlaster is a high-performance map reprojection software contributed by the Center of Excellence for Geospatial Information Science (CEGIS) within the U.S. Geological Survey;
4. PGAP. PGAP is a scalable Parallel Genetical Algorithm (PGA) solver for the Generalized Assignment Problem (GAP). This code provides an efficient PGA implementation for combinatorial optimization problem-solving and scaled up to 262K processor cores on BlueWaters with marginal communication cost.
5. Parallel Agent-Based Modeling (PABM). PABM is an illustrative software for scalable spatially explicit agent-based modeling (ABM);
6. gKDE. A multi-GPU code for data-intensive kernel density estimation (KDE). Spatial computational domain is first estimated for KDE. Then the study area is decompose into sub-regions through an adaptive partitioning approach. Each sub-region is processed by a GPU node. These GPU nodes are communicated through massage passing interface (MPI).
7. mapalgebra. This package contains a parallel map algebra code using CUDA, MPI, and Parallel I/O. It is extracted from a parallel geospatial programming models training package.
8. SPTW. This is a parallel IO code for writing GeoTIFF file on a parallel file system.
