The Remote Sensing and GIS software library (RSGISLib) is a collection of tools for processing remote sensing and GIS datasets. The tools are accessed using Python bindings or an XML interface.
On open source geometry processing library focusing on regions and moving regions.
Algorithms for constructing regions, identifying connected components, creating moving regions, and performing operations on moving regions are included.
The pixelscan library provides functions to scan pixels on a grid in a variety of spatial patterns. The library consists of scan generators and coordinate transformations. Scan generators are Python generators that return pixel coordinates in a particular spatial pattern. Coordinate transformations are iterators that apply spatial transformations to the coordinates created by the scan generators. Transformation can be chained to yield very generic transformations.
upoints is a collection of GPL v3 licensed modules for working with points on Earth, or other near spherical objects. It allows you to calculate the distance and bearings between points, mangle xearth/xplanet data files, work with online UK trigpoint databases, NOAA’s weather station database and other such location databases.
Previous versions of upoints were called earth_distance, but the name was changed as it no longer reflected the majority of uses the packages was targeted at.
PyGeoprocessing is a Python/Cython based library that provides a set of commonly used raster, vector, and hydrological operations for GIS processing. Similar functionality can be found in ArcGIS/QGIS raster algebra, ArcGIS zonal statistics, and ArcGIS/GRASS/TauDEM hydrological routing routines.
PyGeoprocessing was developed at the Natural Capital Project to create a programmable, open source, and free GIS processing library to support the ecosystem service software InVEST. PyGeoprocessing’s design prioritizes computation and memory efficient runtimes, easy installation and cross compatibility with other open source and proprietary software licenses, and a simplified set of orthogonal GIS processing routines that interact with GIS data via filename. Specifically the functionally provided by PyGeoprocessing includes
- programmable raster algebra routine (vectorize_datasets)
- routines for simplified raster creation and statistics
- integration with vector based geometry in many of the routines
- a simplified hydrological routing library
(Python Web Processing Service) is an implementation of the Web processing Service standard from Open Geospatial Consortium. It offers an environment for programming own processes (geofunctions or models) which can be accessed from the public. The main advantage of PyWPS is, that it has been written with native support for GRASS GIS. Access to GRASS modules via web interface should be as easy as possible.
GeoDjango intends to be a world-class geographic Web framework. Its goal is to make it as easy as possible to build GIS Web applications and harness the power of spatially enabled data.
PyTOPKAPI is a BSD licensed Python library implementing the TOPKAPI
Hydrological model (Liu and Todini, 2002). The model is a
physically-based and fully distributed hydrological model, which has
already been successfully applied in several countries around the
world (Liu and Todini, 2002; Bartholomes and Todini, 2005; Liu et al.,
2005; Martina et al., 2006; Vischel et al., 2008).
