A curate list of GIS tools and resources for river and watershed delineation using Python.

Libraries:

• PDAL: A C++ BSD library for python for translating and manipulating point cloud data
• PyLidar: A set of Python modules which makes it easy to write lidar processing code in Python
• libLAS: A C/C++ library for python for reading and writing the very common LAS LiDAR format
• laspy: A pythonic interface for reading/modifying/creating .LAS LIDAR files
• GDAL: A translator library for raster and vector geospatial data formats
• GeoPandas: Extends the datatypes used by pandas to allow spatial operations on geometric types
• Rtree: Spatial indexing for Python
• Shapely: Manipulation and analysis of geometric objects
• Descartes: Use Shapely or GeoJSON-like geometric objects as matplotlib paths and patches
• Fiona: OGR’s neat, nimble, no-nonsense API for Python programmers

Packages:

• WikiWatershed: Analyze mapped watershed data, visualize monitoring data, and run model simulations of human impacts on water quality
• KeckCaves: A set of application and libraries for geo data visualization
• Whitebox GAT: An open-source desktop GIS and remote sensing software package for general applications of geospatial analysis and data visualization
• WhiteboxTools: Performs common GIS analysis operations, such as cost-distance analysis, distance buffering, and raster reclassification
• WetChannelExtraction: Extract wet segments using high resolution DEMs and Intensity Rasters.
• DrainageNetworkExtraction: Extract channel and valley networks from high resolution DEMs
• TauDEM: A suite of Digital Elevation Model (DEM) tools for the extraction and analysis of hydrologic information from topography as represented by a DEM
• GeoAlchemy: Provides extensions to SQLAlchemy for working with spatial databases.
• PROJ.4 - Cartographic Projections Library: A generic coordinate transformation software, that transforms geospatial coordinates from one coordinate reference system (CRS) to another
• PyProj: Python interface to PROJ4 library for cartographic transformations
• pysheds: Simple and fast watershed delineation in python
• NetworkX: a Python package for the creation, manipulation, and study of the structure, dynamics, and functions of complex networks

Books:

• Geoprocessing with Python: teaches how to use the Python programming language, along with free and open source tools, to read, write, and process geospatial data
• Source code: Code for the book Open source geoprocessing with Python
