Fiona is GDAL’s neat and nimble vector API for Python programmers. Fiona is designed to be simple and dependable. It focuses on reading and writing data in standard Python IO style and relies upon familiar Python types and protocols such as files, dictionaries, mappings, and iterators instead of classes specific to OGR. Fiona can read and write real-world data using multi-layered GIS formats and zipped virtual file systems and integrates readily with other Python GIS packages such as pyproj, Rtree, and Shapely.

OpenGeoSys (OGS) is a scientific open source project for the development of numerical methods for the simulation of thermo-hydro-mechanical-chemical (THMC) processes in porous and fractured media. OGS is implemented in C++, it is object-oriented with an focus on the numerical solution of coupled multi-field problems (multi-physics). Parallel versions of OGS are available relying on both MPI and OpenMP concepts. Application areas of OGS are currently CO2 sequestration, geothermal energy, water resources management, hydrology and waste deposition.

CloudCompare is a 3D point cloud (and triangular mesh) processing software. It was originally designed to perform comparison between two 3D point clouds (such as the ones obtained with a laser scanner) or between a point cloud and a triangular mesh. It relies on an octree structure that is highly optimized for this particular use-case. It is also meant to deal with huge point clouds.

Imposm is an importer for OpenStreetMap data. It reads PBF files and imports the data into PostgreSQL/PostGIS databases. It is designed to create databases that are optimized for rendering/tile/map-services.

GMT is a collection of about 100 command-line tools for manipulating geographic and Cartesian data sets (including filtering, trend fitting, gridding, projecting, etc.) and producing high-quality illustrations ranging from simple x-y plots via contour maps to artificially illuminated surfaces, 3D perspective views and animations. The GMT supplements add another 50 more specialized and discipline-specific tools. GMT supports over 30 map projections and transformations and requires support data such as GSHHG coastlines, rivers, and political boundaries and optionally DCW country polygons.

Verde is a Python library for processing spatial data (topography, point clouds, bathymetry, geophysics surveys, etc) and interpolating them on a 2D surface (i.e., gridding) with a hint of machine learning.

This is a python implementation of the geodesic routines in GeographicLib.

This package provides a Python interface to PROJ, a cartographic projections and coordinate transformations library.

QGIS is an easy to use Geographical Information System (GIS). It is a GIS data viewer and editor. QGIS supports a number of raster and vector data formats, with new support easily added using the plugin architecture.

OSMnx is a Python library that lets you download geospatial data from OpenStreetMap and model, project, visualize, and analyze real-world street networks and any other geospatial geometries. You can download and model walkable, drivable, or bikeable urban networks with a single line of Python code then easily analyze and visualize them. You can just as easily download and work with other infrastructure types, amenities/points of interest, building footprints, elevation data, street bearings/orientations, and speed/travel time.

The RT Topology Library exposes an API to create and manage standard (ISO 13249 aka SQL/MM) topologies using user-provided data stores.

PHREEQC implements several types of aqueous models including two ion-association aqueous models. This package contains modifications for OpenGeoSys

GNOME Maps is a graphical map viewer. It uses map data from the OpenStreetMap project. It can provide directions for walking, bicycling, and driving.

H3 is a geospatial indexing system using a hexagonal grid that can be (approximately) subdivided into finer and finer hexagonal grids, combining the benefits of a hexagonal grid with S2's hierarchical subdivisions.

VirtualPG is a dynamic extension for the SQLite DBMS. It implements the VirtualPostgres driver, allowing to directly exchange data between SQLite and PostgreSQL; if SpatiaLite is available even PostGIS geometries can be exchanged form one Spatial DBMS and the other.

SAGA (System for Automated Geoscientific Analyses) is a Geographic Information System (GIS) software. It has been designed for an easy and effective implementation of spatial algorithms and it offers a comprehensive, growing set of geoscientific methods.

Iris is a Python library for analysing and visualising Earth science data. It excels when working with multi-dimensional Earth Science data, where tabular representations become unwieldy and inefficient. Iris implements a data model based on the CF conventions.

SpatiaLite is a library intended to extend the SQLite core to support fully fledged Spatial SQL capabilities.

ReadOSM is a library to extract valid data from within an OpenStreetMap input file (in .osm or .osm.pbf format).

The libmaxminddb library provides a C library for reading MaxMind DB files, including the GeoIP2 databases from MaxMind. The MaxMind DB format is a custom, but open, binary format designed to facilitate fast lookups of IP addresses while allowing flexibility in the type of data associated with an address.

This package provides a Python bindings for H3, a hierarchical hexagonal geospatial indexing system

GDAL is a translator library for raster and vector geospatial data formats. As a library, it presents a single raster abstract data model and single vector abstract data model to the calling application for all supported formats. It also comes with a variety of useful command line utilities for data translation and processing.

GNU libtextstyle is a C library that provides an easy way to add styling to programs that produce output to a console or terminal emulator window. It allows applications to emit text annotated with styling information, such as color, font attributes (weight, posture), or underlining.
