PDAL is a C++ library for translating and manipulating point cloud data. It is very much like the GDAL library which handles raster and vector data.

This is a very simplistic parser for string values according to the OSM opening hours specification.

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

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.

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.

geopy is a Python client for several popular geocoding web services. geopy makes it easy for Python developers to locate the coordinates of addresses, cities, countries, and landmarks across the globe using third-party geocoders and other data sources.

Proj is a generic coordinate transformation software that transforms geospatial coordinates from one CRS to another. This includes cartographic projections as well as geodetic transformations. Proj includes command line applications for easy conversion of coordinates from text files or directly from user input. In addition, Proj also exposes an application programming interface that lets developers use the functionality of Proj in their own software.

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.

TetGen is a program to generate tetrahedral meshes of any 3D polyhedral domains. TetGen generates exact constrained Delaunay tetrahedralizations, boundary conforming Delaunay meshes, and Voronoi partitions.

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.

GPlates is a plate tectonics program. Manipulate reconstructions of geological and paleogeographic features through geological time. Interactively visualize vector, raster and volume data.

LASzip is a library for compressing LAS files and uncompressing LAZ files. The LAS format is a file format designed for the interchange and archiving of lidar point cloud data.

PostGIS is a spatial database extender for PostgreSQL object-relational database. It adds support for geographic objects allowing location queries to be run in SQL. This package provides a PostgreSQL extension.

The Shapefile C Library provides the ability to write simple C programs for reading, writing and updating (to a limited extent) ESRI Shapefiles, and the associated attribute file (.dbf).

This package provides python-overpass, a Python wrapper for the OpenStreetMap Overpass API.

MaxMind DB is a binary file format that stores data indexed by IP address subnets (IPv4 or IPv6). This is a Python module for reading MaxMind DB files.

OWSLib is a Python package for client programming with Open Geospatial Consortium (OGC) web service (hence OWS) interface standards, and their related content models.

This package provides a GTK+ widget (and Python bindings) that when given GPS coordinates,draws a GPS track, and points of interest on a moving map display. Downloads map data from a number of websites, including https://www.openstreetmap.org.

Facilitates mapping by making natural earth map data from http:// www.naturalearthdata.com/ more easily available to R users. Focuses on vector data.

spatialite-tools is a collection of Command Line Interface (CLI) tools supporting SpatiaLite.

The libE57Format package provides a C++ library for reading and writing files in the ASTM-standard E57 format. E57 files store 3D point cloud data (produced by 3D imaging systems such as laser scanners), attributes associated with 3D point data (color and intensity), and 2D images (photos taken using a 3D imaging system).

GEOS provides a spatial object model and fundamental geometric functions. It is a C++ port of the Java Topology Suite (JTS). As such, it aims to contain the complete functionality of JTS in C++. This includes all the OpenGIS Simple Features for SQL spatial predicate functions and spatial operators, as well as specific JTS enhanced topology functions.

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

libgeotiff is a library on top of libtiff for reading and writing GeoTIFF information tags.
