GRASS (Geographic Resources Analysis Support System), is a Geographic Information System (GIS) software suite used for geospatial data management and analysis, image processing, graphics and maps production, spatial modeling, and visualization.

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.

Routino is an application for finding a route between two points using the dataset of topographical information collected by https://www.OpenStreetMap.org.

This package provide Python bindings to the C library libmo_unpack which contains packing methods used to encode and decode the data payloads of Met Office UM Post-Processing and Fields files.

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

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

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).

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

CDO is a collection of command-line operators to manipulate and analyse climate and NWP model data. Supported data formats are GRIB 1/2, netCDF 3/4, SERVICE, EXTRA and IEG. There are more than 600 operators available.

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

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.

JMapViewer is a Java component which easily integrates an OSM map view into your Java application. It is maintained as an independent project by the JOSM team.

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.

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

Tippecanoe creates scale-independent view of data, so that the texture and density of features is visible at every zoom level, instead of dropping features at lower levels.

Mapnik is a toolkit for developing mapping applications. It is basically a collection of geographic objects like maps, layers, datasources, features, and geometries. At its core is a C++ shared library providing algorithms and patterns for spatial data access and visualization. The library does not rely on any specific windowing system and can be deployed to any server environment. It is intended to play fair in a multi-threaded environment and is aimed primarily, but not exclusively, at web-based development.

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.

Navit is a car navigation system with a routing engine.

It is meant to work with touchscreen devices, but it also works without a touchscreen. It also supports text to speech.

It can be configured extensively through its own configuration file format. For instance we can configure the graphical interface, and which map data is to be displayed at which zoom level.

It supports different routing profiles: bike, car, car_avoid_toll, car_pedantic, car_shortest, horse, pedestrian, truck.

It can use gpsd or NMEA GPS directly to get position data. It also works without GPS: in this case users can also enter position data directly.

It can also be used to log GPS data to files using the GPX or NMEA formats, or to replay NMEA data.

For maps, it can uses its own "binfile" map format, or Garmin map file format, and data from OpenStreetMap, Garmin maps, Marco Polo Grosser Reiseplaner, Routeplaner Europa 2007, Map + Route.

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.

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.

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.

This project contains a few tools which are used in the OpenStreetMap project. They can be used to convert, filter and update OpenStreetMap data files.

The miniSEED library provides a framework for manipulation of SEED data records, a format for commonly used for seismological time series and related data. The library includes the functionality to read and write data records, in addition to reconstructing time series from multiple records.

OpenCPN is a chart plotter and marine navigation software designed to be used at the helm station of your boat while underway. Chart a course and track your position right from your laptop.
