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.

Command line tool for working with OpenStreetMap data based on the Osmium library.

Pyogrio provides a GeoPandas-oriented API to OGR vector data sources, such as ESRI Shapefile, GeoPackage, and GeoJSON. Vector data sources have geometries, such as points, lines, or polygons, and associated records with potentially many columns worth of data. Pyogrio uses a vectorized approach for reading and writing GeoDataFrames to and from OGR vector data sources in order to give you faster interoperability. It uses pre-compiled bindings for GDAL/OGR so that the performance is primarily limited by the underlying I/O speed of data source drivers in GDAL/OGR rather than multiple steps of converting to and from Python data types within Python.

Libosmium is a fast and flexible C++ library for working with OpenStreetMap data.

Spatialite-gui provides a visual interface for viewing and maintaining a spatialite database. You can easily see the structure of the tables and data contents using point and click functions, many of which construct common SQL queries, or craft your own SQL queries.

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.

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.

Cartopy is a Python package designed to make drawing maps for data analysis and visualisation easy.

It features:

• object oriented projection definitions

• point, line, polygon and image transformations between projections

• integration to expose advanced mapping in Matplotlib with a simple and intuitive interface

• powerful vector data handling by integrating shapefile reading with Shapely capabilities

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.

MetPy is a collection of tools in Python for reading, visualizing and performing calculations with weather data.

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.

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

ogr2osm is a tool for converting ogr-readable files into OSM format. It supports reading from OGR files like shapefiles or PostgreSQL database and converts data into osm or osm.pbf formats. A translation file can be used to manipulate the data during conversion.

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.

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.

Python version of geopack and Tsyganenko models, compatible with geopack05 and geopack08.

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.

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.

Tegola is a free vector tile server written in Go. Tegola takes geospatial data and slices it into vector tiles that can be efficiently delivered to any client.

ObsPy is a project dedicated to provide a Python framework for processing seismological data. It provides parsers for common file formats, clients to access data centers and seismological signal processing routines which allow the manipulation of seismological time series.

The goal of the ObsPy project is to facilitate rapid application development for seismology.

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 Python Shapefile Library (PyShp) reads and writes ESRI Shapefiles.

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.

QMapShack can be used to plan your next outdoor trip or to visualize and archive all the GPS recordings of your past trips. It is the successor of the QLandkarte GT application.
