OpenOrienteering Mapper is a software for creating maps for the orienteering sport.

Osm2pgsql is a tool for loading OpenStreetMap data into a PostgreSQL / PostGIS database suitable for applications like rendering into a map, geocoding with Nominatim, or general analysis.

Mepo is a fast, simple, and hackable OSM map viewer for desktop and mobile Linux devices. It supports Wayland and X Windows.

Mepo works both offline and online, features a minimalist both touch/mouse and keyboard compatible interface, and offers a simple and powerful JSON API to allow the user to change and add functionality such as adding their own search and routing scripts, adding arbitrary buttons/keybindings to the UI, and more.

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.

ecCodes is a package developed by ECMWF which provides an application programming interface and a set of tools for decoding and encoding messages in the WMO FM-92 GRIB, WMO FM-94 BUFR and WMO GTS abbreviated header formats.

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.

librasterlite2 is a library that stores and retrieves huge raster coverages using a SpatiaLite DBMS.

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

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).

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

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

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.

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.

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

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.

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.

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

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

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

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.

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.

JOSM is an extensible editor for OpenStreetMap (OSM). It supports loading GPX tracks, background imagery and OSM data from local sources as well as from online sources and allows editing the OSM data (nodes, ways, and relations) and their metadata tags.

XyGrib is a Grib file reader and visualizes meteorological data providing an off-line capability to analyse weather forecasts or hindcasts. It is intended to be used as a capable weather work station for anyone with a serious interest in examining weather. This would include members of the sailing community, private and sport aviators, farmers, weather buffs and many more. XyGrib is the continuation of the zyGrib software package with a new team of volunteers.

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.
