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.

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.

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.

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.

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.

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

RTree is a Python package with bindings for libspatialindex.

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

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.

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.

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.

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.

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

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

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.

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

The purpose of this library is to provide:

• An extensible framework that will support robust spatial indexing methods.

• Support for sophisticated spatial queries. Range, point location, nearest neighbor and k-nearest neighbor as well as parametric queries (defined by spatial constraints) should be easy to deploy and run.

• Easy to use interfaces for inserting, deleting and updating information.

• Wide variety of customization capabilities. Basic index and storage characteristics like the page size, node capacity, minimum fan-out, splitting algorithm, etc. should be easy to customize.

• Index persistence. Internal memory and external memory structures should be supported. Clustered and non-clustered indices should be easy to be persisted.

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

This package provides units of measure as required by the Climate and Forecast (CF) metadata conventions. Provision of a wrapper class to support Unidata/UCAR UDUNITS-2 library, and the cftime calendar functionality.

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.

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.

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.

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