Open Source C++ GIS Software

SAGA - System for Automated Geoscientific Analyses - is a Geographic Information System (GIS) software with immense capabilities for geodata processing and analysis. SAGA is programmed in the object oriented C++ language and supports the implementation of new functions with a very effective Application Programming Interface (API). Functions are organised as modules in framework independent Module Libraries and can be accessed via SAGA’s Graphical User Interface (GUI) or various scripting environments (shell scripts, Python, R, ...). Please provide the following reference in your work if you are using SAGA: Conrad, O., Bechtel, B., Bock, M., Dietrich, H., Fischer, E., Gerlitz, L., Wehberg, J., Wichmann, V., and Boehner, J.

GeographicLib is a small C++ library for: geodesic and rhumb line calculations; conversions between geographic, UTM, UPS, MGRS, geocentric, and local cartesian coordinates; gravity (e.g., EGM2008) and geomagnetic field (e.g., WMM2020) calculations.

Create, edit, visualize, analyze and publish geospatial information on Windows, Mac, Linux, BSD and mobile devices. For your desktop, server, in your web browser and as developer libraries. QGIS is a user-friendly open-source Geographic Information System (GIS) licensed under the GNU General Public License. QGIS is an official project of the Open Source Geospatial Foundation (OSGeo). It runs on Linux, Unix, Mac OSX, Windows and Android and supports numerous vector, raster, and database formats and functionalities. QGIS provides a continously growing number of capabilities provided by core functions and plugins. You can visualize, manage, edit, analyze data, and compose printable maps. We also collect case studies of how people all over the world use QGIS for their GIS work. You can view combinations of vector and raster data (in 2D or 3D) in different formats and projections without conversion to an internal or common format.

This project hosts various plugins for the OpenCPN chart plotter, which are not bundled with the core package. OpenCPN is a free software (GPLv2) project to create a concise chart plotter and navigation software, for use underway or as a planning tool. OpenCPN is developed by a team of active sailors using real world conditions for program testing and refinement.

** This site is of historical interest only. The project is active on www.gpsbabel.org and github. Some of the county/state files remain active, but no version of GPSBabel should be downloaded from this site. ** GPSBabel reads, writes, and manipulates GPS waypoints in a variety of formats. Over 100 supported formats include GPX, GeoJSON and Garmin serial and USB protocols, Geocaching Pocket Queries and *.loc and more! For Windows, Linux, Mac.

Earth3D is a program to display the earth as a 3D globe (including heightfields) in real-time. One can zoom until cities become visible. It uses huge datasets that are loaded on demand over the internet. It is possible to embed dynamic data into the view

The Orfeo Toolbox is a C++ library for high resolution remote sensing image processing. It is developped by CNES in the frame of the ORFEO program. More information is available at www.orfeo-toolbox.org It is based on the medical image processing library ITK and offers particular functionalities for remote sensing image processing in general and for high spatial resolution images in particular. Targeted algorithms for high resolution optical images (SPOT, Quickbird, Worldview, Landsat, Ikonos), hyperspectral sensors (Hyperion) or SAR (TerraSarX, ERS, Palsar) are available. Orfeo ToolBox has three main access depending on the category of user: write processing chains in C++ using existing filters or creating new ones, use the OTB applications, which is a plugin-based framework allowing to extend high-level processing chains from various environment ( command-line, QT, QGis, Python....) or use Monteverdi, a software for everyday life image manipulation and analysis.
