Open Source C Mapping Software

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.

Viking is a free/open source program to manage GPS data. You can import, plot and create tracks, routes and waypoints, show OSM, Bing Aerial and other maps, geotag images, create routes using OSRM, see real-time GPS position (not in Windows), make maps using Mapnik (not in Windows), control items, etc. It is written in mostly in C (with some C++) & the GTK+3 toolkit. Viking is currently dual managed - with a corresponding Github presence at: https://github.com/viking-gps/viking Where you may find it easier to view the code and raise issues there too.

To use precompiled wheels: 1) go to releases (Files) and download tarball needed; 2) install it with command: python3 -m pip install /path/to/wheel.whl Or simply use URL in pip: python3 -m pip install https://sourceforge.net/projects/gdal-wheels-for-linux/files/GDAL-3.1.4-cp37-cp37m-manylinux_2_5_x86_64.manylinux1_x86_64.whl/download URL may be found under "View details" button (i) To use GDAL in C/C++ project you need to link gdal lib AND all libs located at dir GDAL.libs (usually this folder resides inside python site-packages) To compile your own wheels see information given at forefather project: https://github.com/youngpm/gdalmanylinux Usually this is done via command `make wheels` GDAL wheels for Windows are provided by Christoph Gohlke at https://www.lfd.uci.edu/~gohlke/pythonlibs/#gdal Built with PROJ (proj.db is included), GEOS, EXPAT. See Dockerfile.wheels for additional components.

EPSILON is a powerful Open Source wavelet image compressor. The project is aimed on parallel and robust image processing.

A C library for parsing/normalizing street addresses around the world. Powered by statistical NLP and open geo data. libpostal is a C library for parsing/normalizing street addresses around the world using statistical NLP and open data. The goal of this project is to understand location-based strings in every language, everywhere. Addresses and the locations they represent are essential for any application dealing with maps (place search, transportation, on-demand/delivery services, check-ins, reviews). Yet even the simplest addresses are packed with local conventions, abbreviations and context, making them difficult to index/query effectively with traditional full-text search engines. This library helps convert the free-form addresses that humans use into clean normalized forms suitable for machine comparison and full-text indexing. Though libpostal is not itself a full geocoder, it can be used as a preprocessing step to make any geocoding application smarter, and simpler.

A bike information system for cyclists in Berlin and Brandenburg (Germany) with a map view and a routing engine. There's a graphical interface (based on Perl/Tk) as well as an Web interface. Source code may be found at Github: https://github.com/eserte/bbbike/

ZMapServer is a Zope Product that provides a clean interface to the MapServer (http://mapserver.gis.umn.edu) web mapping application.

A navigation system that displays street maps and tracks a vehicle using GPS. Specific locations can be selected by street address. Routes and tracks can be created, edited, and saved in GPX format. Runs on most POSIX systems, the iPAQ, and the Zaurus.

The SELENA and RISe software tools are two packages to assist in computing earthquake damage scenarios. The damage probability for any specific structure follows the computation principles of HAZUS.

Two dimensional (2D) fine mesh finite element (FE) grid editing system. Includes constrained Delaunay triangulation, and automated grid resolution changes based on local attributes. Win32 and Motif GUIs. Mature application, now going open source.

A C library for reading and writing BSB format image files. Typically used for nautical charts, BSB image files use the .KAP extension and store cartographic information in addition to a run-length encoded raster image. Includes bsb2tif & tif2bsb tools.

A Tcl Package to read and write Shapefiles
