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.
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...
Automated detection of the unknown early map projection
New scientific software supporting the automated detection of the early map projection and its parameters. Useful for studying and analysis of different kinds of maps with the lack of information about the map projection.
The analysis is based on the minimization of residuals between control points on the early and current reference maps.
Designed for cartographers as well as for enthusiasts.
Available free of charge.
The awareness of the map projection is primarily important...
openModeller is a complete C++ framework for species potential distribution modelling. The project also includes a graphical user interface, a web service interface and an API for Python.
This is software for display geographical maps, written on C++. It's small and simple library, which allow to use it on PDA (like Palm and Windows Mobile) and desktop.
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
Roadnav is an open source street navigation solution capable of running on a variety of operating systems. It can obtain your position from a GPS unit, plot a map of your area, and provide verbal directions to locations in the USA.
NrdbView is GIS (Geographic Information System) for displaying and editing of spatial data stored in .shp shapefiles( M, Z and Multipatch). NRDB View Use FreeImage lib to display georeferenced images. Actually MFC c++ but working on WxWidget migrating.
