libnova is a general purpose, double precision, astronomical calculation
library. The intended audience of libnova is C / C++ programmers, astronomers
and anyone else interested in calculating positions of astronomical objects.
Merkaartor is an openstreetmap mapping program. Merkaartor focuses on
providing a visually pleasing but performant editing environment for
free geographical data.
It is based on Qt5.
This program draws the Solar System's bodies in simulated 3-dimensionality.
You can view all the planets, their moons and a few spaceships in motion,
trace them, follow them, orbit them, and even control them.
OpenUniverse was formerly known as Solar System Simulator (Ssystem). It was
initially released in 1997 with the intent of creating a rotating display of
the Earth on a mainstream PC. Ssystem version 1.0 was only aware of the
planets. Version 1.2 added moons; and 1.6, more means of movement and
better textures.
The program has been renamed OpenUniverse 1.0 to underline the concept
behind its further development: openness for the whole Universe, not just
the solar system -- open for anyone to use, extend, and change.
Stellarium is a free open source planetarium for your computer. It shows a
realistic sky in 3D, just like what you see with the naked eye, binoculars,
or a telescope. It is being used in planetarium projectors. Just set your
coordinates and go.
This is current stable version based on Qt 5. For the previous, Qt 4 based
one, please install `astro/stellarium-qt4' port instead.
Planets is a simple interactive program for playing with simulations of
planetary systems.
PP3 creates celestial charts. It generates resolution independent maps of very
high graphical quality. They can be used for example as illustrations in books
or on web pages. You may use own databases or free ones from the Internet.
astLib is a set of Python modules that provides some tools for research
astronomers. It can be used for astronomical plots, some statistics,
common calculations, coordinate conversions, and manipulating FITS images
with World Coordinate System (WCS) information through PyWCSTools - a
simple wrapping of WCSTools by Doug Mink. PyWCSTools is distributed (and
developed) as part of astLib.
Astropy is a package intended to contain core functionality and some common
tools needed for performing astronomy and astrophysics research with Python. It
also provides an index for other astronomy packages and tools for managing
them.
QLandkarte GT is the ultimate outdoor aficionado's tool. It supports GPS maps in
GeoTiff format as well as Garmin's img vector map format. Additional it is the
PC side front end to QLandkarte M, a moving map application for mobile devices.
And it fills the gap Garmin leaves in refusing to support Linux. QLandkarte GT
is the proof that writing portable applications for Unix, Windows and OSX is
feasible with a minimum of overhead. No excuses!
QLandkarte GT does replace the original QLandkarte with a much more flexible
architecture. It's not limited to a map format or device. Thus if you think your
Magellan GPS or other should be supported, join the team.
Additionally it is a front end to the GDAL tools, to make georeferencing scanned
maps feasible for the normal user. Compared to similar tools like QGis, it's
target users are more on the consumer side than on the scientific one.
QLandkarte GT might not let you select every possible feature of the GDAL tools,
but it will simplify their use to the demands of most users.
This program generates, but does not display, image files containing
raster maps of the Earth. It includes public-domain, vector data from
which they are drawn, describing the continents, bodies of water,
boundaries of countries and U.S. states, and a few cities. Command-line
options allow centering the maps at a particular latitude and longitude
and zooming in.
