Earth System Modeling Framework
ESMF is software for building and coupling weather, climate, and related models. The premise is that complicated applications should be broken up into smaller pieces, or components. A component is a unit of software composition that has a coherent function, and a standard calling interface and behavior. Components can be assembled to create multiple applications, and different implementations of a component may be available.
Earth3D is a program that visualizes the earth in realtime in a 3D view. It uses data from NASA, USGS, the CIA and the city of Osnabrück. Features include: viewing the earth as a whole, zooming in until countries, cities and even single houses become visible, and embedding external data like current earthquake positions or cloud data.
GeoXPlanet is a program that integrates geolocation technology and xplanet. View the earth, with a geographic plot of the computers you've connected to, directly on your desktop background in near real-time.
Gpredict is a real-time satellite tracking and orbit prediction application. It can track an unlimited number of satellites and display their position and other data in lists, tables, maps, and polar plots (radar view). Gpredict can also predict the time of future passes for a satellite, and provide you with detailed information about each pass.
Just Moon is a moon viewer for Linux (and other unixlike platforms).
rmap is a package that will allow you to generate images of the earth from a distance or fairly zoomed in. The code is a small C bianary that reads a datafile of vectors to
generate the image. The actual image is generated from the libgd library, which will either generate a gif, png, or jpeg based on the version of libgd and auxilary libs you have.
saros enables you to find any solar eclipse in between about 2500 BC to 3500 AD.
Suri Pluma is a satellite image processing tool and visualizer. It can open the most common image formats without importing to an internal format and minimizing the memory required for visualization. It is designed to be modular and extensible. It has a meassurement tool (distance and areas with error estimation) and geographical and map coordinate information.
Xplanet was inspired by Xearth, which renders an image of the earth into the X root window. All of the major planets and most satellites can be drawn, similar to the Solar System Simulator. A number of different map projections are also supported, including azimuthal, Lambert, Mercator, Mollweide, orthographic, and rectangular.
XTide is a tide clock / tide predicting program.
