This Data Plotting and Fitting page was developed as a third year laboratory for the School of Physics, University of New South Wales. The program will plot data into several different graphs. Graphs include a line graph, linear regression fit, exponential fit, power fit, Gaussian fit and Cos squared fit. The program can also calculate fit for the data if required. Full description.

The Computational Geophysics and Geoinformatics homepage contains online data and software tools for paleomagnetism and plate tectonics. The page includes information on paleomagnetic data, gravity anomalies, satellite altimetry, GOTOPO 30 topography tools, plate tectonic reconstructions, Mediterranean reconstructions, current research, a plate tectonic modeling tutorial and links to additional information. ...

This tide and tide prediction resource directory links to online tide predictors, tide observations/sea level measurements, tide prediction software you install to generate tide predictions on demand, and general information on tides and tide prediction. Full description.

At this site you can view either a map of the Earth showing the day and night regions at this moment, or view the Earth from the Sun, the Moon, the night side of the Earth, above any location on the planet specified by latitude, longitude and altitude, from a satellite in Earth orbit, or above various cities around the globe. Images can be generated based on a full-colour image of the Earth by day ... Full description.

This site contains Stereographic Projection and Rose Diagram plotting packages (GEOrient); a structural and drillhole calculator (GeoCalculator); strain, and shear zone calculators; geological field database information; and Geographic Information Systems (Mapinfo) software for plotting structural symbols on maps (GeoMapSymbol; previously GeoSymbol]. There are also several animations for teaching ... Full description.

The United States Naval Observatory (USNO) data services page provides tools for calculating the times of sunrise, sunset, moonrise, moonset, and civil twilight, as well as rise and set times for major solar system objects and bright stars. There is a section of lunar data that includes dates of its primary phases, a tool for calculating the illuminated fraction, and a graphic that displays the apparent ... Full description.

This program calculates an estimated time of arrival for various destinations in the Universe (for example, the planet Saturn). Visitor input a value for the speed they are traveling away from Earth, and have the option of selecting the units of speed. Full description.

This program simulates the collision of an asteroid or a comet with any planet in Solar System. Users can pick one of the nine planets in the Solar System or the Earth's Moon, choose the composition and diameter (size) of the projectile, and choose the speed of the projectile. Approximate results are returned. Full description.

Information is presented on Blue Moons, including what they are, where the expression and name came from, and which months have the most Blue Moons. A calculator is provided to see when past and future Blue Moons have and will occur. In addition, moon phases are charted for the next and last month, year, and Metonic Cycles. General Moon information is included, along with links for further information. ... Full description.

Corpscon is a Microsoft Windows-based program, which allows users to convert coordinates between Geographic, State Plane and Universal Transverse Mercator (UTM) systems on the North American Datum of 1927 (NAD 27), the North American Datum of 1983 (NAD 83), and High Accuracy Reference Networks (HARNs). Corpscon uses the National Geodetic Survey (NGS) program Nadcon to convert between NAD 27, NAD 83 ... Full description.
