Analysis refers to software intended to analyze data, whether it be mathematical, instrumental, quantitative, or qualitative. This category includes many research and statistical packages as well as graphing tools for showing data trends and correlations.
Modeling software focuses on the digital creation or the digital re-creation of a design. Modeling software allows for digital simulation to explore possibilities, theories, and simulate results. It also allows for easy viewing of the design from perspectives that would otherwise be difficult.
This category includes mapping tools, Geographical Information Systems (GIS) tools, plotting tools, landscape analysts, and geological structure tool. Also included is Software for statistical gathering, analysis, computation, and visualization. Often used in research, polling, or surveying.
Apache OpenOffice is an open-source office productivity software suite. The applications include:
Apache OpenOffice is available for download here. OpenOffice may require java for some applications.
Origin is a proprietary computer program for interactive scientific graphing and data analysis. It is produced by OriginLab Corporation, and runs on Microsoft Windows. It has inspired several platform-independent open-source clones like QtiPlot or SciDAVis.
Graphing support in Origin includes various 2D/3D plot types. Data analyses in Origin include statistics, signal processing, curve fitting and peak analysis. Origin’s curve fitting is performed by the nonlinear least squares fitter which is based on the Levenberg–Marquardt algorithm.
Origin is primarily a GUI (Graphical User Interface) software with a spreadsheet front end. Unlike popular spreadsheets like Excel, Origin’s worksheet is column oriented. Each column has associated attributes like name, units and other user definable labels. Instead of cell formula, Origin uses column formula for calculations.
ParticleFlow is a two dimensional modeling software. This software, along with TopoDrive, are meant to simulate two groundwater processes: topography-driven flow and transport of fluid particles. It helps the user to better understand and determine groundwater flow processes.
