A web based Metadata Catalog Server for data description and discovery. Supports both generic and geospatial data discovery. It implements international standards (e.g. ISO19115/19139/19119, ISO19115-3, DCAT-AP, CSW 2.0, OGC API Records). It originates from the United Nations and is used by many governments as geoportal software. Active development and discussion takes place on GitHub and OSGeo Discourse. You can also connect directly with the companies supporting the development. Source code available on github https://github.com/geonetwork/

DragMath is a drag and drop equation editor in the form of a Java applet. Once an expression is created the user can convert it into a variety of different linear syntax for mathematics, including MathML, LaTeX, Maple, Maxima or any user defined style. PLEASE NOTE: active code development has moved to GitHub. https://github.com/maths/dragmath

Lima VVA is a lightweight Windows application for road design and earthwork calculation. It is suitable for small to medium projects, where ease-of-use, low cost and quick results are paramount. It lets the user design the road interactively, while the geometry and earthwork quantities are automatically calculated in the background. By manipulating the construction parameters, other earthworks can be calculated, such as ditches, embankments, land fills, building sites — in short, anything suitable for the cross-section method. The program produces high quality drawings, reports, and construction data for the design. These results can be exported to other systems such as office, CAD and GIS software, surveying equipment, and systems for automated machine control.

Punt is a Open Source multi-language desktop application that allows the user to view the terrain of any world in 3D. Using open standards Punt can make use of data from the Internet combined with local data in common GIS-compatible formats.
