Samples of Geometry Technologies Work
 
Mapping The Outdoors offers customized maps that combine aerial photography with topographic maps, to identify prime locations for hunting, fishing, hiking, biking, walking, camping and other outdoor activities. Geometry Technologies designed and built the online mapping application for the Mapping The Outdoors web site that allows users to design and order their own maps.

The Climate Reference Network (CRN) is a network of climate monitoring stations currently being developed by the US National Oceanic and Atmospheric Administration (NOAA). Its main goal is to provide extremely accurate observations of temperature and precipitation for the purpose of better understanding of long-term climate change. Geometry Technologies provides software development and support for CRN at the National Climatic Data Center NCDC in Asheville NC. This includes software for data ingest, database design, data storage and retrieval, monitoring, metadata management, web display, graphical display, and scientific research.

Multigraph is an interactive viewing tool for time series data. Geometry Technologies developed Multigraph to provide interactive web-based access to graphs of weather data for the Climate Reference Network, but it is appropriate for any scalar data that is sampled over time. Multigraph is a client-server application; the client displays a graph in a web page, and lets the user move forward or backwards in time, modify the scales used, and control other aspects of the graph interactively. The server delivers data to the client as needed. Multigraph is written in Java and is open source software available from the multigraph web site at SourceForge.

To see quick samples of Multigraph in action, visit the CRN Hourly Observations page, where you can click on one of the Multigraph Plot Icon icons to view a graph of live temperature and precipitation data from any of the CRN observing stations. You can also view a Multigraph presentation of current and past weather conditions at my house by visiting the Geometry Technologies weather page.


Geomview is an interactive 3D viewing program for Linux and other flavors of unix. Geomview was written at the Geometry Center at the University of Minnesota between 1992 and 1996, by me (Mark Phillips), Stuart Levy, Tamara Munzner, and a lot of other people. Although the Geometry Center closed in 1998 and Geomview is no longer actively developed, it is still used by many people around the world. It is open source software and is available from the Geomview web site. Geometry Technologies provides support and custom development for Geomview users.

ScienceU is an interactive online science and math museum. It was developed initially at the University of Minnesota Geometry Center in 1997 and 1998, and then further by Geometry Technologies Inc. Development of ScienceU stopped in 1999 due to lack of funding, but we have kept the site online because we like it so much and because it showcases some of our early web development work.

WebEQ is a suite of tools for integrating mathematical or scientific notation into HTML documents. WebEQ was developed by Geometry Technologies Inc. between 1997 and 1999, and was the first application to implement the MathML standard for describing mathematical notation. Robert Miner, one of the founders of Geometry Technologies Inc., co-chaired the W3C working group that designed MathML. In the year 2000 Geometry Technologies Inc. transferred WebEQ to Design Science, makers of Equation Editor and MathType for Microsoft Word. Design Science continues to develop and market WebEQ under the direction of Robert Miner.

COMAP (Consortium for Mathematics and its Applications) is a non-profit agency that develops and disseminates mathematics curriculum materials. Geometry Technologies developed an interactive online subscription and library system for COMAP, as well as several web-based applications to support collaboration and communicate between authors and teachers. We also developed online registration systems for two student math contests that COMAP puts on each year, MCM (Mathematical Contest in Modeling), and HiMCM (High School Mathematical Contest in Modeling).

The Geometry Center was a National Science Foundation Center for Science and Technology at the University of Minnesota that was funded from 1990 until 1998. The mission of the Geometry Center was to explore ways that computers and computer graphics could be used to help research, understand, communicate, and teach mathematics. The Geometry Center pioneered some of the most innovative scientific and mathematical visualizations of the time, and developed one of the first web sites in existence, with some of the first experimental interactive web (CGI) applications. Although the Geometry Center closed in 1998, its web site is still available online. Geometry Technologies Inc. was founded in 1998 with the mission of carrying forward some of the work begun at the Geometry Center.
