Samples of Geometry Technologies Work


	Multigraph Multigraph is software for creating two-dimensional scientific data graphs in web pages. It can read data in a variety of formats, and allows the user to customize the appearance of the graph. Multigraph provides interactive "pan" and "zoom" capabilities, giving the viewer the ability to change the horizontal and/or vertical scales in the graph on the fly. Multigraph also has the ability to read data from a web service, which allows it to be used to "surf" through large datasets, downloading only those the parts of the data that are needed for display. Multigraph is used extensively on NOAA's National Climatic Data Center web site, and on the NOAA Climate Services Portal. You can read more about Multigraph and see other examples at the Multigraph web site. You can also view a Multigraph presentation of current and past weather conditions at my house by visiting the Geometry Technologies weather page.
	Integrated Station Information System (ISIS) ISIS is a very flexible storage and management system for metadata related to weather and climate monitoring stations. It provides for entry, viewing, and storage of arbitrary metadata schemas, and tracks and displays the history of metadata values over time, as well as current values. It is used to track information for NOAA's CRN (Climate Reference Network), HCN-M (Historical Climate Network - Modernization), CHIP (COOP Historical Integration Project), and HPN (Hawaii Precipitation Network) stations.
	The Geometry Center 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.
	COMAP 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).
	Science U 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.
	Geomview 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.
	Climate Reference Network 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.
	Mapping The Outdoors 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.
