Manifold System is a geographic information system (GIS) software package developed by Manifold Software Limited that runs on Microsoft Windows. Manifold System handles both vector and raster data, includes spatial SQL, a built-in Internet Map Server (IMS), and other general GIS features. History The development team for Manifold was created in 1993 to optimize mathematics libraries for a massively-parallel supercomputer created in a joint venture between Intel Corporation and the US Department of Defense. The team subsequently embarked on a plan to create and sell mathematics libraries, including the General Graph Facilities library (GGF) and the Computational Geometry Library (CGL), under the name of the Center for Digital Algorithms. A series of "workbench" products were created to help teach customers the operation of algorithms in the libraries using visual means. Road networks and geometric data in geographic contexts were used to provide visual familiarity and interest, in effect creating a GIS-like product. In 1997 and 1998 customers asked for a true GIS product based on the workbench products and development of Manifold System was launched. The company soon changed its name to Manifold Software Limited to match the new product's name. Manifold System releases Manifold System was first sold in January 1998 as Release 3.00. Releases 3.00 and 4.00 were heavily weighted to analytics, with many tools for abstract graph theory analysis but a very limited GIS toolset. Release 4.50 emphasized general GIS features of broader interest and emerged as Manifold's first commercial GIS, a typical vector GIS more or less equivalent to classic vector GIS packages such as ArcView 3.x or MapInfo Professional. The Release 5.00 series in 2001 and 2002 integrated display and editing of raster images and surfaces, including terrain elevation surfaces, and both 2D and 3D rendering. The 5.x series also introduced an integrated Internet Map Server (IMS) and the first Enterprise editions of Manifold System allowing collaboration by teams using shared components. The 5.x series also introduced a new spatial SQL and fuzzy logic using the Decision Support System. Releases since 2003 include 5.50, 6.00 (two major feature upgrades via service pack), 6.50, 7.00 and 7x. 6.50 introduced image tiling from Terraserver and OGC WMS image servers using Manifold as a client and extended IMS support to include OGC WMS when using Manifold as a server. 7.00 further extended IMS to include OGC WFS-T and image server functionality as well. Release 7.00 was issued in
