Caliper Corporation was founded in 1983 as a developer of mapping software and is headquartered in Newton, Massachusetts.
Caliper develops geographic information systems (GIS) and transportation software. Caliper is also a consulting and R&D provider offering professional services in quantitative management consulting, transportation, and decision support systems development.
Caliper is the developer of the TransCAD transportation planning software, TransModeler traffic simulation software, and Maptitude [1] GIS packages.
TransCAD is software for transportation planning. In addition to the standard point, line, area, and image layers in a GIS map, TransCAD supports route system layers and has tools for creating, manipulating and displaying routes. TransCAD uses a network data structure to support routing and network optimization models. TransCAD includes trip generation, distribution, mode choice, and traffic assignment models that support transportation planning and travel demand forecasting. TransCAD has a set of dynamic segmentation and linear referencing tools for managing highway, rail, pipeline, and other networks. [2]
TransCAD was first released as a MS-DOS-based transportation GIS package in 1985. TransCAD 3.0, the first Microsoft Windows version, was released on May 28, 1996. TransCAD 4.8 was replaced by TransCAD 5.0 on January 2, 2008, and later TransCAD 6.0 and TransCAD 7.0. The most current version is TransCAD 8.0.[ citation needed ]
TransCAD for the Web is a web-based version of TransCAD that uses application source code that can be edited using Javascript, HTML, and ASP.NET. Application templates (Mapplications) are used to create a web application or service. The default templates include Ajax applications and mashups that use Google Maps via the Google Map API. TransCAD for the Web was the first web-based GIS for Transportation (GIS-T), [3] [4] and remains the only transportation GIS with web development capabilities. [5]
Maptitude for Redistricting is a related, but separate product, to Maptitude. By 2001, Caliper's new redistricting mapping technology was being used by over fifty percent of the United States's legislatures to draft new electoral district boundaries following the 1999 census. [6] In 2011, California established a citizens redistricting commission that used Maptitude to successfully redraw the maps. [7]
AutoCAD is a 2D and 3D computer-aided design (CAD) software application developed by Autodesk. It was first released in December 1982 for the CP/M and IBM PC platforms as a desktop app running on microcomputers with internal graphics controllers. Initially a DOS application, subsequent versions were later released for other platforms including Classic Mac OS (1992), Microsoft Windows (1993) and macOS (2010), iOS (2010), and Android (2011).
A geographic information system (GIS) consists of integrated computer hardware and software that store, manage, analyze, edit, output, and visualize geographic data. Much of this often happens within a spatial database, however, this is not essential to meet the definition of a GIS. In a broader sense, one may consider such a system also to include human users and support staff, procedures and workflows, the body of knowledge of relevant concepts and methods, and institutional organizations.
BRL-CAD is a constructive solid geometry (CSG) solid modeling computer-aided design (CAD) system. It includes an interactive geometry editor, ray tracing support for graphics rendering and geometric analysis, computer network distributed framebuffer support, scripting, image-processing and signal-processing tools. The entire package is distributed in source code and binary form.
In computing, GeoServer is an open-source server written in Java that allows users to share, process and edit geospatial data. Designed for interoperability, it publishes data from any major spatial data source using open standards. GeoServer has evolved to become an easy method of connecting existing information to virtual globes such as Google Earth and NASA World Wind as well as to web-based maps such as OpenLayers, Leaflet, Google Maps and Bing Maps. GeoServer functions as the reference implementation of the Open Geospatial Consortium Web Feature Service standard, and also implements the Web Map Service, Web Coverage Service and Web Processing Service specifications.
A GIS software program is a computer program to support the use of a geographic information system, providing the ability to create, store, manage, query, analyze, and visualize geographic data, that is, data representing phenomena for which location is important. The GIS software industry encompasses a broad range of commercial and open-source products that provide some or all of these capabilities within various information technology architectures.
A Web Map Service (WMS) is a standard protocol developed by the Open Geospatial Consortium in 1999 for serving georeferenced map images over the Internet. These images are typically produced by a map server from data provided by a GIS database.
Spatial network analysis software packages are analytic software used to prepare graph-based analysis of spatial networks. They stem from research fields in transportation, architecture, and urban planning. The earliest examples of such software include the work of Garrison (1962), Kansky (1963), Levin (1964), Harary (1969), Rittel (1967), Tabor (1970) and others in the 1960s and 70s. Specific packages address their domain-specific needs, including TransCAD for transportation, GIS for planning and geography, and Axman for Space syntax researchers.
ArcGIS is a family of client, server and online geographic information system (GIS) software developed and maintained by Esri.
Smallworld is the brand name of a portfolio of GIS software provided by GE Digital, a division of General Electric. The software was originally created by the Smallworld company founded in Cambridge, England, in 1989 by Dick Newell and others. Smallworld grew to become the global market leader for GIS in 2010 focused on utilities and communications and remains strong in this sector today. Smallworld was acquired by GE Energy in September 2000.
