• U.S. military was developing raster
• based capabilities associated with satellite imagery &air photo
• The popular and freely distributed package GRASSdeveloped by Army Corps of Engineers is an example
• Today, the on-going development of GRASSsoftware is a collaborative project between publicand private sector users, as well as university-based researchers.
• Military developments has slowly made it to thecommercial market

Software for GIS: The Main Players
• ESRI, Inc., Redlands, CA• clear market leader with about a third of the market• originated commercial GIS with their ArcInfo product in 1981• privately owned by Jack Dangermond, a legend in the field • Strong in gov., education, utilities and business logistics
• MapInfo, Troy N.Y.• Aggressive newcomer in early 1990s, but now well-established.• Strong presence in business, especially site selection & marketing, and telecom
• Intergraph (Huntsville, AL)• origins in proprietary CAD hardware/software• Older UNIX-based MGE (Modular GIS Environment) evolved from CAD • Current GeoMedia was the first true MS Windows-based GIS• strong in design, public works, and FM (facilities management), but weakening
• Bentley Systems (Exton, PA)• MicroStation GeoGraphics, originally developed with Intergraph, is now their exclusive and
main product..• Strong in engineering; advertises itself as “geoengineering”
• Autodesk (San Rafael, CA)• Began as PC-based CAD, but now the dominant CAD supplier• First GIS product AutoCAD Map introduced in 1996• Primarily small business/small city customer base
The main two “pure GIS”
companies.

Software for GIS: other players
Vector GIS• Smallworld Systems
(Englewood, CO)• first to use OO (early ‘90s),
but failed to compete as established vendors did same
• Purchased by GE in 2000
• emphasis on FM & utilities
• Manifold (CDA International Corp):
• low cost, but low market share
• Maptitude(Caliper Corp, Newton, MA):
• another low cost one
Raster GIS• ERDAS/Imagine
– long established leader– acquired by Leica Geosystems in 2001
• ER MAPPER– aggressive newcomer originating in Australia
• Envi,– relative newcomer, radar specialization– acquired by Kodak in 2000
• PCI--Geomatica – long-term Canadian player
• CARIS – newer Canadian entry
• GRASS (Rutgers Univ.)– Classic old-timer originally developed by US
Army Construction Engineering Research Lab(CERL) in Champaign, IL;
– army ended dev. & support in 1996 but assumed by Baylor University.
• IDRSI (Clark Univ)– pioneering, university-developed package

ESRI Product Line-up: ArcGIS client products (Fall 2007)
ArcReader (“adobe acrobat” for maps) & ArcExplorer (spatial data viewer) • Free viewers for geographic data.
ArcGIS 9.x Desktop: two primary modules (MS only)1. ArcMap: for data display, map production, spatial analysis, data editing2. ArcCatalog: for data management and previewArcToolbox, for specialized data conversions and analyses, available as a window in both
Available capabilities within these modules are “tiered” in three levels• ArcView: viewing, map production, spatial analysis, basic editing:• ArcEditor: ArcView, plus specialized editing:• ArcInfo: ArcView & ArcEditor plus special analyses and conversions:
Extensions: for special apps.: Spatial Analyst, 3D Analyst, Geostatistics, Business Analyst, etc.ArcObjects: to build specialized capabilities within ArcMap or ArcCatalog using VB for Applications
ArcGIS Workstation (for UNIX and MS)• the old command line ArcInfo 7.1
ArcGIS Engine (MS NT/2000/XP)• Set of embeddable GIS components (ArcObjects software objects) for use in building custom
applications• Runs under Windows, Unix and Linux, with support for Java, C++, COM and .NET• Replaces MapObjects which were based upon a previous generation of GIS objects
Notes:ArcView 3.3 the only GUI option for UNIX.ArcGIS 8 released 2000 to integrate two previous standalone products: ArcView and ArcInfoArcGIS 9 released 2004 providing the full capability that should have been in ArcGIS 8!!!
--full support for all data types (coverages, shapefiles, geodatabases)--full support for all previous geoprocessing analyses --Modelbuilder for scripting and repetitive processing--ArcEngine for building custom applications 26

ArcGIS Server: three tiers of capabilityData services: ArcSDE (Spatial Database Engine)
• middleware to support spatial data storage in standard DBMS on server • Supports all major industry databases:
• Oracle, SQL-Server, IBM DB2, IngresMap services: ArcIMS (Internet Map Server)
• Provides maps and simple query to a user without a desktop GIS• Accessed via web interface
Analytic services: • Permits the creation of server-based specialized GIS applications• Provides full range of GIS capabilities to a user without a desktop GIS • Accessed via web interface
(prior to 9.2 these were sold as three separate products)
ArcGIS On-line Services• On-line services made available on the Internet with a subscription• Normally charged on a “per transaction” basis, but can be flat fee
• built and operated by ESRI (or other others), usually based on ArcGIS Server

1. These products have the same interface and share much oftheir functionality. ArcEditor does everything ArcView does andgoes beyond it; ArcInfo does everything ArcEditor does andgoes beyond it
2. ArcEditor can create and edit certain spatial data formats, butArcView can not
3. ArcInfo can edit more spatial data formats, with a ArcInfoworkstation together

ArcCatalog is used to browse,organize, distribute anddocument your GIS data.Geoprocessing can also beperformed.ArcMap is used to create, view,query, edit, compose andpublish mapsArcToolbox is for processingand analyzing your data. It isnow an integrated part ofArcMap and ArcCatalog thatappears as a dockable window

Basic, Standard, and Advanced (formerly ArcView, ArcEditor, andArcInfo) are licensing levels for ArcGIS for Desktop applications.
Basic provides data visualization, query, analysis, and integrationcapabilities along with the ability to create and edit simplegeographic features.
Standard includes all the functionality of Basic and adds acomprehensive set of tools to create, edit, and ensure thequality of your data.
Advanced includes all the functionality of Standard and addsadvanced spatial analysis, data manipulation, and high-endcartography tools.
ArcMap and ArcCatalog are the core applications delivered withall licensing levels of ArcGIS for Desktop; ArcScene and ArcGlobeare part of the ArcGIS 3D Analyst extension.
