Title: GIS Software


1
GIS Software Hardware Overview
  • POEC 6381 Introduction to GIS
  • and
  • POEC 6383 GIS Implementation Management
  • Ronald Briggs
  • University of Texas at Dallas

2
Introduction
  • From the discussion of Fundamental GIS Concepts
    we noted
  • two types of data spatial data (where) and
    attribute data (what)
  • two models for data representation raster model
    and vector model
  • two computing environments traditional
    relational data base model and object-oriented
    model
  • as we search for software for our GIS project,
    ideally we seek implementations which
  • handle both spatial and attribute data, and pay
    commensurate attention to each
  • support vector and raster formats, including
  • conversion between the two
  • analytic capabilities for both
  • utilize relational data base or object-oriented
    computing models
  • how do software vendors in the market place meet
    these needs?

3
Software Categorization
  • Professional/industrial
  • capable of supporting on-going operational
    processes and management needs of the enterprise
  • permits programming of business processes and
    geospatial applications
  • Desktop/Presentation
  • support the analytical needs of professionals
    processing geospatial data
  • Business and other Niche Applications targeted
    toward specific subsets of applications
  • to business for site selection and market area
    analysis
  • to specific industries e.g. transportation,
    telecomm, oil gas exploration,
  • to specific applications e.g. rectification,
    thematic mapping
  • Mass Market
  • general public personal productivity
    applications

Professional Desktop versus Mass Market The
capabilities of mass market (display,
single-point geocoding, thematic mapping) plus
  • support for raster as well as vector data (and
    perhaps also images)
  • user-selected (rather than proprietary) spatial
    data input
  • digital format (shape files, TIGER files, etc)
  • geographic format (datum, projection)
  • variety of standard attribute data input formats
    (spreedsheets, comma delimited text, dBase, etc.)
  • external data base access/connectivity via SQL,
    ODBC, etc.
  • internal data customization and query (e.g
    calculating new variables and querying all)
  • selective overlay of input spatial data
  • comprehensive support for spatial query and logic
  • polygon joins and overlay
  • point in polygon
  • intersection of lines and polygons
  • buffering around points, lines and polygons
  • batch geocoding with variety of user-selectable
    options
  • topological editing of input (or new) spatial
    data
  • customization of maps and graphics for display
    and hardcopy
  • variety of digital data output formats for
    graphic (e.g. gif, tif, jpeg) and non-graphic
    data
  • macro, scripting or programming capability

Software for GIS professional/industrial The
Industry Leaders
  • ARC/INFO (ESRI, Inc., Redlands, CA)
  • privately owned by Jack Dangermond, a legend in
    the field and former Harvard prof.
  • originated commercial GIS
  • still clear market leader with about a third of
    the market
  • Intergraph (Huntsville, AL)
  • origins in proprietary CAD hardware/software
  • strong in design and FM (facilities mapping), and
    running hard to match ESRI in GIS
  • its main MGE (Modular GIS Environment) evolved
    from its older CAD products
  • after split with Bentley, committed to developing
    new generation product of its own code named
    Jupiter based on NT and object technology--first
    product (GeoMedia) released March, 1997
  • Bentley Systems (Exton, PA)
  • Bentley brothers (Barry Ray) originally
    developed the PC-based Micro-Station product
    under contract with Intergraph, but split in 1995
  • have very successfully continued to develop and
    sell MicroStation GeoGraphics since then.

GIS Market Share ()
GIS World, July 97, p. 12 quoting Daratech
11
Software Selection Considerations and Trade-offs
  • Price ()
  • you generally pay for capability, but do you need
    it?
  • cost doesnt always equate to capability, but
    theres usually some catch
  • Learning curve
  • simplicity of use for limited function products
  • consistency of interface for multi-function
    products
  • Market share
  • will it be around in the future?
  • experienced workers available
  • third party services add-ons, training,
    consultants, etc.
  • Future needs
  • analytic capabilities
  • data types
  • conversion expensive
  • retraining
  • data conversion
  • application conversion
  • Organizational needs
  • consistent software
  • info sharing
  • lower support training costs
  • lower costs via mass licenses
  • targeted software
  • lower train/support via simpler interface
  • lower cost via targeted function
  • best of both via add-ins or object orientation.

    faster, easier, jazzier way of answering
    council member queries.
  • use ArcView, since city has extensive ArcInfo
    coverages write Avenue scripts to automate most
    common queries
  • Keep the water flowing. Manager for North Texas
    Municipal Water Supply District. Swamped by
    growth. Need help.
  • select Arc/Info with AMLs (or perhaps ArcView
    3.x)
  • Keep the Taxes Coming In. Director of IS for Big
    City. Must tie all my data together--land
    ownership, tax rolls, utility lines, roads, 911
    calls etc. Need enterprise solution.
  • SDE with ORACLE data base

16
Hardware and Platforms for GIS
  • CPU (Intel 486/Pentium, or RISC) must be
    powerful with lots of memory
  • Disk storage lots--especially for images
  • Input devices Digitizer, Scanner, CD-ROM,
    network/Internet
  • Output devices
  • Large, high-res. display (relatively expensive)
  • Wide-bed color plotter (now usually inkjet, and
    affordable)
  • Operating System
  • Windows 3.1/95 and UNIX the most common
  • NT coming on very strong
  • MAC and VMS supported by fewer and fewer vendors
  • Platforms
  • PC or RISC Workstation
  • Mainframe--gone
  • Minicomputer--fading fast (especially VMS based)
  • Networks and Distributed Systems now the norm

    estimated at 35 per year
  • GIS related hardware 0.5 Billion
  • GIS related software 1.1 Billion
  • GIS Consulting services 2.4 Billion
  • The big money is in consulting, not software or
    hardware (although much consulting is software
    related).
