Hardware and software requirements for gis

  1. 1. MODULE 1: INTRODUCTION AND DATA STRUCTUREHardware and Software Requirements for GISMany GIS applications are implemented within organizations and have to play animportant role. The effectiveness of GIS projects therefore depends as much onthe futuristic planning of hardware and software requirements.It is therefore necessary to address the question of how GIS can be successful inan organization and continue to do so for many years before upgradations ofhardware and software are needed.GIS projects are successful because they help the organisation to perform betterin society. But it is also true that organisational issues will contribute to the long-term success of a GIS project. In other words, GIS and the host organisation havea close and two-way relationship.It is neither possible nor desirable to recommend here a generalized requirementin terms of hardware and software for a GIS program. Nevertheless, there is anecessity to analyse the requirements keeping in view the following: 1. Organizations goals and objectives 2. Analysis of current practices and problems encountered and redundancies 3. Organizational issues - management structure, resources, staff 4. Training 5. Applications 6. Base map requirements 7. Conceptual data base design 8. System integration 9. Cost of GIS implementation – applications development, data conversion, hardware, software, resources, training, update and maintenance 10.The Strategic Implementation Plan over a period of 3-5 years Sumant Diwakar
  2. 2. MODULE 1: INTRODUCTION AND DATA STRUCTUREHardware RequirementIt is obvious that hardware and software requirements vary considerablydepending on the tasks undertaken. The following minimum configuration allowsinstallation of most modern GIS applications for work with small components.Recommended configurations are noted in parentheses for work with anythingother than small drawings. • 2.8 Ghz Intel i series(i3, i5, i7) true PC compatible (dual-core processor recommended). • 1 GB RAM (4 GB or greater recommended). • 800 x 600 SVGA Display (1280 x 1024 or greater recommended). • 250 MB hard disk free space (gigabytes of free space recommended). • Windows 8, Windows 7, windows Vista, Windows 2000, Windows XP, Windows Server 2003, Windows Server 2008 in standard 32-bit versions or in 64-bit versions. (Windows 7 or greater recommended). • Internet Explorer 9 or most recent IE version plus most recent service pack. • Microsofts .NET Framework 4.0 or more recent. • IIS 5.1 or greater to operate IMS.· For very large tasks, such as intensive web server applications using IMS, investing in a dual socket, quad processor machine may be considered. This has eight cores. Various processes within modern GIS applications can use multiple processors. Sumant Diwakar
  3. 3. MODULE 1: INTRODUCTION AND DATA STRUCTURESoftware RequirementThe following is a list of GIS application packages from which one can choose. Thechoice shall depend on the needs of the organization, functionality desired andthe money available, and the period for which the planning is being done. Onemay need to make a comparison of costs and benefits (both of which keepchanging rapidly) before making a final decision.Most widely used notable proprietary software applications and providers: • Hydro GeoAnalyst – Environmental data management and visualization software by Schlumberger Water Services. • Autodesk – Products include MapGuide and other products that interface with its flagshipAutoCAD software package. • Cadcorp – Developers of GIS software and OpenGIS standard (e.g. Read/Write Open Source PostGIS database). • Intergraph – Products include GeoMedia, GeoMedia Profesional, GeoMedia WebMap, and add-on products for industry sectors, as well as photogrammetry. • ERDAS IMAGINE – A proprietary GIS, Remote Sensing, and Photogrammetry software developed by ERDAS, Inc. • ESRI – Products include ArcView 3.x, ArcGIS, ArcSDE, ArcIMS, and ArcWeb services. • IDRISI – Proprietary GIS product developed by Clark Labs. • MapInfo – Products include MapInfo Professional and MapXtreme. integrates GIS software, data and services. • MapPoint – Proprietary GIS product developed by Microsoft. • GISNet – A web-based GIS system developed by MRF Geosystems Corporation. • Caliper – Products include Maptitude, TransCAD and TransModeler. Develops GIS and the only GIS for transportation. • Pictometry – Proprietary software which allows oblique images to be draped with shapefiles. Many govt applications (fire, 911, police, assessor) as well as commercial. • Black Coral Inc — a leading edge product company developing geospatial collaboration capabilities that enable better outcomes for personnel and tactical teams operating in emergency response and military environments.
