Hardware and Software Requirements for GIS
Many GIS applications are implemented within organizations and have to play an important role. The effectiveness of GIS projects therefore depends as much on the futuristic planning of hardware and software requirements, as on technicalities of its implementation. It is therefore necessary to address the question of how GIS can be successful in an organization and continue to do so for many years before upgradations of hardware and software are needed. GIS projects are successful because they help the organisation to perform better in 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 have a close and two-way relationship.
It is neither possible nor desirable to recommend here a generalized requirement in terms of hardware and software for a GIS program. Nevertheless, there is a necessity to analyse the requirements keeping in view the following:
It is obvious that hardware and software requirements vary considerably depending on the tasks undertaken. The following minimum configuration allows installation of most modern GIS applications for work with small components. Recommended configurations are noted in parentheses for work with anything other than small drawings.
· 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.
Memory Requirements for Large Projects - Manifold is designed for an era where RAM memory is cheap and personnel costs are high. Undo and many other user-friendly features require a lot of memory to implement. For best performance we recommend installing lots of RAM and having plenty of free disk space for temporary files. RAM is so cheap in modern times it is "penny wise and pound foolish" not to load up your system with the maximum amount of RAM it can hold. This will help all your work go faster and not just Manifold. As always, keep in mind that to really use lots of RAM effectively you should be running 64-bit Windows such as Windows Vista x64, Windows Server 2008 x64 or Windows XP x64.
The following is a list of GIS application packages from which one can choose. The choice shall depend on the needs of the organization, functionality desired and the money available, and the period for which the planning is being done. One may need to make a comparison of costs and benefits (both of which keep changing rapidly) before making a final decision.
