Some lawyers consider the application of real environmental qualitiy standards to be legally required. Influence of Computer Science Chapter 4 shows opportunities and limitations of the use of computers, esp. Thus, impacts may be identified only due to computer support. On the other hand, nonsense can be both accelerated and sophistically presented by putting inadequate methods on garbage data. Use of technical support always influences methods and results.
Use of computers leads to investigation of more parameters or alternatives.
It may also lead to better quality. And it leads to a higher investment of time in the presentation of the output, often without justification of the investment by the output. In addition, the use of GIS and XPS forces the discipline to better structure and formalize methods. This will not necessarily be a disadvantage as it may lead to more comprehensible methods by avoiding intuitive and little reflected judgements. Mathematical or statistical artefacts may result instead, e.g. in the definition of classes.
