Data analysis
Data analysis is the most important feature of ILWIS, qualifying it as an analytical
GIS package. Data analysis is the process in which you generate information that is
useful for solving a particular problem. When the data is in the form of satellite
images, the data analysis is also called digital image processing. The objective is to
generate images that can be interpreted by experts, or to generate classification
results, containing thematic information on features such as land use, lithology, etc.
The various ILWIS operations on image processing will be covered in chapter 6.
Other data analysis techniques dealing with maps, combined with tables, will be
treated in the chapters 7 to 12 which have an increasing degree of complexity.
