Comparative GIS analysis using taxonomy and classification techniques

The article discusses the methodology of comparative analysis of GIS class computer systems using the current elements of taxonomy and classification theory. Eighteen selected GIS class systems that meet the criterion of completeness of all data required in the conducted research were fully analyzed. The proper comparative characteristics were preceded by the recognition of the market situation in terms of the availability of GIS systems. Eight thematic groups of criteria were used in the research, based on which the selection of GIS solutions for comparison was carried out. The adopted system selection criteria carry out the selection of objects in a binary manner. The chosen rules of classifying the system into a set of objects for comparison covered the issue of the availability of the required information. Due to the characteristics carried out, this information was obligatory, because a full set of data is required, which will allow for a comprehensive and factual comparison, based on which a given product (GIS system) can be indicated to the consumer with full responsibility. The set of features and comparative criteria was created based on own experience and numerous consultations with specialists and field experts. The selected criteria are the most widely used and most accepted in the environments that systems of this class use daily. Both the functional scope (features, functions, properties, advantages and disadvantages) as well as the degree of fulfillment of subsequent criteria by the considered systems were determined and described.
