In this paper, we continue the discussion about the phenomenon that incorporates two concepts: geoinformation system (GIS) and space. Discussion of our previous works with various experts in computer science, mathematics, philosophy, system monitoring did not change our opinion on this topic. We still believe that the discourse on this subject needs to be conducted from computer science point of view since the expansion of the topic of discussion will lead to a sharp increase in the amount of submitted material and will result in the loss of clarity of the idea that we are trying to convey to the experts. References to philosophical and mathematical sources have been refined after the discussion of the previous paper published in proceedings of IF&IGIS’17 symposium. In this paper, we again emphasise the idea that every abstraction like “point” has its own interpretation and can be represented in different dimensions: 1D, 2D, 3D or nD. We also wish to note that we again base our arguments on well-known concepts of “space” and “time” from the basic university course of linear algebra [1]. In this paper, we specify the relation of these concepts with algebraic analogue of “space” concept from GIS (“point” concept and its generalisations). Specific characteristics and physical parameters of basic concepts like “point” and “space”, their dynamic transformation and variability play an important role for GIS applications. But even more important is the computability of such characteristics using various methods in the interest of the end-user. In this paper, we provide examples of tasks that illustrate our theoretical foundations as a result of computer modelling. We also provide examples of variants of implementation of basic philosophical and computer ideas based on serial products produced by SPIIRAS-HTR&DO Ltd. for more than a decade. This series of products is called “Aqueduct”. |
