Concept of spatial coordinate systems, their defining and implementation as a precondition in geospatial applications

Abstract

There are many users of spatial information, and quite large interest about the nature and genesis of such information. Different users found spatial information in the form of maps, plans or alphanumerical tables. Recently, there are more often in the form of spatial databases, and in the form of geographic information systems. What is behind these spatial data? On what foundation are they designed? In this article we look at the basic aspects of space, dimensionality and global coordinate systems in applications of global geospatial research. Here is explained the definition of the coordinate system as an abstract entity and, consequently, its implementation or establishment in the form of a geodetic reference frame, as real geodetic reference network. The applicative aspect of coordinate systems in this article is emphasized through recommendations and considerations during usage of their different implementations. .

Brojni su korisnici informacija o prostoru, čije je interesovanje o samoj njihovoj prirodi i nastanku, prilično veliko. Same prostorne informacije različiti korisnici pronalaze u vidu karata, planova ili alfanumeričkih tabela. U novije vreme, sve češće u vidu prostornih baza podataka, u obliku geografskih informacionih sistema. Šta stoji u osnovi ovakvih prostornih podloga? Na kakvim temeljima su one zasnovane? U ovom članku se posmatraju osnovni aspekti prostora, dimenzionalnost i globalni koordinatni sistemi u primenama kod globanih geoprostornih istraživanja. Objašnjava se definisanje koordinatnog sistema kao apstraktnog entiteta i posledično, njihova realizacija ili uspostavljanje u vidu geodetskog referentnog okvira, kao realne referentne geodetske mreže. Aplikativni aspekt koordinatnih sistema se u članku apostrofira kroz preporuke i obazrivost u postupku korišćenja njihovih različitih realizacija. .
