Application of a Geographic Information System (GIS) for mapping railway networks. Methodological proposal

Abstract

The interoperability of a unified information system challenges data management and communication in the same format. The Argentinian railway is going through a moment of modernization, which is why it is essential to have a set of precise data about its network. The diversity of sources merits the development of an objective criteria on the collection of that information. Thus, the use of GIS is presented as a suitable tool to accompany this process, providing great advantages for planning. This article proposes a methodology for information management and concludes with the pertinence of homologating and establishing a unifying criterion of data when designing a GIS design. The work consists of two sections: one of them is focused on the substantial sources for working with railways GIS and the other presents the model proposed by the authors.
