Border region structures
The aim of this analysis is to follow theoretically the way, how a border area becomes an integrated, well-functioning border zone. The definitions and classifications lead up to the concepts of cross-border space generally constructed in the 1990’s, in the works of Ratti, Renard or Sanguin. The spatial organization of cross-border regions is generally represented in schematic maps, including more or less objects (border line, rivers, roads, railroads, canals, cities and other settlements, etc.) and flows (capital, labor-power, tourists, migration, etc.). Maps for different border types and levels of cross-border cooperation use different elements and seem not comparable. We summarize these different maps and suggest some modifications and extensions, offering a more general tool for the theoretical analysis. The IT age partially changed the channels of communication; thereby the update of the models is current.
