The basic principles and operations of spatial data harmonisation

Kročková, K.: The basic principles and operations of spatial data harmonisation. Kartografické listy, 2012, 20 (2).

Abstract: The spatial data harmonisation is theme that is closely related to the data interoperability. Interoperability means activities to eliminate data heterogeneity, which present a big problem nowadays. One of the offered solutions would be building the Spatial Data Infrastructures (SDI). On European level the main activity is concentrated in working on project INSPIRE, which defines required rules for building the infrastructure for Europe region. Not only in Europe but many other countries around the world investigate a lot of time to have their data harmonised in SDI. Defined processes, schemas, rules and other related aspects are standardised on international level to assign interoperability as much as possible. The main goal is to save funds and to prevent duplicity in data production. Somewhere in the middle of this complicated process is data harmonisation that provides transformation between source data sets and target schemas defined by SDI requirements. The most important is correct understanding of basic operations and all possible coming problems before starting the spatial data harmonisation process of data from any domain.
