Land Administration Data to Support Development and Research

The land administration infrastructure is of strategic importance for society and the economy. Due to historical developments, the land administration infrastructure contains many diverse and heterogeneous sources of registers information. The Development of Multipurpose Land Administration System (DEMLAS) project aims to discover what needs to be done to transform land administration from traditional to modern multipurpose systems that support all land development activities. A land administration cyberinfrastructure has been developed to support the research. The cyberinfrastructure - DEMLAS platform includes land administration data (cadastral maps etc.) and public open data, such as land satellite images, historical data, nature data, development data, meteorological data, soil data, etc. Some of this data is obtained from official sources and has the character of private data. Contained within are also links to commercial data, mainly satellite images and orthophotos, but also market related and voluntary data, for instance, OpenStreetMap. The integration of external land administration data is realized using principles of Open Linked Data. The paper presents the development and functionalities of the platform DEMLAS. The open science principles were realized with the concept of user cases that were implemented as one component of the DEMLAS platform. The platform is offering a marketplace where data can be discovered and exchanged with the additional contribution of researchers who can publish their own data or applications based on the data, services and applications already provided.
