In this paper, the possibilities of developing the national information infrastructure by applying the Land AdministrationDomainModel (LADM) are discussed. Confirmation of the legitimacy of using the LADM within the (Spatial) Information Infrastructure (SII) context is illustratedwith the case of Poland. Creating the information infrastructure is an immense challenge because its components are ...

Botswana recently embarked on an effort to improve its National Spatial Data Infrastructure (NSDI). This paper takes an example of the country’s effort to improve information for land administration and the problems this effort has had because of a poor spatial data infrastructure.

This paper focuses on the design and development of a Spatial Data Infrastructure (SDI)-compliant online system for air quality information retrieval, including support for real-time monitoring. This system assesses exposure to ambient air to mitigate potential health risks, which is crucial for susceptible individuals, health practitioners and decision makers. Particular attention is paid to t...
