With growing concerns about environmental problems, and an exponential increase in computing capabilities over the last decade, the geospatial community has been producing increasingly voluminous and diverse geographical datasets. Long-term preservation of these geographical data exposed through uniform and interoperable Spatial Data Infrastructures (SDIs) is not typically addressed, but highly important for meeting legislative requirements, the short and long term exploitation of archived data as well as efficiency savings in managing superseded datasets. In this paper, we attempt to set out the path and describe what needs to be done now to future-proof the investment government agencies around the world have made in digital geographic data. We take the INSPIRE SDI as an exemplar to investigate the requirements for ensuring sustained access to geographical data from the perspective of a preservation-aware and INSPIRE-conformant SDI. We also outline a number of principles for the long term retention and preservation of European digital geographic information defined by the EuroSDR Geographic Data Archiving working group. In addition, we present a preservation profile of the ISO 19115 metadata standard to enable recording and exposing important preservation related information about geographical data through large-scale SDIs like INSPIRE.

This paper states 16 principles for the long term retention and preservation of digital geographic information. The paper is mainly aimed at public sector geographic information providers in Europe (particularly those involved in mapping and cadastre) with the intention of highlighting the significance of fundamental concepts for digital geographic data archiving. Geographic information providers are mainly mapping agencies, but also archives preserving geographic data among a wider range of digital information. A supplementary objective is that the paper may provide useful information for providers of all types of geographic information right around the world. This paper states 16 principles for the long term retention and preservation of digital geographic information. The paper is mainly aimed at public sector geographic information providers in Europe (particularly those involved in mapping and cadastre) with the intention of highlighting the significance of fundamental concepts for digital geographic data archiving. Geographic information providers are mainly mapping agencies, but also archives preserving geographic data among a wider range of digital information. A supplementary objective is that the paper may provide useful information for providers of all types of geographic information right around the world. There are many reasons why people wish to retain access to information, though the main drivers for archiving digital geographic information are meeting legislative requirements, the short and long term exploitation (re-use not only access) of archived data for analyzing social, environmental (e.g. global climate changes) and economic changes over time as well as efficiency savings in managing superseded datasets. This paper sets out the path and describes what needs to be done now to future-proof the investment government agencies around the world have made in creating digital Geographic Data.
