Considerable effort has been expended in recent years, worldwide, into the definition of appropriate classification systems for monitoring
operations, and the harmonisation of existing class sets. Given the possibilities for the use of images in the production of map data for
many landscape monitoring themes - such as land cover, land use and vegetation - the issue of 'names' is central to the coordination of
remote sensing in monitoring. However, this issue is highly complex, with philosophical, linguistic and political aspects to be considered.
Considerable progress has been made in recent years. Within a programme for increased coordination of Nordic monitoring activities, the
Nordic countries should build upon the recent work, astutely avoiding its repetition or likely pitfalls such as development of a single classification
system. Instead, progress should be made through:
 |
|
increasing knowledge and understanding of the classification systems currently used in Nordic monitoring programmes,
|
|
|
identifying specific nomenclature needs of the Nordic countries, and
|
|
|
gaining experience with the methods, for making correspondence between nomenclatures
|
