Metadata: new metadata for Spectral Ground
Control Points
3/3/2017 Page 7
Department of Geography
Metadata: new metadata for
Spectral Ground Control
Points
- Scaling issues of existing taxonomies: the
CORINE system
- Mismatch between mapping units
3/3/2017 Page 8
Department of Geography
Metadata: new metadata for
Spectral Ground Control
Points
- New taxonomy, loosely based on INSPIRE
- Is it standardised? NO!
- Further gaps and opportunities:
- Aggregation of fine-grained target classes
to link to bigger mapping units
- The aggregation can be taxonomically and
spectrally
- The database can thus be used to
investigate the spectral dynamics related
to target classes and super-classes
