Metadata: new metadata for Spectral Ground

Control Points

3/3/2017


Metadata: new metadata for

Spectral Ground Control

Points

- Scaling issues of existing taxonomies: the

CORINE system

- Mismatch between mapping units

3/3/2017


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

Examples of important Metadata: Target Type and

REF/TGT

Examples of important Metadata: location, UTC,
