Overview
For a global overview of metadata in Geotk, see the
Metadata page on the project web site.
Bands in gridded data
ISO 19115 defines a Band interface which
expresses the range of wavelengths in the electromagnetic spectrum. For the needs of
Image I/O, an additional interface has been defined with a subset of the Band
API and the restriction to electromagnetic spectrum removed. This interface is defined
in the geotk-coverageio module and is named
SampleDimension.
Both Band and SampleDimension interfaces extend the same parent,
RangeDimension.
Parameterized types
In GeoAPI interfaces, most collections are typed with wildcards, for example
Collection<? extends Citation>. The Geotk implementation removes the
wildcards and declares Collection<Citation> instead. This allows collections
to be live. Consequently it is possible to add new elements directly in
an existing collection using code like getCitations().add(myCitation) instead
than setting the collection as a whole with setCitations(myCitations).
