Modular-Hierarchical Phase: classifiers and attributes
• Land Cover Classifiers are hierarchically arranged according
to mapability, i.e. geographical accuracy, at the top levels.
• Environmental Attributes are not hierarchically arranged and
are shown at the intermediate levels.
• Specific Technical Attribute is shown at the bottom.

Modular-Hierarchical Phase: classifiers in detail
The classifier Life Form
is used to illustrate
some features.
The options of the classifier are mutually exclusive, i.e. the user
can select only one option.
Furthermore, this particular classifier has a more general level
comprising Woody, Herbaceous and Lichens/Mosses, followed by
a more specific level comprising Trees and Shrubs, Forbs and
Graminoids, and Lichens and Mosses.
There are also options that further modify a classifier option,
the so-called Modifiers and they immediately follow a classifier
option (e.g. for Forbs Rooted and Free-floating in bright blue).
Classification Module
Modular-Hierarchical Phase: modifiers in detail
The Modifiers further modify a classifier option and they
immediately follow a classifier option.
The selection of Modifiers is optional!
The use of Modifiers will generate:
• a separate Boolean Formula;

Legend Module
How to add User-defined Attributes?
Land cover classes can be “cloned” in order to add specific userdefined attributes to the standard class. A user may want to
further define a classifier and/or attribute already used, or
add a new attribute. A standard set of clone options is provided.
The Type of Clone to be made is
selected in this window. The result is a
code added to the Boolean code (e.g.
(1) in the example above)
The userdefined
code is
specified
in this
window
as well as
its
meaning.
Legend Module
Edit and Display
Display of a created Legend shows a standardized hierarchical
order with the classes under their Structural Domain within the
main land cover type.
Edit allows the user to add
a User’s Label that may be
a common name or a name
derived from an existing
legend.
Furthermore, Description
can be used to add more
information on the class.
In this example
each class has
a User’s Label
that will also be
shown in
Display.
Legend Module
Standard Description
The Standard Description for each land cover class gives the
user a better insight into the classifiers used and structure of
the class than can be inferred from the standard name alone.
Classes are hierarchically ordered according to Structural
Domains of the main land cover types.

Legend Module
Classifiers Used
This option gives the user the
possibility to interpret what the
codes of the Boolean Formula of
the land cover classes mean.
Combination of numerical codes
and Boolean Formulae will allow
GIS users to re-select LCCS
data.
The Classifier Code and its Label are displayed.
Please note that codes can appear more than once
with a different meaning ! Therefore the code
should always be combined with the numerical
code of the class to form a unique combination.
