ADG is a cross-cutting interrogation software that allows the easy and
fast recombination of land cover polygons according to the individual
end-user requirements. Aggregated land cover classes can be generated not
only by name, but also using the set of existing classifiers.|

Most of ADG functionalities are grouped in four sections/phases:
The group SELECTION supports
users with different modalities for selecting polygons, either interacting
with the map view ('selection by rectangle' in linked figure) or doing
a "theme on theme" selection by using areas coming from a diffent
- CHECK UP (legends/reports)
-Display ADG legend
- APPLICATION (Ratios/Points Identify)
The group CHECK UP includes
functions that allow users to check and visualize land cover data according
to the LCCS legend (linked figure shows list of classifiers).
Different map and report visualizations can be run.
The group ANALYSIS allows
users to create (linked figure shows step in creating new class), edit,
AND apply an ADG legend as well as the layer statistics, and also provides
The group APPLICATION collects
modules performing specific analyses on the data. Currently, grid ratios of
land cover classes (example in linked figure) and points identify
are the available analyses.
Connecting to ADG Server
ADG uses land cover data with an LCCS legend. These data can be local, or can
be dowloaded from a remote server.
The characteristic of this functionality is that ADG has to be installed
on an Internet-enabled workstation, and that ADG compliant land cover data
have to be published on a server accessible through the HTTP protocol.
FAO has recently published Africover aggregated land cover data on its
server, ready to be displayed into ADG software. To do so, please insert the following
URL in the address box of the Server Connection window, and connect to
it. The example above refers to the Tanzania database.
