The Geographical Vector Interpretation System (GeoVis) (see figure
below) is a vector-based editing system specifically designed
for thematic interpretation. Hence, it facilitates and speeds
up all mapping activities based on remote sensing data.
It is a user-friendly system that embeds the main tools of vector drawing
and editing, including topological functions, with advanced
capabilities of raster management and a direct link with LCCS
(Land Cover Classification System).
The GeoVis software has been developed by the Italian software
Terranova. The live-link with LCCS makes it possible to
immediately assign a specific land cover class to a polygon.
The resulting classified vector map is a final product and can
be exported to e.g. ESRI-ArcView to perform further GIS based
manipulation or modelling.
GeoVIS is property of FAO and as such is available only for UN Agencies,
Organizations and National institutions dealing with FAO. Users not
belonging to and not dealing with such organizations are not allowed
to use GeoVis.
If you are an FAO partner you can use GeoVIS as freeware. You can
download your free copy of the software and request FAO Africover for
a software key. Thus, you shall be required to provide us with the
registration number that appears after installing the software; we
will then provide you with the relevant software key.
