GIS platforms are probably the most appropriate tool
of introducing geographical information to the end
user, mostly due to the direct perception of space. Thus, depicting the
meteorological stations over the terrain of Epirus, in conjunction with
the rivers and streams, is more effective than the simple representation
of stations in a single level. The GIS platform was considered to be the
main interface of the NDBHMI to the end user, and as a result of this
business rule, a unified environment for connecting to the Database of
NDBHMI was created, for the representation of spatial data and the processing
of timeseries.
One of the main processes implemented in order to be embeded in the NDBHMI GIS
system is the areal integration of timeseries. The application was developed
in an external library and its aim is to fill the gap that GIS systems experience
as far as the representation and management of temporal variables are concerned.
This application was extensively used in the context of the project for the mass
production of mean areal timeseries of rainfall and temperature for various watersheds
and time steps.
