GIS as a system component
Geographical Information Systems should not be
reserved for specialists with a long training in the field.
By using Rapid Application Development (RAD)
tools such as Borland Delphi and Microsoft Visual Basic combined
with software components, highly usable systems are possible to
A software system can be composed of standard
components for database management, serial communication,
networking, GIS and route-planning/transportation scheduling.
Systems integrators can build highly
sophisticated and usable systems in this way at reasonable costs.
The systems can be trusted for their viability and
Furthermore the flexibility of
component-based development enables the easy compiling of different
versions of the same software for different user categories, e.g.
normal and advanced user.
Transportation flows can be visualised as lines
with thickness based on the amount of material transported. Through
SQL queries that are built easily with the Graphical User Interface
a large amount of data can be quickly analysed by the users.
The same database can be visualised and analysed
in several ways.
