Obsea web: Design and implementation
| Instrumentation Viewpoint
In this paper we present the steps followed in order to do the design of the
OBSEA project website, and also the technologies and mechanisms used to process
and show the data acquired by the observatory. One of the main bases of our work
plan was to take into account the destination public who the website is addressed
to, both general public and scientists or engineers must find interesting contents.
For the construction of this website we have used commercial programs and applications.
