Thanks for your answer Jacob, much appreciated.
The way I'd like to organise my information is as follows:
The Spanish Institute of Ports publishes wind and wave prediction charts like the one you can see here:
Barcelona chartThese charts are updated about 4 times a day by them.
What I want to do is take the data in these charts, transform the data into another layout and then publish that layout with the data in them when the visitor clicks on the link from the city or rather port he wants information about.
So the complete process would be:
1. Visitor clicks the link or button of a specific port.
2. That click generates a request to the relevant chart.
3. The data from the chart are used to recalculate some values (e.g. meters per second for the wind speed is transformed into knots)
So the amount of requests is really limited, and certainly not constant and must all be manually triggered
4. The recalculated data are fed into a customized layout and displayed
I might add some graphical elements, e.g. a wind vane that turns quicker when wind speed increases, but those wouldn't generate any requests either since these would use data that are already retrieved.
Do you think that would be allowable?
Thanks in advance for your answer.
