Looking for your advice and experiences for this one...
We are looking at getting an interactive web page that would allow a user to
insert their coordinates and some other parameters (such as rainfall or
temperature) then run an interpolation routine to generate a map on demand.
We currently use Surfer (Golden Software) to interpolate various data
(rainfall, temperature, crop disease risk, etc) and export a .gif image that
gets posted to the web on a daily basis. This is done in an automated routine
from data in our database through VB. Our webmaster currently uses Cold Fusion
for much of our live web interactions.
In some instances, this may require that the software go to the database and
recalculate values from the beginning of the season (for example, disease risk
values are cumulative). In this case, the data entered and returned would be
stored in our database. In some cases, it will be nothing more than an
ephemeral map that can be printed but which will disappear once the application
is closed. In this case the data need not be saved.
If anyone has done or seen anything like this, some pointers to web pages would
be appreciated, as would advice on your experience with such a service.
Thanks
