[Qgis-user] Best way to store temperature info

[David Fawcett]

Jorge,

I did a very similar thing with some air modeling data.  The spatial
features were vector 'grid' cells.  I stored these in PostGIS.  For
each feature, there was one data measurement for each day of the year
and some additional aggregated data values.  I stored this data as
related tables in the same database.

To create animations, I used MapServer to create the individual image
slices.  I used a URL variable to pass each individual date in to
MapServer.  MapServer incorporated that value into a query where
condition used to pull data from PostGIS, and then it built the
associated image.

David.
