RE: [Qgis-user] Best way to store temperature info
I think Jorge wants to store data just at a single point (not a full raster). Any QGIS datasource would do: sqlite, PostgreSQL, etc. sqlite is easier to exchange with other people, Postgis makes more sense in a centralized multiuser environment. Both have good performance and SQL capabilities, PostgreSQL is of course more powerful. Netcdf would definitely be overkill if one stores temperature values just at a single point.

Quite true, what I want to ultimately do is an animation of temerture variations in several areas I was thinking in making a related table to store temepratures for points and areas indexed by date. thanks On Tue, 28 Jun 2011 17:45:09 +0200, Andreas Neumann wrote: I think Jorge wants to store data just at a single point (not a full raster).

Re: [Qgis-user] Best way to store temperature info
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.
