[QGIS-Developer] Model for Temporal Measurement (vector) Datasets ?

[Tim Sutton]

Hi Richard

Thanks for clarifying your ideas. Could we not implement something similar
to how WMS-T works in that we have a PostgreSQL-T provider extension for
example that passes a time filter to the underlying data base request. In
another system we are build for a client we have some logic to fetch
min/max/mean/sum/etc from a time slice so we could have something similar
such that each point has only one value for the current time slice.

Not sure if I make myself clear or not...


Regards

Tim
