Talk:DAP4: Data Model

From OPeNDAP Documentation

I have a use case of arrays of nested Sequences.

I use the following for multipolygons

In particular,

Sequence { Sequence { Sequence { Float64 lat; Float64 lon; } ring; } polygon; } location[IDIV = 344];

is a set of multipolygons, one for IDIV, a multi-polygon consisting of a number of closed polygons, a closed polygon consists of an outer ring and possibly a number of inner rings (cutouts).

The index is important, because it connects to the rest of the data, i.e. time series for each division stored in a square array. The division has an associated shape, the multi-polygon, which geolocates the time series.
