Multiple Coverage Entries for a single Tile Matrix Set #30

Closed bosborn closed 8 years ago

bosborn commented 8 years ago

Currently the schema allows for multiple rows in the gpkg_2d_gridded_coverage_ancillary table foreign keying on tile_matrix_set_name to the same gpkg_tile_matrix_set row. Does this make sense to have multiple coverages for a single Tile Matrix Set?

If not, should add a unique constraint on the gpkg_2d_gridded_coverage_ancillary table tile_matrix_set_name column.

It does not make sense to have multiple coverages for a single Tile Matrix Set. I agree with adding a unique constraint on the gpkg_2d_gridded_coverage_ancillary table tile_matrix_set_name column.
