The SEDRIS Data Representation Model
APPENDIX A - Classes Spatial Index Data |
|---|
An instance of this DRM class specifies the row and column indexes of a cell within a regular spatial relationship of cells. <Spatial Index Data> link objects are used within spatial index related aggregations to distinguish sibling branches of the aggregations. The indexes for row and column are one-based.
Given the origin of the spatial index related aggregation and the row and column widths defined by that aggregation, the location of any cell is determined from its <Spatial Index Data> link object.
See <Spatial Index Related Features>, <Spatial Index Related Geometry>, <Spatial Index Related Feature Topology>, and <Spatial Index Related Geometry Topology> for examples.

The row_index field specifies the row within the spatial index related aggregation to which the specified cell belongs.
The column_index field specifies the column within the spatial index related aggregation to which the specified cell belongs.
