The columns in the table that Tessellate_Search returns are as follows.
|Column Name||Data Type||Description|
|out_key||DECIMAL(18,0)||A copy of the in_key input argument.
The data type of out_key matches the data type of the in_key argument.
|cellid||INTEGER||The INTEGER value that is returned codes for the cell number and level. The upper 28 bits identifies the cell number, and the lower four bits identifies the level. Use:
cellid / 16
to derive the cell number and:
cellid MOD 16
to derive the level.
Cell IDs are numbered from left to right, 0 to n-1, where n = g_nx * g_ny. Cell 0 is in the lower left corner. Here is an example that shows the cell numbering of a single-level grid (of unspecified size) that contains 16 cells.
