The source input table, source_gatetype, provides the geometrical coordinates of the US and international gates that are spread over three terminals (A, B and C) of an airport.
| id | boundary_coordinates | boundary_name | boundary_attributes |
|---|---|---|---|
| 1 | POLYGON ((10 10, 10 20, 20 20, 20 10, 10 10)) | US Gates | US |
| 2 | POLYGON ((50 50, 50 150, 150 150, 150 50,50 50)) | International Gates | International |
The terminal coordinates are given in the table ref_terminal. All coordinates are in WKT syntax.
| id | boundary_coordinates | boundary_name | boundary_attributes |
|---|---|---|---|
| 1 | POLYGON ((0 0, 100 0, 100 100, 0 100, 0 0)) | Terminal A | A |
| 2 | POLYGON ((100 0, 200 0, 200 100, 100 100, 100 0)) | Terminal B | B |
| 3 | POLYGON ((0 100, 100 100, 100 200, 0 200, 0 100)) | Terminal C | C |
