| 3 | | Used to compute the valid vertices (corners) of an image. Defines a polygon - inside the polygon are valid sampled pixels outside are nulls. Scans the image, extracts vertices and writes results to a keyword list. |
| 4 | | Name of the keyword list is the image_file with"_vertices.kwl" appended. |

| | 3 | Used to compute the valid vertices (corners) of an image. The valid verticies are defined as a 4 point polygon. Inside the polygon are valid sampled pixels outside are nulls. Results are saved to a keyword list. |

| | 5 | Name of the keyword list is the image_file with"_vertices.kwl" appended. So if image = "foo.tif" then results file = "foo_vertices.kwl". |
