Plain English Meaning
An ODP that comes as a picture-style chart instead of just a paragraph of text. It shows the departure path, altitudes, and required climb rates on a single page so the pilot can see exactly how to get out of the airport area while staying clear of obstacles.
Full Definition
Obstacle Departure Procedures published as a charted graphic rather than as a text-only narrative. A graphic ODP shows the departure routing, altitudes, climb requirements, and any obstacle-avoidance instructions on a dedicated chart page, and is identified in the chart title by the suffix '(OBSTACLE)' after the procedure name.
