Pub. 109, Atlas of Pilot Charts: Indian Ocean, is the National Geospatial-Intelligence Agency's collection of pilot charts for the Indian Ocean, with one chart for each month of the year. Pilot charts are a classic passage-planning tool, summarizing what conditions have historically been reported at sea in a given month.

On NGA pilot charts such as these, wind roses in each 5-degree square show prevailing winds and calms, and inset charts show tropical cyclone tracks, the percentage of ship reports with gale-force winds, and visibility. Monthly text covers pressure, air temperature, winds and wave heights. Paradise Cay prints this 20-page, 13 x 19 inch atlas on high quality paper.
