Collection: Plotting Sheets

Universal plotting sheets, also referred to as VP-OS sheets, are used for ocean navigation, and particularly for plotting observed positions obtained by astronavigation. They are nautical charts tailored for use at certain latitudes. The graduated circle at the center allows the creation of meridians of longitude for any latitude. They also help you construct a customized chart for any geographical position. Plotting sheets is an essential tool for navigation courses or for practicing plotting skills.

Available plotting sheets have a Mercator grid for a specific latitude. The grid provides the right ratio between latitude and longitude angular distance, just like the nautical charts used for navigation. National Geospatial-Intelligence Agency nautical charts and plotting charts are available for commercial and recreational mariners. They provide navigational information for international waters and are produced using the latest print-on-demand technology.
