Digital Mapping, Charting, and Geodesy Analysis Program (DMAP) Technical Review of Tactical Ocean Data (TOD) Levels 0, 1, 2
Abstract
The Tactical Ocean Data (TOD) is a vector-based digital product that portrays seafloor configuration, particularly in areas deeper than 183 meters (100 fathoms) in a format suitable for computerized subsurface navigation. It is intended for use in conjunction with the Digital Nautical Chart (DNC) for complete navigation information. The TOD also functions as a general-purpose global database designed to support Geographic Information System (GIS) applications. This review encompasses specifications for TOD Levels 0, 1, and 2, each of which provides descriptions of the content, accuracy, data format, and design of the respective level of TOD database. In addition, TOD portrays strategic information to support naval operations. Since the TOD is a multi-level product designed to always be used in conjunction with the DNC, the main emphasis of this review is threefold, including: 1) determining if each of the TOD levels are sufficient to be used with DNC alone as an integrated product; 2) determining if the different TOD levels can complement each other in a manner that allows the user to easily transition from one level to the next; and finally 3) identifying if these products work well with other standard and non-standard spatial data products.
