digital nautical chart
MapMedia mm3d Vector Charts utilize a vector database to build the chart display. This data is stored in layers and records every nautical chart feature such as coastlines, buoys, lights, etc. These features and their attributes such as position, color, size, shape, and others are stored in a database that allows them to be selectively displayed and interrogated.
Vector charts are extremely accurate at their reference scales (as long as they are not “over-zoomed”), but can appear quite different from traditional paper charts. MapMedia mm3d Vector Charts allow you to customize your chart display.
