Metadata included with the RNC’s identifies the projection and datum for each chart. The navigation software then converts positioning system information into the chart’s projection and datum in real-time. If a chart’s datum is unknown, the RNC metadata includes the parameters necessary to map geographic positions to RNC pixel locations calculated from the grid intersections printed on the chart.
