Abstract
A method is described for generating a navigation chart. The navigation chart includes a plurality of allocated areas corresponding to symbols for a plurality of chart features. The method includes identifying an unallocated area of the navigation chart proximate to a symbol for one chart feature of the plurality of chart features. A first label and a second label are determined for the one chart feature. The first label includes a plurality of feature attribute indicators, and the second label includes a subset of the plurality of feature attribute indicators. A label is selected from among the first label and the second label based on dimensions of the unallocated area. At least a portion of the unallocated area is allocated to the selected label, and the navigation chart is displayed.
