1. A system for generating a plurality of thumbnail panels, the system comprising:
one or more controllers including one or more processors configured to execute a set of program instructions stored in a memory, the set of program instructions configured to cause the one or more processors to:
receive a chart data from a chart data vendor, the chart data including at least a geographical information set;
receive an area map from an area map chart vendor, wherein the chart data and the area map depict a similar geographical area, wherein the chart data has a first projection type, wherein the area map has a second projection type different than the first projection type;
generate a plurality of panels based on the chart data, each panel of the plurality of panels including one or more panel corners;
project the one or more panel corners for each panel onto the received area map, the one or more panel corners of the plurality of panels defining one or more corners of a plurality of areas to be extracted;
determine an extraction mapping for each area to be extracted of the plurality of areas to be extracted, the extraction mapping configured to map each area to be extracted to a thumbnail panel of the plurality of thumbnail panels based on the one or more corners of the plurality of areas to be extracted;
extract area map data from each area to be extracted to generate the plurality of thumbnail panels using the determined extraction mapping; and
generate a thumbnail display by combining each thumbnail panel of the plurality of thumbnail panels.
