/**
 * Glimpse has preliminary support for displaying Electronic Navigation Chart
 * raster images available in the BSB Raster format directly from NOAA.
 *
 * Chart files which can be directly loaded and displayed by Glimpse are
 * available from the following website: http://www.charts.noaa.gov/RNCs/RNCs.shtml
 *
 * Note that currently Glimpse does not automatically project the image correctly
 * (it is being displayed here as a flat image). This capability is in development.
