As of April 15, USACE stopped providing updates to S-57 chart data set. All inland updates are now provided only for the IENC 2.2 data. PolarView 1.9.7 has been released and addresses this issue. Users are advised to upgrade to most recent version of PolarView NS to restore USACE inland chart support.
Note that the new USACE chart set used different naming convention. These charts will not replace the original USACE charts that were previously installed. You should manually delete previously installed USACE charts (names beginning with “U35”) prior to downloading these charts.
