  <\/span>🔎 The NOAA ENC catalog: what is it?<\/span><\/h2>\n\n\n\n
  The NOAA (National Oceanic and Atmospheric Administration)<\/strong> provides an official catalog containing several thousand ENC cells covering:<\/p>\n\n\n\n
  - inland waterways.<\/li>\n<\/ul>\n\n\n\n
    Each ENC cell is described by:<\/p>\n\n\n\n
    \n
    a unique identifier (e.g. US5NYCDF<\/em>),<\/li>\n\n\n\n
    a purpose<\/strong> (usage level, from overview to very high detail),<\/li>\n\n\n\n
    a nominal scale,<\/li>\n\n\n\n
    a precise geographic extent,<\/li>\n\n\n\n
    an official download URL.<\/li>\n<\/ul>\n\n\n\n
    Until now, accessing this catalog required external tools or manual searches.
    The NOAA module in S57Manager<\/strong> completely changes this workflow.<\/p>\n\n\n\n
    \n\n\n\n<\/span>🧩 A NOAA module fully integrated into S57Manager<\/span><\/h2>\n\n\n\n
    The new NOAA module is fully integrated into S57Manager and follows its core philosophy:<\/p>\n\n\n\n
    \n
    centralize all ENC-related tools in a single, coherent and efficient interface.<\/strong><\/p>\n\n\n\n
    $\"\"$ <\/a><\/figure>\n<\/blockquote>\n\n\n\n
    From QGIS, users can now:<\/p>\n\n\n\n
    \n
    load the official NOAA catalog (XML),<\/li>\n\n\n\n
    browse the complete list of available ENC cells,<\/li>\n\n\n\n
    dynamically filter the catalog,<\/li>\n\n\n\n
    import only the cells that are truly relevant.<\/li>\n<\/ul>\n\n\n\n
    \n\n\n\n
    <\/span>🎛️ Filters designed for real cartographic workflows<\/span><\/h2>\n\n\n\n
    The NOAA module provides several combinable filters<\/strong>.<\/p>\n\n\n\n
    $\"\"$ <\/a><\/figure>\n\n\n\n
    <\/span>🔹 Filtering by purpose<\/span><\/h3>\n\n\n\n
    NOAA ENC cells are classified by purpose (1 to 6):<\/p>\n\n\n\n
    Purpose<\/th> Usage<\/th><\/tr><\/thead>
    1<\/td> Overview<\/td><\/tr>
    2<\/td> General<\/td><\/tr>

    Users can precisely select the desired usage levels.<\/p>\n\n\n\n
    \n\n\n\n
    <\/span>🔹 Filtering by scale<\/span><\/h3>\n\n\n\n
    Each ENC cell has a nominal scale (e.g. 1:10,000; 1:50,000).
    The module allows defining minimum and maximum scales to avoid loading:<\/p>\n\n\n\n
    \n
    overly generalized data,<\/li>\n\n\n\n
    or excessively detailed data.<\/li>\n<\/ul>\n\n\n\n
    💡 Tip:<\/strong>
    Purpose 5 and 6 cells typically use very fine scales (\u2248 1:2,000 to 1:12,000).
    To display them correctly, it is recommended to set the minimum display scale around 1:1,500<\/strong>.<\/p>\n\n\n\n
    \n\n\n\n
    <\/span>🔹 Filtering by QGIS map canvas extent<\/span><\/h3>\n\n\n\n
    This is one of the strongest features of the module.<\/p>\n\n\n\n
    Users can choose to list only ENC cells that intersect the current QGIS map canvas extent<\/strong>.<\/p>\n\n\n\n
    Workflow:<\/p>\n\n\n\n
    \n
    zoom to your area of interest,<\/li>\n\n\n\n
    activate the extent filter,<\/li>\n\n\n\n
    only relevant ENC cells are listed.<\/li>\n<\/ul>\n\n\n\n
    Technically, this relies on:<\/p>\n\n\n\n
    \n
    NOAA extents stored in EPSG:4326<\/a><\/strong>,<\/li>\n\n\n\n
    automatic reprojection to the current QGIS CRS.<\/li>\n<\/ul>\n\n\n\n

    <\/span>⬇️ Importing a NOAA ENC cell in just a few clicks<\/span><\/h2>\n\n\n\n
    $\"\"$ <\/a><\/figure>\n\n\n\n
    Once a cell is selected:<\/p>\n\n\n\n
    \n
    the ENC file is downloaded from the official NOAA URL;<\/li>\n\n\n\n
    it is validated and processed by the S57Manager S-57 workflow;<\/li>\n\n\n\n
    layers are imported into the configured GeoPackage<\/a> or PostGIS<\/a><\/strong> database;<\/li>\n\n\n\n
    standard S57Manager organization and symbology are automatically applied.<\/li>\n<\/ul>\n\n\n\n
    No manual handling is required.<\/p>\n\n\n\n
    \n\n\n\n
    <\/span>🌍 Multilingual and fully integrated in QGIS<\/span><\/h2>\n\n\n\n
    Like the rest of S57Manager, the NOAA module is:<\/p>\n\n\n\n
    \n
    fully multilingual (FR \/ EN \/ ES \/ PT<\/strong>),<\/li>\n\n\n\n
    compatible with recent QGIS versions (Qt6),<\/li>\n\n\n\n
    fully consistent with other ENC tools in the plugin.<\/li>\n<\/ul>\n\n\n\n
    It is not a standalone tool, but a natural extension of the ENC workflow in QGIS.<\/p>\n\n\n\n
    \n\n\n\n
    <\/span>Conclusion<\/span><\/h2>\n\n\n\n
    With this new NOAA module, S57Manager reaches a new milestone<\/strong>:<\/p>\n\n\n\n
    \n
    direct access to the official ENC catalog,<\/li>\n\n\n\n
