wcst_import - option import_overviews_only to import only overviews without importing to the base coverage

[Bang Pham Huu]

The usecase is for Sentinel 2 with nested overviews inside JPEG2000 files. Once has imported files to base coverage (S2) and now wants to import only the overviews, e.g. levels: [0, 1] to overview coverages (S2_0 and S2_1).

This needs an option in the ingredients file for wcst_import.

• syntax: in the recipe options section import_overviews_only
  • if true: import all overviews contained in input file, but not the primary image contents
  • if false: import primary image contents as well as all overviews in input file (default)

• Example:

"options": {
    "import_overviews_only": true; // import all overviews found, do not touch base coverage
}
