The following datasets gather the respective outputs of the intermediate
stages of the computations of the  cityGMLto3DTiles data pipeline, pipeline
that transforms CityGML datasets (usually originating at the Open Data site
of the Metropole of Lyon) into 3DTiles tilesets. The resulting 3dTiles tilesets
(that is the output of the final stage of the pipeline) are gathered in the
   https://datasets.liris.cnrs.fr/3dtiles-tilesets-metropolis-lyon-version1
dataset repository.

Here is a brief description of the respective stages content:
 * stage_0: the orginal data as downloaded from https://data.grandlyon.com/
            We keep a version here, because the original data is sometimes
            altered/changed/modified (without a tagging process or a warning)
 * stage_1: the corresponding unzipped content (generally for the so-called
            BATI content), with corrective patches applied
 * stage_2: the corresponding "splitted" files
 * stage_3: the corresponding "stripped" files
 * stage_4: ?
