    Usage

    perform-preprocessorcery /some/folder/file.tif

    Potential Preprocessorcery

    This table lists the various preprocessing steps that a file might undergo. These steps are written in the preprocessors folder, each file representing a distinct preprocessing step. Each preprocessor exposes a criteria function that determines whether or not it should act on the incoming file. The order of this list is the order in which preprocessors would be applied to any single file that matches multiple criteria.

    preprocessor criteria description
    tif-toBytes TIF file with 16-bit pixels Scale 16-bit TIFF files to 8-bit
    tif-reproject TIF file that is not in EPSG:3857 Reproject TIFF file to EPSG:3857
    tif-overviews TIF file Generate overviews for TIFF files
    shp-index Shapefile that has no mapnik index Add a spatial index to shapefile
    geojson-bom GeoJSON string with a BOM char Remove a byte-order-mark from a geojson string
    spatial-index GeoJSON or CSV has no mapnik index Add spatial index (*.index) to GeoJSON or CSV

    Part Splitting

    splitter criteria description
    mbtiles-byTiles mbtiles file 100,000 tiles per part, up to 50 parts max
    serialtiles-byTiles serialtiles file 200,000 tiles per part, up to 50 parts max
