Parameters

min_zoom: integer · default 0 · Minimum zoom level
max_zoom: integer · default 14 · Maximum zoom level
encoding: enum · default auto · Tile encoding: - auto: detect from input (DEM -> terrarium, imagery -> rgb) - terrarium: RGB encoding for elevation data - rgb: standard RGB imagery - rgba: RGBA imagery with alpha
format: enum · default webp · Output tile image format
resampling: enum · default bilinear · Resampling method for tile generation
tile_size: integer · default 512 · Tile size in pixels
precision_by_zoom: boolean · default true · For terrarium encoding, apply zoom-dependent precision rounding to improve compression (mapterhorn optimization)
