rasterize-vector-tiles converts vector tile sets in .mbtiles SQLite archives to PNG raster tile sets.

## Features

- Reads: Vector tiles (.mbtiles)
  - Reads protobuf .pbf vector tiles
  - Compressed (deflate, gzip) or uncompressed tiles
- Writes: Raster tiles (.mbtiles)
  - Containing .png data
  - Transparency
  - Configurable property to use for color

## Use

rasterize-vector-tiles has command-line options:

```console
$ npx rasterize-vector-tiles
Usage: npx rasterize-vector-tiles <source> <target>

source    Vector tile set in .mbtiles format
target    Raster tile set to be created (.mbtiles)

Options:
   --colorprop value    Feature property to use for gray level (0-255), default='value'
   --nodata    255      Colorprop value to interpret as nodata (will not be rendered), default=255
   --antialias none     Control anti-aliasing (none/default/gray/subpixel), default=none
   --zoomlevel 14       Upper limit on zoom level to rasterize (0-99), default=highest in input file
   --png                Export as individual png files rather than .mbtiles archive
```

## Sample workflow

```sh
# Rasterize the highest zoom level in source
node rasterize-vector-tiles.js src_vtiles.mbtiles dest_png.mbtiles --colorprop value --nodata 255

# Build all lower zoom levels
gdaladdo -r average gradient.3857.mbtiles 2 4 8 16 32 64 128 256 512 1024 2048
```
