CLI

This package ships with a command line tool tmx which provides the following subcommands:

• bounds: Print bounds of given Tile.

• bbox: Print bounding box geometry of given Tile.

• tile: Print Tile covering given point.

• tiles: Print Tiles covering given bounds.

Geometry outputs can either be formatted as WKT or GeoJSON. For example the following command will print a valid GeoJSON representing all tiles for zoom level 1 of the geodetic WMTS grid:

$ tmx -f GeoJSON tiles -- 1 -180 -90 180 90

}

Print WKT representation of tile 4 15 23:

$ tmx bbox 4 15 23
POLYGON ((90 -90, 90 -78.75, 78.75 -78.75, 78.75 -90, 90 -90))

Also, tiles can have buffers around called pixelbuffer:

$ tmx --pixelbuffer 10 bbox 4 15 23
POLYGON ((90.439453125 -90, 90.439453125 -78.310546875, 78.310546875 -78.310546875, 78.310546875 -90, 90.439453125 -90))

Print GeoJSON representation of tile 4 15 23 on a mercator tile pyramid:

$ tmx -output_format GeoJSON -grid mercator bbox 4 15 15
{"type": "Polygon", "coordinates": [[[20037508.342789203, -20037508.3427892], [20037508.342789203, -17532819.799940553], [17532819.799940553, -17532819.799940553], [17532819.799940553, -20037508.3427892], [20037508.342789203, -20037508.3427892]]]}
