add buffer on tile?

[vincentsarago]

When doing tile based machine learning, you might want to avoid edge effect. One way to work around edge effect is to add a buffer around the tile.

How to

add 👇

        tile_bounds = self.tms.xy_bounds(*Tile(x=tile_x, y=tile_y, z=tile_z))
        if buffer:
            # left, bottom, right, top
            x_res = (tile_bounds[2] - tile_bounds[0]) / tilesize
            y_res = (tile_bounds[3] - tile_bounds[1]) / tilesize
            tile_bounds = (
                tile_bounds[0] - x_res * buffer,
                tile_bounds[1] - y_res * buffer,
                tile_bounds[2] + x_res * buffer,
                tile_bounds[3] + y_res * buffer,
            )
            tilesize += buffer * 2
