How can I get Tile Count, Tile X, Tile Y details without specifying zoom Level (or LevelOfDetails)?

Question

This is with reference to Google Tile Map or Bing Maps. Is it possible to get Tile Count, Tile X, Tile Y details without specifying zoom Level (or LevelOfDetails) with any k

Answer 1

If you have a bounding box, you can use this python function for finding zoom level (or similar function in your programming language choice):

def level_dic():
    '''
    http://wiki.openstreetmap.org/wiki/Zoom_levels
    '''
    data = {0: 360.0,
        1: 180.0,
        2: 90.0,
        3: 45.0,
        4: 22.5,
        5: 11.25,
        6: 5.625,
        7: 2.813,
        8: 1.406,
        9: 0.703,
        10: 0.352,
        11: 0.176,
        12: 0.088,
        13: 0.044,
        14: 0.022,
        15: 0.011,
        16: 0.005,
        17: 0.003,
        18: 0.001,
        19: 0.0005}

    return data


def getzoom(self):
    data = level_dic()  # our presets
    a, b, c, d = bbox
    r = 3
    dne = abs(round(float(c) - float(a), r))  # ne: North East point
    mylist = [round(i, r) for i in data.values()] + [dne]
    new = sorted(mylist, reverse=True)
    return new.index(dne)

I used this reference. The rest is simple. You need to use Slippy_map_tilenames.
