area_to_osm_zoom()

searx.external_urls.area_to_osm_zoom

(

area

)

Convert an area in km² into an OSM zoom. Less reliable if the shape is not round.

logarithm regression using these data:
 * 9596961 -> 4 (China)
 * 3287263 -> 5 (India)
 * 643801 -> 6 (France)
 * 6028 -> 9
 * 1214 -> 10
 * 891 -> 12
 * 12 -> 13

In WolframAlpha:
    >>> log fit {9596961,15},{3287263, 14},{643801,13},{6028,10},{1214,9},{891,7},{12,6}

with 15 = 19-4 (China); 14 = 19-5 (India) and so on

Args:
    area (int,float,str): area in km²

Returns:
    int: OSM zoom or 19 in area is not a number
