Why my latitude and longitude point on basemaps reference seems wrong ?

[sugizo]

zoom value : 12
if lower (e.g. 10) then it will cover another city

Why my latitude and longitude point on basemaps reference seems wrong ?

use latitude and longitude getting from geopy
or
search the latitude and longitude value from google
e.g.
Location : Wonosobo, Batang, Jawa Tengah, Jawa, Indonesia
Longitude : 109.8840032
Latitude : -7.0471052

result
the point is too up north in blender (not expected),
the same lat lon value point is lower south when using in saga gis, green gis to generate 3d mesh (expected)

then modify the latitude value (latitude - math.cos(latitude) )
e.g.
Location : Wonosobo, Batang, Jawa Tengah, Jawa, Indonesia
Longitude : 109.8840032
Latitude - math.cos(latitude) : -7.769235150681784

result not expected
the point is too down south in blender

question
how to properly set the lat lon value ?
