As usual in such competitions, at first you need to convert the geotiff pixels to latitude / longitude.

I remember successfully doing so with code like this:

```
def polygon_to_tuples(polygon):
x, y = polygon.exterior.coords.xy
x = list(x)
y = list(y)
return list(zip(x, y))
def coordinates_to_pixels(x, y, transform):
"""
The Affine object is a named tuple with elements a, b, c, d, e, f
corresponding to the elements in the matrix equation below,
in which a pixelâ€™s image coordinates are x, y and its world coordinates are x', y'.:
| x' | | a b c | | x |
| y' | = | d e f | | y |
| 1 | | 0 0 1 | | 1 |
"""
rev = ~transform
return rev * (x, y)
polygon = df.loc[100].geometry
tuples = polygon_to_tuples(polygon)
pixels = [coordinates_to_pixels(tup[0], tup[1], transform) for tup in tuples]
```

The coordinates of individual polygons seem to be more or less in line with house coordinates on Google Maps, but when I try to convert them to geo-tiff pixels, I get strange values.

Has anyone faced this issue?

I also tried using `geoio`

with similar results.
