Since two numbers are given and the challenge is about geography
it can be deduced that those numbers represent coordinates.
Latitude und longitude normally are numbers with at least one
decimal place so the bitstrings are single precision floating point values.

[cord.c](cord.c) takes those bitstrings and converts them into human-readable form:

-70.249863 -18.529234


Entering those into [OpenStreetMap](https://www.openstreetmap.org/search?query=-70.249863%20-18.529234#map=6/-70.250/-18.529) unfortunately yielded nothing at first:

But after swapping the coordinates to

-18.529234 -70.249863

you get a [better result](https://www.openstreetmap.org/search?query=-18.529234%2C-70.249863):

The task says that something can be seen from a birds eye view but nothing can be seen yet. You have to zoom in very closely until you can see the following:

It says "Coca-Cola Logo" and the flag is

gigem{CocaCola}
