Let’s be honest, Santa outsources deliveries to poor elves working as self-employed contractors, and on top of that they even have to pay for their own sleighs!

What was bound to happen finally did… and one of the elves had a burnout. We know he left Santa’s official office, but he can no longer speak… He only managed to hand over a piece of paper containing this:

246 ➡️ 1919.48
124 ➡️ 659.14
177 ➡️ 983.98

Poor Santa has called on us and on our new tool!

Question

Which major cities (with more than 100,000 inhabitants) was he supposed to deliver to (in order, using the local spelling)?

The instructions provided do not seem very clear… What do these numbers mean? And what is this “new tool” Santa is talking about?

Let’s start by searching the official Santa Claus office location!
By Google search Santa Official Office, the first result is Santa Claus Office. As I trust everything I see online (don’t), I trust this result and open the site to find its location.
The pretty “OPEN EVERY DAY” button leads to the location page, giving the address: Joulumaantie 1, 96930 Rovaniemi, Finlande.

Now, we need to find the “new tool” Santa is talking about.
As each day-question is written by a different author, let’s check today’s author (osint group) “Oscar Zulu” and see if they have any tool.

Let’s search Oscar Zulu on Google to find their website.
On the site (in French), there’s a button called “OSCAR ZULU TOOLBOX” leading to this page listing multiple tools.
We’re mostly searching a tool related to map, as we need to find cities. We maybe need to create a route between cities using the given values?
In the “GEOINT” section, there’s a tool named RhinoMap created by Oscar Zulu (recognizable by the rhino logo, as every of their tools).

From here, we can search “Santa Claus Office” on the searchbar to set the starting point. The result’s location is the one we found earlier in Rovaniemi, Finland.
Now that we have our starting point, let’s use the tool “Measured Line” that allow us to create lines with specific azimuth and distance. In fact, the given values seems to be the azimuth (in °) and distance (in km) constraints to create a path!

Entering the first values:

  • Lock Distance: 1919.48×1000=1919.48 \times 1000 = 1919480m
  • Lock Azimuth: 246°

And then clicking on the starting point, the line is drawn automatically to the first destination.
Repeat the operation with each values, starting from the last point each time, giving 3 ending points.

You can find a map with all lines drawn here: Full map

Answer

Edinburgh Amsterdam Aix-en-Provence

Alternative

Using a tool was not mandatory. Is was indeed possible to do it “by hand” with any map app, and calculate the distances and angles!
