What’s behind that Graph - Misc

we detected a messages sent to Elliot friend containing a text and a picture
text: Hello Elliot see the gangsters are following me, all my phone calls messages, voice mails are watched… i know you need that flag but i can’t send it directly, see i have a way…. ill send you this image then …. oh noooo nooooo i am detected bye bye ….
Note: if the flag have spaces discard them, example: if the flag was semo jo the flag will be semojo
flag format: BAU{flag}

first thing that comes to mind while seeing this picture ( a graph with points ) is the coordinates for a location as latitude and longitude
let’s reveille the secret behind this graph

x = value is ascending in order like 1,2,3,4… for every point
y = values are changeable without any order → so here we are going to take y values
from the graph we see that there is 2 separate parts one above the x-axis as positive and one under the x-axis as negative so we will assume that the latitude is positive and longitude is negative because the order is always as latitude and longitude respectively for any given location coordinates
counting the numbers we see that latitude first part have 9 digits and longitude the second part have 10 digits
also we have some points that have labels and that’s so important for the coordinates because we don’t know after how many digits we will put the dot but from this picture we will assume that the latitude will have 2 digits than the dot as XX.XXXXXXX and the latitude as 3 digits than the dot XXX.XXXXXXX
if we look closer after each dot in the latitude and longitude there will be 7 digits and that’s what we saw in point d

combining what we analyze from the upper point we will have the following coordinates for a location as latitude and longitude ( 34.1185107,-118.3011183 )
going to google map and search for that location ( 34.1185107,-118.3011183 ) we have the following location
