LX289 arriving from FAJS obviously was to early to land on rwy 34 in LSZH and was sent into an exceptionally wide holding pattern.
Treasuring the subject

To treasure the subject and issues that Aaron Swartz was fighting for, I would like to refer and remind to my mail to Richard Stallman, Lawrence Lessig and Cory Doctorow, which I wrote on 21st of January 2012.

awk’ing lat/lon
January 10th, 2013
No comments
Here’s how one can convert latitude/longitude values from degrees to decimal format using GNU awk.
# description: convert dec values to lat/lon
# license: GPL 3.0
# input: "N010.00.21.698 E094.24.35.999"
# output: "10.006027 94.41
awk '{
lat=$1;lon=$2;
split (lat, latitude, ".");
latpre=substr(latitude[1],1,1);
latdeg=substr(latitude[1],2);
latmin=latitude[2];
latsec=latitude[3];
latmil=latitude[4];
latdec=latdeg+(latmin/60)+(latsec/3600)+(latmil/3600000);
if (latpre == "S"){
latdec=latdec*-1;
}
split (lon, longitude, ".");
lonpre=substr(longitude[1],1,1);
londeg=substr(longitude[1],2);
lonmin=longitude[2];
lonsec=longitude[3];
lonmil=longitude[4];
londec=londeg+(lonmin/60)+(lonsec/3600)+(lonmil/3600000);
if (lonpre == "W"){
londec=londec*-1;
}
printf "%.7f %.7f\n", latdec, londec;
}'
usage:
echo "N010.00.21.698 E094.24.35.999" | ./awk_converter.sh
output:
10,0060272 94,4099997
