Filter coordinates in a given range

I've got hundreds of .out files with geographical positions, that I will bulk import into an SQLite database. However, to save time, I will only import the line with geographical coordinates inside some intervals.

The file is like this:

value;value;longitude;latitude;value;value
value;value;longitude;latitude;value;value

So everything that isn't inside several latitude, and longitude intervals should be deleted from the file.

for f in *.out
do
for each line in $f:
    if not longitude >= longitude1 and longitude <= longitude2 
    or longitude >= longitude3 and longitude <= longitude4 or
    longitude>=longitude5 and longitude<=4:
         delete line

I have included a pseudocode to show some effort, but how would I do this in Bash, awk, python or what ever method is the fastest.

The longitude and latitude is the third and fourth value here. I have 21 latitude intervals, f.ex 69.41 to 70.95 (latitude).

Desired output with latitude interval 69.41 to 70.95:

27;2594800;22,35;70,24;14,50;98,00;1391212800;
31;2598;18,76;69,56;230,20;235,00;1391212800;
34;258500;16,58;69,70;18,20;201,00;1391212800;
27;231711000;22,42;70,27;99,20;99,00;1391212800;

Note that this preferrably should be either written to a new file or overwrite the existing file.

If you just have one interval to check, pass them and compare:

awk -v lat=5 -v min_lat=69.41 -v max_lat=70.95 '
        BEGIN {FS=OFS=";"} 
        {sub(",",".",$lat)} 
        $lat>=min_lat && $lat<=max_lat' file

With lat I indicate the column of the latitude, since it is changing in your edits. Note also the fields have a comma to separate the decimals, so I am replacing them with a dot.

Test

$ awk -v lat=5 -v min_lat=69.41 -v max_lat=70.95 'BEGIN {FS=OFS=";"} {sub(",",".",$lat)} $lat>=min_lat && $lat<=max_lat' file
27;1;2594800;22,35;70.24;14,50;98,00;1391212800;
31;3;2598;18,76;69.56;230,20;235,00;1391212800;
34;3;258500;16,58;69.70;18,20;201,00;1391212800;
27;1;231711000;22,42;70.27;99,20;99,00;1391212800;

If you happen to have many min and max values, pass them as a string and slice them, so that you can check against them being in an array:

awk -v lat=4 -v min="69.41 70.39" -v max="70.95 70.86" '
       BEGIN {FS=OFS=";"; n=split(min,minlat," "); m=split(max,maxlat," ")} 
       {sub(",",".",$lat); 
        for (i=1;i<=n;i++)  {
             if ($lat>=minlat[i] && $lat<=maxlat[i])
               {print; next}
        }
       }' file

This reads the intervals into the array minlat[] and maxlat[] and then compares the latitude with all the pairs (minlat[1], maxlat[1]), (minlat[2], maxlat[2]), .... If one matches, it prints the record and skips to the next one, to prevent printing more than once.

Test

$ awk -v lat=4 -v min="69.41 70.39" -v max="70.95 70.86" 'BEGIN {FS=OFS=";"; n=split(min,minlat," "); m=split(max,maxlat," ")} {sub(",",".",$lat); for (i=1;i<=n;i++) {if ($lat>=minlat[i] && $lat<=maxlat[i]) {print; next}}}' file
