Perl Scripts

[Guest]

Hi,

I installed Perl (build 616) on my PC (win98), for the first time ever, and tried to run the Perl scripts.

The terrain feature scripts (procppp.pl and procae.pl) work fine, no problems, but I couldn't make the DEM script (dem2lf.pl) to work.

The script is looking for for a file, MD5.pm (some RSA thing?), and can't work without it.
Since the perl install was really clean and without any suspicious history of older perl versions - I can only assume that this is an optional component that can be downloaded somewhere. Any ideas where?

(and once again linux users have another built-in advantage...)

In the mean-time, could anyone please help me with the DEM conversion, and create the TerrainView files for me?

The coordinates are:
left_map_x - 30.2
right_map_x - 40.2
upper_map_y - 35.8
lower_map_y - 25.8

Yep it's Israel, close to Death-119's, but not quite - all of Cyprus is included, but without any loose ends from Turkey, and I cut a tiny bit from the west (east of Alexandria) in favor of more airspace around the Iraqi H-3).

Anyway, I'm doing this as a pastime on my spare time. Any help with the DEM is welcome, Thanks.

Hi Daab,

First, make sure you are connected to the internet, dialup, etc.

In your perl\bin directory, type "ppm" and hit enter. The command prompt will look like:

PPM>

Now type "install md5" and hit enter.

The program will connect to the perl site, download the package, and install it (all in about 5 seconds with a cable modem). Self installing software is a nice switch!

Hope this helps.

Doogman,i had tried some time earlier what you said but the L2 file did not appear correctly on Terrianview.Any thoughts?

You may have a perl script dem2lf.pl that is not working properly. According to Julian (and first hand experience) the routine in the script that detects if your on an intel or motorola is not working up to par as of yet. You have to manually edit the dem2lf.pl script to tell it that you are using intel. This is only the case if you are using a windows based platform I believe. Anyway here is what Julian said on egroups about it:

basically its in the getaltitude routine. It should unpack an 's' on
the PC - it does unpack("s", pack("n", unpack("v")) to byte swap on unix.

so the getaltitude routine should be:

sub getaltitude {
my($alt);
$alt = unpack("s", $_[0]);
$alt *= 3.280840; # convert metres to feet
return $alt;
}

I hope that is what you were looking for.

What does it look like, can you give us screenshot?
(load up terrainview, hit print screen key and paste to some paint-program).

Did the L2 file work ok that I sent you?
