Perhaps your data was corrupted.  Perhaps you should debug your code
before posting flames.  I used this program to view the data:


	main()
	{
		float	x1,y1,x2,y2 ;
		int	iret ;

		openpl() ;
		erase() ;
		space(-1800,0,-600,900) ;

		while( (iret = scanf("%f %f %f %f",&x1,&y1,&x2,&y2)) == 4 )
		  line((int)(x1*10), (int)(y1*10), (int)(x2*10), (int)(y2*10)) ;

		closepl() ;

		printf("iret = %d\n",iret) ;
	}

And was quite happy with the results.  This program is linked to the
unix plot library by the way; it's standard on suns, and probably most
other unix systems too.  It took me less time to write and debug this
than it probably took you to post your flame.

I almost believed this, but thought I'd try it for myself anyway.  Good
thing too.


For those who are interested, I'm including a short shell archive containing
the program above and two programs to pack and the files into a more
compact form.  If you follow these steps:

	% bpack < ar1 > d1
	% compress d1
	% uuencode d1.Z d1.Z > d1.uu

you reduce the space to about half and get something that can still
be sent out to the net.  Follow these steps at the other end to unpack:

	% touch d1.Z
	% chmod a+w d1.Z
	% uudecode < d1.uu
	% uncompress d1
	% bunpack < d1 > ar1


Perhaps Mr. Peterson could be persuaded to post the rest of the map
in a compressed form one section per week?  I'd really appreciate seeing
the rest of this data.

Also, does anybody have political boundaries?
