Package: libgeography-nationalgrid-perl
Version: 1.6-8
X-debbugs-cc: le...@leeym.com
Many of the man pages say
SYNOPSIS
You should create the object using the Geography::NationalGrid
factory class, but you still need to know the object interface,
given below.
Nobody knows what that means. Please provide examples that work on their
own. Geography experts are not necessarily perl experts.
Here I have managed to made an example from the man pages work on its
own, by adding the two "use" lines:
$ cat ff
use Geography::NationalGrid;
use Geography::NationalGrid::TW;
# default TWD97
my $point1 = new Geography::NationalGrid::TW(
'Easting' => 302721.36,
'Northing' => 2768851.3995,
);
printf("Point 1 is %f X and %f Y\n", $point1->easting,
$point1->northing);
printf("Point 1 is %f N and %f E\n", $point1->latitude,
$point1->longitude);
# transform to TWD67
$point1->transform('TWD67');
$ perl ff
Point 1 is 302721.000000 X and 2768851.000000 Y
Point 1 is 25.026834 N and 121.522413 E
Works great, until we add -w:
perl -w ff

Please fix the program and man pages for all the countries. I get errors
for other countries too.
Also regarding the TW man page,
# default TWD97
Say if you mean input or output.
Also don't you say "Default is 'TWD67'" below?
my $point1 = new Geography::NationalGrid::TW(
'Easting' => 302721.36,
'Northing' => 2768851.3995,
);
printf("Point 1 is %f X and %f Y\n", $point1->easting,
$point1->northing);
printf("Point 1 is %f N and %f E\n", $point1->latitude,
$point1->longitude);
# transform to TWD67
$point1->transform('TWD67');
DESCRIPTION
Once created, the object allows you to retrieve information about the
point that the object represents. For
example you can create an object using easting / northing and the
retrieve the latitude / longitude.
OPTIONS
These are the options accepted in the constructor. You MUST provide
either Latitude and Longitude, or Easting and
Northing.
Projection
Default is 'TWD67', the "TAIWAN DATUM 97". Other projections
recognized are 'TWD67', 'TWD97', but only
'TWD97' is tested.
"the "TAIWAN DATUM 97": don't you mean "the "TAIWAN DATUM 67"?
Other projections recognized are 'TWD67': but didn't you already mention it, so
how is it "Other"?
but only 'TWD97' is tested: The default is not tested, only the "other"
is tested?
Please answer/correct the above on the man page, not just for me.
P.S., Lee, please mention your address le...@leeym.com on the man page.
P.S., Lee, why not round, instead of truncate?
easting
How many metres east of the origin the point is. The precision of
this value depends on how it was derived,
but is truncated to an integer number of metres.
northing
How many metres north of the origin the point is. The precision of
this value depends on how it was derived,
but is truncated to an integer number of metres.
in fact, why not just not "hurt" it at all. That way the example,
Point 1 is 302721.000000 X and 2768851.000000 Y
would not have the 00000s, but instead the original input. Just like you
don't "hurt" long/lat. Yes, after transforming it is inaccurate, but no
need to make things worse --- even before transforming too.
P.S., TW man page:
