ps.map questions

  Now that I've carefully read the man page for ps.map, I see that it will
do most -- if not all -- that we require. I didn't see a few things, though,
and I'd like some insight into how to do these things.

  1) Where can I specify the paper size for the map? For example, my HP
DeskJet 2500C can handle (US) sizes A and B; actually, up to 13" x 19". I
didn't see a "size" option.

  2) What do folks do for a north arrow? If someone has a collection, is it
available to the rest of us?

  3) If I read the man page correctly, I can pre-defile such things as the
title block, neat line and north arrow, and have them included in the ps.map
instruction file each time. Of course, I need to prepare four copies: two
paper sizes at each of two orientations (portrait and landscape).

  I'm sure that I'll come up with more questions as I dig into using this
module, but these floated up right away.

Thanks,

Rich

Hi Rich,

please read additional ps.map.new.html:
http://www.geog.uni-hannover.de/grass/gdp/html_grass5/html/ps.map.new.html
(added just now).

Radim Blazek <Radim.Blazek@dhv.cz> added new features:
- cwidth > plotted line width = cwidth * category
                           
   ( usefull for any continuous quantity parameter such
                            as flow in rivers)
                           
- offset > plots parallel line in offset distance
                           
- coffset > offset distance = coffset * category
                           
                    ( combination of cwidth + coffset makes available
                      display parameters
                       in each direction such as traffic on roads)
                           
- lpos - position in legend (0-omit, repeated number - merge more
                           vectors in one row)
These options are not implemented in interactive mode yet.

acolor r g b - for plotting vector areas and
label label for map - for legend labels of vectors

Regards,

Markus

Papers are defined in $GISBASE/etc/paint/psdevices as 'devices' and selected by ps.select

You can create any picture in .ps format and use 'psfile' option to include to output.
( I would like add option 'epsfile' which could specify also also position,
scale and rotation sometimes)

Is old. Up to date html man is attached and man should be under CVS
(could Markus Neteler replace it on Web by new one)

........

label label for map - for legend labels of vectors

And:
'ref' for vector line ( justification, fill appendixes of line) and
'labels' reads ROTATE: from paint/labels/file.
+ probably twice as many bugs =>

Suggestion:
- remove p.map
- remove ps.map.old
Rename p.map.new to p.map
Rename ps.map.new to ps.map

ps.map.new is not tested enough now and we should add more options. Therefore
I think that it is not time to replace ps.map.old (ps.map) by ps.map.new.
It could cause problems. I expect ps.map.new to be module with more options
but buggy for few months.

Request for help:
offset, coffset and ref are marked as experimental in man because I could not find
any free function for creating PARALLEL LINE in distance and I do not know how to write it
better than it is now. Do anybody know about such function freely available.
