[OSGeo-Discuss] Is there an Open Source softwareapplicationthatwill draw a graticule on a map?

[Brent Fraser]

Landon,

  It's an interesting problem.  From my perspective, a map
without a graticule, scale bar, and projection statement
(with parameter values!) is just a diagram (kind of like a
tiff without geotiff tags or shapefile without a .prj file).
It can be useful, but don't try to integrate any spatial
data or measure any coordinates.

    A graticule straddles the spatial (GIS/drawing programs)
and graphic (page layout) domains.  Traditionally (on paper
topographic maps) the graticule labels have been shown
outside the mapped area and most GIS applications can't
handle this unless they implement some kind of page layout
functionality.   And forget about the generic page layout
programs placing a graticule as they have no world
coordinate system functionality (without a plugin).

    So perhaps your solution is the answer: create open
source mappping plugins for the page layout projects you've
listed (and stop expecting GIS programs to layout and print
a map).  I'll have to look into that...

    And for you MapServer implementers, a homework
assignment: create margins on your map with inline polygons
to blank out the map data and emphasize your GRID labels
(see attached map, er I mean diagram).

Thanks!

I've given this issue a lot of thought. It seems to me that
"cartographic" map production really involves two (2)
separate
functions:

[1] The ability to draw graphics and annotations.
[2] The ability to layout graphical elements on a page or
sheet.

I think it is easy to underestimate the complexity of these
two (2)
functions. A GIS program will be a lot simpler and easier to
maintain if
it doesn't tackle these two (2) functions at all, but
instead focuses on
the management of spatial data. Really the display of this
spatial data
on a computer screen is just part of the user interface that
helps the
user manage the data.

I think it is a lot smarter to leave the drawing to the
drawing programs
and the page layout to the page layout programs.

For example, there is some limited support for printing and
page layout
in OpenJUMP via plug-ins, but it isn't anything terribly
sophisticated.

I think the best solution for the open source geospatial
community is to
export spatial data from our programs in an open format for
graphics
like SVG, and then enhance those graphics in an open source
drawing
program like Inkscape and layout map sheets in an open
source desktop
publishing application like Scribus.

Imagine what we could accomplish as a community if we all
used Inkscape
and Scribus for cartographic map production instead of
designing our own
map production functionality. Imagine what could be
accomplished if we
took that time we would invest in implementing the drawing
and page
layout functionality that already existed in some
high-quality
applications and invested it instead in the other functions
of our
applications, or even better, in the drawing and page layout
applications that we would use as replacements.

I've contacted the Inkscape development team to ask about
contributing.
I have plans on helping out with the lib2geom library that
will be
integrated into Inkscape, although it means I need to learn
C++, which
gives me a serious headache. I haven't had time to get
involved like I
would want, but it is still an eventual goal of mine.

I really encourage the open source geospatial community to
take close
look at Scribus and Inkscape as options for cartographic map
production.
OpenJUMP can export SVG, and some of our users have made
beautiful maps
with the two programs. I really don't think there is much
you couldn't
do in the realm of 2D maps with the two programs. There is
even the
potential here to share standard map sheet templates for
Scribus and SVG
graphics for things like north arrows and scale bars for
Inkscape.

Puneet,

  I'm hoping that (someday?) high quality cartography WILL
be point-and-click.  The three apps I looked at come pretty
close:
    uDig    - sophisticated, complicated GUI; focus on GIS
not cartography
    QGIS    - simple GUI, a print composer, but features
(e.g. a real graticule) missing
    gvSIG   - look and feel of ArcView 3.x (the good and the
bad), but no graticule


  I think Paul Ramsey said it best in the Directions Mag
interview
(http://www.directionsmag.com/article.php?article_id=2517&tr
v=1):

"The first project to produce a stable and complete ArcView
3 replacement will gobble up a huge user share, and become
the default application for building the "high end" analysis
and cartography functionality."
