[mapserver-users] make labels fit in a polygon

2013-08-29 Thread Mark Volz 
Hello,

A year and a half ago I inquired about how to deal with labeling complex 
polygons.  The basic issue is that the center of the bbox does not always fall 
within the boundary of complex polygons.  At the time one of the developers 
mentioned that using the bbox is much faster than trying to fit a label inside 
of the polygon.  At the time I let the issue go, however I have been hearing 
more users complain about labels not fitting correctly on some of the labels.  
Therefore I am wondering if this topic can be discussed again.

Within MapServer:
I agree that using the bbox for label points is much faster to compute than 
using the actual polygon geometry.  I wonder however if it would be possible to 
add a keyword to allow either the bbox or polygon boundary to determine the 
label position.  This way users could have a choice between speed or precision 
for label placement.

Outside of Mapserver:
Does anyone know of a script that could be used to pre-calculate label 
positions?

Thanks

Yes, the call to msOWSPrintURLType() in msWCSGetCapabilities_Service in 
mapwcs.c pass tag_name == NULL, hence the (null) in the warning. Looking at 
the conditions that trigger the warning, I believe the reason for the warning 
is that you need to define the "ows_metadatalink_href" metadata item.

Thanks David,

Using the correct units seems to have fixed the problem. 

@Jeff : Thanks for pointer, now that I have re-read it all makes sense

Cheers

You might also want to review the "Important Notes" section of the

Re: [mapserver-users] Projections and raster files

2013-08-29 Thread Fawcett, David (MNIT) 
David,

Take a look at the map extent and units.  They should be the units used by your 
output spatial reference system.

In your current map file, you have DD for the units, for 3857, they should be 
meters.  You will also want to express your extent in 3857 coords.

David.

Hello,

I have a number of geotiffs which are currently using epsg:4326 and I would 
like to output a region using epsg:3857.

I am new to mapserver but from what I have read the way achieve this is by 
setting the projection of the map to epsg:3857 and the layer to epsg:4326.

When I set the projections to the same value I get the output I expect without 
a problem, if I set the projections to different values I do not get an error 
but the output is blank.

To make life more complicated I am using mapscript via the Java swig interface, 
the version of mapserver I am using is mapserver 6.1.2.1 which I built from 
source.

If anybody has any advice I would be most grateful.

Re: [mapserver-users] Orientation of vector symbols on a LINE

Thanks Havard, for the pointer to the answer and explanation of the ratio
between SIZE and GAP. I feel like I will use that a lot.

Thanks Thomas for your clarification - my misunderstanding was regarding
the negative values, I hadn't fully  internalized that y=0 was the top of
the symbol.

Re: [mapserver-users] Orientation of vector symbols on a LINE

2013-08-29 Thread thomas bonfort 
Given that there's alot of undefined behavior with vector symbols, the
documentation for anchorpoint is pretty clear about what is supported:

ANCHORPOINT can be used with SYMBOLs of TYPE ellipse, pixmap, svg,
truetype and vector. To ensure proper behaviour for vector symbols,
the left and top edges of the bounding box of the symbol should be at
0.

As a rule of thumb, VECTOR symbols are expected to work correctly if
they respect that rule, i.e. your vector POINTS should have at least
one point with x=0, at least one point with y=0, and no negative x's
or y's.

Re: [mapserver-users] overlaysymbol depreciated?

2013-08-29 Thread Havard Tveite 

Both SYMBOL 0 + SIZE 1 and WIDTH 1 should work, but why don't
you want to use WIDTH?
WIDTH is now the recommended way of specifying the width of
lines.  It is also used in
http://mapserver.org/mapfile/symbology/construction.html

It still draw's correctly, so I'd say its still in the code (I'm running 6.2.1).

Reading: http://mapserver.org/mapfile/symbology/construction.html

it looks like I want have multiple SYLE's listed.  Something like:

CLASS
 NAME 'Railroad'
 STYLE
 SYMBOL 0
 COLOR 0 0 0
 SIZE 1
 END
 STYLE
 SYMBOL 'railway'
 COLOR 0 0 0
 SIZE 7
 GAP -25

Yes?

Which works.  But OverlaySymbol and friends don't seem to be documented.
Did they go away at some point?  What should I be using instead?

Re: [mapserver-users] Orientation of vector symbols on a LINE

2013-08-29 Thread Havard Tveite 

The implementation of GAP has been fixed (center to center
distance between symbols), and so has the calculation of
symbol height.
I guess that the following should work:

STYLE
  SYMBOL "wavy_line"
  WIDTH 1
  SIZE 2
  GAP -6
  COLOR 0 0 0
END

Since you have y values from -1 to 1, and x values between 0
and 6, the ratio between the height of your symbol and the
length is 2 / 6.  The ratio between size and gap should be the
same to make the the line continuous.

Hello, I'm trying to understand symbol orientation and (maybe) use of

The vector symbol that I have been using for line cartography in MapServer

SYMBOL
   NAME "wavy_line"
   TYPE vector
   POINTS

 2 1
 3 0
 4 -1
 5 -1
 6 0

Relevant Style bloc from Mapserver 6.0.3:

STYLE
  SYMBOL "wavy_line"
  WIDTH 1
  SIZE 2
  GAP -1
  COLOR 0 0 0

This did not translate directly to Mapserver 6.2.1, but I came close with this:

STYLE
 SYMBOL "wavy_line"
  WIDTH 1
  SIZE 4
  GAP 6
  COLOR 0 0 0
END

which produced this:
https://dl.dropboxusercontent.com/u/42845001/mapserver6.2.1.png

Obviously I am missing something about how to get the symbol to orient along 
the line, I played with ANCHORPOINT as that  was new in 6.2 and it seemed like 
the default of 0.5 0.5  should work for my symbol, but I also tried several 
other value combinations and it seemed to merely shift the symbol around 
laterally, while maintaining an upright orientation.

So I'm a bit confused on how to achieve the original effect, (behavior 
something like the equivalent of FOLLOW for Labels). Any pointers appreciated...
