I've been working on the Texas Mesonet project, and am trying to get Wind
Barb plots for each of the sites based upon their wind speed and direction.
I've looked through the archives, but the bits of code I've found don't seem
to work when combined together. Below are the important parts of my main
mapfile
SYMBOL
NAME 'circle'
TYPE ELLIPSE
POINTS 1 1 END
FILLED TRUE
END
SYMBOL
NAME 'wind1'
TYPE truetype
FONT 'Esri_Weather'
FILLED true
ANTIALIAS true
CHARACTER "b" # symbol number in character map
end
#
# Working Point Layer
#
LAYER
NAME weather-metar
TYPE POINT
DATA currentWeather
STATUS ON
LABELCACHE OFF
TOLERANCE 10
CLASS
NAME 'Weather Stations'
COLOR 100 200 164
SYMBOL 'circle'
SIZE 7
TEMPLATE "weather_refresh.html"
END
END
#
# Non-working Barb Layer
#
LAYER
NAME weather-barbs
STATUS DEFAULT
TRANSFORM FALSE
TYPE ANNOTATION
DATA currentWeather
CLASS
EXPRESSION "([WINDSPD] = 0)"
SYMBOL 'wind1'
SIZE 25
COLOR 0 0 0
END
END
I realize I'm going to need more classes (with more expressions) to get this
to be a truly correct barb, but I'm trying to take small steps and just get
any symbol to show.
The following layer in my mapfile puts a single barb in the lower left
corner of the map. This shows my fontset is set up correctly (right?).
LAYER
NAME credits
STATUS DEFAULT
TRANSFORM FALSE
TYPE ANNOTATION

POINTS 4 696 END
TEXT 'b'
END
CLASS
LABEL
TYPE TRUETYPE
FONT Esri_weather
SIZE 50
ANTIALIAS true
COLOR 0 0 0

END
END

Hi guys,
I just have a question regarding how Map files work in both CGI and PHP
MapScript environments?
In a CGI environment say I go to my MapServer html pages and fire up the
default page e.g index.html. Is it correct in saying that doing this
request gets sent to mapserv.exe containing, among other things, the
path to a map file e.g demo.map? MapServer now parses the Map file,
loads the data specified and creates an image in the IMAGEPATH directory
which is specified in the map file?
Say I now zoomed in on the map, another request is sent to the
mapserv.exe except this time the minx, miny, maxx, maxy are specified.
Because of its stateless nature does MapServer have to parse the map
file again reloaded all the data and restore any database connections?
Regarding a PHP MapScript environment (which I'm still coming up to
speed with, so please excuse me if I don't use the correct terms) when
the default page is fired up a few lines like the following tell
MapServer to parse the europe.map file and create an image:
$map_path="/var/www/html/ms/map_files/";
$map = ms_newMapObj($map_path."europe.map");
$image=$map->draw();
$image_url=$image->saveWebImage(MS_PNG,1,1,0);
If I now zoom in on the map, is it possible to reuse the $map object
used in the above lines of code, or do I need to recreate the object
again, resulting in the parsing of the map file again and reloading and
restoring of the data connections?
Thanks,
Benjamin Wragg

You need the Live Connect classes, which I think I found on the netscape
site. They are in "winNPSDK.zip" or "winsdk40.zip". I found the Sun Java
1.3 sdk worked better (it produced code that ran under IE)

I never got the MS compiler to work.

If by layer you mean shapefile:
To "add" features to an existing shapefile you need to actually create a new shapefile object and loop through each of the features in the existing shapefile and add them to the new shapefile.
Then before closing the shapefile object you can add new features to it and then overwrite the old shapefile with the new version.
Why?
There is more discussion in the archives regarding that but for the most part the original shapefile design (if I understand correctly) was for quick read access and not write access.
There is a PerlMapscript example towards the top of (look for "Does the shapefile already exist or is it yet to exist."):
http://mapserver.gis.umn.edu/cgi-bin/wiki.pl?PerlMapScriptExamples35ex8
And, yes, we actually use that script to add features to a shapefile.

Hi,
current version of mapscript enables adding object to EXISTING shapefile
(I use it frequently).
The shapefile may be opened like this:

References:
Message-ID: <3DECE498.6020606@frw.uva.nl>
Luke,
The way you do it the Barb layer has to be defined as a POINT layer. You
are symbolizing individual points based on classes and symbols from the
MapFile itself. Alternatively, you can use an ANNOTATION layer, but in
that case the annotation for each site (i.e. the character numbers of
the wind-barb symbols) has to be present as a separate column in the
DATA-file (or computed via PostGIS). In that case you only need a
LABELITEM, and all sites will be labeled according to the accompanying
character. I agree, it is a subtle distinction.

IE 5 has problems printing 8-bit palettized PNGs. The bug was fixed in =
IE 5.5 and is still fixed in IE 6 versions. The PNG you printed =
successfully was probably a 24-bit PNG, which does not trigger the bug.

Subject: [Mapserver-users] PNG file printing from browser
Hello List,
=20
I have a query about printing the map image files generated by =
Mapscript. If I try to print a map as a png image file from an IE5 =
browser it prints out incorrectly - just lots of black. I thought the =
problem might be with the browser unable to print png format but other =
png file I found on the web seem to print ok from my browser. I =
converted the output to JPEG and that prints ok but the file size is up =
to 5 times larger than png and is very slow to download.
=20
Any suggestions gratefully received.
=20
Regards,

Subject: [Mapserver-users] Wind Barbs / Truetype font annotation?
References:
Message-ID: <3DECEE06.5080000@otsys.com>
I had the worst time with creating custom symbols until someone passed
me a link which suggested that I needed to declare them in a symbolset
file. I offer that you should create such a file and reference it in
your mapfile with the SYMBOLSET directive. I believe this is
reletive to the shape path, but am not totally sure.
Good luck. If you get something nice I would love to use it for an
internal project here.
Cordially,
