Summary: i'm getting an error

Initial Comment:
Hi,
I'm not sure if i'm posting in the right place.
I installed phpweather and it is working with MySQL db.
The only problem is when i get a METAR with no data, i 
receive an error:

Notice: Undefined variable: metar_time 
in /home/wwwfly/public_html/metars/data_retrieval.php 
on line 430

Notice: Undefined variable: metar_time

already sent by (output started

How can i correct this?

Thanks

That's a bit strange --- if it creates one table, then I would expect
to create them all...

The code to create the tables are found in db/pw_db_mysql.php.  Having
the SQL code in an extern file would actually be a good idea, I've
just never thought of that before.

  function create_tables() {
    if (!$this->connect()) {
      return false; // Failure!
    }
    
    /* First we make a table for the METARs */
    $this->query('DROP TABLE IF EXISTS ' . $this->properties['db_metars']);
    $this->query('CREATE TABLE ' . $this->properties['db_metars'] . '(
   icao char(4) NOT NULL,
   time timestamp(14),
   metar varchar(255) NOT NULL,
   timestamp timestamp(14),
   PRIMARY KEY (icao))');

    /* Then we make a table for the TAFs */
    $this->query('DROP TABLE IF EXISTS ' . $this->properties['db_tafs']);
    $this->query('CREATE TABLE ' . $this->properties['db_tafs'] . '(
   icao char(4) NOT NULL,

Re: Generating weather maps

[Phil P. <phi...@sw...>]

Sounds like your Weather Map stuff is progressing along quite nicely.

After having identified how we could do it, I haven't actually *done* 
anything more about putting co-ordinates into pw_stations. (busily 
hacking at the code for other parts of my site, so far)

However, having said that, I will note (probably mentioned this on the 
list before) that I've been playing with AirSort

http://utenti.lycos.it/tingon/airsort/

It comes with a table (named airsort) with the following fields:
     nome (italian for Name)
     IATA
     ICAO
     citta (italian for City)
fields named
     la_? and lo_? (where ? is each of g,p,s,d)
altezza (Italian for height)
lunghezza (Italian for length)

la_d is either N or S
lo_d is either E or W

So it's clear that the la_? and lo_? fields are the latitude and 
longitude stored as seperate Degrees/Minutes/Seconds

It'd be pretty much trivial to write a short script to read ICAO and 
LAT/LONG and inject them into newly created fields on the matching 
pw_stations table. (I can do that)

Also we'd really also want someone to process through the original US 
ICAO stations listing file to ensure we have all the latest listed 
stations and correct co-ordinates. (I can do that, too)

So, basically, getting the data into pw_stations (and verifying it) is 
work, but not difficult (I'd be happy to do it) what we need is someone 
with better PHP skillz than myself and more eperience with hacking at 
phpWeather to take those fields of information in the db and make good 
use of them.

eg mostly importing them into structures when a station is referenced 
from the database.

I've (badly) hacked at a "is it daylight savings time" into the 
pw_images code which works for my locality, with the LAT+LONG data and 
I've written a function which calculates Sunrise and Sunset from 
date+lat+long. So if someone added code for "get lat+long+DST_info from 
the db and inject it into the in-menory structures" to phpWeather, I can 
polish off the rest of the work (ie getting the data into the database, 
and work on pw_?? output routines) to get

- Daylight Savings for all stations
- calculated sunrise/sunset times for all stations
- return correct day/night images based on the above

Re: Generating weather maps

[Jonas K. <me...@j0...>]

Hello,

I updated my approach to generate weather maps for every country with
phpWeather. You can see the current version at
http://www.j0nes.de/wetter/. Currently I included maps for Denmark,
France, Germany and Spain, but other maps can also be integrated.

I found a very useful class named Geoclass at
http://sourceforge.net/projects/geoclassphp/. Geoclass can draw maps
out of .e00 textfiles (which are freely available for almost every
country at http://www.maproom.psu.edu/dcw/) and also does the
transformation from latitude/longitude values to x/y-positions on the
map.

A drawback is that I need several values for every map that you have
to figure out first (try and error), for example the range in
latitude/longitude for this country or the size of the map in pixels
and thus the width-to-height-ratio.

What about the latitude/longitude values for all weather stations?
Phil, browsing the archive I found postings that you had an idea
how to put those values in the pw_stations table. Did you advance in
this?

RE: Request Help With Output From PHPWEATHER

[John C. <jo...@ne...>]

It's pretty easy:

//You need to include the phpWeather class on your site=20
require_once(FUNCTION_PATH . "phpweather-2.1.2/phpweather.php")

//then instantiate a new weather object, $site =3D the ICAO identifier =
you
want to use
$weather =3D new phpweather(array('icao'=3D>$site, 'offset' =3D> '10'));

// now that you have an object, get it's data
$data =3D $weather -> decode_metar();

// now echo it's temp_f
$temp =3D $data['temperature']['temp_f'];

Echo $temp;

That's untested, but it should work.

Request Help With Output From PHPWEATHER

[Philip I. <pi...@be...>]

I do not know PHP and my knowledge of HTML is limited.  I used to =
program in
Fortran and some Assembly Language, but PHP and HTML are not much like
those.

The PHP WEATHER test page worked fine when I installed the PHP WEATHER
package on the server in
http://www.communitybaptistharvestal.com/phpweather.  Thanks to you and
others for creating this complex software package!

I would like to start PHPWEATHER inside the code for my home page so =
that I
can insert only the current temperature on my home page.  I need help =
doing
this.

From file phpweather.txt, temp_f is the current temperature.  I added:

echo temp_f;

before the ending ?> in phpweather.php as below:

.
.
.
function tms_unix2date($tmp_tms) {
  return gmdate("YmdHis",$tmp_tms);
}
echo temp_f;
?>

When I entered
http://www.communitybaptistharvestal.com/phpweather/index.php?icao=3DKHSV=
&lang
uage=3Den in the browser, I got:=20

Well, I understand. Actually, to create paragraph with reasonable
sentences is much more sophisticated and difficult work, than simple
list of key/values. At least in my native Slovak language. :-)

The code is in the attachement. It will certainly not work for you at
the first time. It has to be used rather as an inspiration. It is plugin
for my personal Nepto.SK website, what has currently over 1500 files.
I will not post all of these files.

Of course, some well-known phpWeather files are included. Also some
library files may be required (at least Platon.php). It is part of our
Platon SDG [1] basic PHP framework [2] and can be found in our CVS
repository accesible via CVSweb [3].

Let me know if you need more information or there will be some problems.

What you have in your current weather box is EXACTLY what I was looking
for. I wanted something in "list" form instead of the big old
paragraph output that comes by default.

Do you have the code available so it will look like what is in your
current weather box?

Thank you SOOO much!

The PhpWeather mailinglist found here is the best place, for then your

Why doesn't it work?

Your idea should work, except that the degree symbol (=B0) is coded as
the corresponding HTML entity: &deg; in the output from most
languages, except in the wind direction in the German output, which I
guess is what you're interested in.

The following seems to works with German:

  str_replace(array('&deg;C', '&deg;F', '=BA', '%'),
              array('Grad C', 'Grad F', ' Grad', ' Procent'),
              $text->print_pretty())

but a more robust solution would be to edit the pw_text_de.php file
directly together with the pw_text.php file.  Search for '=BA' and
'&deg;' and I'm sure you'll be able to figure things out.

No, we also need the positions of the upper left corner and the lower
right corner of the map in addition to the lat/long-data for each
station. Perhaps we could create a new table pw_countries (cc, country,
min_lat, max_lat,  min_long, max_long) to store this information.
pw_stations could then be reduced to pw_stations(icao, cc). I don't know
whether phpWeather uses the country field from pw_stations.

I use the PHP/PEAR Cache::Lite module to do my caching, nice and fast 
and pretty functional.

Have the HTML page do the query, and send the data in the URL to the map 
generate script. Caching this is *trivial* with the Cache::Lite module.

	/* near the start of your script */
	require 'Cache/Lite/Output.php';
	$cacheOptions = array(
	    'cacheDir' => "/full/path/to/cache/directory",		//NB cacheDir needs 
g+wx permissions
	);
	$Cache_Lite = new Cache_Lite_Output($cacheOptions);	
		
	/* when you need to cache something */		
	$cacheID = 
substr($_SERVER["REQUEST_URI"],0,strcspn($_SERVER["REQUEST_URI"],'#'));
	$Cache_Lite->setLifeTime(30*60); // cache LifeTime is in Seconds
	$cacheGroup = "weatherMap" ; // :-) just pick a friendly group name
	
	if(! ($Cache_Lite->start($cacheID,$cacheGroup))) {
	
		/* code here to generate page/image when not cached or cache is invalid */
	
		$Cache_Lite->end();
	}

$cacheID is the unique identifier of what you're caching
$cacheGroup is a name to group multiple cacheIDs (eg you can "flush 
ThisGroup from the cache", as opposed to flushing TheWholeCache)

You mean simply Lat/Long for each station? I've been looking in to that, 
(checkout my earlier posts in the archives) we can get the data easily 
(I just need to get my act together and clean it up and thunk it into 
the METAR station table)

Hello,

Yes, this would be really useful. I already use a simple sort of
caching, that is generating the map on the first request and storing
it. Every other request in the next half hour gets the cached version
of the map. Image generation itself is quite fast, getting all METARs
takes a lot of time. So perhaps scheduling the METAR fetch might be
sufficient.

Another problem is that I have to fetch the METARs twice - one time in
the map-generating script, the other time in the HTML-page to display
the onMouseOver-Information for every station. Even with the built-in
caching of phpWeather, I still have to query my database two times.
Has anybody got an Idea how to solve this?

Nice idea. World map generation can also be done with the script I
use. We also need positions for every country, so it would
even be possible to generate the ImageMap to select a country
dynamically.

Re: Generating weather maps

[Phil P. <phi...@sw...>]

Very nice.

A simple workaround for the "it's not fast" issue would be to schedule 
(eg cron) the map generation rather than recalculating it for each Page 
View.

I believe most METARS are only released on an hourly schedule, though I 
think I recall reading somewhere that some locations generate 
half-hourly ones.

One simple thing I'd always thought would look nice was a worldmap with 
every METAR station pinpointed. ImageMap to select a country, then show 
(for example) your country weather map, and image-map to get detailed 
METAR report.

[Jonas K. <me...@j0...>]

Hello there,

as Martin posted some days ago, I developed a little weather map with
the help of phpWeather(see: http://www.j0nes.de/wetter/ - be patient,
a lot of METARs have to be fetched *g* - but weather.noaa.gov seems to
be down, so no data for now).
Together with the idea of having lat/long-data for every station in
the database, it would be possible to generate those maps for every
country on the fly.

I just checked how to figure out the positions on the map with
latitude and longitude, and this works quite well - assuming that we
have the exact location and range of the map.
A problem might be to find suitable map data for each country.

But... I found a nice Sourceforge project called GeoClass. It has some
very nice features such as converting lat/long-positions to
x/y-positions, getting position data from DB and storing them in a
GeoObject or, even better, generating maps out of a .e00-textfile.
You can find this project here: http://sourceforge.net/projects/geoclassphp/
I will have to take a closer look at this project. With the help of
those classes weather map generation might get a lot easier.

Well... I've always tried to attract people to the project in an
attempt to stimulate growth. I can see that I've not spend that much
time on PhpWeather lately --- I wasn't even the guy making the latest
release (Etienne did that, thanks!) so I now try to make it easy for
other people to get involved.

That sound very promissing!  I'm sure we'll find a way of integrating
this functionality.

I do have a login (somewhere, just need to find it again), though I 
would suggest you hold of on adding me to the project just yet.

So far I've been simply looking into the requirements and issues behind 
adding this kind of functionality. I've even done most of the work 
modifying sunrise/sunset calculations into a PHP function (probably 
needs a few 'neatness' type cleanups {eg auto-convert DMS to degrees}, 
but it works).

	function calc_SunriseSunset($date (=timestamp), $timezone (=hours from 
GMT, inc DST),
		$latitude (as decmal), $longitude (as decimal)) {}

	returns an array being sunrise-timestamp, sunset-timestamp

On any page on my website (http://home.swiftdsl.com.au/~Phil.Pierotti/), 
there's a 'widget' showing the weather (icons) for Sydney (Australia) as 
extracted by PHPWeather. If you 'mouseover' the (details) link, a DHTML 
popup (via overLib, see my credits page) in the window will show you the 
full report. The last line in said detail report uses the rise/set times 
as calculated by this function.

The other day I started looking at the PHPWeather code itself 
(spefically, to integrate calc_SunriseSunset into day/night evaluation 
for images) , and my initial (ten second) analysis was along the lines 
of "this will be non-trivial" (mainly due to my lack of familiarity with 
the code , and being relatively new to PHP programming).

Basically, I was hoping there was someone more familiar with the 
PHPWeather code who was interested in running with this now that I've 
gotten some of the basics started.

I spent yesterday playing around with AirSort and integrated it with the 
  PHPWeather driven page on my site (though it's not 'live', currently 
only on my private test server - I could post a small trimmed screenshot 
for the impatient). The biggest hassle I had was that (I think due to 
some CSS thing I'd done) IE wanted to not draw the table properly (for 
the empty cells below the point), so the pinpointing was incorrect. 
Adding in explicit heights for the table cell below the point fixed it.

I've also tweaked it for both 'large'(800x400) and 'small' (400x200) 
maps (and made small maps from the existing large ones). Still need to 
finish a few more minor 'flexibility' type changes, but it works nicely.

 From my basic testing, I suspect some of the co-ordinates are off, and 
several of the ICAOs from PHPWeather don't have entries in the AirSort 
table. Obviously some data-cleanups due here.

So at this point I'm looking to tackle the AirSort flexibility cleanups, 
and data correctness. Once that's done I'll look at more work on the 
PHPWeather Lat/Long&Rise/Set issue (since I'll have clean data to work 
with); however, as I mentioned earlier, it will probably be better (or 
at least faster) handled by someone who is already familiar with the code.

It would be very cool to have this functionality in PHP Weather, I've
asked Jonas for a SF login so that I can add him to the project.
Unfortunately I haven't been that lucky with adding people to the
project lately because of strange SF bugs:

Re: Using PHPWeather question

[Daisyhead <je...@da...>]

I don't think I'm explaining myself very clear on what I want my weather to
look like. I want a simple list, without the whole paragraph text. Something
that look like this:


Temp:
Feels like:
Conditions:
Wind:
Humidity:
Dewpoint:
Pressure:
Visibility:


And this is the code I"m trying to tweak to get the information to be listed
as above:

<?php
require('/home/xxx/public_html/weather/phpweather.php');
$weather = new phpweather();
$weather->set_icao("KOMA");

$foo = $weather->decode_metar();


$temp_c = $foo['temperature']['temp_c'];
$temp_f = $foo['temperature']['temp_f'];
$miles_per_hour = $foo['wind']['miles_per_hour'];
$dew_point = $foo['dew-point']['dew_point'];
$visibility_less_than = $foo['visibility']['visibility_less_than'];
$feelslike = $foo['feelslike']['feelslike'];
$weather = $foo['weather']['weather'];
$rel_humidity = $foo['rel_humidity']['rel_humidity'];
$altimeter = $foo['altimeter']['altimeter'];

echo "Temp: $temp_f &deg; Fahrenheit<br>";
echo "Feels like: $feelslike<br>";
echo "Conditions: $weather<br>";
echo "Wind: $miles_per_hour MPH<br>";
echo "Humidity: $rel_humidity %<br>";
echo "Dewpoint: $dew_point<br>";
echo "Pressure: $altimeter<br>";
echo "Visibility: $visibility_less_than";
?>


Is there any way to list out the output instead of having it in paragraph
format?

Thank you,
Jenni

We've now got our own icons drawn by Justin Heideman --- but
if other people have icons that they would allow us to
redistribute, then please let us know!
We'll work something out so that PHP Weather can start
support theme-packs or something like that.

Sure the icons are copyrighted, but perhaps some of the
sites would allow us to ship them? We would of course give
full credit and add a link back to their site. I think it's
worth to investigate.

Regardless of whether or not we can get images from those
sites, then pw_images needs to be updated. It should support
several different sets of icons --- we already have two sets
of icons in 1.x because of the WAP phones.

In principle good, but all of these images are copyright to
their original owners.
I feel it would be good to include a set of smaller icons
with the program - although we'd have to create them
ourselves...

Must of the stuff there
(http://www.nws.noaa.gov/mdl/icwf/avnfps/editor.html#TAFDe
coder) is already in the cvs code.  What I think remains is :

- time consistency checks
- Consistency Checks Within a Group
- NSW (no significant weather)
- NIL( AMD) (augmented data) ??

When I did the basic decoding I used the regex's in
decode_matar() and I found that only wind shear was missing
(it's not in METARs).  

I think the issue that must be resolved is translating the
various time-periods (FM BECMG TEMPO PROB) into hour-by-hour
information.  Or we could just spew out the time periods
as-is.  Perhaps we want to have a way of getting the
complete forecast for given hour(s)?  The difficulty lies in
the fact that some periods such as BECMG only give some data
such as wind but not visi or clouds...  Such as this example:

CYVR 111438Z 111512 12008KT P6SM SCT010 BKN060 TEMPO 1519
6SM -SHRA SCT008 BKN030 BECMG 1921 25010KT BECMG 0002 29013KT

So we could go through the periods in chronological order
and keep the old values that haven't changed while updating
the values that have changed (except things like descriptive
weather).     Keeping in mind that a TEMPO period is only
temporary and has no effect on subsequent periods.

Does someone have a good link that describes precisely the
meaning of the period types?

  The parts remaining are: pretty output, translation, full

missed.  Please let me know how I can contribute.
