CLOUD BASE GRAPHIC - RELEASE V2.1
DESCRIPTION:
This script outputs a 100x200 graphic of the current cloud conditions as a raw jpg image stream.[url=http://www.bashewa.com]
[/url]
o There are 11 cloud type overlays and 34 day and night backgrounds to choose from.
o The windsock has 5 positions.
o There are 28 moon phases each for North and South.
o A future enhancement would be to place the moon according to it’s height in the sky and don’t show it if it’s not visible.
o The script is multilingual.
o Can fetch a METAR from NOAA for cloud conditions at night and/or day.
I plan to use the same script at a later stage to make dynamic icons for the ajax dashboard.
REQUIREMENTS:
This script requires one of the following data files: o Weather Display (WD) .............. clientraw.txt & clientrawextra.txt o Virtual Weather Station (VWS) ..... wflash.txt & wflash2.txt o Heavy Weather (WUHU) .............. currdat.lst
If you intend using it with any other language you also need the translations in your
“language-??.txt” file. See the notes at the end of the script for the required words.
Language translations requires the “common.php” script.
The following settings in “Settings.php” are used but not required. $SITE['wxSoftware'] = 'WD'; // [ WD | VWS | WU ] $SITE['clientrawfile'] = './clientraw.txt'; $SITE['clientrawextrafile']= './clientrawextra.txt'; $SITE['wflashdir'] = './wflash/Data/'; $SITE['metarICAO'] = 'FAJS'; // 4 letter ICAO code for METAR $SITE['WXtags'] = './testtags.php';
GRAPHIC IMAGES REQUIRED:(included) "./images/cb/" ........ background, cloud, windsock & scale images. "./images/cb/moon/" ... moon images southern & northern hemisphere.
USAGE:
Metric :
English: OPTIONAL PARAMETERS: uom= [ M | E] ....................... set units-of-measure (M)etric or (E)glish all= [ 0 | 1 ] ...................... 1=show all elements on picture wind= [ kts | mph | kph | km/h ] ..... set uom for wind alti= [ ft | m ] ..................... set uom for cloud altitude rain= [ mm | in ] .................... set uom for rain baro= [ hPa | kPa | inHg ] ............ set uom for barometer temp= [ C | F ] ...................... set uom for temperature humi= [ 0 | 1 ] ...................... 1=show humidity cond= [ 0 | 1 ] ...................... 1=show conditions cloud=[ 0 | 1 ] ...................... 1=always show clouds when sunny or clear. metar=[ <code> | empty ] ............. get NOAA METAR for given code. Disable if empty. data= [ en | de ] .................... language of data files ie. clientraw.txt lang= [ en | de | fi | nn | sv | es ] . language to use for translation test= [ 1..5 ] ........................ use preset conditions for drawing picture html= [ 0 | 1 ] ....................... 1=output html code for testing, 0=save picture only [color=red][i]PS: passing any of the above parameters will always override the internal settings.[/i][/color]
FOR TESTING USE THE FOLLOWING: http//www.mysite.com/cloud-base.php?uom=M&html=1 ... for current conditions http//www.mysite.com/cloud-base.php?uom=M&html=1&test=1 ... where test=[1 to 5]
AJAX DASHBOARD ADDITIONS
Add the following to your “ajaxWDwx.js” file into the “ajaxLoader()” function
for updateing your cloud height on your Ajax Dashboard dynamically.
Do not include the “<?php" and "?>” when copying (it’s only there for the rendering).
<?php
//--- begin cloud height graphic -----------------------------------------------
stationAlt = 0; // your station altitude in meters if you want ASL (meters = ft / 3.2808399)
temp = clientraw[ 4];
dewp = clientraw[72];
pres = convertBaro(clientraw[6]);
wind = convertWind(clientraw[1]); // gust = clientraw[2]
wdir = windDirLang(clientraw[3]);
rain = convertRain(clientraw[7]);
cloudheight = Math.max(0,(temp-dewp)/0.00802)*1.0 + stationAlt; // in meters
altitude = (useunits=="E") ? Math.round(cloudheight*3.2808399) : Math.round(cloudheight);
above = (stationAlt>0)? ' ASL' : ' AGL';
cloudText = altitude.toString() + uomHeight + above;
param = '?uom=' + useUOM + '&buster=' + altitude + pres + beaufortnum + rain;
set_ajax_obs("ajaxcloudheightimg"
,'<img src="cloud-base.php' + param
+ '" alt="' + cloudText
+ '" title="' + cloudText
+ '" width="100" height="200" hspace="0" vspace="0" align="" border="0" style="" />');
//--- end cloud height graphic -------------------------------------------------
?>
The ajax tag to use for your dashboard is “ajaxcloudheightimg”.
In your “ajaxdashboard.php” script you should tag the cloud height graphic as follows:
<?php
<span class="ajax" id="ajaxcloudheightimg">
<img src="cloud-base.php?alt=<?php echo $cloudheightmeters; ?>m" alt="" height="200" width="100" />
</span>
?>
I DON’T SEE MY CLOUD HEIGHT GRAPHIC:
Have a look wheter you can see the graphic when you look at: [color=blue]http://www.mysite.com/cloud-base.php?html=1[/color]
If you have script errors they will show up here … make the nessary corrections and try again.
Have a look wheter you see garbage when you look at: [color=blue]http://www.mysite.com/cloud-base.php[/color]:
If you see garbage make sure you don’t have spaces before the opening <?php[/b][/color] tag and
the after the closing [color=red][b]?> tag in the following files:`
- Settings.php
- testtags.php … testtags.txt on your computer
-
common.php`
The spaces and carriage returns affect the output of the graphic … remove them.
