Mapping the Disease Trends
West Nile Virus (WNV) is the most widespread arbovirus (viruses that are transmitted by arthropods) in theworld. . During the period of 1996 -1999, the WNV became prevalent insouthern Romania, the Volga delta in southern Russia, and the northeastern United States. The spread of WNV covered the United States from coast to coast in four years, and by then it had 7 infected about one million Americans, killing about eight hundred.Here I mapped the spatial trends of WNV virus in the United States of America.

Add and Remove DOM Elements..
Snippets for adding DOM elements dynamically to the defined DOM element.
Here, "mydiv2" is added dynamically as "mydiv"1's child.
//Dynamically generate Div
var newdiv = document.createElement('div');
var divIdName ='mydiv2';
newdiv.setAttribute('id',divIdName);
newdiv.style.width = "565px";
newdiv.style.height = "480px";
newdiv.style.left = "0px";
newdiv.style.top = "0px";
newdiv.style.position = "absolute";
newdiv.style.border = "1px solid #000";
document.getElementById('mydiv1').appendChild(newdiv);
A good example by Dustin Diaz to remove DOM elements Dynamically.

A thought in the lazy day
Being a geographer, I am so thrilled in my life. I got opportunities to feel nature from the bottom of my heart. I am also an engineer. I found geography is more interesting than engineering; however I love math, statistics, and scientific computing. I never afraid from math meantime, implementing math in geography is very fascinating job for me.
It’s a time to integrate technology with nature so don’t get late to be a geographer and experience ecstatic in your entire life.

How to get Color Brewer Ramp in ArcMap 10?
There are two ways to achieve this:
Method A steps:
1. Download Color Brewer Color Ramp Style Set from http://arcscripts.esri.com/details.asp?dbid=14403
2. Unzip it.
3. Open the Layer properties and click on ‘Symbology’ tab in ‘ArcMap 10’.
4. Double click on one of the color symbol beneath ‘Symbol’ that gives you a ‘Symbol Selector’ window.
5. Click “Style References..”
6. Click “Add Style to List..” and add ‘ColorBrewer.style’ that is obtained from setp 2.
7. If you made it correctly it should be listed in the ‘Style References’.
8. Select ‘ColorBrewer.style’ and make it default.
9. Close the layer properties once and open it again, you will see newly generated color ramp.
Method B steps:
1. You have to pick each color ramp value manually from http://colorbrewer2.org/ .
2. Open the Layer properties and click on ‘Symbology’ tab in ‘ArcMap 10’.
3. Double click on one of the color symbol beneath ‘Symbol’ that gives you a ‘Symbol Selector’ window.
4. Click on ‘Edit Symbol’.
5. Click on Color box inside ‘Simple Fill’ area.
6. Click on “More Colors” which gives you Color Selector.
7. Choose RGB from Drop down box located in the top right.
8. Then, update values that come from Colorbrewer.
Voila Cheers!!!!!
I would like to recommend ‘Method A, because it is faster than Method B. (Does the same work but time consuming)
The author of color brewer, Cynthiya Brewer also published a book Designing better Maps in ArcGIS.

}
#loading {
<!--height:50px;
width:125px;

if(f.onload==null){
f.onload=function(){l.display='none'};
if(window.attachEvent)
f.attachEvent('onload', f.onload);
}
return true;

Convert PHP array into Javascript array
I got a chance to write a script that converts php array into javascript array.
Here it is..
<?php
$phparray= array(1,2,3,4,5);
?>
<script type="text/javascript" language="javascript">
var mydata = new Array (
<?php
for ($i = 0; ($i < count($phparray)); $i++) {
if ($i > 0) {
echo ",\n";
}
echo " \"";
echo $phparray[$i];
echo "\"";
}
?>
);
</script>
