Thank you in advance.

is this contour data more detailed than the terrain layer in google maps? like maps.google.com/… – Mapperz Jun 21 '12 at 13:33
    
Yes @Mapperz . We have only data for specific area that is coordinate and the height value for the the coordinate coming from database – Gunner Jun 22 '12 at 11:52

Would generate the contours to KML or GeoJSON and add as a layer. GlobalMapper can create the contours from points with height elevation - bluemarblegeo.com/global-mapper – Mapperz Jun 22 '12 at 13:13
    
Thanks @Mapperz Instead of using third party tool is there any java-script or C# code that can convert the x,y,height to shp file. – Gunner Jun 22 '12 at 14:01
    
@Mapperz even something like heat map that plot the values in different color layers might work, i guess. – Gunner Jun 22 '12 at 14:14
