As promised in the last post, we will be having a look at a
very simple example that will help us understand how we can use the
weather layer effectively in our Google Map applications using the
Google Maps API v3. The weather layer is basically a combination of
2 layers - the Weather Layer and the Clouds Layer. The weather
layers displays the weather icons and the temperature corresponding
that icon whereas the clouds layers displays the cloud cover across
the globe. We can choose to display or hide any of these layers. Let
us now dive into a very simple code that will help us understand the
basics of the Weather Layer library today.
The output of the above code will appear as seen in the result section above. You will find a map centered at "India" with both the weather
and cloud layers enabled!
Most part of the above code is similar to most other examples you will find on this site. There are just 2 new and important things in this code. Look out for the variables "weather" and "clouds". The variable weather basically holds a new object of the type weatherLayer and has a property called temperatureUnits. The value of this property can either be in degrees Celsius or Fahrenheit. The clouds basically holds a new object of the type cloudLayer. We can choose not to display either of these layers by commenting out the "setMap(map)" lines from the above code.

Like rest of the examples seen here, this is another simple,
easy-to-understand example code using the Google Maps API v3. If you
have any queries regarding the code, please feel free to drop a
comment and I will be happy to help you with the code.
my basics in GIS are very weak..hw 2 enhance them stepwise...plz suggest
