masking of features outside a polygon

[SourangsuChowdhury]

I have a shapefile of India on which I have interpolated some data of AOD, which consists data points of the neighbouring countries and oceans and seas surrounding india also. I need to mask the features ouside the shape file of India, I tried the masking tool in cartography toolbox...........PLEASE HELP..

Assuming that the data you wish to mask by the India shapefile are features, use Clip in the Analysis toolbox to clip the input features to the India shapefile.

If you have interpolated points to create a raster, then you can use Extract By Mask in Spatial Analyst to perform a similar operation.
