How to find mountain icelands from elevation/contour map

Discussion created by pk.paudel on Mar 22, 2013
Hello everybody,
I am trying to prepare a map of mountain islands from contour map or elevation zone of Himalaya. To be precise, I want to find a closed counter or elevation zone that does not have higher elevation zone in ArcGIS environment. By doing so, I am expecting find out a number of polygons (mountain islands if we forget lower elevation zone). Are there any scripts or tools available for ArcGIS 9.2 environment? Any suggestion will be highly appreciated. Thank you.
