Arctic Sea Ice Resampling

Question asked by wbolsen on Nov 12, 2014

Hello All,

I am using some Landsat 8 imagery of Arctic Sea Ice and am trying to create polygons of the individual ice chunks. The problem is the small sections connecting  the larger pieces.  They act as an "ice isthmus" and I can't seem to sample them out. 

Does anyone have a good method of re-sampling the raster to remove these ice connectors while preserving the basic shape of all ice chunks?  I have created an 11 band composite image using the image analysis tools and then an ISO Unsupervised Classification binary raster consisting of Ice and Water.  The Image classification tools do a great job of classifying cells. (Below is a swipe screenshot showing ice as blue)  I've then tried a number of the raster generalization methods but most will remove the smaller ice chunks or reduce the size of the larger ice floes.  Any help would be appreciated!  I can send the TIFF if it helps!  Thanks, Bill.
