I am using [sample] to compute a table from raster layers. Input raster layers: 1st layer_A with 50 counts (1 ,or else 0) 2nd layer_B with 10 counts ( 1 or 0) input location: layer_C with 1000 counts The data that i want to get is: 1st column have 1000 rows with xy coordinate from layer_C 2nd column contained 50 rows (out of 1000 rows) that have value 1. same for column 3, containing 10 rows that have value 1. problem is, all i will get was (eg) the second column have 500 rows with value=1 rather than what it supposed to have, 50 rows/counts. Is there anything that i am missing here? Do i need to check anything or having any standard checking protocols before i use the [Sample] tool? Many thanks guys. Guys, i managed to get the table i want by opt saving the gdb file in the default location. But if i alter the location where the gdb will be saved, the table computed will be very strange... i wonder if this is a bug?.

You can use Eliminate Polygon Part Or Multipart to Singlepart and delete or definition query out the smaller islands. Many thanks, mzcoyle! The Multipart To Singlepart (Data Management) works!!!:D I have tried the first one but unavail though.

Hi all. I have downloaded administrative boundaries from www.gadm.org. I managed to create a feature layer using[Select Attribute]. Then, I want to remove the small islands and keep only the mainland. The problem is, i have multipolygon in 1 shapefile, with different fields of same value, no matter where i click on the layer. Any idea how can i remove the small islands and keep the mainland? Many thanks.
