I have a feature collection (grids) and an image. Any ideas on how to filter only features that cover the image (only the unmasked part of the image which appears in the map layer)? Here's the code: https://code.earthengine.google.com/16bfa4e762138a463bfe7bc3e2c738bd var biome = ee.Image("OpenLandMap/PNV/PNV_BIOME-TYPE_BIOME00K_C/v01"); var tropical = biome.updateMask(biome.gte(1).and(biome.lte(3))); var grid = american.coveringGrid('EPSG:4326', 500000); Map.addLayer(grid); Map.addLayer(tropical); For example, I want to select features only in the red part.

Based on var xx = resmap.add(navg), when I clicked the Google Earth Engine's inspector in the darker area (area with soil sand content >45%), I expected the Soil sand content percentage to be added to Soil water content percentage, which the total percentage will be shown in Sand + Water Content, and thus the total percentage then will be matched to the right color, accordingly, based on the colors on these lines: '' + '' + '' + '' + Unfortunately, that didn't happen. The Sand + Water Content will be the same percentage with Soil water content, despite the Soil sand content percentage is above 45%. So, what did I do wrong? And, any idea to fix it?
