GEE has the full National Land Cover Database and this has enabled a number of projects for me but I'm stumbling on a simple problem.



When I display the NLCD I can see that each point contains land cover values of all four epochs (1992, 2001, 2006 and 2011) but I'm not sure how to display them. As of now I basically just have the default display code but I'd like to show both 2011 and 2006.



var dataset = ee.ImageCollection('USGS/NLCD');
var landcover = dataset.select('landcover');
var landcoverVis =
min: 11.0,
max: 95.0,
palette: [
'5475A8', 'ffffff', 'E8D1D1', 'E29E8C', 'ff0000', 'B50000', 'D2CDC0',
'85C77E', '38814E', 'D4E7B0', 'AF963C', 'DCCA8F', 'FDE9AA', 'D1D182',
'A3CC51', '82BA9E', 'FBF65D', 'CA9146', 'C8E6F8', '64B3D5'

;
Map.setCenter(-76.356, 35.286, 8);
Map.addLayer(landcover, landcoverVis, 'Landcover');

          To add them all to the map, you can filter them for example by their system:index property and add them individually as images to the map.



          // load the four maps based on their year
          var years = ['1992','2001', '2006', '2011'];

          Map.setCenter(-76.356, 35.286, 8);
          for (var i = 0; i < years.length; i++)
          var year = years[i];
          var nameImage = 'NLCD' + year;

          Map.addLayer(landcover.filter(ee.Filter.eq('system:index', nameImage)).first(), landcoverVis, 'Landcover: '+year);



          You could also write down the filter four times with the name of the image ID written for each element, off course.
