Toby, it looks like the only usable LANDSAT layers are going to be the greenest pixel ones, as imperfect as they are. Median pixel and everything else I've tried is cloudy as hell (or heaven, I guess is cloudier). Anyway, here's what we're looking at:

var composite = ee.Image(ee.ImageCollection('LANDSAT/LC8_L1T_ANNUAL_GREENEST_TOA') .filterDate( Selection_Year + '-01-01', Selection_Year + '-12-31') .first());

Matt, found a couple of questions:

  1. Can you give me a landsat5 link? Also, what's is the cut off year between the two?
  2. Can you give me some visualization params for a color scheme? i.e. { min: ?, max: ? , palette: "#CSS,#CSS,#CSS"}

Toby,

Here's the code I used for Landsat 5

var composite = ee.Image(ee.ImageCollection('LANDSAT/LT5_L1T_ANNUAL_GREENEST_TOA') .filterDate( NDVI_Year + '-01-01', NDVI_Year + '-12-31') .first());

And, since it's a 3-band image, don't need to specify a palette. Just something like:

Map.addLayer(composite, {'bands':['B3', 'B2', 'B1'], min:0, max:0.25});
