GEE: Having trouble creating cloud free imagery and applying NDVI calculation to NAIP, Sentinel 2, and L8 collections

0

I'm trying to get cloud and shadow-free (or as close to cloud free) scenes for Landsat 8, NAIP, and Sentinel 2 (specifically sentinel 2 10 meter resolution), and then apply the NDVI calculation to each set.

After that, I'd like to look at those values within specific polygon geometries I've created, but that's a separate thing I'd like to try on my own first!

I'm fairly new to GEE, and though I've watched the tutorials I still have some trouble with basic things it seems. Any help would be much appreciated!

Here is just the portion I have so far for Landsat 8, though it's not running error-free.

// add three imagery layers to neighborhoods and filter date

var l8filtered = landsat8.filterDate('2016-10-01', '2016-10-31'); 

                         .sort('CLOUD_COVER');

                         .first());



// send to console/add to map

print(l8filtered, "l8 filter")

Map.addLayer(l8filtered,{},"L8")



//create NDVI image

var l8_ndvi = l8filtered.normalizedDifference(['B5','B4']);

Map.addLayer(l8_ndvi,{min:-0.2, max:0.5, palette:['FFFFFF', '339900']},'L8 NDVI');
