Canopy cover

Map canopy cover for the period 2000 – 2017

step 1: add a geometry to the map

step 2: add the area of interest

// set the area of interest
var chl = ee.FeatureCollection("users/servirmekong/Vietnam/CHL_Boundary").geometry();

step 3: import the tree canopy cover image collection

// import tree canopy cover
var cc = ee.ImageCollection("projects/servir-mekong/yearly_primitives_smoothed/tree_canopy");

step 4: set period of interest

// set year of interest
var year = 2017;
var startDate = ee.Date.fromYMD(year,1,1);
var endDate = ee.Date.fromYMD(year,12,31);

step 5: filter for date to get the image

// get image for the year
var ccImage = ee.Image(cc.filterDate(startDate,endDate).first());

step 6: add the image to the map

Map.addLayer(ccImage.clip(chl),{min:0,max:100,palette:"white,lightgreen,green,darkgreen"});

step 7: add a chart to get the timeseries.

print(ui.Chart.image.series(cc, geometry, ee.Reducer.mean(), 30, 'system:time_start')
.setSeriesNames(['cc'])
.setOptions({
title: 'Canopy cover',
lineWidth: 1,
pointSize: 3,
}));
