Vectorize a watermask to create a shapefile of a lake.
Import the JRC Yearly Water Classification History v1.0 (1984-2015), create a box and geometry for the area to focus on and use the script below:
// filter for date var mymap = jrc.filterBounds(geometry).filterDate(ee.Date.fromYMD(2013,1,1),ee.Date.fromYMD(2015,12,31)).sum(); // set viz var viz = {min:0, max:1, palette:['0060fc']}; // all pixels greater than 40 var myMask = mymap.gt(40) // mask the pixels mymap = mymap.updateMask(myMask) // create clipped water layer with 0 and 1 var water = mymap.where(mymap.gt(0),1).clip(box) Map.addLayer(water,viz,"water mask") // make vector layer var vector = water.reduceToVectors({geometry: Map.getBounds(true), scale: Map.getScale() * 0.5 }) // add the vector layer Map.addLayer(vector, {}, 'vector map') // create point layer var points = ee.Geometry.MultiPoint(vector.geometry().coordinates().flatten()) // add the points Map.addLayer(ee.Image().paint(points), {palette:['ffffff']}, 'points')

Hi, how to export data
