Using Planet in Google Earth Engine
Visualizing your Imagery
True Color
You may see black footprints when you first Map.addLayer your image collection. To generate a true color visualization try adding the following visualization parameters to your addLayer request.
Planet's imagery bands are ordered: Blue, Green, Red, NIR.
Map.addLayer(imageCollection, {"opacity":1,"bands":["B3","B2","B1"],"min":405.79,"max":4499.71,"gamma":2.331})
False Color
To generate a false color infrared image, simply swap around the bands.
Map.addLayer(imageCollection, {"opacity":1,"bands":["B4","B2","B3"],"min":405.79,"max":4499.71,"gamma":2.331})
Band Math
NDVI
This code sample runs on an image (as opposed to an imageCollection) and uses GEE's normalizedDifference function to generate a NDVI output from Planet's NIR & Red spectral channels.
Map.addLayer(image.normalizedDifference(['B4', 'B3']).rename('NDVI'), {min: -1, max: 1, palette: ['blue', 'white', 'green']});
Working with cloud masks: UDM2
Visualizing usable pixels
Ordering a Planet imagery bundle like analytic_sr_udm2 will append Planet's usable data mask 2.0 (udm2) bands to your 4-band PlanetScope images, resulting a 12 band image in Earth Engine.
Map.addLayer(image.select('Q8'), {min: 0, max: 1, palette: ['black', 'white']});
