What is Masking?
In processing EO data, masking is a very common operation to mark certain pixel locations as null values. For more discussion, see the RasterFrames masking page.
Sentinel-2
Let’s demonstrate the masking procedure for 3 bands of Sentinel-2 data. The measurement bands we will use share quality information from a separate raster band called the scene classification (SCL), which delineates areas of missing data and probable clouds. For more information on this, see the Sentinel-2 algorithm overview. The figure below tells us how to interpret the scene classification. For this example, we will exclude NO_DATA, defective pixels, probable clouds, and cirrus clouds: values 0, 1, 8, 9, and 10.

Using EOD, let's query some Sentinel-2 imagery. We will query the red, green, and blue measurement bands along with the SCL band. First, let's use Earth OnDemand to see what image collections are available to us.

This example will use the publicly accessible Sentinel-2 L2A collection. From the above DataFrame, this collection has an id of "sentinel2_l2a". Let's see which band names correspond to red, green, and blue.
In [3]:
band_info_df = earth_ondemand.item_assets('sentinel2_l2a')
band_info_df[
(band_info_df.eo_bands_common_names.isin(['red', 'green', 'blue'])) |
(band_info_df.asset_name.str.contains('SCL'))
].sort_values(['eo_gsd', 'eo_bands_common_names'])
Out[3]:

Now that we know the appropriate collection id and band names, let's make a small query around Dar es Salaam Tanzania using the 20m data. The common resolution across the SCL and measurement bands will simplify our work. We could also downsample the SCL band if needed.
In [4]:
catalog = spark.read.earth_ondemand_catalog(geo=Point(39.20, -6.80),
start_datetime='2019-09-01',
end_datetime='2019-10-01',
collections='sentinel2_l2a',
max_cloud_cover=10
)
band_names = ['B04_20m', 'B03_20m', 'B02_20m', 'SCL_20m']
df = spark.read.raster(catalog, catalog_col_names=band_names)
#keep only tile columns and rename
df = df.select(
col('B04_20m').alias('red'),
col('B03_20m').alias('blue'),
col('B02_20m').alias('green'),
col('SCL_20m').alias('scl')
)
HBox(children=(FloatProgress(value=0.0, max=3.0), HTML(value='')))
A NoData value is required to perform the masking. By default, Sentinel-2 measurement bands have a cell type of uint16raw. The "raw" qualifier indicates that there is no NoData value defined. By setting the cell types to uint16, we are setting the NoData value to 0. This is discussed in more detail here.
In [5]:
converted = df.select('scl',
rf_convert_cell_type('red', 'uint16').alias('red'),
rf_convert_cell_type('green', 'uint16').alias('green'),
rf_convert_cell_type('blue', 'uint16').alias('blue'))
Now let's use the SCL band to mask out unwanted pixels from the data bands.
In [6]:
bad_scl_values = [0, 1, 8, 9, 10]
masked = converted.withColumn('red_masked', rf_mask_by_values('red', 'scl', bad_scl_values)) \
.withColumn('green_masked', rf_mask_by_values('green', 'scl', bad_scl_values)) \
.withColumn('blue_masked', rf_mask_by_values('blue', 'scl', bad_scl_values))
Finally, let's inspect some tiles with lots of cloudy pixels.
In [7]:
masked.select('scl', 'red', 'red_masked') \
.filter(rf_tile_sum(rf_local_equal('scl', lit(9))) > 1000)
Out[7]:
| scl | red | red_masked |
|---|---|---|
