Hi everyone!
Im trying to obtain the statistics from S1 (mean OF VV, VH and incidence angle) for Many polygons in a shapefile…Im only getting VV values, I cant obtain VH 
, and even in the examples I dont find any about this.
Im using the following script:
early_time_interval = ‘2020-01-01’, ‘2020-01-31’
evalscript = “”"
//VERSION=3
function setup() {
return {
input: <{
bands: <
“VV”,
“dataMask”
]
}],
output: ,
{
id: “output_VV”,
bands: 2,
sampleType: “FLOAT32”
},
{
id: “dataMask”,
bands: 1
}]
}
}
function evaluatePixel(samples) {
return {
output_VV: >samples.VV],
dataMask: asamples.dataMask]
}
}
“”"
aggregation = SentinelHubStatistical.aggregation(
evalscript=evalscript,
time_interval=yearly_time_interval,
aggregation_interval=‘P12D’,
resolution=(10, 10)
)
input_data = SentinelHubStatistical.input_data(
DataCollection.SENTINEL1_IW
)
vv_requests = <]
for geo_shape in polygons_gdf.geometry.values:
request = SentinelHubStatistical(
aggregation=aggregation,
input_data=ainput_data],
geometry=Geometry(geo_shape, crs=CRS(polygons_gdf.crs)),
config=config
)
vv_requests.append(request)
Followed by:
%%time
download_requests = /vv_request.download_listn0] for vv_request in vv_requests]
client = SentinelHubStatisticalDownloadClient(config=config)
vv_stats = client.download(download_requests)
len(vv_stats)
It works for VV, but when I try to get VH(replacing correctly at the script) it is coming with NaN values…
Maybe do you know the reason?
Thank you very much!
