Download raw band

Hello To download Sentinel 2 raw band images, we suggest choosing another method (custom scripts) to delete pixels without data. It is not right to convert the raw image band into two bands! This makes it difficult for those who have designed and manufactured their algorithms on a single raw band basis. Please solve this problem or leave the download of this feature as the user chooses

Sentinel 1 acquisitions misaligned

Thanks in advance for any feedback. Sentinel 1 acquisitions on the same track over the same area at successive times (12 days apart) the one swath is skewed. Seems as if the skewing started in July 2019 and ended by February 2020. After February 2020 the swaths went back to being rectangles like they were before July 2019. Swaths in image from snap: S1A_IW_SLC__1SDV_20190625T164639_20190625T164706_027838_032491_C852 S1A_IW_SLC__1SDV_20190707T164640_20190707T164707_028013_0329E7_3559 I’m hoping someone can help me since this seems to be the cause of my time-series sub-regions being misaligned. Is this likely to happen or is this a problem with the meta-data in the acquistrions?

Strange result from API

Hello! I am using SentinelHUB python API to get the data for AOI. The result is strange as follow: I wonder if I am doing something wrong or what?! I should also mention that for other areas the result is OK. Interestingly, others have done for the same area with the same interval and the result is fine. evalscript_true_color = “”" //VERSION=3 function setup() { return { input: [{ bands: [“B02”,“B03”,“B04”,“dataMask”] }], output: { bands: 3 } }; } let minVal = 0.0; let maxVal = 0.4; let viz = new HighlightCompressVisualizer(minVal, maxVal); function evaluatePixel(samples) { let val = [samples.B04, samples.B03, samples.B02]; val = viz.processList(val); val.push(samples.dataMask); return val; } """ request_true_color = SentinelHubRequest( data_folder='./outputs', evalscript=evalscript_true_color, input_data=[ SentinelHubRequest.input_data( data_source=DataSource.SENTINEL2_L2A, time_interval=('2020-04-01', '2020-06-30'),

WMSRequest TYPENAME=S2.TILE for SENTINEL 5P data

Hi there, I am trying to access with my python scripts data from Sentinel5P (in particular, NO2 products). I am using the same syntax as in the tutorials, with Sentinel2, that is: three_band_req = WmsRequest(layer=“NO2”, bbox=canary_bbox,* time='latest',* width=512,height=856,* instance_id=INSTANCE_ID)* But i keep obtaining a 400 client error, with the typename error: “TYPENAME=S2.TILE not found!” This rises a couple of questions. Does that S2.TILE refer to Sentinel2? If that is the case, how can I refer in my data to Sentinel5P products? The INSTANCE_ID corresponds to one with a configuration of Sentinel5P, but I wonder if maybe I have to edit some other parameter of the function ‘wmsRequest’ to explicitly refer to S5P. In case S2.TILE does not refer to Sentinel2 products, how can I solve this issue? Thanks in advance and kind regards, Ignacio

Modify Maximum sensing time PlanetScope / timeRange.to

Hi, I noticed that the images of planetscope for this week were empty, so I checked my planetscope subscription and saw that there was a maximum sensing time (last week). When I setup the request builder for my area I left the ‘timeRange.to’ date empty. What will happen if I delete my running subscriptions (well, they are finished now) and my quota? Will I have to topup again? Can I instead adjust the maximum sensing time in my collection?

S2 L2A - Select less cloudy patches of an Area Of Interest over a time interval

Hi there, I am a new to sentinel hub and a bit lost with the whole ecosystem. I am a python developer and I was wondering if I can select less cloudy patches of an Area Of Interest over a time interval. I didn’t find this in sentinelhub-py & eo-learn documentation. For example, I would like to get a Sentinel-2 L2A tiff file for a country composed by the less cloudy EOPatch found over a time interval of 2 months. Thank you for your help

400 Client error for request generated by sentinel-hub library

I am again experiencing the error I reported here: Repeatable (retry always fails) HTTP 500 errors for certain dates Bugs & Features I am running large numbers of WCS requests through the EO-learn library. I request LAI time series data for areas of 0.1-10 hectare land parcels for ca. 6 month time intervals. Occasionally (ca. 1% of the time), the EO learn workflow.execute() call will fail because of a HTTP error: “DownloadFailedException: During execution of task S2L2AWCSInput: Failed to download from: https://services.sentinel-hub.com/ogc/wcs/?SERVICE=wcs&BBOX=660977.0343447%2C5689713.093569177%2C661295.2431077849%2C56900… The only difference, I get the error code 400 not 500. The code I use is the same as in the above linked topic.

Sentinel-1 SAR imagery may need filtering

Dear forum SENTINEL HUB is a great product indeed but I was wondering if the Sentinel-1 SAR GRD VV [db] orthorectified images available are filtered for speckle using e.g. a 5x5 Lee Filter and/or a 3x3 median filter? all S-1 SAR VV [db] orthorectified imagery I have browsed so far on the app appear grainy - and as a result, in my opinion, of little use. Below a quick example between a SNAP processed S-1 SAR image and the same image offered by SENTINEL HUB - if you ignore the land mask, and only look at the brightness difference over the ocean, the difference is evident. Is it possible for SENTINEL HUB to either filter the S-1 SAR images offered as VV in db or add another layer for the users? Thanking you in advance for your valuable help.

Not able to use Planet data in sentinel hub request builder?

I have planet-4 and planet-8 data in my sentinel hub account which can be accessed on the Dashboard using My Collections but in the request builder, I am not able to use that data. No matter what script or time range I use from custom scripts, I get a black image as output. Does the catalog API work for planet data? Can somebody guider with further steps?

Equal Point Sampling

Hello forum@sentinel hub, I have been trying to make a custom version of the example in land-cover-classification-with-eo-learn tutorials. Unfortunately I find that the result of my classification is that PointSamplingTask only finds 3 feature classes, out of 10 in total. As I understood in the example it takes 40.000 pixels from 1.000.000 pixels. I have tried with the PointSamplingTask set to 800.000 pixels as an experiment, and it did find more feature classes but it caused the GBM machine learning algorithm to overfit. Therefore my question: is there a way to set a minimum amount (for example 20.000 pixels) for every unique feature class for the PointSamplingTask? Thanks a lot in advance, Thijs

Standardising colour ramp for NDVI

Kia ora - hello from Aotearoa New Zealand I was very fortunate to meet Grega Milcinski when he spoke at the “What on Earth” colloquium held at Te Papa, Wellington recently. Before he showed the use of the Sentinel-Playground, I had been downloading whole scenes from the US Geological Survey’s EarthExplorer, then processing layers through a geospatial raster calculator (in Quantum GIS) to then return a Normalised Difference Vegetation Index (NDVI) product. The Sentinel Playground is a real step up in democratising earth observation data; full credit to the Sinergise team. I asked Grega if the colours of the NDVI product could be standardised - “have I got my colours correct?” [I also ask as some gentlemen are colour-blind, so I need to ensure that the graphic is telling the true story about the data]. Grega’s informative reply included this piece of code, which it’s straightforward to use (Thank you Grega!) "Code: let ndvi = (B08 - B04) / (B08 + B04); if (ndvi<-0.2) return [0,0,0

Detecting Fishing Trawlers on open seas

Bottom trawlers in Asia cause significant damage to marine areas including protected marine areas. Wonder if it is possible to detect presence of trawlers in open seas off the coast region of southeastern countries of Cambodia, Thailand, Malaysia. The size of bottom trawlers tends to be quite small ( 40 to 60 feet wide and 8 to 10 feet tall) and doesn’t have radar reflectors or any AIS system per se.

PlanetScope search not working?

Dear Sentinel Hub team, I have not done Third Party searches for a couple of months and now I’m having some problems, that is, I don’t find any product. I have also tried to use the same query of the link (with the appropriate PlanetApiKey) docs.sentinel-hub.com Examples of Third Party Data Import Follow these examples to import commercial third-party data into Sentinel Hub. but also in this case the features of the response are just empty. Do you have an idea what the problem might be? Best regards, Emanuele
