Cloud filtering and PUs optimisation

Hello, Following the conversation we were having on this other topic regarding the optimization of processing units usage, i was wondering if, when retrieving data using sentinelhub/eolearn Python packages, it is possible to pass requests only on the scenes that aren’t cloudy ? On the exposed example we were seeing that more than half of the scenes from the passed requests were being thrown away following the filter_cloud_task. The maxcc argument from SentinelHubInputTask would seem on the paper to be suited for the job in calling only the cloud-free scenes but its documetation is rather scarce ; is there a place where its exact functioning is documented ? Also, and more broadly speaking regarding SentinelHubInputTask, it is described as a “Process API input task that loads 16bit integer data and converts it to a 32bit float feature”. I understand that this operation is done on the server side, explaining the x2 multiplicator. Thus, what would be the way to switch to 16bit data retriev

Build EOPatch with TPDI collection

Hello,I have ordered PlanetScope images through Sentinel Hub and I’d like to use them to conduct land cover classification.I have already conducted such a project using eo-learn library and Sentinel 2 imagery using the following command to collect S2 L2A imagery: add_data = SentinelHubInputTask( bands_feature=(FeatureType.DATA, 'BANDS'), bands = band_names, resolution=10, maxcc=0.8, time_difference=timedelta(minutes=120), data_collection=DataCollection.SENTINEL2_L2A, additional_data=[(FeatureType.MASK, 'dataMask', 'IS_DATA'), (FeatureType.MASK, 'CLM'), (FeatureType.DATA, 'CLP')], max_threads=5, config=config ) I tried to use similar command to create EOPatch from my Planet collection, replacing DataCollection.SENTINEL2_L2A with ‘byoc_collection’ (where byoc_collection = DataCollection.define_byoc(collection_id,is_timeless=False). However it did not work.Should such a comman

Multi spectral data for sentinel2-l2a

Hi, I am trying to save a combined tiff image for the following bands for a specific bounding box. When outputting just the RGB bands I am able to see the image without any issues. However, as soon as I add the other bands the image is no longer visible (it is black with a white bar in the middle). What am I doing wrong here? I tried playing with different scaling factor etc. Should be using different unit or scaling factor? function setup() {{ return {{ input: ["B02", "B03", "B04", "B08", "B11", "B12", "dataMask"], output: [{truecolor_str}], mosaicking: "TILE" }}; }} function evaluatePixel(samples) {{ var scaleFactor = 2.5; var b02_array = []; var b03_array = []; var b04_array = []; var b08_array = []; var datamask_array = []; samples.forEach((sample, index) => {{ b02_array[index] = sample.B02 * scaleFactor; b03_array[index] = sample.B03 * scaleFactor; b04_array[index] = sample.B04 * scaleFactor;

Coregistered Sentinel Images

Hello Sentinel hub team, I am thankful for your great work. I would like to know 1.If the sentinel-2 images that can be accessed through process API or any other available APIs are co-registered (by which I mean shift in pixels are corrected) 2.Also, are the indices (NDVI,NDWI etc.) calculated after applying the co-registration? Please let me know, Thank you

Harmonization Tool for Planet data

Hi, We are currently monitoring agriculture through sentinel 2 images, along with Planet daily images. The documentation tells about an Harmonization tool (https://developers.planet.com/docs/orders/tools-reference/) which harmonize PSScene surface reflectance products to Sentinel-2 values. However, when I click on the link there is no more information about it. I would like to understand how this harmonization works more in detail. We are now trying to develop indexes with mixed bands (bands from both satellites in one same index). I thank you for any information you could have about the topic. Thank you.

Ask a few questions,Expect expert answers

1、Sentinel-2 data is from ESA or Sinergise, and it is not certain whether it is official and complete？ 2、The variety of some data is incomplete. For example, MODIS has more than ten types of data open to the public, but there are only five categories in the AWS Marketplace, and there is no data updated daily.How do I get the full variety of data? 3、The path level of some data (sentinel-3, -5P) is not accurate to the geographical location level (such as latitude and longitude, row number, grid, etc.), and it is difficult to download directly to a certain range of data. 4、Whether you can provide some data description documents in AWS Marketplace, some data is different from the official website, and it is difficult to use.

Is it possible to extract image clippings of e.g. 256x256 from this shapefile of points?

Dear forum members, I am recently joining the sentinel hub environment, and would like to get some help… I have a shapefile of approximately 6000 points. Is it possible to extract image clippings of e.g. 256x256 from this shapefile of points? Is there a way to do this? My interest in obtaining these images in clippings with those dimensions, is to generate a dataset of images and make the annotations for segmentation of instances with other computer vision tools, example labelbox. Is there any way to do the image labeling, with an object detection/image segmentation approach? Please, I hope you can help me, thank you!

Sentinel-2 L2A have no projection info

Hi, I’m wondering why the geographic projection info of L1C images is lost in the L2A. For instance, running gdalinfo /vsis3/sentinel-s2-l1c/tiles/33/T/VE/2017/3/29/0/B04.jp2 shows that the image is georeferenced in UTM zone 33N. With the same image in L2A, gdalinfo /vsis3/sentinel-s2-l2a/tiles/33/T/VE/2017/3/29/0/R10m/B04.jp2 shows no projection info. As far as I understand, transforming L1C into L2A involves radiometric corrections only and it shouldn’t affect the geometry. Am I missing something?

Show Legend on Map

Hi, I am using your services to show different layers on the map (NDVI, LAI etc.) I also want to show a legend with values for better understanding of the satellite imagery. I tried following your tutorial (How can I define a custom legend?), but I always get an error calling this API: https://services.sentinel-hub.com/ogc/wms/instanceId?service=WMS&request=GetLegendGraphic&layer=NDVI The error I get is 404: message: “Not Found” servlet: “org.glassfish.jersey.servlet.ServletContainer-5fa9247b” status: “404” url: “/ogc/wms/{redacted-instance-id}” The instanceId is correct, since I tried other requests and it works fine

Accessing satellite metadata file from Sentinel hub API

I am using the OGC API for various data downloads like Landsat NDVI, DEM and Sentinel. In my current process we also need to extract the Landsat metadata information like sun elevation angle and relative sun earth distance. How can we access that? there is no clear example available for such kind of information calling.

PlanetScope data image with gaps lines

We ordered planet images for a particular region via the request builder tool. The AOI was split into multiple PlanetScope tiles So we ordered different segments of tiles so as to cover our whole AOI. On requesting the third party PlanetScopeData data from sentinel process API for the AOI. We are getting the data but there seems to be a line data gap in the downloaded image. This is when it was ensured that AOI was getting covered by the respective tiles which can easily be checked while using the requests builder portal. Any possible solution for this. Is this some processing issue that can be rectified with the Process API ? Gap Image AOI KMLrizhou-1.kml (1.9 KB)

PlanetScope order completion delay

The questions are about PlanetScope the order completion. We have experienced that when we make bulk orders for PlanetScope data via sentinel hub API and simultaneously trying to get the list of the pending orders from the PlanetScope’s own API. We found there the orders stats for running and queued orders come out to be 0 while the orders were still pending on the sentinel hub API end. The API used to check the stats is provided below and PlanetScope account credentials were used to access the information. Aggregate Orders Stats GET https://api.planet.com/compute/ops/stats/orders/v2 I have few questions listed below which need answers Is this a normal scenario where some other processing is taking time going on the sentinel hub end to make the PlanetScope order data available? Are there any stats regarding what is the expected delay between image order completion on PlanetScope and the same data becoming available through the sentinel hub API? In case if there is some delay whether t

Harmonized Landsat Sentinel (HLS) QA decode

Hello. I use statistical API with HLS data. I take the vegetation index. Need to decode QA according to this user guide. I don’t understand how to do it in evalscript. How to decode QA into comprehensible variables? “maxcc=0.8” - not used because as I understand it applies to the whole tile and not the area of interest I need to determine the percentage of pixels that I am not interested in. The script example is not correct, I added it to make it more clear what I need. function setup() { return { input: [{ bands: [ "Red", "NIR_Narrow", "QA", "dataMask" ] }], output: [ { id: "data", sampleType: "FLOAT32", bands: 2 }, { id: "dataMask", bands: 1 }] }; } function evaluatePixel(samples) { let index = (samples.NIR_Narrow - samples.Red) / (samples.NIR_Narrow + samples.Red); let cloud_percent = 0; if (samples.QA == 1) { cloud_percent = 1; } else

Empty response with Landsat 8 Thermal Band

Hi! I am trying to get thermal data from the Landsat-8 Level 2 Collection using the script you provide: //VERSION=3 function evaluatePixel(samples) { return [samples.B10, samples.dataMask]; } function setup() { return { input: [{ bands: [ "B10", "dataMask" ] }], output: { bands: 2, sampleType:"FLOAT32" } } } But both the preview in the dashboard configuration and the response give back files with no data. What am I missing? Thank you!
