Pixel value differences in image downloaded through STAC api & Sentinel hub api

I downloaded same tile from AWS & Sentinel API. I compared pixel values for both and they differ by 1000. For example, consider red band. The value at 0,0 (row,column) for the image from Sentinel 2 is say 2242, then for same pixel the value for image from AWS is 1242. Why is this difference? From AWS & Sentinel API, I am downloading S2L2A product.

ValueError: During execution of task EuclideanNormTask

I am using a python scripts template instance and when executing the following workflow: workflow = LinearWorkflow( add_data, add_clm, NDVI, NDWI, NORM, add_sh_valmask, count_val_sh, *land_cover_task_array, concatenate, filter_task, linear_interp, erosion, spatial_sampling, save_s2) I got this error: When I used this code instead of the standard from eolearn.features import EuclideanNormTask , I think it got solved because. Does it mean that the built-in EuclideanNormTask is bugged? class EuclideanNorm(EOTask): """ The tasks calculates Euclidian Norm of all bands within an array: norm = sqrt(sum_i Bi**2), where Bi are the individual bands within user-specified feature array.

Error to download with AOI

Hi to everyone, I had some trouble when I tried to get an Sentinel 2 L2 > Tiff 32 > High resolution > WGS84 Geodetic system > with an AOI of 95,34 square km. So, just at advice, If you have this problem, just try to quit the AOI and then try to use the “mask” funtion on a GIS. I don’t know why the EO Explorer couldn’t use the AOI, but maybe this feature can be improve with this publication. Have a nice day.

Problem with the NDVI

I am following this tutorialLand Use Land Cover Classification and when trying to execute the workflow and download the S2 data, it failed and I got both of these logs: Any idea on what could be causing this?

Dockerfile eo-learn Rtree issue

Dear Sentinelhub, After creating a dockerfile for installation (see below for the Dockerfile) for installing the eo-learn package I ran into an error when using geopandas, in specific when trying to perform a spatial join.

Sentinel-1 image to elevation

Is there any way I can convert the “rugosity” of a VV(dB) Sentinel-1 image to elevation? I explain: in my research work, is very important to have the “rugosity” of the Landscape in a dem. For instance, the trees, are a limitation for the dispersion of some winds. Do you know any way to convert the trees height, different form the pastures, to instance, in a new dem?

Unable to access AWS tiles since 12/20

Up until 12/21 I could access Sentinel tiles as we’ve always been doing for a long time using this python script. Here’s an example – /Documents/scripts/sentinel_amazon_download_processor.py -s ‘2020-12-21’ -e ‘2021-01-07’ -t 18STE -f & We’ve checked everything on our end for issues. The script is still working to collect tiles before 12/21. Looking for assistance to see if there’s any connection issues may have arisen between AWS and our server. Thanks

SI_LULC_pipeline Further Questions

I had a few more questions regarding the EOPATCHES used for this example. I raised a question before and I was told that the blog post and the notebook are a little out of sync now so I am trying to get this pinned down. I was told that the EOPatches are currently 5kmx5km meaning 250,000 pixels per patch, what resolution pixel size are they. The old blog post said they were 10 m resolution is this still true? Also one further question, is there any sort of publications out using this data where I can compare my results to others? Thank you!

NDVI satellite image

Hi, I am trying to calculate NDVI from an area containing 26k plots of land. With ArcGIS I do a FLOAT and a DIVIDE, then I apply zonal statistics by plot. The dates are from October 2019 to October 2020. I get very bad plot plots of land. I have to say that in this area two satellite images are superimposed, could it be the cause of my results? I don’t know what error I have…May be with the WCS connection…Thanks.

How to use rasterio for rasterize and transformation of polygons?

Hi, I am new at this and I don’t quite understand how functions work. I have to transform a list of polygons that is in vector form into a raster mask, which should be geographically aligned with the NDVI image. I have the NDVI image and the list of polygons but I am not sure how to approach the problem. Thank you!

Halt a workflow based on condition

I would like to be able to halt a given workflow midway through processing if a certain condition is met, but without raising an error - I simply want to the linear workflow to not continue on to subsequent tasks. Is this possible? background: I’m running multiple workflows in an executor, one single Landsat scene per workflow. I want to be able to stop processing if the landsat scene fails a particular quality check.

Uitilizing WTMS through python

Hi. I’ve been successful in utilizing the python sentinelhub library for Wcs and Wms requests. Now I’d like to utilize WMTS, which I think is better for my needs. Is it supported in the python library? If so, is there an example code for reference?

FIS request Histogram values

Hi everyone I have a question about the statistical meaning of the values corresponding to each bin in the JSON object. For e.g., in this request-response below do the values (highlighted in bold) correspond to the mean/median/edges of the bins? I know that when using python API you have the choice between three methods of histogramming. But, what is the method of classification used to build the bins when using HTTP FIS request ? I am using this request to call the following JSON object: https://services.sentinel-hub.com/ogc/fis/{instanceID}?MAXCC=20&RESX=10m&RESY=10m&VERSION=1.3.0&CRS=EPSG:4326&BINS=5&TIME=2019-02-19/2019-02-23&LAYER=CHL-REDEDGE&GEOMETRY=POLYGON(({lat,lng})) The JSON object: {“date”:“2019-02-21”,“basicStats”:{“min”:0.3884204626083374,“max”:0.8388482928276062,“mean”:0.7900610220334081,“stDev”:0.04977570334911637}, “histogram”:{“bins”:[ {“value”:0.42235938608646395,“count”:10.0},{“value”:0.48521589961918915,“count”:11.0},{“value”:0.59281

Ndvi advanced script

Hello everyone, I would like to contact someone for the elaboration of a temporary script based on the ndvi. It is necessary that the script locate the date with the highest ndvi between the months of January and February for each pixel, and compare it with the date of the highest ndvi of the previous year in the same months, to obtain an anomaly of ndvi for each pixel. This is similar to the multitemporal script produced by the ibisa company, but my intention is to make another more advanced script. thank you
