Remove certain tiles from batch request before starting job

Hi everyone. I have a batch api request written in python. I currently do the following: Create a batch api request. Analyse the batch request above to get information about the tiles. Start the batch job to initiate processing. This works fine. Now I want to do the following: Create a batch api request. Analyse the batch request to get info about the tiles. Using the tile ‘name’ property from the tile information provided after analysis, programmatically exclude tiles whose tile names already exist in my s3 bucket. Start batch job only for tiles that do not exist (I’m trying to avoid redownloading existing tiles from the past). I have a problem with step 3 above. I haven’t come across a function in ‘sentinelhub’ python library for removing specific tiles (eg. by tile id) before starting a batch job. Is this possible?? Thanks.

Configuration for WMS full resolution satellite data with all bands

Which is the best request parameters to obtain the raw data with max resolution? so far, we have set the following: m_wms_request = WmsRequest(layer=‘FALSE_COLOR’, custom_url_params={CustomUrlParam.EVALSCRIPT: all_bands_script}, bbox=mybox, time=‘2017-07-18’, width=980,image_format=MimeType.TIFF_d32f, instance_id=INSTANCE_ID)

Wrong EVI values

Hello, i’m getting 0 to 250 tiff values when I run this Layer script in QGIS. What should I add to get -1 to +1 values as index? Regards //VERSION=3 function evaluatePixel(samples) { let val = 2.5 * (samples.B08 - samples.B04) / (samples.B08 + 6 * samples.B04 - 7.5 * samples.B02 + 1); return [val, samples.dataMask]; } function setup() { return { input: [{ bands: [ “B02”, “B04”, “B08”, “dataMask” ] }], output: { bands: 2 } } }

BatchProcessing + TimeSeries

Hi everyone, I have an enterprise account, I’ve just started developing using sentinel2 data and python, I’m finding it quite overwhelming. I’ll go straight to the point: I need to create a ML model, using input data from 2 countries. I’d like to use all raw bands data from several years (as a time series) and apply post processing locally. What’s the best (and cost-efficient) way to do so? To go deeper, that’s exactly the data science case explained here: (Large-scale data preparation — introducing Batch Processing | by Grega Milcinski | Sentinel Hub Blog | Medium) I’ve already tried a few alternatives, but I don’t get what’s the “right one”: → “naive” approach, splitting big area into smaller tiles then looping standard SH requests over every tile and time frame → Use Batch Processing, but as it only returns one image per time period, loop it over small time frames. → Use multitemporal EvalScript with Batch Processing (though I have almost zero knowledge about JavaScript) → Use e

Image_format = MimeType_d32f

‘‘image_format = MimeType_d32f’’ works properly in the system that has been developed 2-3 years ago but it doesn’t download the data now when ‘WcsRequest’ is used and even I tried changing the version of sentinelhub to the previous version(3.4.4) on which the system used to download the data using ‘MimeType_d32f’ image format. Please help me with this issue.

NDVI Images Quality

Hi, I am having problems with the quality of the result image of my requests. In detail in order to obtain a quite decent result i had to create a quite big bbox (see attachment), but for smaller bboxes the quality is really bad. Is there something i can do to improve it? Here is an example of a request: https://services.sentinel-hub.com/ogc/wms/{instance_id}?SERVICE=WMS&REQUEST=GetMap&VERSION=1.1.1&LAYERS=VEGETATION_INDEX&MAXCC=20&WIDTH=640&HEIGHT=640&SRS=EPSG:4326&BBOX={bbox}&GEOMETRY=POLYGON(({geometry }))&FORMAT=image/png&TRANSPARENT=1&TIME=2021-04-01/2021-04-09

Sentinel 2 bad resolution

Hi, I cant get the sentinel 2 original resolution of 10m when I download a image by croping. I choose the high resolution, I need to download the band so I choose TIFF 32 bits, not a jpg image. But in projected resolution I never get less than 40m/px. I want to know how can I download the original resolution? Thanks.

Request for SENTINEL1_IW_ASC is empty

This request returns two empty results (all zeros o NaNs). But I’ve confirmed in EO explorer that this data is available pre 2017 if the EO cloud option is selected. Am I getting empty results because I need to enable EOClloud in my SentinelHubRequest somehow? If so I can’t find how to do this. I see in the S1 docs that: Mosaicking SIMPLE and ORBIT mosaicking types are supported. But what if I want to download the time series without mosaicking? The way I understand mosaicking is that images from different times will be stitched together into a single image, but I want the time series of individual images. Also, when I select Orbit Direction in the request builder, I get SENTINEL1_IW_ASC as the data_collection. Is there a way to get both Ascending and Descending? from sentinelhub import SentinelHubRequest, SentinelHubDownloadClient, DataCollection, MimeType, DownloadRequest, CRS, BBox, SHConfig, Geometry config = SHConfig() # confusing SH-specific script for getting outputs is descri

Get number of images in BYOC without counting

I have written a script based on this tutorial that access BYOC collection and creates GeoDataframe with data about all the tiles. This is how I do this: byoc = SentinelHubBYOC(config=config) my_collection = byoc.get_collection(instance_id) col_name=my_collection['name'] tile_iterator = byoc.iter_tiles(my_collection) collect_tiles=[] for i in np.arange(0,num_imgs,1): collect_tiles.append(ByocTile.from_dict(next(tile_iterator))) gdf = gpd.GeoDataFrame(collect_tiles, geometry=[t.cover_geometry.transform(CRS.WGS84).geometry for t in collect_tiles], crs="epsg:4326") gdf_1=gdf.reset_index() My problem here is that I need to know the exact number of tiles I have in my collection for this script to work (the variable “num_imgs”) . My question is, is there any wat that I can get my BYOC size within my code without use it as a known parameter? Thanks in advanced 🙂

Differences between _parse_features and get_feature_parser

I came upon a version issue between different eo-learn versions. The issue was that the _parse_features function that was removed along time ago, does not function the same way as the parse_features function that was added included with the get_feature_parser: This photo is from eo-learn 1.0.0. It states that _parse_features was replaced with get feature_parser. Once again I am trying to repurpose a the CloudMasking class within the tiffs_to_eopatch.py file within the field-delineation Github. class CloudMasking(EOTask): """ Compute cloud mask from SH cloud probability CLP data map """ def __init__(self, clp_feature: Tuple = (FeatureType.DATA, 'CLP'), clm_feature: Tuple = (FeatureType.MASK, 'CLM'), average_over: int = 24, max_clp: float = 255.): """ :param clp_feature: Feature type and name of input CLP mask :param clm_feature: Feature type and name of output CLM mask :param average_over: Parameter used ot smooth the CLP data map

Fail to download image in EO Browser when clipped with complex polygon

I am using a GeoJSON file of the border of Berlin to clip a SENTINEL-2 L1C image. But when I try to download my image I get the Google Chrome error message: This site can’t be reached. services.sentinel-hub.com unexpectedly closed the connection. However, if I draw a basic rectangle or less complex polygon, the download works well. So I assume it has something to do with the file format or the complexity of the polygon. Does somebody know what I can do about that?

Sentinel-2 L2A ingestion outage

On 26th of February ESA introduced S2 L2A evolution product, which caused a breaking change in the ingestion process. We are making changes to the software to handle all these changes (different structure, file-names, etc.) but it will take a couple of days more to finish. We will report it here, when process is complete and ingestion running once again.

Sentinel 2 12 bands in 10m res
