Get large area as one image

I want to get large image as one image. Question: bbox = [7200979.560689886, 7514065.628545968, 5009377.085697314, 5322463.153553395] bbox = BBox(bbox=bbox, crs=CRS.POP_WEB) bbox = bbox.transform(crs=CRS.WGS84) wms_request = WmsRequest( layer=‘TRUE_COLOR’, bbox=_bbox, width=512, height=512, maxcc=0.3, custom_url_params={ CustomUrlParam.SHOWLOGO: False, }, image_format=MimeType.JPG, config=config)

Help with time ranges in API

When we given start and end time dates for quering date in sentinal-hub api, have read that “If two time points (start and end of the time range) are specified, the service will return a mosaic of the images from that time range” Mosaic is mostly done to fuse mostly non-overlapping regions into a single image, but here our region will be present in many images and have a time-series values but only 1 image is returned. It will take on so many different values in this time period as well. Don’t understand how values for overlapping region among the many images are estimated. Are they averaged? How to interpret this statement? Also is there a way to get the capture date of the image returned? Currently get_data() returns only a list with the image array. The request made is from the examples: request_true_color = SentinelHubRequest( evalscript=evalscript_true_color, input_data=[ SentinelHubRequest.input_data( data_collection=DataCollection.SENTINEL2_L1C,

Sentinel-1 and Sentinel-2 S3 Inventory files

Hi all, S3 Inventory has been turned on for all the Sentinel buckets available via the AWS Public Datasets program. This includes sentinel-s1-l1c, sentinel-s2-l1c, sentinel-s2-l2a. The S3 bucket that contains these inventory files is sentinel-inventory and is in the eu-central-1 region. These inventory files will provide, on a daily basis, the inventory of all files in the buckets along with their size and last updated time. More information on S3 Inventory files here.

Eo-Learn Bandwise Median & Percentiles over Time

Hey there, I am currently playing around with the excellent eo-learn library and I am wondering if there is any EOTask or workflow that extracts bandwise mean and percentile values over the entire timeperiod? I found MapFeatureTask, but I am struggling with accessing the single bands from my data set inside the function. So what I am currently doing is something like a nested loop in which I loop over all bands first and execute the workflow from new for each patch. Is this the way to go? Or how would you go on about this? BAND_NAMES = ["B02","B03,"B04","B05","B06"] #loop over band bands, and define workflow from new for each band for b in range(len(BAND_NAMES)-1): print(BAND_NAMES[b]) #extract band from my S2 Band Stack move_band = ExtractBandsTask((FeatureType.DATA, 'S2_L2A_BANDS'), (FeatureType.DATA, BAND_NAMES[b]), [b]) #calculate mean calc_mean = MapFeatureTask((FeatureType.DATA, BAND_NAMES[b])

I could not access the band 's pixels

I am needing to apply a kind of “validations” in the request script, I didn’t get anywhere though. e.g: I need to get the standard deviation of a band using a function and its return should be less than 130, if it’s true, another comparison get done. The problem is: I couldn’t find any way to access the pixels of the band to calculate the standard deviation, the pixels should be an array. Someone have any idea how can I get the all pixels to apply my function? Thank you in advance! 😁

Calculation of Indices

Some of the indices listed in the EO Products page use calculations that do not agree with research literature. E.g. the NDWI is calculated quite differently from most papers I’ve read on it. Even the formula provided by IDB is different: https://www.indexdatabase.de/db/i-single.php?id=60 Can you either rename the indices on the products page or at least provide a link to accepted literature for all the indices calculations please?

Download multiple images

Hi, I have polygons in geopackage format belonging to 20 different fields. According to these polygons, for each field, I want to download RGB tif by clipping all images between June 2022 and August 2022 according to aoi. I want to do this with process api and I couldn’t find an example. I would be very happy if you could help.

Process API-Leaflet Multiple Evalscript

Hi, I am trying to get NDVI and True Color layers on using Process API-leaflet. I’am student and I’ve just a basic knowledge and i am trying to develop sample process api-leaflet code. Sorry in advance. The evalscript I applied for the True Color layer is not working. How can I directly use the layers I created in the dashboard without using evalscript or can I define 2 different evalscripts in my code? Here is my code which works to get NDVI layer correctly. # Sentinel Hub OAuth2 + Process API Leaflet How to use: 1) enter sentinelHubNDVI client ID and secret (go to SH Dashboard -> User settings -> OAuth clients -> "+") 2) open this file in browser *************************/ const CLIENT_ID = "a7b4fba9-cc9c-4fdb-9a15-MASKED"; const CLIENT_SECRET = "Xr-F_M>hTi1O+3xUOEtPcKR-MASKED"; const fromDate = "2020-07-01T00:00:00.000Z"; const toDate = "2020-09-01T00:00:00.000Z"; const dataset = "S2L1C"; const evalscript = `//VERSION=3 //

Low-resolution preview of batch process request from python API

For the last few weeks I have been ordering batch processed Sentinel 2 mosaics via the python API. This process is working really well! I have been using the Request Builder interface to generate low-resolution preview geotiffs of the mosaics. This is very useful for rapidly tuning the date range and maximum cloud cover percentage for different regions. However, it would be much more convenient if I could request those images directly from my python script. Is it possible to order and retrieve the low-resolution preview images like I can from the Request Builder? Perhaps there is a way to write a modified version of my call to SentinelHubRequest to pull the low-resolution version of my full request.

S1 preprocessing parameters differ from manually processed data

Hi,I have a question regarding SH data. I want to download S1 GRDH data from SH for various parcels scattered through Europe (since it would be a huge task to download and preprocess every S1 scene). I’ve used the processing API and custom evalscript, and successfully downloaded the data for an area that I have already preprocessed on my PC. I have noticed that there are some differences in the pixel values between my raster and the one I downloaded.So my question is: what are the exact processing parameters used for S1 preprocessing? Are whole scenes processed beforehand in SH, or are they preprocessed on the fly? Do you use SNAP for preprocessing? Are the output pixel aligned to a standard grid(since I noticed there is a shift)? These are the parameters I used in evalscript:“processing”: {“orthorectify”: “true”,“demInstance”: “COPERNICUS_30”,“backCoeff”: “GAMMA0_TERRAIN”}And one more question, I see in some examples in evalscript that there are two objects (tiff images) listed in res

Artefacts in script-configured indices

I have created a test configuration, based on Python scripts template, containing several indices, either pre-defined by SH or defined by myself. When I execute the WCS request to retrieve those indices over some area in Uganda, in some occasions the resulting images contain unwanted artefacts! Artefact are either: ‘thin diagonal polygons’ of width 200-400 m, aligned with the orbit direction, i.e. direction of scanning (note: I am not discussing here the “seam”, the border-line between the two images, which is just a line); or ‘rectangular polygons’ parallel to the tile geometry in UTM reference system. Therefore I suppose the issue has to be connected with mosaicking. I use mosaic order “Most recent” in all cases. To be on the sure side I have checked also the original satellite images available on the Copernicus SciHub. Neither of the problematic images displays any artefacts or missing data (however, the seam-line is there!) in their original form. Any suggestions how can I avoid th

Possibility to rename the pixel values from out1 --> myowntitle

Getting bounding box by passing specific parameters?

I am a new user of sentinel hub and remote sensing in general… I have some points on the WGS84 and I am interested in getting some bounding boxes in a way such that the points are in the center of the boxes. To be more specific, I would ideally need some code that would get as parameters a specific point, the resolution and the dimensions of the image to be later downloaded. This code should give me a bounding box (whose center is the specific point) to pass to the Process api so that the image downloaded has the resolution and the dimensions specified. Any help, even if it does not exactly answer my question, would be really appreciated !

Sentinel-3 SLSTR BT data
