NDWI add DataMask

Hey, I am trying to add dataMask to NDWI index from custom scripts, but the whole screen is blue. I’m adding the code below. var colorRamp1 = [ [0, 0xFFFFFF], [1, 0x008000] ]; var colorRamp2 = [ [0, 0xFFFFFF], [1, 0x0000CC] ]; let viz1 = new ColorRampVisualizer(colorRamp1); let viz2 = new ColorRampVisualizer(colorRamp2); function evaluatePixel(samples) { var val = index(samples.B03, samples.B08, samples.dataMask); val.push(samples.dataMask); if (val < -0) { return viz1.process(-val); } else { return viz2.process(Math.sqrt(Math.sqrt(val))); } } function setup() { return { input: [{ bands: [ "B03", "B08", "dataMask" ] }], output: { bands: 4 } } }

Mosiac Imagery Resolution

Good afternoon! I stumbled upon the s3://sentinel-s2-l2a-mosaic-120/ bucket have been enjoying hitting it up for country-wide imagery. I was curious though, the website that let’s you explore Sentinel’s cloudless imagery goes up to 10m resolution. Is that available at a different endpoint on AWS, or is 120m as high as is publicly available? Likewise, if there’s a better way to fetch 10m cloudless data, all ears!

Send filtering data to custom Script from client

I have a NVDI WMS layer configured to show NDVI index, and I need to let the user choose the color ramp. Is there a way to send parameters from the client and get then inside the evaluatePixel function? According to reference this is the signature of the method, but I can’t find an example that uses inputMetadata or customData or a reference about their content. function evaluatePixel(samples, scene, inputMetadata, customData, outputMetadata) { } Thank you

Raw metadata.xml extraction using Catalop API

Hello, I am looking to extract the metadata.xml for the Landsat 8-9 products as I need to extract the sun elevation angle and relative sun earth distance for for some calculations. As per some reading, I read that it can be extracted via catalog API or WFS request, but sadly no help is available regarding it script. Can you please help in extracting that metadata.xml?

Sentinel-1 orbits impacting data

Hi!A few months ago, I asked about some specifics about Sentinel-1 orbits (here). Among those questions, we were wondering if data should be separated by orbit or not, as the bibliography said that orbit in non-plane topography impacts data.We observed that in several cases of ours, for example as below:We can see that ascending and descending VV/VH are sometimes quite different, particularly VV (for example around half of february). There is another example in the topic I linked earlier.A descending and an ascending pattern can be seen in both bands, i.e. VV and VH. For instance, descending data has one spike in late january and in mi-february, but is lower than ascending variables starting around may. So at least it seems logical from this pov.When we call for both orbits without separating them, we obtain the following graphics:You can see that the signal with both orbits seems unstable and rather spiky as expected (for example around mid-february, once again).We got the data using

Origin of dataCoveragePercentage

Hi,I was wondering where the “dataCoveragePercentage” within “tileInfo.json” comes from, because I cannot find it in the metadata xml-files. Did you compute it yourself or did you read it from some file?Thanks in advance

Thank you & best regards!

Why is there a variation in imagery?

I was looking at the imagery for a region in India, for 5th December, however I see variation in different tiles. Is it because of different acquisition times or some problem at the processing end on Sentinel Hub ?

Calculation of NDVI

Hi,I am doing some comparison between NDVI from EO browser platform and from calculation offline starting from the band rasters downloaded by https://scihub.copernicus.eu/dhus/#/home (both with L2A level)I have tried also the custom panel in EO platform with the instructions of this post (NDVI values from SentinelHub different from the ones calculates in Qgis) among others, but I keep getting different values (the differences are not negligible), in particolar higher values in EO browser with respect to the offline calculation.Could you help me please?Thanks in advance

Tile_splitter for Landsat-8

Hi, While trying to use the tile_splitter function in sentinelhub.py, it cannot produce the correct tiles and I don´t know why. For Sentinel2-L1C collection it works just fine but not for any Landsat-8 collection. Has anyone else faced this problem?

Resampling with Sentinel-hub py

Hello,Is there any built-in function to resample saptial resolution?To be more specifically,i’m interested in resampling Landsat 8 to Sentinel -2 spatial resolution.As I haven’t found any “direct” way to do that, I thought maybe to use the data fusion tool and to return empty bands for sentinel2 as I want only landsat 8 , but not sure it can work and also wanted to know if there is any recommennded methodology.Best

Problems with NDVI value from PlanetScope

Hi all, I’m having some problems with the NDVI value of some images I just downloaded. I transformed with QGIS the Tiff file downloaded from Sentinel Hub in a polygon. But here the value of NDVI are between 0.6 and 1 which is too high for this time of the season. Is there a specific process I should use to download this images/transform them in a polygon? Here you can see the option I am using at the moment to download the Images. The tool I use to generate the polygon is “Raster pixels to polygons”. Thanks for your help.

Authentication problem

I have an account, which have been stopped for a period, where I didn’t used it. I use the Sentinel Plugin in Qgis. Now I have payed again and I have created an new OAuth client, due to login failure but it still doesn’t work!? To check if I create the OAuth client correctly, I made a new Sign Up with a random gmail, and got 30 days trial. That works! I don’t understand??? Hope someone can help!

SciHub links not working

I am not able to access most of the SciHub links when trying to download a full Sentinel Tile through the EO Browser. For example: https://scihub.copernicus.eu/dhus/odata/v1/Products(‘27c1c8c2-47a9-4e45-837c-9746b67b9731’)/$value The same Tile from yesterday has a working SciHub link:https://scihub.copernicus.eu/dhus/odata/v1/Products(‘c3d2bcde-d7cd-4e47-8561-46cf0d1972e4’)/$value What is the origin of this problem? Is there a better way of downloading the full tile?

Index value count

Hi All, I am busy investigating how to monitor water bodies in using Sentinel Hub. We use Sentinel Hub in our portal to display images and graphs. At the moment Sentinel hub sends us the min, max, mean and std deviation. Is there a way to have a count on the number of pixels above a certian value. Thank you

Best way to query for tiles acquired in a date/time range?

I’ve been looking through both the python and REST APIs for a way to query for a list of all tiles that were acquired during a particular date/time range. So far I’ve only found out how to do it the other way around (i.e. query the available dates for a specified tile). I’m hoping there is some way to avoid the brute force approach of getting the dates of all tiles and filtering for the ones in the window. If it helps, the purpose of the activity is basically one step in a bigger process to figure out which tiles have recently become available and I need to process. Any suggestions or pointers would be greatly appreciated.

Top-Up PlanetScope Quotas

Dear SHub team,I’m trying to understand a bit better the procedure of PlanetScope data. I purchased 100 hectares for Tier 2 and I would like to buy more NEW hectares in the same Tier. Since the Planet Top-up quota says that “it only applies with consecutive purchases on the same AOI of already subscribed areas”.Should I buy a new packet of 100 hectares? Should I follow the Top-Up quota process? If I buy a new packet of 100 hectares in Tier2, does the period of one year start when I buy them since I’m paying again 150€? Or I will pay the proportional time until the 26th of October (starting time of my first order)? I’m asking this because if I want to buy a new packet of 100 ha I’m billed 150€ and not the price of the remaining period.Thank you in advance!Reminder: my objective is to add new hectares for PlanetScopes images.Kind regards

Possibility to fuse different sensor's data?

Is it possible to combine, e.g. Sentinel-1 GRD with Sentinel-2 L2A data inside scripts? If not, is it something in the future roadmap?

Burned area detection script

Hi - the BAD script (pun not intended) is highlighting areas over the waters of a marsh/lake for a specific timeframe. Part of it I know as being related to real fires, but I see the results as recurrent over months. How likely is it that they’re false positives? I can provide the specifics but would prefer to do so in private if possible (it’s related to research I’ll publish soon). Pinging Monja Šebela who I see is the script’s author. Thanks!

V3 Transition for Sentinel 2 L2A level

Hello everyone! Today I found that all my layers configured in v1 and v2 have converted to v3. Any layers that used Sentinel 2 L2A level of processing become unable for visualization. Does anybody know how to configure Sentinel 2 L2A data? Below is the non-working script after automatic conversion. let minVal = 0.0; let maxVal = 0.4; let viz = new DefaultVisualizer(minVal, maxVal); function evaluatePixel(samples) { let val = [samples.B04, samples.B03, samples.B01]; val = viz.processList(val); val.push(samples.dataMask); return val; } function setup() { return { input: [{ bands: [ “B01”, “B03”, “B04”, “dataMask” ] }], output: { bands: 4 } } }
