WMS/WMTS on ArcGIS Online

Is anybody else having any issues with adding WMS/WMTS services to ArcGIS Online? I am able to add a WMS service and it appears in the content but no imagery is shown. I have no issue with adding these WMS/WMTS to QGis, ArcPro, or ArcGIS Portal running on Azure. Thanks, Christian

How to remove cloud cover from RapidEye?

Hi, Hope you are doing well. I have downloaded nearly 50 tiles of the wet tropical rainforest of Australia, and a few tiles have severe cloud cover even after applying the filter function of Planet Explorer.  So, how can I remove those clouds? Unfortunately, there are no reference images available without Cloud for those locations in near times (2019). I am using QGIS. Any suggestions in this matter are highly appreciated. Kind regards,Shawkat

How to “remove” the clouds in an NDVI image AND return as 1 band

I am trying to download NDVI as 1 band with a Cloud mask. Esssentially I am trying to combine these two scripts and need some assistance. Cloud mask //VERSION=3 function setup() { return { input: ["B02", "B03", "B04", "CLM"], output: { bands: 1 } } } function evaluatePixel(sample) { if (sample.CLM == 1) { return [0.75 + sample.B04, sample.B03, sample.B02] } return [ 2.5*sample.B04, 2.5*sample.B03, 2.5*sample.B02]; } 1 band NDVI //VERSION=3 function setup() { return { input: ["B08", "B04"], output: { bands: 1 } }; } function evaluatePixel(sample) { var ndvi = (sample.B08 - sample.B04) / (sample.B08 + sample.B04); return [ndvi]; } It does not have to be these two scripts specifically, but if anyone has any suggestions on how to effectively combine these two i’d appreciate it. Thank you!

How to get evalscript that calculates NDVI for each available satellite repectively

in the project i am working on, i should calculate the ndvi for all satellite missions. i know how to structure and build the request, but it seems the evalscript through which the ndvi is calculated differs according to the selected satellite mission. my question is, can i refer to EO Browser and copy the evalscript from it? i mean, one can check the evalscript used in the latterly mentioned link, can i simply copy the evalscript from it and paste it in my code?! is that possible

Download multiple images causes rate limit exception

I am using process API [Preformatted text](https://services.sentinel-hub.com/api/v1/process) but I have to fetch the data for 500 places in less than 30 seconds. So according to my knowledge, SentinalHub doesn’t support multiple (png/jpeg) images in 1 request. So we have to loop the coordinates and hit the API for each image. Problem: The issue is API fails and returns the Rate Limit exception. Is there any way through which we can hit 500 requests in less than 30 sec, or hit a simple call and get 500 images? Our request payload is below: const input = { input: { bounds: { properties: { crs: "http://www.opengis.net/def/crs/OGC/1.3/CRS84", }, geometry: { type: "Polygon", coordinates: [coordinates], }, }, data: [ { type: "S2L2A", dataFilter: { timeRange, mosaickingOrder: "leastCC", }, }, ], }, output: { width: w, height: basSize, responses: [ {

Cloud pixel percentage

I’m trying to create function to return cloud pixel percentage based on SCL Sentinel 2 L2A following these functions: //VERSION=3 function setup() { return { input: ["B02", "B03", "B04", "SCL"], output: { bands: 1 } }; } function calcCloudPercentage(SCL) { var cloudCount = 0; var totalPixels = SCL.length; for (var i = 0; i < totalPixels; i++) { if (SCL[i] === 3 || SCL[i] === 8 || SCL[i] === 9 || SCL[i] === 10) { cloudCount++; } } return cloudCount / totalPixels * 100; } function evaluatePixel(sample) { var cloudPercentage = calcCloudPercentage(sample.SCL); return [cloudPercentage]; } However, the functions always return “null”. Anyone could help to understand why this return?

Accessing Sentinel data for lakes

Hi, While trying to explore the EO browser, I understood that there are images related to Chlorophyll index values (Ullysis Water Quality Viewer). Is there a possibility that I can directly access the raw data associated to the RGB images, directly from Sentinel-2. How do we download them into CSV format? We need it for location Devils Lake, North Dakota from the years 2016-2022 (May - Nov) or atleast one year or summer. Thanks,

Statistical API: Exceeding width and length limits with goal of calculating tile statistics

Hi team, I want to calculate the percentage of clouds in a tile. However, I’ve encountered that the tile’s width exceeds the allowed 2,500 range. Would the most effective approach be to split the polygons into smaller chunks and process iteratively, or is there a more efficient workaround anyone can suggest on the tile level? I’m keen to maintain accuracy but also want to avoid excessive overhead if possible. Thanks in advance for any insights!

Techniques to get high resolution images of given coordinates through EO Browser or Python package

Hello everyone, I am tackling a deep learning project and I need satellite images such as this one. Given I have a set of known coordinates, how and where can I get images of this resolution? Trying through EO Browser the best I get is with bilinear/bicubic upsampling and it is still blurry and not usable. The same with sentinelhub-py. Any advice on improving resolution of Sentinel products will be most welcome. My last resort will be super-resolution though I don’t think I will get much with it. Please note that I am not looking for commercial products (Pleiades etc).

I am downloading Sentinel-2 L2 products from EObrowser, but I cannot download the data from 2017 to 2018. When I try to download an image of one of the 2017-2018 scenes, I get an error message like the one in the sentences below and cannot download it.

Creating a Custom Grid on a Folium Map

I am quite new to python and I need to create a custom grid with a specific spacing on a Folium map for a particular district. I have added the Polygon of district boundary on the folium map. The grid spacing should be set to 7 km in the x-direction and 5.5 km in the y-direction. I have written the following code but I am stuck at that. Is there any library for creating the grids? Can anyone guide me how to do it? Any help would be appreciated. import folium from shapely.geometry import Polygon import geopandas as gpd # District boundary polygon district_polygon # Create a GeoDataFrame with the polygon as the geometry column district_gdf = gpd.GeoDataFrame(geometry=[district_polygon]) # Set the CRS for the entire GeoDataFrame district_gdf.crs = {'init': 'epsg:4326'} # Defining the size of the grid cells in decimal degrees grid_size_lat = 0.063 # roughly 7km at the equator grid_size_lon = 0.0505 # roughly 5.5km at the

EO Browser Network Error' downloading Hi-Res'

Hi All, I have created a cloudless mosaic in EO Browser using the cloudless mosaic custom script. However when I try to download this in Hi-Res I get the following error. “An error has occured while fetching some of the images: Network Error”. Reducing the size/resolution of the area being downloaded resolves the issue, but to get the resolution I’m after (approximate 14,000px wide image) would require a large number of downloads and then stitching them together. The “How to create your own Cloudless Mosaic in less than an hour” tutorial looks like what I need, but using “Batch” mode seems to require a 400 euro/month plan. I would be happy to pay to download the image, but this is a one off personal project so 400 euro is a bit out of my budget. Is there another or better way to do this? Any help would be much appreciated. Regards, Steve

Question about downloading images with API

Hi! Im using the API for download a bunch of images and i have a trial account. Let’s say that i have a 10.000 lines excel and i have to request those lines and download with the API that quantity of images…can i do that with the trial account or do i have to pay for a package? Because when i go for the line 140, the script send me this error message:SHRateLimitWarning: Download rate limit hit ** warnings.warn(‘Download rate limit hit’, category=SHRateLimitWarning)** I don’t understand the PU usage and that. What do i need to do for download that entire excel? thanks!

Difference between Sentinel Playground and EO Browser

Hello, I wonder if someone could help me understand this. What is the difference between Sentinel Playground and EO Browser? Specifically, I am trying to understand why one image is showing cloud cover that the other does not show. Is it that the EO Browser only shows imagery taken for a specific day, whereas the Playground is accumulated data over time? Thanks in advance, Ryan

How can I get the exact date the image was captured?

Hi, I’m using the Rest API and retrieving image from this endpoint: https://services.sentinel-hub.com/api/v1/process Here’s my request example: url = "https://services.sentinel-hub.com/api/v1/process" headers = { 'Accept': '*/*', 'Content-Type': 'application/json', 'Authorization': f'Bearer {token["access_token"]}', 'Origin': 'https://apps.sentinel-hub.com', 'Connection': 'keep-alive', 'TE': 'Trailers' } res = requests.request("POST", url, headers=headers, data = json.dumps(payload), timeout=10) What I get in the res.content is an image but I’m also interested in the date it was captured. Is there any way I can get the date it was captured?

Convert filename on download

Hi, I’ve just started trialling sentinel hub, with the objective of being able to download a time-series of imager for a specific AOI, less than 10km2. Ideally, it would be best to store the extracted data locally, with an appropriate filename, with the sensor name and acquisition date in the GoeTiff filename. However, when I use the SentinelHubCatalog API and the standard SentinelHubRequest API together, I am only able to pull imagery down with the request format (folder with random request ID, and then the standard ‘request.json’ and ‘response.tif’ files). Is there anyway to rename the file so that it can be identified, otherwise you have to use the request.json each time? Alternatively, am I using the wrong tool? Is there a way of capturing a time-series for a small AOI? Below is my current script, in which I search using Catalog, and then use Request to collect 3 images (I have added a download folder path extracting the date from the timestamp): import python libraries import os
