Tanager Hyperspectral Satellite – Data Access and Overpass Schedule

Hello Planet Labs Community,I’m a graduate researcher working on a hyperspectral remote sensing project, and I’ve noticed that there doesn’t seem to be access to Tanager hyperspectral data through the Planet Explorer platform. I’d appreciate clarification on: Whether Tanager data is currently available for research use How to access it (if available) Where to find overpass or acquisition schedules for this satellite Any guidance or resources would be greatly appreciated.Thank you!Muhammad

NDVI discrepancy across AWS, GEE, and Sentinel Hub – Same Sentinel-2 Scene

Hi everyone,I'm conducting a crop monitoring project in southeastern Turkey and comparing NDVI values across three platforms (AWS, GEE, and Sentinel Hub) using the exact same Sentinel-2 tiles and date.During this process, I observed consistent NDVI differences across platforms, even when using the same data product level (e.g., L1C). Scene MetadataDate: 24 August 2024 Tiles: 37SDA, 37SDB, 37SEA, 37SEB AOI: Same polygon used on all platforms Bands: B04 (Red) & B08 (NIR), scaled to [0–1] as needed NDVI Comparison (Tile 37SDA Example) Platform Product NDVI Mean NDVI Min NDVI Max AWS L1C 0.5206 0.4238 0.5582 GEE L1C 0.52198 0.4475 0.5582 GEE L2A 0.6085 0.5173 0.6458 Sentinel Hub L1C (EO Browser) 0.74 0.56 0.80 Sentinel Hub L2A (EO Browser) 0.85 0.61 0.93

Optimising Number of Samples in Processing API

Dear Planet/Sentinel-Hub Community,we are trying to optimise our requests to the Sentinelhub processing API. ContextWe are working in the climate-action domain and see this as a way to reduce our emissions (and PU cost). We have already implemented some optimisations like the output format, the output resolution and improving caching. In this context we also opened two issues in the sentinlhub-py repository #560 and #561.GoalFor any arbitrary area, we want to have at least one valid sample per pixel per month but as little samples as possible overall.ProblemOur analyses are temporally and geographically unbound. We therefore use multiple timestamps to assert data availability and robustness. One of the last optimisation potentials we have identified would be the reduction in the number of samples that are fed into our eval-script (i.e. sharpening the filter criteria, similar to the examples on "select one image per month"). Here we were unsuccessful due to the limitations of the API (o

✨ New Release: Planet SDK for Python v3.0 ✨News

Planet has released version 3 of the Planet SDK for Python. If you are an active developer using the SDK, you should upgrade to the latest version.What’s NewVersion 3.0 includes the following major features:OAuth authentication #1134. In version 3 of the SDK, when you authenticate with a username and password, you will be directed to complete your sign-in through an OAuth login portal in your browser. Username and password authentication will no longer be allowed without completing the OAuth login flow. For automated scripts, API key authentication is still supported. Support for the Basemaps API #1142. You can list mosaics that you have access to and download Basemaps quads.Migration and SupportVersion 3.0 is a more incremental release than 2.x was over 1.x. For migration details, see the Upgrade from Version 2 to Version 3 migration guide.Packages are available on Planet PyPi for download. Source code is available on GitHub.

Sentiel Hub API Deprecated?

Hi, I am trying to understand if Sentiel Hub API is deprecated or not, but get mixed responses online. Also, if it is, what is the alternative? My goal is to get NDVI and do some other calculations of agriculture related parameters.

Planet Fusion and SentinelHub Catalog API

Hello, I am downloading Planet Fusion data for a project through a BYOC Collection on SentinelHub. The plan is to have a STAC catalog on my side to archive the data for future use. When I query the Catalog API I get STAC items that have an empty object in the assets field. Is this normal? Is there a way to get this information or at least a template of the whole STAC item?

Drop in revisit rate in 2022 and beyond?

I am working on a project based in Alaska, and put together a script using the API to see how many image-days per month are available in my study region. However, I noticed a really weird trend in 2022 and beyond, where the average daily images drops by almost 50%. What is going on here? I have attached a graph showing data availability with a Planet cloud threshold of 25% image cloud cover (ignore the grey trend line behind, that is unrelated to planet data.)What is going on here with the drop in data coverage?

Receiving High Cloud Cover (30–70%) in Planet Imagery via Sentinel Hub – How to Filter Cloud-Free Scenes?

Hi Planet Support,We are using Planet imagery integrated via Sentinel Hub under the Area Under Management (AUM) subscription model. While we expected imagery to be filtered for quality, we are regularly receiving scenes with 30% to 70% cloud cover, which affects our ability to extract usable insights for crop monitoring.Could you help clarify: Does Planet imagery delivered through Sentinel Hub include unfiltered/cloudy scenes by default, or is there internal cloud filtering applied in AUM subscriptions? What are the best practices or parameters we can use (in Sentinel Hub or Planet APIs) to ensure we only receive cloud-free or low-cloud scenes (e.g., <10%)? Is there any difference in cloud-filter behavior between PlanetScope and SkySat products in this context? We are building precision agriculture products and need clean, high-quality imagery for daily to weekly analysis.Any guidance or examples would be appreciated.

Best workflow for inspecting 14,000 plots (Costa Rica, 4 dates) with 5 interpreters in QGIS/Collect Earth — tile streaming or Visual Quad download?

Hi everyone,Project snapshot AOI: Costa Rica (~51,000 km²) Plots: 14,000 (1 ha each) Dates to inspect: Jan-2021, Jan-2022, Jan-2023, Jan-2024 Tools: Collect Earth Desktop + QGIS Team: 5 interpreters working in parallel Current plan: Insights Platform – Basic (70 k PU/month, 500 PU/min) Issue With Visual-tile streaming (1 PU/tile) we exhausted the quota in a week. Usage dashboard has shown 0 PU and only 9 requests for several days (possible burst-triggered block). We need to restart work and pick a workflow that won’t hit the limit again. Options I’m considering Stay with streaming but upgrade temporarily (Enterprise S or L) and add a caching proxy. Download all Visual Quads (Basemap Global) and serve them via MapProxy/GeoServer; work offline. Use NICFI quads (1,500 PU/quad) only in forest zones and Basemap Global elsewhere. Push quads to GEE and let interpreters view via Earth Engine. Key questions What workflow do others use when multiple analysts review large visu
