Hi Planet’ers ! I have a quick question concerning mosaics in ArcGIS Pro that I’m trying to build with planet data. So, I have 3 beautiful separated planet images Here is how they look all togetherNow I want to mosaic them But the mosaic gives me something like this, not a harmonized image… and the colors are very distorted...I followed the Planet ArcGIS guide https://university.planet.com/planet-integrations-arcgis-pro-workflow/1244865 and used Max it didnt work, then I used Blend, then Last, same with every single Operation , nothing worked….Hope someone can help me ! (or even the support team :) thanks !)Kind regards from Belgium !

Only three bands valid for Planet Basemaps "global_monthly_yyyy_mm_mosaic"

Hi,I have a problem with the NIR band when I used the product "global_monthly_yyyy_mm_mosaic". It seems like it has four bands (RGB+NIR) band but the NIR contains only the value 255. I am not sure this is a technical issue or this product only has three bands available.Thanks for your help!

Non consistent surface reflectance values

Hello everyone, I am using PlanetScope Scene images already corrected in surface reflectance (Dove Classic) to assess the temporal changes of the vegetation cover on a specific site. As the site is about 30 km long, I need to use several tiles to cover the whole area. I have recently noticed that the reflectance values of the pixels of two overlapping images are quite different (even if the images were taken by the same satelitte, at the same time).Do somebody know why do I oberve this ? If yes, do somebody know how can I solve and obtain consistant surface reflectance values between overlapping tiles ? I thank you in advance for your answers, Léo

Missing metadata and problems with the tool Apparent Reflectance

Hello,I'm a college student and not very proficient in using ArcGis Pro and Planet Imagery.I would need advice on the Apparent Reflectance tool. I'm working with images from the PlanetScope satellite and I don't know where the problem is, but I don't see the metadata of the images. It's rejecting my data format. So I opened the metadata in a normal browser. To create I need Radiance Gain and Radinace Bias for each band. I'm not sure, but isn't it Radiometric Scale Factor and Reflectance Coefficient in the source current? Next I need the Sun Elevation, so I assume that is the same as the Illumination Elevation Angle? And I also know the Scale Factor and Offset, because it results from the number of bits in the image.So I tried to use these values to create. But it told me that the Acquisition Date is missing, probably because I don't have the metadata uploaded there. So now I don't know what to do with it, because I have nowhere to write the Acquisition Date.I will be grateful for any a

Question with azimuth angle of PlaneScope data

Hello,I just want to know the satellite azimuth information for PS2.SD L1B images which I downloaded.I found that there are two types of metadata: GeoJSON metadata and General XML metadata.And the definitions of the "satellite_azimuth" in GeoJSON metadata and "azimuthAngle" in General XML metadata are quite different. In case of "azimuthAngle" in General XML metadata, "azimuthAngle" means "The angle from true north at the image to the scan (line) direction at image center, in clockwise positive degrees" from the PLANETSCOPE PRODUCT SPECIFICATIONS document.The "orbitDirection" of my PS2.SD L1B image is "DESCENDING" so I thought the scan (line) direction must be equal to a direction like following figure in consideration of how PS2.SD image composite were made.However, I found that "azimuthAngle" is 1.203555e+01 in General XML metadata and it doesn't make sense because I think “azimuthAngle” must be at least over 90º.So, I want to know what I missed...Thanks.

My last Saturday post regarding issue with scene donwload calcualtion

Hi all,In my last Saturday post I said I couldn’t understand why in a day my quota moved from 12% to 70% when effectively I have downloaded only 1 image. I have discovered later in the evening the reason.Because I was learning and understanding how to build a request block, in the last modification I have forgot to insert the “tools” block sand this mean I have downloaded 2 full strips of images.At the same time I have discovered that once the request is processed, the images can be downloaded already from the web page ( another thing I learned).I have 2 questions to ask:is the bundle information always required when creating an order? when I have multiple images in the same days and added to create a composed one, the km2 are calculated for single images or the composite one? This will help me to figure it out how many images i can use per vegetative cycle per year - I have to cover 5 yearsThanks and apologies if my previous message made some messRegards,Davide

Planetary Variables: Soil Water Content Validation WhitepaperBlog

Attached is a whitepaper that covers both a spatial and temporal validation of Planet’s latest Soil Water Content product.The paper, which is partly based on Planet’s own field measurements, does a great job explaining why the validation of soil water content is so challenging. Other interesting topics covered are the number of in-situ measurements you need to get an equivalent of 1 Soil Water Content pixel (spoiler alert, this is 7!) within the same uncertainty and results of many temporal validations showing Pearson correlations up to 0.9.Please reach out to https://www.planet.com/contact-sales/ with any questions!

Using Planet data to map coral reefs in Buccoo Reef, Tobago

Hello everyone, my team and I are utilizing Planet data for reef assessment in Buccoo Reef, Tobago. Reefs in the Caribbean region have suffered a substantial loss of 60% - 80% since 1970s and Tobago have been severely affected. We hope to use our results to implement monitoring and management strategies for the Buccoo Reef. Here is a similar paper that I’ve found using Planet Dove Satellites for reef assessment: https://zslpublications.onlinelibrary.wiley.com/doi/full/10.1002/rse2.42 Excited to post our results soon!

What techniques are you using to co-register your Planet imagery?

Hi Planet Users!I wanted to start a conversation around co-registration and learn about the ways you are doing it. What techniques are you using and what software or platforms are you using to implement it? Planet’s API’s do have a co-registration tool-chain that can be used on a API order - see documentation here, however, we know that there are other workflows that might work best for you. Looking forward to hearing how you co-register Planet imagery!

Searching Images over a large multi-polygon over multiple years

This question was originally asked June 15, 2022 13:55 by user Amninder Singh. Hi, I am new to using Planet API. I am trying to search for imagery over a multipolygon GeoJSON (which consists of ~10,000 small polygons across the United States) from 2019 to 2021. My goal is to deliver this imagery to the Google Earth Engine for analysis. Here is a snippet of code that I am using with DataAPI for quick search:item_type = "PSScene4Band"# API request objectsearch_request = { "item_types": [item_type], "filter": combined_filter}# POST requestsearch_result = requests.post( 'https://api.planet.com/data/v1/quick-search', auth=HTTPBasicAuth(PLANET_API_KEY, ''), json=search_request)ids = [f["id"] for f in search_result.json()["features"]]The above section of code will not display more than 250 ids (I think this is the default). Any way I can obtain all the resulting 'ids'?Next, I am creating a request using the Orders API using the `ids`. request = { "name":"cliptryGEE", "product

What packages do you use for data processing?

What software/packages do people use to access/use/process/visualize Planet data?I have done most of my processing either in QGIS, or in python, where I have found rioxarray to be a very useful python package for just about all of the above, but I am still learning all the packages out there that could be useful.What other python packages do you use and why? I am also interested in knowing if people use R (and if so, which libraries are most helpful). Does anybody use Google Earth Engine? Any tips?I recently learned about the RSAGA library, but don’t know anything about it...does this work with planet data?(I also saw this post on datacubes, but am really interested in seeing what people are using for planet data at all, whether it requires large time-series datasets or not!)

I understand that in Data API, I can use date range, cloud coverage to filter the image.I am wondering is it possible to filter images using "Radiometry" as shown below, e.g., I can set the parameter to "surface reflectance". If I cannot set the parameter, what kind of images do I download? Are they the type of "surface reflectance"? Thanks
