Hello every one!I would like to know if there is any document up to date that contains information about all the satélites, such as its constellation, the day of launch, orbital parameters and so on. I have looked for it and couldn't find anything, if anyone knows where I can find this info other than in Planet Labs public ephemerides I would really apreciated it. Thank you in advance,Oscar Gamallo
Hi, I'm currently working on estimating chlorophyll-a (chl-a) concentrations in large water bodies using PlanetScope raw data, enhanced with acolite atmospheric correction. However, I've encountered a consistent issue where some scenes exhibit unusual lines or stripes, which I suspect to be noise. This has happened across multiple data sets and seems to disrupt the accuracy of my chl-a concentration readings. Upon reviewing the PlanetScope data documentation (https://developers.planet.com/docs/apis/data/sensors/#the-psbsd-instrument), I understand that each frame consists of eight stripes. I believe these are causing the discrepancies in chl-a concentrations, as values significantly differ from one side of a stripe to the other. This variance is impacting the trustworthiness of my output. Here's an image for reference
Please advise me on how to create a planet story through a flood event. A few months earlier I was able to create a planet story through a flood event, the imagery showed the time-lapse daily, but today I was trying to create a similar story for a different watershed and was unable to find imagery on a daily basis, only one image was available for the whole month.
Hello Everyone! I am writing this post to ask if anyone knows what happens when you try to download imagery from outside of your signed Tier using the Subscription API. E.g. in my case, I have a contract that lets me download imagery for a given polygon from Japan (Tier 1), so if an user mistakenly tries to download data from, let’s say, the US, my subscription creation will fail and throw an error or will I be charged for this?I already read this documentation, however I could not find an explicit reference to this problem. Although, I am guessing I would get a 403 error (Unauthorized). I would appreciate it if someone could answer my question. Thanks in advance!
Hello, I am trying to figure out how to use either the basemaps api or the orders api to download polygon selections of basemaps. So far, I have this code: # Order api stuff for basemaps def download_basemap(self, session, request, download_location, file_prefix): #POST request to get data headers = {'content-type': 'application/json'} response = session.post(self.ORDERS_API_URL, data=json.dumps(request), headers=headers) print(response.json()) #Construct url for getting request status order_id = response.json()['id'] order_url = self.ORDERS_API_URL + '/' + order_id #Check request status, once it's done download data while(True): r = session.get(order_url) response = r.json() state = response['state'] print(state) end_states = ['success', 'failed', 'partial'] if state in end_states: break time.sleep(10) #Download data
Hi,I am finding difficulties in overlaying osmdata over Planet data. Though we reproject them in the same CRS, they don’t seem to overlay perfectly. Has anyone faced the same issue or would anyone please help us in this regard? Thanks.
Hello,Recently I have started using Planet Imagery through a CSDA license for the first time in about a year. Last year we were using PlanetScope Ortho Tiles through the same license. Upon recently browsing Planet Explorer I do not see an option for PlanetScope Ortho Tiles anymore. Are these still available to CSDA users? If so how can we go about accessing them? Thanks,Andrew
Dear Community,I would like to find out how to deal with cloud masking using the UDM2 data from the PlanetScope.I already acquired an image that is cloud-free (from metadata cloud is 0.16). Do I need to do any cloud processing or masking? since this cloud percentage is basically insignificant.Again, I used a shape-file to acquire the image of my location since I want the image to span a period of data range; how do I go about the image mosaicing process?Thank you for the help
I need the updated basemap for my region in Yemen Shabowa Government because the latest update since more than 9 month around Ataq city Were as the other region is updated
REGISTER HEREHow to use Earth Observation data to support communication and action for the environment?Earth Observation allows anyone to engage with verified, real-time information on many environmental issues. Social media gives users such as non-governmental organizations (NGOs) the opportunity to reach many people with their messages. Crises on a global scale can be illustrated in a compelling way using images and time series of affected locations, supported by a wide range of visualization tools that do not require geo-information skills. At the local level, satellite imagery enables accurate quantification of the temporal and spatial extent of environmental change, which can be used as evidence in legal cases. In addition to the freely available imagery from the Sentinel and Landsat satellites, high-resolution commercial imagery from Planet is also available at an affordable price.During this 30-minute live webinar, the presenter Andras Zlinszky will show you:How to search, find
Selecting images that can be viewed in Planet Explorer and adding them to the cart is no longer possible. There is no cart icon available. I am a participant in the Education and Research Program. Have I reached my monthly download limit? Last month, I actually went a touch above my limit a little. I also tried to download a past order again to see if the order itself could be placed. However, assets are not configured.
Hi, I’ve submitted an order via the planet explorer and got an email with the download link.However, the download always failed.the zip file has 99 images with a size of ~40GBis it too big to download? If so, if it possible to ask you to divide the big zip file into small ones?PS, I can download these images via api, will I be charged again? best,Haiyan
'm relatively new to the Planet API, having engaged with it for just over a week. Following the GEE-Integration guide, I've successfully exported data to Google Earth Engine. Now, I'm working on cloud masking for a cloud-free composite using the asset type "ortho_analytic_4b_sr" and the scene "PSScene". I have around 122 images in the collection. I've come across "udm2" for cloud masking but I'm uncertain about its implementation. Also, once the requirements are met, could you guide me on downloading it? I'm unclear on parameters such as scale and maxPixel; my attempt to download a single image seemed off from the expected result.Appreciate your assistance.

Why do my orders for Planet imagery using the API remain in a 'running' state but eventually change to 'failed' status when I attempt to download them using Postman, and how can I resolve this issue?
I am new to the platform and can’t find any reference to night-time imagery as I’d like to do a classification of illuminated areas. I can understand not having that imagery stored regularly as it is less applicable to most people. However, could this be tasked, can I find examples of this? Any guidance would be appreciated!
