how to purchase imagery with low revisit rate but wide range (probably global)

I am working on a geopolitical science project on a weekly basis, how to get the PlanetScope global image within 30 days but with a low revisit rate? I've noticed the MONITORING PLAN, but a high revisit rate doesn't fit my needs. Thank you!

Issue with PlanetScope product type 'Harmonized'

Hi, I’m having issues with the ‘harmonized’ PlanetScope data products.I have been downloading several such scenes and after saving the extracted data folders on disk, the products seem not be the harmonized versions of the scenes. I posted a related question in the forum some months ago but I realize that, from my part I correctly choose the data product to be ‘harmonized’ (please see attachment temp_screenshot.jpg) while ordering. Nowhere in the downloaded files (.tif extension, manifest json file) is there an indication of the product being harmonized, it looks like an ordinary surface reflectance composite scene.For reasons I don’t understand, on the only 2 instances where I received properly annotated ‘harmonized’ products, the extracted folder had a different structure (attachment temp_screenshot_2.jpg). Usually each downloaded product gets extracted in a single folder that contains the ‘manifest’ and ‘catalog’ files.I would really appreciate some assistance/ clarifications here.

Resources and Q&A - Agile EO: Aircraft Detection at Planetary Scale

In March’s Agile EO episode, we introduced Aircraft Detection—a new offering that provides near-daily monitoring of thousands of airfields globally, enabling trends and anomalies to be spotted. Watch the webinar on-demand. Below are common questions, and questions that we weren’t able to get to during the live event. Our hosts Justin Davis, Sr. Product Manager - Applied Machine Learning, and Adam Van Etten, Principal Data Scientist, have provided answers, plus resources to learn more. QuestionsQuestion: Can you track aircraft in flight? Answer: We can’t say for sure that a given aircraft is the same aircraft from one day to the next, BUT we can track how many aircraft are present at a given airfield each day AND whether the aircraft present are in the same positions as they were before. This can help indicate activity at a given airport/airfield and highlight anomalous behavior. Question: How big of an airplane can you detect?Answer: In our experimentation, we found performance for ai

Scaling and indices for bands for planet images

Hi,I am very new to remote sensing. I got raw images from planet scope for my area of interest through QGIS plugi. however before I calculate NDVI for my area. I need to normalised or scale the bands. I am using this formula lower_percentile = 30upper_percentile = 70y1=float(0.2)y2=float(0.5)def scale(band): # scale values for display purposes band = band.astype('float64') x1 = np.log10(float(np.percentile(band[band!=0], lower_percentile))) x2 = np.log10(float(np.percentile(band[band!=0], upper_percentile))) band[band==0]=np.nan band = np.log10(band) def equations(p): a, b = p return (np.log(a)-x1*b-np.log((1-y1)/y1), np.log(a)-x2*b-np.log((1-y2)/y2)) a,b = fsolve(equations, (1, 1)) band=1/(1+a*np.exp(-b*band)) return band. Can somebody please tell why could be different method for scaling and is there any paper which can recommend for scaling the planet images?

Preparing Imagery for Time-Series Analysis

I am attempting to prepare PlanetScope imagery for a time-series analysis. I have read a bit about transforming imagery into Analysis-Ready Data (ARD), so I am aware of the general steps in the process. This is the high-level workflow I have come up with so far:masking --> normalization --> compositing --> co-registration However, I am not sure how to implement these steps. Does anyone have any resources that describe how to prepare imagery for time-series analysis in as much detail as possible? Some other details:I am using 8-band imagery from SuperDove sensors I have downloaded imagery as analytic surface reflectance at this point (but am open to other formats) I am using Python to acquire and process this imagery.Thanks for any help you can provide.

RGB reflectance ranges for proper RGB layer display on QGIS

I am having trouble in getting a clear display of a true color composite (TCI) of a harvested farm in north of India in QGIS. I am using Planetscope image of 2024 from the 8-band Superdove collection. This is a 2.5 acre farm. The TCI content is getting obscured by rainbow effect (‘Unclear.png’). The band ranges and other symbology details are given in ‘Unclear_specs.png’). I have attached a screenshot of the metadata of this farm for reference (‘Unclear_metadata.png’). What band value ranges or other parameters should I edit to see a clearer image?FYR, I have attached screenshots in the three categories for a larger farm (14 acres) that is harvested in one plot and tilled in other plots: Clear_14ac.png, Clear_14ac_specs.png, Clear_14ac_metadata.png. This farm has a very clear view. The clear confidence percent for this image is 95 as compared to the unclear farm (85) but that should not produce such a drastic difference in clarity given the clear percent in both images is 100.Please he

Prior to the expiration of Planet’s previous CSDA contract with NASA I had been using the Planet API to download Planet SuperDove imagery straight into Google Earth Engine. When the contract expired, I lost access to imagery via the API but am hoping that is now reinstated. Have any changes been made to Planet access via the API with the new CSDA contract? Specifically, I’m curious about limits on 8-band SuperDove imagery downloads, as my project requires a lot.

How is Scene Download usage calculated?

I downloaded PSScenes for two locations yesterday. One location’s extent was 0.003 km2, the other was similar. I downloaded 9 daily scenes for one location and 4 for the other. I got 8 bands for each day. My thinking, the total area for one location is 8 (bands) X 9 (days) X 0.003 km2 = 0.216 km2 for one location. The other location is about half that, since I had half as many days. However, my account dashboard says that I’ve used 1300 km2 this month, even though those were the only downloads I’ve done this month. Can someone clarify this for me, please?

Albedo estimation from Visible and NIR

Hello Everyone!I am a beginner, and I am trying to explore the possibility of estimating surface albedo using PlanetScope data. Since there are several established relationships between the visible and NIR bands from Landsat 8 and Sentinel-2, I was wondering if anyone has explored the use of PlanetScope data for surface albedo estimation.Can we use the visible and NIR bands from PlanetScope data to estimate surface albedo?I would really appreciate any help or insights.

PlanetScope VIs calculation

Hello I’m a beginner in GIS and have a few questions about calculating vegetation indices (VIs). Here are the details of my process: I have PlanetScope images (4 bands, 3B_AnalyticMS_SR). I successfully calculated NDVI, and the result was as expected, ranging from -1 to +1. However, when I tried to calculate EVI using this formula (2.5 * (NIR - Red) / ((NIR + 6 * Red - 7.5 * Blue) + 1), the results were strange, ranging from about -8000 to 6000. To address this, I normalized the band values (since some values exceeded 10,000) by dividing by 10,000. But even after that, some values were still greater than 1, which didn’t help. Then, I found a suggestion from somewhere in this community that I should convert the bands to TOA reflectance using coefficients from the metadata because the initial values are in Digital Numbers (DNs). After doing this, I got EVI values within the expected range of -1 to +1. But I’m not sure if this solution is correct. So, I have a few questions:Is the solutio

Resources and Q&A - Agile EO Webinar: Analysis-Ready PlanetScope Reaches General Availability

In November’s Agile EO episode, we introduced Analysis-Ready PlanetScope (ARPS)—a new offering that accelerates your analytical workflows with pre-processed, harmonized satellite imagery. Watch the webinar on-demand. Below are some questions we received during the event and resources to learn more. Questions Question: Is there a technical product sheet for today's products?Answer: The Analysis-Ready PlanetScope Technical Specification is available here. Question: How do you reduce the clouds or select the images with minimal clouds?Answer: Analysis-Ready PlanetScope does not remove clouds. It composites the best available PlanetScope pixel taken over an AOI based on the amount of cloud cover and quality. The cloud mask is produced by creating a cloud-free reference image using a year’s archive of PlanetScope, Sentinel-2, and Landsat. Question: Can Analysis-Ready PlanetScope data be accessed in Planet Explorer?Answer: No, currently, there is no support for viewing Analysis-Ready Plane
