Sara Safavi created an article, Can Planet match this data with AIS data?
Planet can demonstrate how to match AIS data with imagery and has working relationships with existing AIS providers. Planet does not provide the AIS data or implement the integration. However, on r...

Sara Safavi created an article, Why does the bounding box not exactly match the vessel (partial fit or over fit)?
These Analytic Feeds work by detecting different features on the vessel – lines, edges, corners, shapes, etc. As the feeds analyzes the image, it may detect these features and determine a box that ...

Sara Safavi created an article, False Positive Vessel Detection Results
During the Vessel Detection feed analysis of an image, any of the following conditions or objects can result in false positive vessel detection: Waves Sea texture Islands Clouds Other image artif...

Sara Safavi created an article, Why are there duplicate detections in some AOIs?
On some days, we may have two separate satellites cross your AOI at different times of the morning. In this case, we may detect the same object multiple times in a day. These are separate detection...

Sara Safavi created an article, Can Planet run the analytic over open water (i.e. not a port)?
Our current capability is optimized for ports and shorelines only. Ports generally have stationary vessels, calmer sea states, and docked vessels. To run analytics over open water, the Analytic Fee...

Sara Safavi created an article, Does Planet classify vessel type, color, other features?
Planet is supporting Vessel Detection at the moment, though other features are being considered for the product roadmap. We’d be very interested in what classifications would be useful for you and ...

Sara Safavi created an article, Why are certain vessels missed, even though they look identical to others detected?
The Analytic Feeds have a number of layers that ultimately result in a bounding box output. Perhaps the vessel is a slightly different color, there is a haze and cloud over the vessel, and the sea ...

Sara Safavi created an article, Why do I not see any detections on certain days?
There are many reasons this could be the case – a few most likely scenarios would be: Your AOI was partly cloudy this day. If clouds blocked our view of the ground where detections would have take...

Sara Safavi created an article, What is the smallest size vessel that can be detected?
Planet can detect vessels down to about 10 m in size (~3 pixels). Small islands, waves, and clouds could easily be interpreted as small boats (even by the human eye) and particularly on cloudy days...

Sara Safavi created an article, Why are certain buildings missed?
Planet’s Building Detection leverages our monthly Basemap product to extract buildings. Due to variations or gaps in the mosaic, we may not be able to detect portions of a building. In addition, bu...
