What is the maximum area of interest size I can define to get a list of individual scenes and not mosaics?
For an area of interest larger than 55,000 km², Planet Explorer lists monthly or quarterly Mosaics — mosaics of individual scenes. For an area of interest of 55,000 km² or smaller, Planet Explorer ...

How do I get access to the source imagery (scenes for vessels and source quads for roads and buildings)?
For Vessel Detection, each feature collection includes links to the Planet Data API to get source imagery. Use the activate link to download the source imagery.For Road Detection and Building Detec...

Month-to-month variation in road size
Planet Road Detection uses Planet Mosaics to extract roads each month. Image variability — cloud cover, sun angle, registration shifts, and so on — can cause roads to look different month over month.

Month-to-month shifts in road detection positions
Planet Road Detection uses Planet Mosaics to extract roads each month. Image variability — cloud cover, sun angle, registration shifts, and so on — can cause basemap registration to move slightly m...

Month-to-month variation in building size
Planet Building Detection uses Planet Mosaics to segment buildings each month. Image variability — sun angle, registration shifts, and so on — can cause buildings to look different sizes month over...

What is the smallest size road that can be detected?
Planet can detect roads greater than 10 m, or roughly three pixels. A road is anything a vehicle can drive on. Road Detection works best in fully developed or undeveloped urban areas, and performs ...

Roads that Road Detection can miss
Planet Road Detection uses Planet Mosaics to extract roads. Variations or gaps in the mosaics can prevent detection of portions of a road. Roads smaller than 10 m, unpaved roads, tracks, and roads ...

Month-to-month shifts in building detection positions
Planet Building Detection uses Planet Mosaics to segment buildings each month. Image variability — sun angle, registration shifts, and so on — can cause basemap registration to move slightly month ...

Smallest vessel size that can be detected
Planet can detect vessels down to about 10 m in size, or roughly three pixels. Small islands, waves, and clouds can be interpreted as small boats — even by the human eye — particularly on cloudy da...
