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...

Why does the same road look different sizes month-to-month?
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.

Why do the position of the roads occasionally shift month-to-month?
Planet Road Detection uses Planet Basemaps to extract roads each month. Image variability — cloud cover, sun angle, registration shifts, and so on — can cause basemap registration to move slightly ...

Why does the same building look different sizes month-to-month?
Planet Building Detection uses Planet Basemaps to segment buildings each month. Image variability — sun angle, registration shifts, and so on — can cause buildings to look different sizes month ove...

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 ...

Why are certain roads missed?
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 ...

Why do the position of the buildings shift month-to-month?
Planet Building Detection uses Planet Basemaps to segment buildings each month. Image variability — sun angle, registration shifts, and so on — can cause basemap registration to move slightly month...

What is the smallest size vessel 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...

What Is the Term/Tenure for My Basic Education & Research Program? How Can I Extend It?
Until 2019, Basic Education & Research Program users did not have a specific end date and were therefore valid as long as their users had access to their organizational email address.The program ha...
