Both datasets slightly overestimate height of short shrubs & underestimate tall trees (by 6–7 m at 40 m reference height).

Getting excited for the next .
3 satellite constellation to enable increased temporal revisit, higher spatial resolution, and increase in number and diversity of spectral band-passes. Very nice!

New factsheet, nice summary of info:

muhammad pramulya Hi Muhammad! The image above is from a web app I created to explore Sentinel-2 and Landsat time series as image chips and spectral profile. There is no paper associated with it, try it here - the app includes additional info: jstnbraaten.users.earthengine.app/view/eo-timese…

Why use data to monitor ?
•Consistent observations on an annual time step
•Retrospective capacity for establishing recovery baselines
•Integration with other data sources (field plots or ) into a monitoring framework.
Lots more info in 👇👇

Landsat time series is an important data source for post-disturbance forest recovery assessment. The 40-yr 30-m resolution data provide consistent observations on an annual scale & retrospective capacity to establish spatially explicit recovery baselines. doi.org/10.14214/sf.23…

“Landsat Next will deliver more data in 1 year than has been delivered in the past 50.” Kind of scary to hear even for people with large data storage capabilities.
