summary
Landsat archive opened in 2008 provides 30 meter resolution imagery that enables mapping changes at local scale. A multisensor workflow combines higher spatial resolution data to detect and track algae blooms since 2009 on a volcano-ringed Guatemalan lake, yielding repeatable water quality indicators. The same pipeline quantifies forest loss and crop-type change across decades because Landsat observations extend back to the 1970s, producing time series that actually reveal when and where shifts occur.
