The Landsat satellite mission delivers imagery every 16 days from nearly every place on the earth at a high spatial resolution (30m pixels). We have harnessed these data to automate a process to rapidly quantify open surface water and wetland habitats in the Central Valley. This nearly fully automated system makes processed and summarized data available every 4 to 10 days after the satellite image is acquired. The system makes use of a water classification model first reported by Reiter et al. (2015) and then calibrated for Landsat 8 by Elliott et al. (2016).
Central Valley Water products available below include:
- Individual scene classifications.
- Mosaicked scenes that represent the whole Central Valley together.
- View water maps and extract customized spatial extents.
- View graphical summaries of water distribution.
- Cloud filled images also available.
