IFSAR elevaton data integrated with Landsat spectral data, Avawatz Mountains, CA

Avawatz Mountains, CA

Integrated elevation and spectral data

Datasets: IFSAR elevation data, Landsat MSS data.

This is a study that exploits both elevation and spectral data to extract landform features that could not be extracted otherwise.
