Overview

SAR2CUBE as a project foresees the development of a processing chain and prototype implementation for organizing Sentinel-1 SLC data in efficient data cubes, both from the point of view of the data provider and from the point of view of the consumer of the data, to foster the uptake of SAR data into everyday processing chains. This comprises three main layers, pre-processing, data cube setup and post processing on the fly. Different implementation scenarios have been benchmarked, including necessary space requirements for hosting the data, speed of access from the user perspective and processing speed. Finally, three use cases have been defined to test the suitability of the developed SAR data cubes for analysis chains, including analysis of terrain motion with PSI techniques, land cover classification based on interferometric coherence and change detection based on back scatter time series.

Architecture

SAR Operators

SAR2Cube has built-in processes for basic and advanced SAR operators, accessible using the openEO API. The current implemented SAR operators are the following:

Spatial subsetting

The selected area of Bolzano in slant-range.

Amplitude/Intensity

Amplitude and Intensity over South Tyrol.

Interferometric Coherence

6-days VV Coherence over South-Tyrol.

Geocoding

Geocoded 6-days VV Coherence.

Use Cases

Our study area is the mountain region Trentino-South Tyrol, Italy. The mountain environment offer us several challenging areas to validate our use cases.

The mountain region of Trentino-South Tyrol, Italy.

Use Case 1: Terrain Motion with PSI

PSI comparison between PRISAR and SAR2Cube.

Use Case 2: Land Cover Classification

Classified map produced using 1 year of 6-days Coherence computed with SAR2Cube.

Use Case 3: Forest Change Detection

Detected forest changes for 2019 after the Vaia storm of late 2018, using Intensity computed with SAR2Cube.

How to access and use the SAR2Cube data and processing infrastructure?

We have created a specific video tutorial explaining how to perform basic and more advanced operations using the openEO Web Editor.
