SNAP archetypes

The SNAP archetypes are Ellip Workflows templates that provide you with a ready-to run application to process EO data (Sentinel-1 and 2, Landsat-8, COSMO-SkyMed, RADARSAT-2 and TerraSAR-X) with a default SNAP graph.The SNAP archetypes can thus be used to develop new SNAP application where only a few customisation steps are required:

• Provide a compatible graph (tested locally for example)
• Expose as many graph parameters as desired for the fine grain processing scenarios

All these archetypes are written in Bash. The SNAP archetypes include:

Sentinel-1 one-to-one

Sentinel-1 products processed in parallel with the SNAP graph taking one Sentinel-1 product and producing one result per Sentinel-1 input. The graph provided in this archetype does the terrain correction of a Sentinel-1 product.

Sentinel-1 pair

One pair of Sentinel-1 products processed to generate a single result. The graph provided in this archetype generates an interferogram.

Sentinel-2 one-to-one

Sentinel-2 products processed in parallel with the SNAP graph taking one Sentinel-2 product and producing one result per Sentinel-2 input. The graph provided in this archetype does a K-Means Cluster Analysis of the Sentinel-2 products provided as inputs.

COSMO-SkyMed pair

One pair of COSMO-SkyMed products processed to generate a single result. The graph provided in this archetype generates an interferogram.

RADARSAT-2 pair

One pair of RADARSAT-2 products processed to generate a single result. The graph provided in this archetype generates an interferogram.

TerraSAR-X pair

One pair of TerraSAR-X products processed to generate a single result. The graph provided in this archetype generates an interferogram.
