Purpose
In this page some Modeler Examples are presented.
To perform these examples take a look at the dedicated tutorials in C:\Program Files\SARMAP SA\SARscape\doc folder.
Data used in the tutorials (3-10) are available in our FTP site, please, contact us at support@sarmap.ch to get login credentials.
1.DataPreparation: This model allows users to import generic SAR images; to download the SRTM3 V4 DEM based on a imported reference image; to extract a spatial subset using an area of interest.
2.DownloadSentinel1ImportDownloadSrtm3V4Sampleselection: This model allows users to download Sentinel-1 data, to import the downloaded images; to download the SRTM3 V4 DEM based on the imported reference images; to extract a spatial subset using a geographic region or geographic coordinates.
3.DownloadSentinel1IwImportSampleSelectionITS:This model allows users to download GRD Sentinel-1 data from July 1st to 31st 2018 given an area of interest for a specific relative orbit, to import the downloaded Sentinel-1 images; to download the SRTM3 V4 DEM; to extract a spatial subset using a vector file; to coregistrate the subsampled images; to apply the De Grandi Spatio-Temporal filtering; to geocode the filtered images; to view the filtered images, to extract multitemporal features from the geocoded images, to view to the computed multitemporal features, to collect the results as outputs.
4.Ccd: This model creates a geocoded coherence map between two acquisitions.
5.CcdIlu: This model allows users to multilook data; to coregistrate the subsampled images; to apply the De Grandi Spatio-Temporal filtering; to geocode the filtered images; to view the filtered images, to extract multitemporal features from the geocoded images, to view to the computed multitemporal features, to collect the results as outputs.
6.CcdTimeline: This model allows users to multilook data; to coregistrate the subsampled images; to apply the De Grandi Spatio-Temporal filtering; to geocode the filtered images; to view the filtered images, to extract multitemporal features from the geocoded images, to view to the computed multitemporal features, to collect the results as outputs.
7.InSARDEMGeneration: This model generates a DEM using Interferometric SAR data. It allows users to generate an inteferogrametric derived DEM given a Reference and a Secondary complex data using the following steps: generation of the interferogram, filtering and computation of the interferometric coherence, phase unwrapping; transformation of unwrapped phase information into height values trough refinement and re-flattering process.
8.InSARDisplacementGeneration:This model allows users to generate inteferogram given a Reference and a Secondary complex data, the steps, to filter and compute the interferometric coherence, to unwrap the phase of the interferogram; to transform the unwrapped phase information into displacement values trough refinement and re-flattering process using GCP, to convert phase to displacement and geocode the results.
9.Its: This model allows users to multilook data; to coregistrate the images; to apply the De Grandi Spatio-Temporal filtering; to geocode the filtered images; to view the filtered images, to extract multitemporal features from the geocoded images, to view to the computed multitemporal features, to collect the results as outputs.
10.MetaTasksInsarDisplacementAndCombinatioDisplacement: This model allows users to perform a combination displacement using the displacement metatask previously created. The first step to perform this model is to copy the displacement metatask "SARsMetataskInSARDisplacementGeneration.task" in the C:\Program Files\Harris\ENVI55\resource\templates\tasks\SARscape and reload ENVI.
