Sarscape Envi 5.0 is a powerful software for processing and analyzing synthetic aperture radar (SAR) data. It is an add-on module for ENVI, a leading image analysis software that supports a wide range of geospatial applications. Sarscape Envi 5.0 enables users to perform various SAR operations, such as interferometry, polarimetry, change detection, ship detection, and more.
In this article, we will highlight some of the key features and benefits of Sarscape Envi 5.0, as well as the system requirements and data support. We will also show you how to get started with Sarscape Envi 5.0 and where to find more resources and tutorials.
Key Features and Benefits of Sarscape Envi 5.0
Sarscape Envi 5.0 offers a comprehensive set of tools and workflows for SAR data processing and analysis. Some of the key features and benefits include:
SARscape tasks and metatasks: These are compatible with ENVI Modeler, a graphical user interface that allows users to create custom workflows by visually connecting tasks. SARscape tasks encapsulate the processing steps of Sarscape Envi 5.0, while SARscape metatasks combine multiple tasks into a single task for convenience. Users can also create their own tasks and metatasks using the ENVI task API (application programming interface).
Integration with ArcGISÂ® Pro: Users of ArcGIS Pro can add SAR processing tools that leverage the power of ENVI and Sarscape Envi 5.0. The ENVI Py module is a standalone Python API that is available free to enable this integration of ENVI, Sarscape Envi 5.0, and ArcGIS Pro.
Additional SAR file support: Sarscape Envi 5.0 supports several new and improved SAR data formats, such as ASNARO-2, SICD, PAZ-1, RISAT-1 Level 2, Sentinel-1 Amazon format, UAVSAR SLC, HISEA-1, and StriX.
MICCD (Multi Inverse Coherence Change Detection): This workflow generates an RGB color composite for the visualization and identification of coherence temporal changes. It can be used for applications such as land cover mapping, deforestation monitoring, urban expansion analysis, etc.
Interferometry workflows without GCPs (ground control points): These workflows allow users to generate digital elevation models (DEMs) from SAR data without using GCPs. They include InSAR DEM and Stereo DEM workflows.
Interferometric Stacking: This module enables users to monitor the temporal evolution of surface deformations using SAR data. It includes two methods: Incremental PS (Persistent Scatterers) and SBAS (Small BASeline). Both methods have been improved in terms of performance, accuracy, and usability.
Other data types: Sarscape Envi 5.0 also supports other data types that can be used in conjunction with SAR data, such as AIS (Automatic Ship Identification) marine traffic, ECMWF (European Centre for Medium-Range Weather Forecasts) meteorological data, OpenStreetMap vector data, etc.
System Requirements and Data Support
Sarscape Envi 5.0 requires ENVI 5.4 or higher to run. It can be installed on Windows or Linux operating systems. The minimum hardware requirements are:
IntelÂ® Coreâ¢ i7 processor or equivalent
16 GB RAM
500 GB free disk space
Graphics card with OpenGLÂ® support
Internet connection for license activation
SAR processing can be extremely resource intensive. Depending on the datasets and operations used, a better hardware configuration is recommended. This includes the storage space used to store intermediate files during processing.
