The newest release of ENVI SARscape introduces significant improvements to simplify and advance your SAR analysis. The following topics are the points of
Simplify and Advance Your SAR Analysis.
The integration into the ArcGIS® environment continues with the introduction of some of the most relevant processing functions and workflows. Below is a brief explanation of what is provided with specific ENVI SARscape modules.
With the ENVI SARscape Basic module, the following functions and workflows are provided:
With the ENVI SARscape Interferometry module, the following functions and workflows are provided:
With the ENVI SARscape Interferometric Stacking module, the Persistent Scatterers function is provided.
ALONG WITH THE INTEGRATION WITH ARCGIS, ENVI SARSCAPE 5.0 PROVIDES:
A new IDL API to the ENVI SARscape's processing routines is available allowing the control and the generation of IDL Batch script and furthermore allowing inserting ENVI SARscape's functions inside an ENVI batch function.
This new tool allows subtracting or adding the Geoid related height to any input Digital Elevation Model. In previous ENVI SARscape versions this functionality was available only for DEMs ingested by means of the “Digital Elevation Model Extraction” tool.
Two new functionalities, one based on simulated SAR images and the other on manual GCP identification, have been implemented to correct erroneous orbital parameters.
The algorithm has been improved to the use of cartographic coordinates for resizing images in slant geometry (i.e. not geocoded).
A new function has been added to support the mosaic of slant- or ground-range (i.e. not geocoded) SAR data. The mosaic routines, previously embedded in the Basic module, can now be accessed through the Tools menu.
A new triangulated approach has been introduced; the algorithm has also been improved in order to better exploit the memory resources.
Phase to Height Conversion and Geocoding
The “Relax Interpolation” algorithm has been improved in order to better handle isolated pixels.
Interferometric Stacking Module (former Persistent Scatterers)
A new core algorithm has been implemented, fully developed by sarmap s.a., and which allows higher stability and increasing the resulting PS density.
The interface has been modified in order to facilitate the connection graph editing.
A new 3-D approach, which exploits the time as 3rd dimension, has been implemented in the unwrapping of the SBAS processing chain, making it much more reliable and robust in case of temporally changing coherence values.
