ENVI® SARSCAPE®
Process, analyze and solve problems with SAR data
THE PROLIFER ATION OF SAR DATA
Synthetic Aperture Radar (SAR) is used around the world due to its many benefits
such as its ability to capture data at night and see through cloud cover, dust andsmoke. SAR can image a surface through vegetation, soil and ice and can easily
measure height and displacement. Because of this, there are many applications
where SAR can provide critical information about an area or objects of interest –complimenting optical imagery.
There are currently a large number of orbital SAR instruments, with more being
built all the time. An increase in free and publicly available SAR data has resulted
in a significant growth in data coverage and accessibility. As a result, SAR data isbeing used to solve problems across a wide range of disciplines including disaster
preparation and response, urban development and land use, agriculture, change
detection and monitoring across land and sea.
SAR PROCES SING AND ANALYSIS WITH ENVI SARSCAPE
For decades, NV5 Geospatial and sarmap SA have teamed up to provide ENVISARscape, making the benefits of SAR data available to everyone. ENVI SARscapeallows you to easily process and analyze SAR data for applications like surface
deformation mapping or land cover/land use monitoring, while giving you the option
to integrate this information with other geospatial products. This unique dataanalysis capability turns your data into meaningful insights and answers.

ENVI SARSCAPE IS THE
INDUSTRY STANDARD:> Use technology developed by
SAR experts and proven overtime> Easily ingest SAR data andprepare it for analysis> Quickly view, observe, monitorand extract information about
an area> Access image analysis tools andSAR processing in one package> Solve problems across a wide
variety of applications> Accurately and efficiently
analyze data at scale> Utilize all aspects of SAR data toincrease knowledge

Since ENVI SARscape is integrated with ENVI – the premier image processing
and analysis solution – you get the added benefit of image analysis tools and SAR
processing functionality in one package.

THE INTEGRATION OF ENVI AND ENVI SARSCAPEENVI is the industry standard for image processing and analysis. It is used byimage analysts, GIS professionals and scientists to extract timely, reliable andaccurate information from geospatial data and imagery. ENVI has remained on thecutting edge of innovation for more than three decades due in part to its support ofall types of data including multispectral, hyperspectral, thermal, LiDAR and SAR.
DATA SUPPORT AND PROCESSINGENVI SARscape works with all commercially available SAR data as well as many noncommercial SAR data sets including Sensor Independent Complex Data (SICD). ENVI
SARscape works with any size data and has automated tools to quickly and easily
prepare SAR data for viewing and further analysis.
A lot of time and effort can be spent making SAR data ready for analysis. However,built-in tools and workflows in ENVI SARscape make it easy to ingest data andprepare it for analysis. This means more time can be spent on the data itself andsolving problems.
Powerful tools such as the De Grandi Spatio-Temporal filter are great for reducing
noise and speckle, and automatic co-registration makes processing workflows fastand easy. Plus, ENVI SARscape’s support of cloud and enterprise environments
means users can take advantage of modern hardware and efficiently and accurately
analyze data at scale.
PRODUCE GEOSPATIAL PRODUCTS
It is easy to create products and derive insights and answers with ENVI SARscape.
These products could include a time series analysis plot of agricultural growth,
tracking surface changes for a report, detecting and mapping a harmful spill andmuch more.

ENVI SARscape was used toperform time series analysisof an oil facility near GreenVillage, Syria. The results depict
tire tracks in the sand that areunobservable with optical data.

BENEFITS OF ENVI S ARSCAPEAND ENVI INTEGR ATIONINCLUDE:> Easy-to-use interface> Seamless use on both the desktop
and enterprise environments> Access to pre-built workflows> Fusion of optical and SAR data toexploit the strengths of each datatype> The use of ENVI Modeler to easily
perform batch processing andcreate custom workflows> Access to ENVI SARscape tools
within ArcGIS®

MA XIMIZE THE BENEFITS OFAMPLITUDE AND PHASE
SAR data provides not only amplitude
or the intensity of the backscatter
response but also phase, whichallows for measurement of heightand displacement – a unique benefit
to SAR. ENVI SARscape has tools
to extract information from both theamplitude and phase, which enables
users to fully utilize all aspects ofSAR data to increase knowledge
about areas of interest.
With ENVI SARscape, you can use
the amplitude information of SAR
data captured at different times overthe same area to understand surfacechanges. Since SAR data is minimally
influenced by the atmosphere,
analyzing change is immediate andvery efficient. Amplitude can be used
to pick up physical information on
the surface and is commonly used
for agriculture, forestry and featuremonitoring.
ENVI SARscape integrates point
and area-based analysis techniques
to measure displacement anddeformation over time. Using thephase provides the ability to see
miniscule surface changes thatare impossible to see otherwise.
This approach makes it possible toanalyze deformation that affects
both extended and localized
structures related to natural or maninduced phenomena. Applications
include analyzing volcanic or seismic
activity, landslides, subsidence andbuilding failures.

shows different stages of crop growth. The source image is Sentinel-1, processed using ENVI
SARscape by sarmap SA.

With ENVI SARscape, you canaccurately process every type ofSAR data in every way. This includes
amplitude, single and multipolarization, phase, a single SAR
image or a stack of images. Thisallows you to easily view, observe,monitor and automatically extract
information about an area as needed.
