NOT ALL GEOSPATIAL DATA
IS CREATED EQUAL

 
 

Get the full picture with SAR

Accurately and reliably monitoring the Earth is critical to many geophysical and geospatial applications. However, most sensors cannot capture data at night or through clouds, dust or smoke.

Synthetic Aperture Radar (SAR) data can see where other sensors have blind spots. This 24/7, all-weather data can monitor millimeter-scale changes over broad areas and provide insights that can fill in the blanks left by other sensors.

ENVI SARscape Analytics


 

ENVI SARscape Analytics is as powerful as its namesake but features a streamlined, lightweight interface accessible to beginners and pros alike. Automated, easy-to-use workflows for the most common SAR processing applications mean that you can spend less time tinkering with parameters and more time focused on analysis and results.


Easily get the answer you need from SAR data

ENVI SARscape Analytics can be accessed natively within the ENVI toolbox, ENVI modeler or ArcGIS Pro and includes powerful workflows such as:

FLOOD MAPPING

FLOOD MAPPING


The Flood Mapping analytic uses images from before and after a flood and classifies areas of standing water.


DEM EXTRACTION

DEM EXTRACTION


Two SAR scenes can be used to create a Digital Elevation Map (DEM) by comparing and using the differences in the radar signal and viewing angle between the two images.


SENTINEL DOWNLOAD

SENTINEL DOWNLOAD


Automatic download of Sentinel-1 and Sentinel-2 data. This workflow lets you choose an area of interest, dates, and other filters, and downloads multiple Sentinel-1 and Sentinel-2 scenes to use instead of having to manually download them one at a time from a web service.


SENTINEL AUXILIARY FILE DOWNLOAD

This analytic is used to download Sentinel-1 orbital files.


TIME SERIES

TIME SERIES


The Time Series analytic uses multiple SAR images to create informative layers facilitating land use analysis and change detection.

CHANGE DETECTION

CHANGE DETECTION


Change Detection uses the coherence and intensity between two scenes to track subtle changes in their structure and outputs a classification result. A secondary tool kit allows for classification refinement.


DISPLACEMENT MAP

DISPLACEMENT MAP


The Displacement Map workflow uses a pair of SAR images to show the land motion over time from the first to the second image. This analysis, known as DinSAR, is commonly used after events such as earthquakes and volcanic eruptions.


SHIP DETECTION

SHIP DETECTION


Automatic Ship Detection uses a single scene to find ships on water. This can be paired with AIS data for ship monitoring.


PERSISTENT SCATTERERS

PERSISTENT SCATTERERS


Persistent Scatterers uses time-series interferometry to track changes at millimeter scale and find areas where ground surface deformation has occurred.


IMAGE GEOCODING

IMAGE GEOCODING


Image Geocoding processes raw or satellite-view images into intensity images and geocodes them to map coordinates.



ENVI SARscape Analytics at-a-glance:

  Streamlined, user-friendly workflows
  Automatic recognition and validation of data inputs
  Entry-level price point
  Ingest commercial and public SAR data sets
  Best-in-class SARscape processing algorithms
  Ready-to-use outputs easily integrate with other geospatial products

ENVI SARscape


 

ENVI SARscape is designed for those who are knowledgeable about SAR data and processing and enables users to modify parameters to create the exact products they need.

Data support and processing

ENVI SARscape works with all commercially available SAR data as well as many non-commercial 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 and prepare it for analysis. This means more time can be spent on the data itself and solving 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 fast and 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.

Maximize the benefits of amplitude and phase

SAR data provides not only amplitude or the intensity of the backscatter response but also phase, which allows for measurement of height and displacement – a unique benefit to SAR. ENVI SARscape has tools to extract information from both the amplitude and phase, which enables users to fully utilize all aspects of SAR data to increase knowledge about areas of interest.

With ENVI SARscape, you can use the amplitude information of SAR data captured at different times over the same area to understand surface changes. Since SAR data is minimally influenced by the atmosphere, analyzing change is immediate and very efficient. Amplitude can be used to pick up physical information on the surface and is commonly used for agriculture, forestry and feature monitoring.

ENVI SARscape integrates point and area-based analysis techniques to measure displacement and deformation over time. Using the phase provides the ability to see miniscule surface changes that are impossible to see otherwise. This approach makes it possible to analyze deformation that affects both extended and localized structures related to natural or man-induced phenomena. Applications include analyzing volcanic or seismic activity, landslides, subsidence and building failures.

With ENVI SARscape, you can accurately process every type of SAR data in every way. This includes amplitude, single and multi-polarization, phase, a single SAR image or a stack of images. This allows you to easily view, observe, monitor and automatically extract information about an area as needed.

SAR ANALYSIS. SEEING IS BELIEVING.

The versatile nature of SAR data and the power of ENVI SARscape make them extremely useful across a wide-variety of applications. Here are several examples:

LANDSLIDES

Map and measure surface movement caused by human activity or from natural causes.                          

GLACIERS AND PERMAFROST

Distinguish moving from non-moving glaciers and map and monitor their movement.                            

OIL SPILLS

Detect and monitor oil spills and map their extent.                                                                           

SUBSIDENCE

Monitor surface subsidence to understand the effects of tectonic and human activities.                     

SHIPPING

Detect and identify ships (including dark vessels and semi-submersibles) and perform maritime surveillance.

AGRICULTURE

Measure plant health, growth and biomass even in areas with frequent rain and cloud cover.                 

DEFORESTATION

Monitor and calculate deforestation and forest degradation and analyze the impact.
