ENVI 5.5.2

ENVI image analysis software uses scientifically proven analytics to deliver expert-level results. Businesses and organizations choose ENVI because it integrates with existing workflows, supports today’s most popular sensors, and can easily be customized to meet unique project requirements.

NVI provides a powerful API that lets organizations add their own proprietary algorithms, extend existing tools and models, automate high-frequency tasks, and string together multiple tools to produce desired outcomes.

Combine multiple tools, including image analysis functionality, to create new custom image analysis capabilities based on desired outcomes.

The new Dimensionality Expansion tool creates additional bands in a multispectral image by computing second-order statistics and other nonlinear transforms on the original bands. Having additional bands increases the dimensionality of a raster, which can help improve accuracy in some classification and subpixel target detection algorithms. The additional bands are created by computing the square roots, natural logs, squares, and cross-correlations of the input bands.

The new Spectral Library Dimensionality Expansion tool runs dimensionality expansion on a spectral library. This is useful if you create a dimensionality expansion image and you want the spectral library to match the data space of that image.

The Download Web Data menu option lets you download remote sensing data from the web, extract the data, and open the data directly in ENVI.

The Reproject Raster tool has a simpler user interface.

The Layer Stacking tool has a simpler user interface with new options to define the output extent based on the geometric intersection or union of the input images.

In the Seamless Mosaic workflow, mosaics created from multispectral images now have a band-interleaved-by-pixel (BIP) format. This significantly reduces processing time. Mosaics of single-band images will continue to have a band-sequential (BSQ) interleave.

Reading MIE4NITF files is significantly faster, especially with large files.

New spectral filter functions are available for Sentinel-2A and -2B.

A new Duplicate Selected right-click option lets you copy and paste annotation items in a view.

You can delete multiple pixel-based and polygon-based ROI records by holding down the Shift key, then drawing a polygon around the records to remove.
ArcGIS Integration

ENVI Py 1.2 provides support for the ENVICOORDSYS data type. As a result, ENVIReprojectRaster can be deployed as a standalone tool in ArcMap and ArcGIS Pro. See the Running ENVI Analytics in ArcGIS Pro Tutorial to learn more.
ENVI Modeler Updates

A new Filter Iterator node executes an operation only when a specified condition is met. This node iterates through a collection of data while also applying the specified condition.

A Run Model in Debug Mode option was added to the ENVI Modeler menu bar. When the model runs, an Execution Report dialog reports the execution times for individual nodes and for the entire model. It also reports the values used for task parameters.

Multiple Aggregator nodes can be combined; for example, using one Aggregator node to close a loop introduced by an Iterator node, and using another Aggregator node to collect items into an array.

The documentation contains more examples of using Iterator and Aggregator nodes.

If a model produces text or numeric values, you can view those values in a dialog by connecting them to a View node.
