Please refer to the Supported Environments document for full details on all platforms

supported by ERDAS IMAGINE 2014. However some key changes are noted below.

Microsoft Windows 8.1 Windows 8.1 Pre Release was tested and certified as supported during the development of

ERDAS IMAGINE 2014. However the final version was not released in time to test. Status will be

announced at a later date.

Leverage your 64-bit environments ERDAS IMAGINE now supports both 32-bit and 64-bit environments. Resource intensive applications leverage 64-bit environments for increased memory access and processing speed. Some key applications that benefit from 64-bit processing:

APM – can handle much larger blocks (i.e. more imagery)

ECW and JP2 compression – Compress larger images faster

ECWP – Faster streaming

Image Segmentation – Process larger images with fewer tiling artifacts

MosaicPro – Faster processing of large projects

Ortho-resampling – Up to 40% faster when using RPC models

Spatial Modeler – More memory available for complex processing, faster execution via

multi-threading (includes many operations provided through the Raster tab)

New Platforms


ERDAS IMAGINE 2014 introduces several new technology areas beside the move to 64-bit.

Primary amongst these is an ongoing expansion of the capabilities provided by the Spatial

Modeler, including new operators for processing and analyzing point cloud data (such as LAS)

as part of your Model. Details can be found below.

Point Cloud Operators in Spatial Modeler Point Cloud data, such as LiDAR LAS files or the results of Semi-Global Matching (SGM)

processes, are becoming a common and extremely important source of additional geospatial

information suitable for applications as diverse as change detection to intervisibility analysis.

To support flexible utilisation of this important data source a suite of new Operators has been

added to the 2014 Spatial Modeler to assist in the creation of custom workflows that include

point cloud data.

Add Bias

Adds a constant bias to the elevation of selected points in a Point Cloud data and writes the

output to a new point cloud file.

Classifier

This operator lets you classify point cloud data into ground surface, buildings and vegetation.

Delete Points

The Delete operator deletes selected points from a point cloud data and writes the output to a

new point cloud file.

New Technology


Merger

The Merger operator lets you merge multiple input Point Cloud (LiDAR) data into a single Point

Cloud data.

Point Cloud Compare

This operator compares two point clouds. Point clouds are considered equal if they have the

same number of points with the same X, Y coordinates and other attributes and their Z value is

within the specified threshold.

Point Cloud Information

This operator generates basic information about a Point Cloud dataset.

Point Cloud to Raster

The Point Cloud to Raster operator creates a raster (image) data from a point cloud input.

Reclass

The Reclass operator lets you change the classes of selected points using the ASPRS

classification table (the equivalent of a raster Recode operation). The result will be written to a

new point cloud file.

RGB Encode

The RGB Encode operator lets you create a new Point Cloud (LiDAR) file with RGB information

from a Point Cloud file with no RGB information and a reference image. The resampling

method for RGB Encode is Bilinear Interpolation.

Select By

The Select By operator lets you select points from a point cloud dataset. Point selection is

performed by a combination of extent, class or return number. Other Point Cloud operators

can then be applied to the selected points.

Set Constant Z

The Set Constant Z operator set the Z value of selected points to the specified Z value and

writes the output to a new Point Cloud file.


Subset

The Subset operator lets you create a new Point Cloud file based on selected points. Point

selection can be done by extent, class or return number.

Classification operator in Spatial Modeler A new Unsupervised Classification Spatial Modeler operator has been added to ERDAS

IMAGINE 2014. Users can now include Unsupervised Classification in the models they create.

Users familiar with the Unsupervised Classification application in ERDAS IMAGINE will find the

same controls available in the new operator, including being able to specify between

Isodata1 or K Means2 algorithms, and control the number of clusters and iterations.

Segmentation operator in Spatial Modeler A new Full Lambda Schedule (FLS) Image Segmentation Spatial Modeler operator has been

added to ERDAS IMAGINE 2014. Users can now include FLS Image Segmentation in the models

they create. Users familiar with the Lambda Schedule Segmentation application in IMAGINE

Objective will find the same capabilities available in Spatial Modeler through this new

operator.

Command Line Operator in Spatial Modeler Run ERDAS IMAGINE and 3rd party executables as part of your Spatial Model process.

Dodge Plus Operator

A Spatial Model operator that provides spatially-adaptive local brightness and contrast correction for aerial photography and satellite imaging, which frequently suffer from uneven scene illumination caused by the varying position of the camera look angle with respect to the sun at a given location.

1 In this method you can set a range for the number of clusters. This is because the Isodata algorithm can perform cluster deletion, splitting, and merging between iterations.

2 This method requires you to enter a predetermined number of output clusters. Pixels are iteratively classified into this number of

clusters without any deleting, splitting, or merging during the process.


Input / Output operator Preview Prompts The Spatial Modeler now supports prompting for the values to be used where Input or Output

Ports have been added to a Spatial Model when running the Model in Preview mode. Input and

Output ports are usually used to prompt the user for variables such as file names or band

combinations, including providing bubble help to assist the user in understanding what

parameters should be defined. By extending this capability to Preview mode Models have been

made far more interactive for use as shared, generic real-time processing algorithms.

For example, a Model could be authored for real-time pan-sharpening of imagery. Running the

Model in Preview mode will now prompt the user to supply the names of the input Pan and

Multispectral images as well as any other required variables, rather than these being hardwired

into the Model and requiring manual editing by the end user.

ERDAS ER Mapper wizards using Spatial Modeler Select ERDAS ER Mapper wizards have been converted into ERDAS IMAGINE Spatial Models

and presented through a standard GUI, providing real time preview and manipulation similar to

an ER Mapper algorithm.
