MACRO MODELER – added logic operations GT (>)

What’s New – TerrSet 2020                        What’s New – TerrSet 2020

Now in its 33rd year of  development , Clark Labs continues to improve and extend the TerrSet suite of geospatial monitoring and modeling tools.

Key developments include:    IDRISI – Remote Sensing
SVM – a new classifier based on      a Support Vector Machine logic

Both soft and hard  classification  is      supported.
In addition, an automated tool is offered for parameterization      – a “grid  search ” procedure that tests varying values of parameters using      cross-validation.
Linear, radial basis function (RBF), polynomial and      sigmoid kernels are  support ed.
The user also has the ability to force SVM      to used balanced samples (equal numbers for each class) and can evaluate       the importance  of variables.
DECISIONFOREST – an       implementation  of the random forest algorithm for classification.
In addition to the hard      classification, probabilistic soft classification  images  can also be      output.
DECISIONFOREST models can also be saved and used to classify novel      imagery.
Thus models can be trained in one location, or time, and then      applied in a different location or time so long as the same variables      (bands) are used.
CONSENSUS – a module that      outputs the most common class assignment from a  group  of classifications.
This is useful for the creation of ensemble  classification s.
A new PANSHARPEN module that      offers both an Intensity-Hue-Saturation (HIS) model and a Hyperspherical      Color Sharpening (HCS) model.
SUBSAMPLE – a procedure for      sub-sampling training data, including the creation of balanced samples      where each class has an equal sized sample.
AREAFILTER – a      post-classification cleanup procedure that enforces a specified minimum      mapping unit (MMU) by removing  features  (contiguous groups of pixels)      smaller than the specified threshold.
DIGITIZE – on-screen digitizing      has been greatly streamlined to facilitate projects where a large number      of training sites need to be developed.
It also provides the option to      monitor the areas of training sites.
This is especially useful when trying      to achieve balanced samples for machine learning.

Post-classification image      editing options have also been added to the DIGITIZE menu

These      facilitate the manual cleanup of classification by direct digitization, or      by using the intersection of a digitized feature and a mask or masked      class.
LANDSAT_UPSAMPLE – a module for      the upsampling of LANDSAT 7 and 8 bands where pansharpening is not      possible.
The procedure is designed to honor the original values as      closely as possible.
SOILSALINITY – a module that      creates indices to soil salinity based on reflectance in the blue, green,      red and near-infrared bands.
In total, 10 indices are supported.
WATERINDEX – a module that      creates indices that are sensitive to the presence of water based on      reflectance data.
LOGIC – a new module that provides the ability to perform logic operations between images – e.g., GT (>), GTE (>=), LT (<), LTE (<=), AND, OR, XOR, NOT, EQ (=), NEQ      (<>).
REGRESS adds options to output predicted and residual images.
KNNREGRESS – a non-linear, .

Non-parametric regression procedure based on a K-Nearest Neighbor logic

INTERPOL (also called IDW) – inverse distance weighting interpolation modified to provide more control over the number of control points used in the interpolation.
MCE – The Multi-Criteria-Evaluation procedure now adds automatic sensitivity analysis to gauge the sensitivity of factors to changes in the factor      weights.
POLY2LINE – converts polygons files to line files.

PROJECT adds support for Cylindrical Equal Area

and has improved speed with some options.
Database Workshop now supports tab delimited files as well as import of .xlsx files (in addition to .xls files).
It also provides the ability to handle .csv and .txt files with a header row.

The Land Change Modeler has undergone a major revision:
LCM includes three new empirical modeling tools – Support Vector Machine (SVM)

Decision Forest (an implementation of Random Forest) and Weighted Normalized Likelihood (WNL).
The latter is capable of modeling large numbers of transitions in a rapid time frame.

We have also added the option to use a balanced sample with Logistic Regression

yielding transition potentials more in line with those produced by procedures such as LCM’s Multi-Layer Perceptron (MLP).
Revised to allow the automatic modeling of multiple transitions for all procedures, with the exception of SimWeight.
Adds the ability to quickly add all transitions to a single group, or to ungroup them and use automatic transition names.
Greatly improved control of project flow.
Other Improvements.

COMPOSER – now adds PNG output of compositions with lossless compression

In addition, COMPOSER offers the ability to save compositions at resolutions higher than screen resolution.
MACRO MODELER – added logic operations GT (>), GTE (>=), LT (<), LTE (<=), AND, OR, XOR, NOT, EQ (=), NEQ (<>).
A wide variety of hotkeys have been added to facilitate user interaction.
In addition, the user has the ability the customize the hotkey assignments.
GDAL conversion utility – adds batch import, and has been updated to GDAL Version 2.4.1.
In addition to the above, many improvements have been made to the speed of existing modules through a combination of 64 bit versions (TerrSet automatically switches depending on your operating system), algorithm changes and multithreading.
Code signing certificates have been added to every module to enhance system security.
TerrSet Explorer.
Facilitates the display of color composites made from separate bands.
Select any three bands, right click and choose the option to display as a color composite.
Now supports deletion to the recycle bin (default) or permanent deletion (shift-delete).
