  • Automatically assign defaults when adding elements.
  • Use editing tools to add new 3D elements when overlaid on DEM.
  • Assign dangling nodes special color for quick identification.
  • Optimize label positions.
  • Improved vector filtering with interactive visual evaluation.

Vector Filtering

  • New process for vector filtering with interactive visual evaluation.


  • SPOT images converted to orthoimages using a DEM.
  • Vector and CAD overlay objects ortho-corrected along with associated images.


  • Feathering methods added for seamless mosaicking.
  • Improved bundle adjustment for indeterminate cases.
  • Multiple bands mosaicked at one time.

Hyperspectral Analysis

  • New process for analysis of hyperspectral imagery free via TNTlite.
  • Combine or build spectral curve libraries: average, resample, divide, subtract, add, maximum, minimum, and difference.
  • Edit spectral libraries: set a value, add, subtract, multiply, interpolate, smooth, normalize, and compute derivative.
  • Analyze spectral curves: Remove Continuum and Spectral Feature Fitting.
  • Import hyperspectral images and apply calibrations: Equal Area Normalization, Log Residuals, Additive Offset Calibration, and Flat Filed Correction.
  • Interpret hyperspectral images: Spectral Angle Mapper, Cross Correlation, Linear Spectral Unmixing, and Matched Filtering.

Image Classification

  • New training set editor to create, modify, and test training sets.
  • Combine training sets, set color, label, and so on, with interactive tabular approach.
  • Vector polygons or points converted to training sets.
  • Use mask to define area to classify.
  • Apply apriroi probabilities and unknown class in maximum likelihood.

Network Analysis

  • New process uses network vector, control attribute table, and node attributes.
  • Find best routes with waypoints.
  • Allocate routes to and from locations.

Surface Fitting

  • Breaklines and polygons can represent drainage, ridges, lakes, ... as boundary conditions in surface fitting processes.
  • New bidirectional fitting method for geophysical and other transect-like surveys.

Create Geospatial Products
