New Features V6.10

Highlight Feature: Industry familiar LegendView display.

System (peeking under the hood)

• DLLs reduce installed size for MacOS 8.x by 23 megabytes.
• TNTview and TNTedit have tutorial reminder/access dialogs at start up.
• New hypercube raster object losslessly compresses all hyperspectral images.
• Tutorial reminder/access dialog can be opened via help menu.
• Geospatial Rendering Engine (GRE) now separated from X and Motif.

Context Sensitive Help Procedures

• Context sensitive help system now uses HTML.
• Help is linked to section with details in reference manual.
• Add your own context help or operational notes.
• Link/start documents (Word, PDF, MPEG, ...) from your help/notes.
• Add access to web sites (e.g. microimages.com) from your help/notes.

LegendView

• Completely new, alternate LegendView display window as default providing a layer control/legend panel and a view panel.
• Combines functionality of ArcView display; the TNT Graphics Rendering Engine; measurement tools, regions, etc.; and X-based remote client/server operations.
• Panel and window toolbar are the same as the familiar (now alternate) view window.
• New toolbar icon to add layers from view window.
• Place new layer/legend panel at left or right edge of view panel.
• Drag and drop layers in layer/legend panel to control order of rendering.
• Hide or show layers in layer/legend panel.
• Delete layers with right button menu.
• Show multiline DataTips for layer names in layer/legend panel (e.g. metadata).
• Interactive renaming of layers in panel.
• Display or hide drop-down legend for each layer.
• Legend shows sample for each vector, pinmap, and TIN element style used in layer.
• Attribute controlling style shown next to legend element (e.g. soil type name).
• Display table list and allow attribute viewing.
• Auto-generated legends for raster layers: image sample, color scale, or color sample.

Visualization

• Attach a plan view showing a moving ground position to a movie.
• Attach a zoomed, moving window plan view to a movie.
• Use template graphic to position add-on special views.
• Create movies in the AVI format.

TNTatlas (free!)

• LegendView is now default display providing intuitive layer control and auto-legends.
• An object or file can start another program which uses it when selected via a link.
• Use the above to link to movie file and start viewer with that movie.

Editing

• Hot keys for frequently used operations (e.g. adding element operations).
• Line label assistant provides single table/field generation option.
• Right mouse button operation now has a "redraw" option.

Geologic Cartoscripts

• Sample cartoscripts provided for rendering linear geologic features.

Import/Export

• Import AVIRIS and ENVI hyperspectral images into hypercube object.
• Import MapInfo databases from native TAB format.
• Create, save, and use a format description to import vectors from text files.
• Import revised National Transportation Atlas Database files into vector object.
• Import IDRISI rasters.
• Import ArcInfo ASCII file into raster object.
• Import and Export AgLeader precision farming TGT files.
• Import JPL AIRSAR and other SAR from compressed Stokes Matrix to raster objects.
• import Finnish Airborne Imaging Spectrometer (AISA) hyperspectral images.
• Import Japanese Spatial Data Framework 1/2,500 urban maps into vector objects.
• Import Geosoft XYZ file into a raster object.

Database Management

• Set a maximum and minimum value for numeric fields.
• Control upper, lower, and mixed case for string fields.
• Entry into field linked to another table checked for match to primary field in that table.
• If a match is found after few characters entered autofill the field with type-over.
• Options for mismatched entry into linked field: accept, show error, or show dialog.

Hyperspectral Analysis

• Hypercube object provides lossless compressed hyperspectral images.
• Convert single hypercube object to and from multiple separate raster objects.
• Use regular visualization and hyperspectral explorer features with hypercube object.
• Toggle button automatically excludes atmospheric absorption bands from processes.
• Transform and analyze spectra using "sliding" parabolic least squares fit.
• Use Pixel Purity Index (PPI) to locate pure pixels or end-members.
• Use Derivative Matched Filtering (DMF) variant of MF to reduce terrain and noise effects.
• Locally Adaptive Constrained Energy Minimization (LA-CEM) expands MF to use spatial variability.
• LA-CEM and DMF reduce noise in results compared to Matched Filtering (MF).

Mosaicking

• Use new rubber sheeting procedure which fits every control point entered.
• Processing areas can now be hidden.

Create Geospatial Products (SML)

• Display using new LegendView (see above description).
• Create layers containing map grid, scale bar, text layer and raise and lower all layers.
• Adds extensive Import/Export (70 classes).
• Incorporate surface fitting.
• Compute slope/aspect/elevation.
• Sample SML script to alter map layout to create a map series.

Create Windows Geospatial Products (W-SML)

• Try prototype of direct Windows SML (works with any TNT key).
• Stand-alone SML interpreter, no Motif or X Server, only Windows 95, 98, or NT.
• Implement object-in, analysis, object-out script.
• Currently supports about 85% of all current SML functions without alteration.
• No display or graphics functions as yet.
• Standard Windows file section dialogs.
• Windows-like RVC object selection dialogs.
• Color Windows-based editor for preparing scripts.
