5 December 2012
As you classify LAS point clouds in one or more steps in the Lidar Classification process in TNTmips, you have the option to save each previous classification along with the reclassified LAS file. When you view a reclassified LAS file in the Display process, you can choose any of these previous classification results to use along with the current classification as the basis for selecting and styling points for display and comparison of the classifications. |
|
29 November 2012
LIDAR point clouds may contain point returns from bare ground, vegetation, water, and man-made objects such as buildings, towers, and wires. In order to create a bare-earth terrain surface, a major application of LIDAR surveys, it is necessary to differentiate ground from non-ground returns in the data. The Lidar Classification process in TNTmips (see the Technical Guide entitled LIDAR: Automatically Classify LAS Point Clouds) includes several classifiers that you can use to automatically identify likely ground points. The Ground - Multiscale Curvature classification method is designed for use in forested areas with a relatively small proportion of ground returns. |
|
21 November 2012
A major application of LIDAR point clouds is the accurate delineation of the terrain surface. However, LIDAR data may also include point returns from vegetation and man-made objects such as buildings, towers, and wires. Creating a bare-earth terrain surface requires that these above-ground returns be excluded. The Lidar Classification process in TNTmips (see the Technical Guide entitled LIDAR: Automatically Classify LAS Point Clouds) includes several classifiers that you can use to automatically identify likely ground points. The Ground - Terrain Following method uses a fast, slope-based approach to identify ground points. |
|
14 November 2012
LIDAR point clouds may include noise points, which have anomalously high or low elevations in comparison to the elevations expected for ground, vegetation, and structures in the survey area. You can automatically reclassify noise points in one or more LAS point cloud files using the Lidar Classification process in TNTmips (Terrain / Lidar Classification) by choosing the Noise option from the Classify menu. You can choose to process points in all input classes or exclude certain classes. Points that meet the noise criteria you specify are reassigned to the high noise or low noise classes. You also have the option to mark points as "withheld", which means that they will be excluded by default from further processing. Files are processed "in place", but you have the option to save the previous classification information along with the new classification (see the Technical Guide entitled LIDAR: Automatically Classify LAS Point Clouds). |
|
7 November 2012
The Lidar Classification process in TNTmips (Terrain / Lidar Classification) allows you to automatically reassign points in one or more LAS point clouds to different classes using criteria that you specify. If the input files have already been classified, you can choose which point classes to reclassify and which ones should retain their previous classification. The process includes separate classifiers to identify ground points and noise (anomalously high and low points). |

3D stereo videos you have created from TNT stereo views can be uploaded to YouTube (www.youtube.com) so anyone can view them in stereo. If you properly configure the YouTube settings, users can view the 3D video using any available stereo device (passive stereo, active shutter glasses, or anaglyph glasses).
|
|
24 October 2012
You can create full-color 3D YouTube videos from screen recordings
of your activities (editing, sketching, ...) in a TNTmips passive
stereo view. You record the initial video of the line-interlaced stereo
view using standard screen-recording software. You then
process the video to convert each line-interlaced frame into separate
left and right images placed above and below each other in the
output video frame to create a 3D video. When you upload this
reprocessed video to YouTube and identify it as 3D, anyone can
then view it in stereo 3D using their available stereo viewing device
(passive stereo, active shutter glasses, or anaglyph glasses).

17 October 2012
Custom overlays in geomashups can be organized in overlay groups. An overlay group has a folder icon in the layer controls that allows the viewer to open (expand) the group to show the component overlays in the layer controls or to close the group to show only the group name. The overlays within a group have individual layer controls allowing them to be turned on or off, and the group has a control allowing all overlays in the group to be turned off simultaneously. |
|
10 October 2012
Fusion Tables is a Google data visualization web application that allows you to upload large data tables with point, line, or polygon geometries and easily create custom thematic maps shown in Google Maps. You can include these Fusion Tables maps as overlays in the Google Maps geomashups you create in TNTmips using the Assemble Geomashups process. Fusion Tables maps can be combined with your standard web tilesets, KML files, and SVG and KML tilesets to create data-rich geomashups. You can make geomashups with Fusion Tables you have created, or include public Fusion Tables created by others.

When you use the Vector Extract process (Geometric / Extract to / Vector), you can separate the output by attribute, such that all elements with the same attribute value are copied to the same output object and elements with a different attribute value are copied to another object. The number of elements in any output object is equal to the number of elements with the same value for the selected attribute. |

29 August 2012
When you georeference a spatial object such as a raster cross-section using the Manifold model, the 3D control points are automatically connected to form a triangular mesh that defines the projective surface for 3D perspective display. The default triangulation covers the entire area bounded by the control points and may include triangles around the boundary of the object that are outside the area you wish to be visible in the 3D display. |
|
29 August 2012
A manifold contains its own shape and position information in the form of a set of 3D georeference control points defined using the Manifold geometric model. This 3D piecewise affine model connects the control points to form a triangular mesh that defines a projective surface for 3D perspective display of the raster or geometric object manifold. The Georeference process provides a 2D view of the input object with overlays showing the control points and resulting triangulation (which is based solely on the distribution of the control points in this flat, 2D view). |
|
22 August 2012
You can export polygons, lines, or points in a TNT vector, shape, or CAD object to a Tab-Separated Values (TSV) text file (*.tsv) that you can then upload into a Google Fusion Table. You can use the Fusion Table interface to create maps from the table and set element styles to use in the maps. You can also use the Assemble Geomashup process in TNTmips to add a Fusion Table map as an overlay in a geomashup. See the sample Fusion Table geomashup.

8 August 2012
You can create Google Maps geomashups with a sidebar equipped with drawing and measuring tools that anyone can use to make measurements and to make and save annotations while viewing the geomashup in their browser. Users can add point markers and draw lines, rectangles, circles, or polygonal shapes. Any number of elements can be added, and each element can be provided with a custom name and description. Users can also obtain KML text for the entire collection of drawing elements at any time. |
|
1 August 2012
The Assemble Geomashup process provides several predefined templates that you can select to define the layout of a Google Maps geomashup within the browser window. You can set up geomashups in which the map area occupies the entire browser window, or divide the window into a map area plus a sidebar that can contain the layer controls, legends, custom text, and a logo. |

18 July 2012
This Newsletter is designed to help users of TNTmips view, edit, sketch, and annotate 2D imagery or geometric geodata in 3D. |
|
11 July 2012
The geodata in any View window in the TNT products can be rendered in stereo using a terrain layer (elevation raster or web terrain tileset) using the Stereo icon button on the View. In order to create the 3D stereo effect, separate renderings of the View's geodata are created for the viewer's left and right eye. These renderings are presented in the View in the form appropriate to your designated stereo method (see the Technical Guide entitled Stereo Viewing: Use Any Popular 3D Display Method). You can adjust the characteristics of the stereo rendering at any time using the Stereo Settings window, which you open from the View window's Options menu. |
|
5 July 2012
It is more accurate to use, create, and update geodata in a realistic stereo view than in a flat 2D approximation. Make your work and results more interesting, accurate, and satisfying. For example, interpret, annotate, create, or edit any of your geodata in stereo using drawing tools that follow the terrain. |

20 June 2012
To fully exploit the benefits of stereo viewing you need to add a new low-cost stereo viewing device to your computer. All of the TNT products support all three of the 3D viewing technologies used in new monitors, laptop screens, TVs, and projectors. None of these technologies are new, but their implementations in new products provide flicker-free, bright color stereo views. They now come with newly designed light-weight glasses that are even comfortable when worn over your prescription eyeglasses. |
|
14 June 2012
All of the TNT products support drawing in stereo on monitors or TVs that use 3D shutter glasses, polarized glasses, or new glasses-free stereo technology, as well as on any 2D monitor or TV using anaglyph glasses. When any TNT view is toggled from 2D to stereo, all of the drawing, tracing, and editing tools automatically operate on the stereo surface. High-quality full-color stereo views of geodata provides faster and more accurate tracing of natural or man-made terrain-related features. Some examples include geologic contacts, soil boundaries, landslides, fire scars, timber stands, and others. |
|
4 June 2012
Anyone in your organization can use Google Earth with the low-cost TriDef 3D Windows application to view in color stereo any Google Earth tilesets you have created in TNTmips. Your custom tilesets can be designed to show features that are not readily visible in Google Earth's native imagery, and the simple drawing tools in Google Earth can be used by anyone to sketch points, lines, and polygons over your custom overlay and save the result as a KML or KMZ file.

23 May 2012
Web tilesets contain image or map data that has been subdivided into uniformly-sized tiles created at a series of discrete map scales and stored in a predefined directory structure. This standardized structure makes web tilesets a convenient means to efficiently store and present spatial data of any detail and area. You can create different varieties of web tilesets in TNTmips using various TNT processes. This spectrum of web tilesets accommodates different forms of geospatial data and different options for viewing and using the result. More detailed discussions can be found in numerous Tileset Technical Guides and Tileset examples. |
|
18 May 2012
Web tilesets are structures specifically designed to allow geospatial data layers of any size and detail to be used efficiently over the internet or your local network. The tileset representation of your geodata layer can be stored, viewed, and used without the need for any special added software on your server. More detailed discussions can be found in numerous Tileset Technical Guides and Tileset examples. |
|
9 May 2012
You and all your associates can view and interpret any geospatial materials in color stereo in Google Earth. Simply convert your image, map, vector, CAD, shape, and other digital materials of any size to Google Earth tilesets in TNTmips. The low-cost TriDef 3D Windows application (www.tridef.com) renders your overlays and the Google Earth imagery in color stereo. |

27 April 2012
67 tutorial booklets with step-by-step procedures are available. These 12- to 72-page PDF booklets are available for download and are installed for direct access as part of your TNT product. This is a total of approximately 1800 color pages exceeding the materials in at least two textbooks. |
|
18 April 2012
When you create a geomashup with KML overlays, you can choose to include a legend for any KML layers that have points, lines, or polygons with different styles based on their attributes. Each legend entry has a checkbox that can be used to show or hide all of the map elements in that category independently from the other element categories. You can therefore use these legend controls to peform simple interactive queries by showing only map elements with particular attribute-based styles. This selectivity allows you to examine the spatial distribution of selected map features independently and to compare those distributions to map data in other layers.
|
|
11 April 2012
A geometric tileset can be used on a website to present styled map data in Google Maps for any size area. Successive Google Maps zoom levels differ in map scale by a factor of 2, so a geometric tileset may present map data over a very large range of map scales. Careful design is required to set the display styles in the TNT vector object you plan to convert into a geometric tileset so that the tileset's graphic elements are appropriately styled over its full range of map scales. |
|
6 April 2012
MicroImages' KML and SVG geometric tilesets are tiled structures that are created by TNTmips to present map data in a web browser in styled geometric form for any size area over a range of Google Maps zoom levels. The Export Geometric Tileset process, which creates these tilesets, renders geometric elements from a source vector object into KML or SVG tiles using the display style settings stored with that source object. The tiles for each zoom level are independently rendered directly from the source vector object at the map scale corresponding to that Google Maps zoom level. |
|
3 April 2012
Google Maps geomashups that you create in the Assemble Geomashup process in TNTmips can include KML overlays that you have created from a TNT vector object. When you create a geomashup with KML overlays, you can choose to include a legend for any KML layer or layers that have map elements (points, lines, or polygons) with different styles based on their attributes. The resulting legend is part of the geomashup layer controls and shows a style sample for each unique category as well as the corresponding attribute value. |
|
28 March 2012
When you render a TNT vector object to a KML file or KML geometric tileset, the attribute information you have set up for the DataTip for the vector elements is automatically transferred to each corresponding KML map feature. When the KML data is used as an overlay in Google Maps or Google Earth, this attribute information is shown in Google's info window by left-clicking on a map feature. You can vary the design of the DataTip in the source vector object to control the way in which the attribute information is shown in Google's info window.
|
|
21 March 2012
The Export Geometric Tileset process in TNTmips Pro (Tileset / Export Geometric) converts a styled vector object into a geometric tileset with your choice of either the SVG geometric or KML geometric tileset structure. These tiled structures allow you to present styled geometric data on the web for any size area and at different resolutions over a range of zoom levels. (See the Tileset Technical Guides entitled SVG Geometric Structure and Geometric KML Structure for descriptions and illustrations of these products.) Modern web browsers support the display of the geometric data in these tilesets and automatically apply enhancements such as antialiasing to provide a high-quality rendering of your map data. |
|
15 March 2012
MicroImages' KML geometric tilesets allow you to present large vector map data on the web in Google Maps and in 3D in the Google Earth browser plug-in. KML geometric tilesets use a tiled form of the Google Earth KML file format to store vector graphics and associated attribute information that can be presented on the web at different resolutions over a range of zoom levels. Because of this tiled, multiresolution structure, only a few tiles with a limited number of elements are needed for any particular view, allowing this limited data to be processed and rendered efficiently by the web browser. |
|
7 March 2012
MicroImages' SVG geometric tilesets are an attractive and efficient form for presenting styled vector map data on the web in Google Maps. SVG geometric tilesets use a tiled, multi-resolution form of the SVG file format for web vector graphics. You can use the Export Geometric Tileset process in TNTmips to render your styled vector points, lines, polygons, and text labels to SVG geometric tilesets that can be used in Google Maps geomashups along with standard (raster) web tilesets and KML geometric tilesets. |
|
29 February 2012
The Assemble Geomashup process allows you to mash up tilesets and KML files that are already posted on the World Wide Web. You can use the Add Remote Tileset or Add Remote KML icon buttons to open a selection dialog for this purpose. This Technical Guide describes procedures for quickly specifying the full web URL for your custom web layers so they can be added to the geomashup.
