Database: Set Default Tables and Hide Tables     TNT 2014

   

Vector, shape, and CAD objects can include a wealth of attribute information stored in multiple database tables attached or related to the geometric elements. Some of these attribute tables may contain information that is more important to the users of the data than other tables. As you design the visual presentation of a geometric object (element display styles and DataTips), you can designate one or more default tables per element type that will automatically open when an associated element is marked in the View. You can also choose to hide particular tables, excluding them from table lists in the Display Manager.

Spatial Editor: Database Prompt and Default Record     TNT 2014

   

As you add or change geometric object elements in the Editor, you can easily provide attribute information for these elements. Several automated procedures are provided in the Editor to help you with these tasks. You can set up a database prompt to automatically prompt you to create and attach a new record in a specified table for each new element. You can also designate an existing record in a table as the default record to be attached when new elements are added. You can use database prompts and default record settings at the same time (with different tables) when you are editing geometric data with many attributes of different types distributed among a number of tables.

Vector Analysis: Run EPANET Pipe Network Simulations     TNT 2014

   

EPANET is a public-domain water distribution system modeling program developed by the U.S. Environmental Protection Agency (EPA). EPANET simulates water flow and water quality changes in pressurized pipe networks, such as a city water supply system. In TNTmips you can create, edit, import, and export vector objects representing pipe networks with attributes that conform to the EPANET data model.

The EPANET Simulation process in TNTmips (Geometric / Compute / EPANET Simulation) also lets you compute hydraulic and water quality simulations on EPANET-compliant vector objects using the EPANET toolkit library that is installed with TNTmips. An EPANET simulation tracks the water flow conditions through each network link (pipe, valve, or pump) and node (junction, tank, or reservoir) through a series of time steps.

Geomedia Publishing: Legends for Geomashup Geometric Layers     TNT 2013

   

Geomashups that you create in the Assemble Geomashup process in TNTmips can include geometric overlays created from a TNT vector object. Geometric overlays may be SVG geometric tilesets, KML geometric tilesets, or single KML files. When you create a geomashup with geometric overlays, you can choose to include a legend for any geometric 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.

Geomedia Publishing: Using SVG Tilesets in Geomashups     TNT 2014

   

SVG geometric tilesets that you create in the Export Geometric Tileset process can be used as overlays in geomashups in the Google Maps and Open Layers web mapping platforms. SVG geometric tilesets can reproduce complex styles from vector points, lines, and polygons as well as text labels, all of which are then displayed in your browser with standard graphic effects such as anti-aliasing for a high-quality rendering. Geomashups using SVG tilesets can also include clickable legends that are dynamically created directly from the SVG tiles as well as pop-in info windows showing attribute information for the map elements. The combination of information content, cartographic presentation, and efficient display afforded by SVG geometric tilesets makes them a superior choice for tiled map data in comparison to KML geometric tilesets or standard (raster) web tilesets in Google Maps and Open Layers geomashups.

Geomedia Publishing: Map View Settings in Geomashups     TNT 2013

   

As you design a geomashup in the Assemble Geomashup process, you can specify the range of zoom levels over which each individual overlay or custom base map will appear using the Min Zoom and Max Zoom fields on the Overlays and Base Maps tabbed panels. But the zoom level range of the geomashup as a whole is not constrained by these settings. By default the geomashup allows the entire zoom level range supported by the target web mapping platform, allowing it to zoom outside the scale range of your custom data.

You can use the Map View panel in the Assemble Geomashup window to limit the overall zoom level range for a Google Maps, Bing Maps, Open Layers, or Google Earth geomashup.

Import-Export: EPANET Pipe Networks in TNTmips     TNT 2014

   

In TNTmips you can create, edit, import, and export vector objects representing pipe networks that conform to the model used by the free EPANET hydraulic simulation program. The EPANET model represents physical components of a pipe network as geometric elements. Pipes, pumps, and valves are line elements (links in EPANET terminology). Pipe junctions, tanks, and reser- voirs are node elements. Many hydraulic properties of these elements, as well as simulation settings, are also stored in attribute tables.

Geometric Extract: Separate Vector Objects by Polygons     TNT 2014

   

When you use the Extract to Vector process (Geometric / Extract From / Vector) in TNTmips, you can choose to create multiple extracts at the same time using the polygons in a second vector object. One output vector object is created for each polygon in the separation vector. The polygon attribute value you select is used to name the output vector objects, which you can direct to a single output Project File or to separate Project Files (which are given the same name as the contained vector object).

Geometric Web Tilesets: SVG Geometric Structure     TNT 2013

   

MicroImages' SVG geometric tilesets are an attractive and functional way to present styled and attributed vector map data on the web in Google Maps and Open Layers. 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 and Open Layers geomashups along with standard (raster) web tilesets and KML geometric tilesets. SVG geometric tilesets load quickly at any zoom level because only a few tiles with a limited number of elements are needed for any particular view, and those tiles are in the SVG format, which is directly supported and displayed by your web browser.

Custom Google Earth Tilesets for Android Tablets in 2014DV

Custom Google Earth tilesets that you create in TNTmips for real-time 3D perspective viewing can be transferred to an Android tablet for viewing using the Google Earth app. Having your tileset on the tablet means that it is completely portable and can be viewed even in the field when the tablet does not have an Internet connection. Your WiFi-enabled tablet can also be configured so that its screen image is beamed to a large-format television, enabling a room full of people to share your Google Earth view of your custom tileset.

The series of Technical Guides illustrated below show how you can prepare Google Earth tilesets in TNTmips 2014DV for use on tablet computers. The Export Raster Tilesets, Mosaic to Image Tileset, and Subset Tileset processes can now package a small Google Earth tileset as a single KMZ file for easy transfer to a tablet. The Subset Tileset process can now also extract a Google Earth tileset from either a Google Maps or Google Earth source, including the extensive set of on-line web tilesets hosted at microimages.com. Your tilesets can be transferred to a tablet via data cable, MicroSD card, cloud storage, or e-mail.

Anyone using TNTmips 2013, the current release version, can also explore these new features in the TNTmips 2014 Development Version at no extra charge. If you have not yet upgraded to TNTmips 2013, contact MicroImages sales for more information.

Feature Mapping: Grow Prototypes and Save Features as Vector and KML

   

The Feature Mapping process in TNTmips provides a Grow and Mark Features tool that you can use to define localized feature prototypes. This tool finds a contiguous set of image cells with spectral properties similar to the point location you designate. You can use the mouse wheel to dynamically vary the variability and size of the prototype before choosing whether or not to add it as a feature. Feature Mapping also allows you to save the feature areas you have created as a TNT vector object and as a KML file, each of which includes the assigned feature names and colors.

Feature Mapping: Draw Features, Prototypes and Protected Areas

   

In addition to automated tools for classifying multispectral images, the Feature Mapping process in TNTmips provides drawing tools that let you manually modify the set of features you are creating. Using the Draw Features tool set you can draw and add individual features, draw prototypes for later assignment to features, change all or part of an existing feature to another feature type (or unclassified), and define protected areas to be left unclassified by the automated classification procedures (Define Samples and Grow and Mark Features). You can switch between classification tools at any time.

Feature Mapping: Define Samples and Mark Features

   

Feature Mapping, the interactive image classification process in TNTmips, provides several tools that let you guide your computer in identifying areas to assign to different spectral feature classes. You can use the Grow and Mark Features tool to click within a feature area and automatically find contiguous cells with similar spectra (see the Technical Guide entitled Feature Mapping: Grow Feature Prototypes). In contrast, with the Define Samples tool you identify a number of sample cells for a feature, automatically find cells with similar spectra throughout the image (a class prototype), then decide which prototype cell clusters to assign to the feature class using the Mark Features tool.

Feature Mapping: Interactive Image Classification

   

Feature Mapping is a multispectral image classification process that couples your visual interpetive skills with automated image analysis methods. The goal of this interactive process (Image / Interpret / Feature Map) is to subdivide an image spatially into a set of spectral categories, or feature classes, that you define based on your visual analysis and knowledge of the image area. Using Feature Mapping's interactive tools, you indicate image locations that are representative of a particular feature class, then let the tool automatically find image cells that are spectrally similar ...

Feature Mapping: View Features as Outlines

   

The image areas that you classify interactively in the Feature Mapping process in TNTmips are recorded as areas of solid color in a Features raster. This raster layer overlays the image you are using as a visual reference in the Feature Mapping main view, so the image areas you have already classified are obscured beneath the feature class colors. As a solution to this issue, Feature Mapping also provides a Feature Outlines raster layer.

GeoToolbox: Graph Values from Multiple Rasters/Terrains by Location

   

The GeoToolbox Profile View allows you to create cell value plots from corresponding positions in multiple raster objects or web terrain tilesets. These graphs, which plot cell value (y-axis) versus object number in the list of selected objects (x-axis), can have many applications. For example, you might have a time series of vegetation index rasters for the same area and want to plot variations in the index over time for one or more locations. Or you might want to make simple "spectral" plots for selected locations in broadband multispectral images, such as SPOT, Landsat, or WorldView.

Raster & Image Processing: Reproject Using Thin Plate Spline Model

   

The Raster Resampling using Georeference process in TNTmips (Image / Resample and Reproject / Automatic) offers a choice of mathematical models to perform the coordinate transformation to the designated coordinate reference system.

The Thin Plate Spline model is a global elastic transformation that maintains the assigned map coordinates of all control point locations but applies smoothly varying transformations between control points. Using the input control points, the transformation from image to map coordinates is modeled mathematically as the deformation of a thin elastic plate. The computed global transformation minimizes the bending energy (curvature) of this hypothetical plate. The influence of an individual control point in this model is localized and diminishes rapidly with distance from the point.
