Image Processing: Resampling Methods TNT DV2011
Rescaling a raster object or reprojecting it to a different coordinate
reference system involves creating a new raster cell grid on
a different alignment than the original raster. A value for each cell
in the new raster object must be computed by sampling or interpolating
over some neighborhood of cells in the corresponding
position in the original raster object. This resampling procedure
is a component of a number of processes in TNTmips, including
Automatic Resampling, Auto Mosaic, and Export to Tilesets,
among others. These processes offer a number of different
resampling methods to compute the new raster values.

Multiple Year Nebraska Geomashup
Source: 2003 to 2010 USDA imagery
Each summer USDA coordinates an interagency National Agriculture Imagery Program (NAIP) to collect 1-meter color orthoimagery of the United States. This geomashup overlays this imagery of Nebraska for the years 2003 to 2010. Using this geomashup it is easy to compare changes in land use, cropping patterns, urban development, ... at this 1-meter resolution over this 7 year interval.
To prepare this example, the NAIP's annual county orthoimage files have been converted by TNTmips into a standard web tileset of Nebraska for each year. These annual tilesets are then selected in the TNTmips Geomashup process where the mashup's user interface is designed. In just a few seconds this process combines the links to these tilesets and the required HTML and JavaScript into the geomashup (i.e., HTML file) used directly by each of the links at the left for viewing in all popular browsers.

Tilesets: Merge Structures TNT DV2011
Features Expanded ... version 2011 provides several ways of merging tilesets:
- Spatial Merge
- Zoom Level Merge
- Merge in Place
Multiple tilesets of the same type (e.g., Google Maps, Google Earth, or ...) can be combined into a single tileset in the TNTmips merge process. A spatial merge is similar to mosaicking images. IN this merge the input tilesets cover independent geographic areas (e.g., islands). A Zoom Level merge combines input tilesets that nominally cover the save geographic area but have different and, perhaps scale dependent content (e.g. different types of roads). Merging in place inserts tiles from a new or updated tileset into an existing tileset.

Tilesets: Checking Spatial Properties Using Tile Maps TNT DV2011
Standard web tilesets (Google Maps, Bing Maps, Google
Earth, and NASA World Wind) can contain millions of small
individual raster files organized in different zoom level directories
and their nested subdirectories. It is thus not practical
to assess the completeness and speed of display of a web
tileset by examining its file structure or by viewing every
tileset area at every different zoom level. Therefore,
TNTmips Pro provides tools for verifying the integrity of web
tilesets you might acquire from various sources.

Super-DRG versions of the USGS 1:24,000 and 1:25,000 Contour Maps.
A TNT geomashup of tilesets illustrates this improved topographic map coverage as a transparent county map overlay on multiple years of 1-meter color imagery.
The W.E. Upjohn Center for the Study of Geographical Change (UCGC) at Western Michigan University has used high precision flatbed color scanners and a suite of commercial software packages to prepare new and improved digital color raster versions of this basic map series. Approximately 60,000 map sheets covering all the United States at various scales have been scanned and the Center has completed the rasterization of this basic map series and all the other USGS smaller scale topographic maps of the United States for their internal use. The production aspects of this effort used multiple TNTmips for georeferencing, goespatial analysis scripts (SML scripts), and job processing on multicore Mac and Windows computers.
For more information on this Center see https://ucgc.welborn.wmich.edu/ and contact the Center at cgc-upjohncenter@wmich.edu.

Tilesets: Extract Structures TNT DV2011
You can extract standard web tilesets (Google Maps, Bing Maps,
Google Earth, and NASA World Wind) from larger tilesets using
the Extract Tileset process in TNTmips Pro (Tileset /
Extract). The process allows you to select one or more input
tilesets to extract from; the selected tilesets can be overlapping,
adjoining, or spatially separated. You can designate a
clipping area individually for each input tileset to define the
portion to extract and/or select a Bounding Region to apply to
all of the output tileset extracts. You can set buffer distances
for both clipping areas and the bounding region to automatically
enlarge the designated area(s) to provide additional image
context. New tiles are created for each new extracted tileset,
leaving the input tilesets unaltered.

TNTmips Pro allows you to display a LIDAR point cloud in the standard
LAS file format as a virtual surface. The virtual surface can be colored by
elevation, shown in grayscale shaded-relief, or in a combination of shading
and elevation color. The virtual surface is constructed on-the-fly
from a subset of the points visible in the view, so displaying the surface
is as fast as displaying the points themselves.

LIDAR: Auto-Linking to LAS Point Clouds TNT DV2011
You can view and use LIDAR point clouds in
the standard LAS file format directly in
TNTmips Pro. The first time you select an LAS
file for viewing or other use, a number of autolink
procedures are carried out to prepare the
file for efficient use. Because LAS files may
contain tens of millions of points, the points
must be scanned to build a search tree that allows
fast access to the points and their
attributes. This scan takes only a few seconds.
A boundary region is also created automatically
for LAS files containing LIDAR swath data. You
can also choose or create the point classes that
will be available for use with the point cloud and specify a coordinate reference system if
if it is not specified in the LAS file.

LIDAR: TNTmips Used in Monitoring River Health TNT DV2011
Terranean Mapping Technologies, a
MicroImages reseller in Brisbane, Australia, recently
completed an award-winning project with the Murray-
Darling Basin Authority to use airborne LIDAR
surveys to characterize river channel form and vegetation
for the basin. TNTmips standard features
and scripts written in the TNTmips Geospatial Scripting
Language (SML) were used extensively to
efficiently process and analyze the LIDAR data to
produce stream and vegetation statistics. The automated
workflows implemented via SML script were
critical in implementing analytical procedures that could
be undertaken by GIS operators with no training in
geomorphology, yet produce robust, objective, and repeatable
measures of
river health.

Japan 10 Meter Contours in Google Maps
(added as transparent overlay - tileset rendered from ~4600 shapefiles)
See http://www.opengis.jp/tileset/index.html
for complete coverage of Japan.
OpenGIS, the authorized MicroImages reseller in Japan, has used TNTmips to create tilesets of the 10 meter contour and other topographic map features for all of Japan. These tilesets use only PNG tiles to publish these map features to provide a transparent overlay for use in popular geoviewers. These tilesets for all 47 prefectures (provinces) in Japan can be viewed as transparent overlays in Google Maps from the OpenGIS web site using the link shown above. This sample uses small geomashups for each geoviewer at microimages.com each of which links to the Nagano Prefecture tileset published on this reseller's web site in Japan.
Each of these map tilesets depicts topographic contours color-coded by elevation using a style script in the TNTmips Display process. A number of other reference layers are also shown in various colors, including coastline, water boundaries, road edges, railway centerlines, building footprints, and administrative boundaries, each with styling also set up in TNTmips. For each prefecture map, all map layers were displayed together in TNTmips with appropriate styling and converted to the single Google Maps tileset you are viewing here using the Render to Tileset procedure. The maximum Google Maps zoom level for each tileset is 16. At this zoom level each screen pixel depicts a ground area about 2 meters across at these latitudes. The complete set of tilesets for all 47 prefectures at the link noted above includes about 2.3 million tile files and requires 23.3 GB of hard drive space.
The source data for all map layers is the Kiban Chizu Joho (Fundamental Infrastructural Digital Map Information) published by the Geospatial Information Authority of Japan (GSI) at a native scale of 1:25,000 (http://www.gsi.go.jp/ENGLISH/page_e30031.html). There are approximately 4600 paper maps in this series. The digital version of these maps for each prefecture is available for free download from GSI (http://fgd.gsi.go.jp/download/, in Japanese) or can be ordered on CD. OpenGIS converted each map layer from its native XML format to a shapefile using a GSI utility program. All map feature shapefiles were imported to TNT vector objects for added flexibility in styling, with the exception of building footprint shapefiles, which were used directly. The approximate total size of all input files is 10.9 GB.

Tilesets: Validating Structures
Standard web tilesets (Google Maps, Bing Maps, Google
Earth, and NASA World Wind) are conceptually simple hierarchical
directory structures that can contain millions of small
individual raster files in several very common formats. However,
it is impossible to systematically view every tile file at every
zoom level. You are unlikely to visually identify a local problem
in a tileset that was incorrectly designed or built, has
been subsequently damaged, or undergone some other undesirable
modification at some particular zoom level and
geographic location.
The Validate Tileset process scans every directory and tile
file in a standard web tileset to detect, report, and wherever
possible repair the tileset.

Tilesets: Managing Structures
Use the Tileset Manager process in TNTmips
to update tilesets, zip tilesets, add/delete zoom levels, and more. After a tileset structure is created, it may be desirable to delete,
remake, or add lower-detail zoom levels without remaking the entire tileset.
A large tileset can also confound even the lastest versions of Windows and Mac OS, which
cannot efficiently handle operations on millions of files in a single directory or directory hierarchy. This is especially true
of operations on the entire tileset, such as copying, zipping, or deleting. The Tileset Manager can zip the tile files into
one zip file per directory to reduce the overall file count to a level that these operating systems
can handle efficiently. It can also unzip a directory-zipped tileset.
You can also edit the TSD file linked to a tileset or create or recreate a
TSD link to a tileset. The HTML and KML auxiliary files of a tileset can also be updated in this process to take advantage of new capabilities
that are added and supported in upgrades to TNTmips. You can operate on tilesets one at a time
or select several tilesets with similar structures to process together. Tileset Manager operations can be run immediately
using the Run button or directed to the TNTmips Job Manager using the Save Job or Queue Job icon buttons.

Sample Script: Export 3D Cross-Sections to Google Earth
MicroImages has created a script using the TNT geospatial scripting language (SML) that automates the export of one or more manifold 3D cross-section objects to a KMZ file. This allows the section or sections to be viewed immediately in 3D in Google Earth in their correct geographic positions and orientations. The sample SML script creates a COLLADA file and corresponding PNG image file for each selected cross-section, creates the KML file that positions these models, and packages all of these products in a single KMZ file (ZIP file with a .kmz file extension) for easy use in Google Earth.
Two versions of the cross-section export script are available. They differ in the method used to animate the cross-sections and limit use of the exported KMZ file to specific Google Earth versions:
ExportMultiSectColladaKMZ.sml: KMZ useable in all Google Earth versions
ExportMultiSectColladaKMZtrack.sml: KMZ file useable in Google Earth 5.2 and later. Smoother animation using element.

Geomedia Publishing: Managing Custom Base Maps for Geomashups
The Assemble Geomashup process in TNTmips (Main /Assemble / Geomashup) allows you to mashup your own tilesets with geodata
layers from remote sources for viewing in a web geobrowser (Google Maps, Bing Maps, or Google Earth). An overview of this process is
provided in the Technical Guide entitled Geomedia Publishing: Introduction to Geomashups. You can add one or more local or web
tilesets as either base maps or overlays, which are treated differently in a geobrowser. A geomashup can include more than one base map,
but only one can be displayed at a time in a geobrowser. Overlays provide more viewing flexibility, as multiple overlays can be displayed
simultaneously, and each overlay can be provided with controls allowing the viewer to toggle it on/off and to dynamically vary its
transparency.

Tilesets: Remote Diagnostic Tool
Every web tileset created in TNTmips is automatically provided with a remote diagnostic tool to permit the designer of a
tileset to check its integrity at any time. The standard HTML files produced with every web tileset created in TNTmips
contain a link to this tool in the JavaScript library at microimages.com. The tool is activated by left-clicking on a hidden
button in the upper left corner of the browser view.

Tilesets: Provide Access to Public Imagery
High-resolution image and terrain coverage is now available from a variety of sources.
TNTmips can transform a collection of orthophotos or a terrain of 10 GB, 100 GB, or 1 TB into the tileset structure
required by these popular web-based geoviewers (e.g. Google Maps, Google Earth, or Bing Maps) or related desktop
applications (e.g. Google Earth or NASA World Wind). A custom tileset of an entire city's centimeter-range image
coverage can be prepared to use as a single layer in any of these viewers. Once the tileset is prepared, it can be added
to your web site using the sample HTML/JavaScript client automatically produced with the tileset by TNTmips or
using your custom HTML page. TNTmips also provides a Geomashup process that you can use to design a custom
combination of one or more local or remote custom tilesets, base and overlay layers from Google or Bing Maps, and
standard or custom tools and controls.

Tilesets: Link to a Structure
Anyone's map, image, plan, or other spatial
data published on the Internet as a Google
Maps, Bing Maps, or World Wind standard
tileset can be used in the TNT Professional
Products. In order to view such a tileset in a
view in TNT, its content and structure must
be defined by a small TileSet Definition
(TSD) link file.
Every tileset created by TNTmips is automatically
provided with a TSD file that is
updated by any TNT process that alters the
tileset's content. The Link to Tileset process
in TNTmips can also create a TSD file for
any standard tileset conforming to one of the
structures noted above and whose directory
structure can be read (i.e., it resides on a local
or network drive), even if some other
software built the tileset.

Tilesets: World Wind Structure
You can convert very large images or image collections into
tilesets for use in NASA's World Wind using the Auto Mosaic
and Export to Tilesets processes in TNTmips.
This tiling system is optimized for World Wind's
global 3D Earth model, in which higher-resolution tiles are
shown in the foreground and lower-resolution tiles in more
distant parts of a perspective view. This tiling system enables
World Wind to rapidly identify and load only those tiles
that are currently in the view and to determine the appropriate
level-of-detail to show for each area of the 3D view.

Database: Hierarchical Picklists
A TNT attribute picklist is a custom list you set up
from your database table that contains the allowable
attributes for elements in a geometric object. A picklist
lets you quickly assign attribute values to elements.
A series of Technical Guides with substantial basic
information about picklists is available (see
microimages.com/documentation/TechGuides/
75PicklistIntro.pdf or search Tech Guides for
"picklist"). It is possible that your picklist may be
quite long. If there are natural groupings in the picklist,
such as cities, animal types, or landcover classes, you
can use these natural groupings to condense the list
and create a hierarchy to select from.
