Version 5.0 of 3D Nature's World Construction Set photorealistic terrain modeling, visualization, rendering, and animation software (http://www.3dnature.com) is capable of reading and using SDTS DEM files.
Advanced Topographic Development and Images (ATDI) provides the ICS Map
Server package that allows import and export of SDTS DEMs, re-projection,
tiling, and generic management and manipulation of cartographic data. ICS
Map Server is a software system designed to manufacture and manipulate
digital cartography. Import your SDTS data directly into ICS Map Server,
merge multiple files, overlay the DTM with an image (USGS Topo Quad or DOQQ
Orthophoto) and export a complete project in another format.

Applications Software Technologies, Inc.'s
GIS Solutions group has developed SDTS translators
for the TVP and TNP profiles. These translators are
part of the GeoMorph product. GeoMorph can preview and
translate GIS data between fifteen (15) different desktop mapping
formats, including MapInfo MIFF (MIF/MID), AutoCAD r12
DWG and DXF, Microstation IDGS(DGN), ESRI Shape(SHP),
and SDTS. The GeoMorph system will allow you to
view free government SDTS data and import it into
your favorite Windows mapping package, or to convert
your mapping files into SDTS format.
Companion products currently in development will allow
software developers to add file formats to the growing
list of formats GeoMorph supports, and to put GeoMorph's
Import/Export technology directly into their applications,
so they can support all of the supported file formats as if
they were the application's

Avenza Software Marketing Inc. supports SDTS in its MAPublisher 2.0,
which imports popular GIS formats into high end graphics programs for
cartographic and graphics management, and final EPS output. At this time,
SDTS import is vector only. All other MAPublisher imports -- USGS DLG,
AutoCAD DXF, MapInfo mid.mif, ArcView shape, ARC/INFO generate, and
geo-referenced TIFF and JPEG -- are imported with all database attributes
intact and editable. Completed files can be saved as PDF for cross-platform or
MAPublisher is available for Adobe Illustrator (Macintosh) and Macromedia
FreeHand (Windows 95/NT). Avenza is a third-party developer for Adobe and

Cad Easy Corporation's DTM programs for AutoCAD R14 or 2000 have been
upgraded to accept DEM files made using the SDTS2DEM.EXE and SDTS2DEM32.EXE
converters. Previous releases would only accept an original DEM file from
the USGS. Subsequent releases are expected to read the appropriate DDL file
directly without conversion. The converters, tar and gzip programs, and
directions for using them are included with all Cad Easy DTM programs.
EasySurf Release 5 (dated 3/7/2000) for AutoCAD R14 and 2000, is an
affordable full blown 2D & 3D DTM earthworks package with all the
capabilities of packages costing thousands more. Inputs can come from
virtually any source, survey data, DEM files, 2D or 3D contours and now
EasySite Release 2 (due for release July, 2000) is a revolutionary new
graphics presentation tool for Architects, Landscapers, Designers,
Contractors, Builders, Planners, Civil Engineers, Surveyors, anyone wishing
to create and render a 3D-site model. EasySite liberates your creativity,
allowing you to play with the terrain, test alternative designs, and create
rendered presentations in minutes. EasySite runs in AutoCAD Release 14 and
2000. EasySite accepts virtually any input imaginable to create the original
surface, and with the second release, will accept files converted from SDTS.

DSpatial is an open-source software development project that is working towards providing a geospatial analysis toolkit for users of the Delphi programming environment. The first raster format to be supported by DSpatial was SDTS-RPE. The SRPE code was written from the ground up in Delphi, and consists on an ISO8211 parser, a generic SDTS module reader, and an RPE profile reader which provides the user-interface to the code. While the RPE profile is not completely implemented, it does successfully read the 1:24,000 DEMs released by the USGS.
DSpatial is released at no cost under the MPL 1.1 license and is
available at http://dspatial.sourceforge.net/ (source code only, no
ERDAS has developed a prototype encoder and decoder for the Raster Profile and has
sample data sets available for review.
of the SDTS translators will make it possible to bring data from a number of raster formats,
such as DOQ or DEM, into the IMG format, and then produce SDTS datasets or vice versa. The
SDTS Raster encoder and decoder will be included with ERDAS Imagine Version 8.3, which is
expected to be released August 1996. ERDAS Imagine Version 8.2, which is available now,
contains a TVP translator. The following enviroments are supported:
- SUN OS - SUN Solaris
- HPUX - Dec Alpha
- Silicon Graphics SGI - IBM RS/6000
- Windows NT - Windows 95

Environmental Systems Research Institute (ESRI) has included in Version 7 of the ARC/INFO product an SDTS translator. In addition to the SDTSIMPORT and SDTSEXPORT commands, there are two commands, SDTSINFO and SDTSLIST, to obtain general information about the transfer and list out individual modules within a transfer. Only Version 7.04 and later are capable of transferring multiple files in a single transfer. ESRI's white paper on SDTS is available via anonymous ftp at: ftp://ftp.esri.com/pub/marketing/white_papers (Download the free Adobe Reader)
This file is in .pdf format, and gives good step by step instructions on importing SDTS files.

Geomantics is a software development company, based in the Scottish Highlands, specializing in the application of graphical solutions to real world, particularly geographical, problems. Genesis II is landscape visualization software that, currently cannot directly import SDTS DEMs. Use of the sdts2dem.exe utility included with GenesisII allows conversion of SDTS DEMS into standard DEM format. Visit Geomantics for more information.
Golden Software, Inc., has implemented SDTS import
modules for the DLG (TVP) and DEM (RPE) profiles. DLG files are used by Golden Sofware's Surfer, MapViewer, and Didger programs to represent basemap data.
SDTS DEM data can be directly imported into Surfer for contouring,
vector fields, shaded relief, 3D visualization, volumetrics, and
extensive surface analysis.
In addition to SDTS data, Golden Software applications also import
USGS DEM and DLG files, ESRI Shape files, AutoCAD DXF, MapInfo MIF,
Windows WMF, and dozens of raster formats including TIFF, BMP, and JPG.
They support exporting to most of these formats as well.

SDTS/DEM to GeoTIFF format which maintains the geo-referencing of the data.
For more information, see:
Intergraph supports two forms of SDTS data using the MGE product line. MGE
Terrain Analyst (MTA) supports USGS DEM data in SDTS format. This product
provides an SDTS to DEM translator. The converted DEM data can then be
output to standard grid file format and used in Intergraph products that
support DTM data. MTA is available for Windows NT and Windows 95. For more
information about the MTA SDTS/DEM Translator, see: http://www.intergraph.com/mge/mta.asp
Intergraph also supports SDTS vector profile data. The software translates
any valid SDTS data to and from the MGE environment on Windows NT and
Windows 95. The translator and a metadata editor are available free of
charge through Intergraph's ftp node, with MGE Nucleus license. For more
information about the MGE SDTS Translator, see:

Manifold System Release 5.00 Professional Edition is a general purpose GIS
package that fully supports SDTS format in all forms. Manifold works with
vector drawings, raster images, raster surfaces, terrain elevation data seen
in 2D (shaded relief, slope or aspect) or 3D views using SDTS data. Manifold
automatically reads all known forms and variations of SDTS, including SDTS
DEM data in "old" and "new" versions. Manifold will extract and use all
data in SDTS files, including metadata, and will automatically link tables
and maintain relations between tables and objects in vector drawings.
