Frequently Asked Questions about DRAGON
What Is DRAGON?
Is DRAGON a video game?
Dragon is a precision tool for scientific research and learning. It is not a game.
It is also not a paint program or a desktop publishing program.
Is DRAGON compatible with (program X)?
Compatibility is a difficult question to answer. Dragon strives for compatibility
through the use of standard and popular file formats. Also, unlike many software packages,
Dragon provides complete documentation about its own internal file formats. Note also that
compatibility with other software is one of the significant areas of difference between
the different versions. Users who expect to work with many or unusual data formats
should consider the Dragon Professional Edition, or should contact us about specific file formats.
What standard and popular image file formats
does DRAGON support?
Dragon can import
image data from TIFF (including GEOTIFF) and from most
of the file formats used by providers of
remotely-sensed data such as LAN (Thematic Mapper)
files, BIL files, BSQ files, SPOT files, AVHRR
AGROCLIMATIC files, etc. In some cases (including
GeoTIFF), Dragon can also output data to these file
We are constantly adding new file formats to this list. If you have an unusual need, please contact us.
What standard and popular vector file formats does DRAGON support?
The current version on Dragon can read and write vectors features
stored in ESRI Shapefiles. We expect to support additional vector formats in
What kind of computer can be used for DRAGON?
At present, Dragon can run on almost any computer with an Intel/AMD processor, provided the
computer is running a compatible operating system. This includes most modern personal computers
and laptops except for Macintosh computers.
In the near future Dragon will also be able to run on Macintosh and Sun SPARC computers.
What kind of operating system can be used for DRAGON?
At present, Dragon requires one of Microsoft's Windows
(tm) operating systems such as Windows Vista, Windows
XP, or Windows 2000. However, Dragon can NOT be used
with Windows ME, Windows 98, or Windows 95. In the
near future Dragon will also be able to run on Linux
and Unix operating systems on Intel/AMD, Macintosh,
Sun SPARC, and other computers.
What about graphics cards?
For most purposes, Dragon requires at least a 1024 x
768 screen with at least 15-bit color. The standard
version of Dragon will exit with an error message if
your graphics are weaker than that.
If you have
some special display requirement, such as running
Dragon on a small screen or in grayscale only, please
contact us to discuss a special order. You will have
to accept some compromises, but it can be done.
How much memory and disk space are required by DRAGON?
Dragon is a fairly large program and sometimes
processes large data sets. Large memory and disk
space can be an advantage. However, if your computer
has enough memory for your operating system to run
reasonably fast, Dragon can probably run
also. Generally we recommend at least 512 MByte of
RAM. Dragon requires about 250MByte of disk
space. However, if you will be working with many
images you should allow for several GByte of spare
If you are using Dragon Professional to process
full-scene images, you should probably allow for several
dozen GByte for image data, and have 2 to 4 GByte of
What if I really need a DOS or Windows 95/98 version.
Dragon Release 4.1 for DOS also works fine with Windows 95 and Windows 98. It probably
would work with Windows ME also, but we've never tried to do so. Dragon Release 4.1 for MS-DOS is
still available on special order, but is no longer actively supported.
What are the DRAGON licensing restrictions?
A single copy of Dragon can be run on
one computer at a time. Customers are free to make
backups and to install the software on more than one
computer, but they are prohibited from using multiple
copies if they have purchased a license for a single
We offer two different site license options, which
are particularly intended to be attractive to
universities needing to equip a large computer lab. A
fixed seat site license permits running a specified
number of copies of Dragon at any one time. The per
seat price is considerably less expensive than the
single copy price. We also plan to offer an
organizational site license which provides the ability
to run an unlimited number of copies subject to certain
geographic restrictions. Unlike the fixed seat site
license, the organizational site license requires
payment of an annual license fee.
All users are prohibited from reverse engineering
the software as well as from reselling or otherwise
distributing the software to third parties, without our
knowledge and permission.
What are the differences between the versions?
All versions of Dragon are based on the same software libraries. The different
versions provide capabilities which are selected to match different categories of users.
Please look over our product summary for details. Also, look at the
Is there a demo or evaluation version?
You can download a free copy of
OpenDragon from the OpenDragon website.

Professional is available,
with some operations disabled.

Support for Polish is currently under
development, and we are actively seeking translators for Chinese and Japanese.
- Chinese (Traditional)
- Brazilian Portuguese

Not yet. We do expect to
support Linux at a future date. Other platforms will
follow according to demand.
Is the source code available?
Are custom or OEM versions available?
Only on special order.
Please see the description of the Dragon Engine.
