[Freegis-list] Martin Reddy's Open Source Projects

[Paul Selormey]

Hello Martin,
Thanks for your contributions to the open source efforts. I have taken a lot
at your page and it is cool.
My browser, however, refused to enter the site

http://www.tsmapi.com/

is the url really correct?
I also wish to do a purely Win32 version of VRML viewer, where do I get
information
to start? Are there some libraries to use? Please help me and any
information, I completely
ignorant here.
BTW, what is the meaning of SRI? It seems to be a big and old orgnization,
but I could not
find the meaning on the homepage.

Best regards,
Paul.

Martin Reddy's Open Source Projects

Definitely, someone who would like to be here:
"I am at my happiest when I coding. I have worked on a number of software
projects throughout my personal and professional career
and where possible I try to release these as Open Source for anyone to
benefit from. That is, freely-available source code, normally under one of
the OSI-branded software licenses such as GPL or Apache. Below is a
selection of some of my Open Source projects."

So, the softwares:

DEM2GeoEG
http://www.ai.sri.com/~reddy/geovrml/dem2geoeg/
DEM2GeoEG is a program to convert US Geological Survey Digital Elevation
Model (DEM) data into a VRML .wrl file that uses the GeoVRML 1.0
GeoElevationGrid. The code is written in C and supports numerous options for
manipulating the output model.
(pls pay attention the source code doesn't have any indication of GPL or
Apache license, just a 'public domain' status)

tsmApi
http://www.tsmapi.com/
The Tile Set Manager API is a freely-available set of tools for creating
massive multi-resolution terrain models that can be browsed by the
TerraVision terrain visualization system, as well as produce GeoVRML
versions of these models. This library is maintained by a number of
engineers at SRI and is released under the Apache license.

yet another coordinate transformation tool
GeoTransform
http://www.ai.sri.com/geotransform/
The source code is available, but it's subject to the GeoTransform License
Agreement, which it not a free software license. :((

GeoVRML 1.0 Open Source Sample Implementation
http://www.geovrml.org/1.0/
Developers can obtain the full source code for the GeoVRML 1.0 nodes and
associated run-time. These are supplied in the spirit of open source to
foster exchange of knowledge and enable the community to further develop
these capabilities.
Here we have a problem:
"N.B. Part of the GeoVRML implementation is based upon the GeoTransform Java
package. This was derived from the SEDRIS Conversions API and as such comes
under the SEDRIS License.  Essentially, the GeoTransform package is freely
available and you can use it as a component of a product that you sell.
However, you cannot sell the GeoTransform package itself, and all derivative
works that you make on the package must be published openly under the terms
of the original license."
"The rest of the GeoVRML source code is released under the Open Source
Apache license."

cheers,
Felipe.
