Development of OS Satellite Image Processing/Mapping
Ken Melero writes "ImageLinks, in collaboration with Federal Agencies and Florida Tech is developing Open Source software for satellite image processing and mapping. The Open Source Software Image Map (OSSIM) experiment will be hosted on RemoteSensing.org and will demonstrate the application of open source software development techniques in meeting government requirements. See the press release for more information. " Looks cool - GPL as the license.

tcd004 Here's my Microsoft Parody, where's yours.
In several years of working in physics/programming with satellite tracking data, I found out just how bad the documentation and standards were for the various formats for data on and from satelites. The images were often fine, being compressed versions of standard formats, but what we'll be looking at here, it seems, would require additionally the exact positional data for the satellite body. Here's hoping the open source approach leads to better standards and documentation of data formats for time, position relative to the earth (and orientation), and so forth.
From experience, it will more likely result in filters of resolutions with a tremendous range, both in granularity and depth, being interpolated and patched together. I'm not sure I believe that OS will get around the traditional bailing wire and duct tape aproach of engineers in the field...

That said, I have to express a mixture of excitement and concern over what the success of this project could mean. On the one hand, it could mean that corporate culture will begin (slowly) to adapt to the Open Source model. On the other, it could mean that corporations will glean the hard work of Open Source developers and cash in, doing very little actual work themselves.
In the first case, I am happy on two counts: changing corporate culture is difficult, and if the Open Source Movement succeeds, it will be a big "feather" in our collective hat; and, corporate adaptation means that more companies are likely to open hardware specs for Linux support, and software specs for cross-platform ports.
In the second case, I have mixed feelings: having a corporate infrastructure to market and distribute Open Source works has the makings of a rather sound business model -- however, the less ethical companies out there (which, IMHO are a vast majority) may abuse the model so thoroughly that Open Source developers are alienated.
However, I cannot decide whether Open Source would be hurt, or if developers would just move thier resources to the more ethical companies. The concern is that even if the latter, the "evil" orgs can still get the work -- possibly with even less effort.
Anyone see a way around that mess?

...was impossible to trace by following the links. Assuming that the US government is involved, it is wrong.
Think about it. Tax dollars come from the people and from corporations. That includes MS employees and other software companies. They are using tax dollars to fund software written under a license that effectively tends to nationalize an industry, without any consent from the people.
This is just symptomatic of the whole leftist Clinton/Gore/Judge Jackson mentality that pervades this administration.
Once again, I have no problem if private organizations want to collectivize themselves, but when my government gets involved, warning bells start to go off. Karma to burn lately, so mod all you want.
For all intensive purposes, "whom" is no longer a word. That begs the question, "who cares"?
The Image Processing Workbench (IPW) of UCSB has been open source and freely available for years, and recent ports include Linux. Very powerful collection of command line Unix utilities written in C that can be pipelined together. It's specifically designed to work with remote sensing data although it does not incorporate image projection (mapping) and navigation functions. There is still a need for freely available OS tools for mapping and navigation.

Great, yes! I forgot about GRASS. I don't think about GIS much when thinking about remote sensing data, although some raster GISes do well with RS data sets and they do have mapping tools and so forth built in. I think the original posting is a red herring, there are a lot of relevant tools available already.

if, say, the open source world got together and built an openDoc office suite, then that would be worth talking about
I don't guess you've heard of KOffice? Check out www.kde.org and bring your C++ skills. Hackers are needed. If you don't want to hack on it, then use it. Try it out and submit bug reports.

To get that sort of resolution you would need enormous sats in orbit. Lots of sats. I don't think your voyeuristic tendancies are worth that much money.

I know what OpenDoc is. I have the OpenDoc programmer's reference and the example book with CDs on my shelf. Since Apple basically stopped supporting it, it is basically dead. Since OS/2 is practically dead, OpenDoc is practically buried.
BTW, KParts are intended to work like OpenDoc parts. May even be compatible, I'd have to check the docs again.
Actually, all of KDE is heading that way with embeddable KParts. You really need to check it out.
