One of the products they talk about is Ossim http://ossim.org which is a very nice open source package for supporting GIS efforts. While there is a QT GUI that works well on Mac/Linux/Windows (and now has very nice Mac and Windows installers), the real power is in the library that lets you build really powerful apps with very little code. For instance i wrote a nice drag and drop app in carbon that lets you convert a number of formats for things like digitial terrain elevation data (DTED, DEM), National Imagery Transmission Format (NITF), etc into other formats like jpeg, etc in a couple hundred lines of code most of which is the GUI code. I have done an Ada binding to the main parts of the library and while i havent put it out yet on my website, i would be willing to share it with anyone who is interested in this type of thing. i encapsulated the Ossim C++ classes inside Ada tagged types and i would like some feedback on if this is the right way to do bindings to c++ classes. I have also converted a number of the Ossim Tutorial apps to Ada as examples of using the class. I have used it in a number of apps for work as well, but i cant really share those. if anyone wants to work with this stuff let me know. jim hopperj@macconnect.com
