Alexander,

I think you will find that your existing choice of environment will
determine alot about what embeddable choices you have.  By environment, I
mean platform (win32, unix/x), gui toolkit (Qt, Gtk, WxWindows, Win32)
and language (Java, C, C++, Python, etc).

Also, I am not sure what GIS capabilities you want.  Certainly there are a
number of candidates with support for displaying raster and vector data.  If
you want full GIS analysis capabilities your list of candidates will be much
more restricted.

A few possible candidates (by no means comprehensive):

  o GeoTools: Java, raster/vector
  o FMaps: C/C++, vector, X/GTK
  o OpenEV: C/C++/Python, GTK, OpenGL, raster/vector
  o OpenMap: Java, raster/vector
  o OSSIM: C++, WxWindows (win32/Unix-X), raster

Note that many Open Source applications can be adapted to be embedded in
other applications by their malliable nature.

Best regards,
