Hey all, I'm puzzled because I vaguely remember that it used to be possible to generate the .shx file, that is that we could rebuild the index from a .shp file. As I understood it, the .shp format was not necessarily well behaved---one could construct files that would cause infinite loops or topological inconsistencies---however, in most cases, an index could be built using only the geometries. 1) Is my memory correct, and it is conceptually possible to regenerate an index file? 2) Is the gt/udig requirement for this file simply due to a limitation in our current capabilities?
