Version 1223 was commited by steve on 2009-09-23 22:27:31 +0100 (Wed, 23 Sep 2009) BRANCH: mdr Start a branch for the global index work (mdr). The plan is to quickly create the minimum amount that works, merge it back and then repeat. I am going to read img files to create the index as there is lot of information that is needed in them and it would be useful to create one separately anyway. A similar decision was made wrt the overview map, and so the same code can be used to finally implment a better overview map too.
