[mkgmap-dev] What should be in the global index by default?From Gerd Petermann GPetermann_muenchen at hotmail.com on Sun May 7 16:20:24 BST 2017
Hi Andrzej, thanks for the hints reg. Mapsource. I've not noticed the option "Find nearest places" (Ctrl+Shift+F). You are right, this seems to ignore the index and shows all possible catgories and the search field for strings is named "Containing" and works like that, "net" finds Planet and Netto. The normal find (Ctrl+F) depends on the index. The dialog is probably created based on data in Mdr18+Mdr19, not Mdr4. I try to get a Nüvi from my mother to find out more details. Maybe index usage also depends on the number of tiles in map.

One uses index, second search near current position and probably uses data directly in img. You can see both versions in Mapsource. Under "Find" menu there are options "Find Places", which uses index and "Find Nearest Places", which doesn't. If you start "Find Places", then you get 4 categories. I guess they could represent 4 different section of index. These are: cities, features (POIs), addresses and intersections. Under feature you find categories and subcategories. These are device specific, could be different in a GPS. I think categories are dependent on index too, since map created by mkgmap behaves differently than cgpsmapper version, even if they contain the same POIs. Search in BaseCamp is weird. I think developers got some idea to integrate multiple algorithms into single search. It took them years to get it working and it still confuses me. Search in GPS seems to work similar to Mapsource. If you search for a name, then most probably it uses index. I'm not sure about search for a category. I think outdoor GPS starts with search near current position but maybe car GPS uses index. -- Best regards, Andrzej _______________________________________________ mkgmap-dev mailing list mkgmap-dev at lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
