Depends on what type of map, the level of detail, and the area you wish to cover. To give you an extreme example, when OSM servers first became available, I thought to myself, "hey, self, these maps are cool. Why don't you cache them so you can use them during balloon chases and when travelling?" so I started caching maps. I was after TN, AL, north GA, and the FL panhandle. At all (7?) zoom levels. After several days (going slow on purpose trying not to violate OSM server ToS and not be a server-hogging jerk) I had a couple hundred gigabytes of raster maps - and I was nowhere near finished. Vector maps take much less space than raster maps (in general). They also require more computation to render. Raster maps require more storage, and more IO time (more data to move from storage to memory). They take a bit of CPU time, due to the re-projection required. -Jason kg4wsv _______________________________________________ Xastir mailing list [email protected] http://lists.xastir.org/cgi-bin/mailman/listinfo/xastir
