Actually, the OSM tile code DOES cache the maps it downloads, and it's not supposed to be downloading the same ones over and over. The code does seem to spend a lot of time thinking about downloading, though, even when it's got all the tiles cached. I haven't looked at the code to see why. It always displays "Downloading tiles..." when it gets to a new area, and there's always something of a pause. When it's actually downloading tiles, though, it moves on to "Downloading tile X of Y". If it already has them cached it doesn't do this and skips to "Reading tiles..." directly. It could be that the downloading code is still contacting a server and querying whether the tile in the cache is outdated. The cache is supposed to work if you're off line, too. I have not tried it in a long time, though. -- Tom Russo KM5VY SAR502 DM64ux http://www.swcp.com/~russo/ Tijeras, NM QRPL#1592 K2#398 SOC#236 http://kevan.org/brain.cgi?DDTNM echo "prpv_a'rfg_cnf_har_cvcr" | sed -e 's/_/ /g' | tr [a-m][n-z] [n-z][a-m] _______________________________________________ Xastir mailing list [email protected] http://xastir.org/mailman/listinfo/xastir
