I am a grateful user of your map tiles. Stopped using the installer in favor of compiling the .img files into my own index files. Works fine using mkgmap. However, I've got a question. I'd like to be able to selectively replace individual tiles as I add map features to OSM. If I download a tile on date X, then on date Y (3 months in the future), I download a fresh copy and the tile number is the same am I asured that I will have a compiled map with no gaps or overlap? If there is overlap how will I know it? I'd prefer not to opverburden your servers by asking for the entire collection I am maintaining, which covers 6 states in the US and exceeds the tile count limit.

Well, the overburden happens occasionally but I'm sure your request will not cause the system to go through it's knees :-)

The way the tiles are generated now is not really compatible with your method of updating your map by downloading some -but not all- new tiles. Like greencaps says: the coordinates and tile numbers may vary on each update. I'm thinking about a way to let people like you just download the img tiles from the website without providing an too easy opportunity for leechers to just download everything everytime.

The problem with the maximum tile limit is caused by leechers who request much, if not the entire, planet on each update. That behaviour caused massive increased load on the system and bandwidth usage. Those rather few spoiled it for the rest when I added the tile count restriction. I consider the website to be a flexible service for people who travel through a few countries or who live near a border, not a service for those who wish to download large sections of continents that they will rarely travel anyway just for the sake of having it. I hope you (anyone) will accept my choices in this matter.

Maybe a smarter option could be developed to restrict abuse like maximising the amount of traffic someone generates over the course of, say, several weeks instead of the single-request-tilecount restriction that is implemented currently. I don't know really...

When is the next update planned? I have been working on some changes in the OSM data and want to see if they worked or not.

You're hooked, I can tell ;-)

The next update is staring next Thursday after the new planet dump release. I've been on holiday last week which explains the delay.

what happens if I get 2 adjoining tiles that overlap? Does mkgmap or mapsource choke? just curious.

Not 100% sure, but I guess it's not going to work. The inter-tile routing depends on special edge nodes that line-up perfectly in both tiles to be able to route from one tile to another. There also might be other caveats, perhaps not even routing related, that could happen. You could try it and see what happens...

Lambertus,

All my OSM maps in Roadtrip and on my Garmin Colorado 300 have a blue dot POI in the middle of every road.
The whole map looks like a martian with chicken pox...

From what I have found, the option
--road-name-pois= 0x2f15 (or a different code)
does this to allow searching roads. Did you turn this on recently (in the last week or two)?

Based on the reports so far, I've decided to remove the --road-name-pois feature for the next update. It does more harm then good IMHO. The country/state option in the address search on some models just needs to get fixed in Mkgmap...
