Max OSM zoom level wrong

Trailfinder

Hello,

after adding a new OSM source, e.g. "http://c.tile.opencyclemap.org/cycle/", and choosing max. level 18, the maximum resolution ("1:1 pixel mapping") is 1.194 m/px, not 0.6. Analyzing http stream, I realized that level 17 tiles have been requested from the server.
That's not a severe bug, one can choose the next level, but I just want to report it here.

Regards,
Helmut

Helmut,

Which version of Global Mapper are you using? It seems like this used to be an issue but I thought it had been fixed.

Helmut,

Right you are, there was an off-by-1 error when calculating the number of zoom levels. I've got that fixed now so going forward new sources with new builds should get the right max zoom level to start with. I have placed a new build at http://www.globalmapper.com/global_mapper13.zip with the latest changes for you to try. Simply download that file and extract the contents into your existing v13.xx installation folder to give it a try. If you are using the 64-bit v13 version there is a new build at http://www.globalmapper.com/global_mapper13_64bit.zip .

Let me know if I can be of further assistance.

Thanks,
