Hi, I am having difficulty getting the overview map align with my osm data.
This is the bounding box for the data, <bound box="12.00000,102.31098,14.69655,107.65625"/> This is the bounding box of the Overview map created (mp format)Data0=(12.08496,102.34864),(14.76562,102.34864),(14.76562,107.66602),(12.08496,107.66602)
And one tile of the background Map Coverage Area (mp format) Type=0x4b Background=Y Data4=(12.00256,103.64502),(12.67273,103.64502),(12.67273,104.31519),(12.00256,104.31519)The error between the Map Coverage Area and the OSM data is within the range expected (<3m) but the error between the overview map and the map coverage area is about 4.6 km, which is unexpected. Also in mapsource there is a gap of about 580m where the img data is not displayed.
The attached picture shows how it looks in Mapsource. My options file in the style gives, levels = 0:24, 1:22, 2:20, 3:18, 4:16But I have experimented with many different values without it making any difference.
I have uploaded the osm file and style file to Dropbox (Dropbox is a nice cross-platform free service for those in need of a place to share files < 3GB total).
http://dl.dropbox.com/u/4900023/mp2osmstyle.zip (7KB) http://dl.dropbox.com/u/4900023/d-48.zip (9.2MB)What could I be doing wrong? What options could I experiment with? Where is the code that creates the overview map boundaries?
Thanks for any help or suggestions, Garvan
