Should have seen this problem before, seems I looked only at routing / search 
issues before committing r4360 :(

Betreff: AW: MKGMAP lost precision.

Hi John,

thanks for reporting. I can reproduce the error but I do not yet see where it 
is.
Looks like mkgmap is dropping on point in each shape. Will have a closer look 
tomorrow.

Gerd

Betreff: MKGMAP lost precision.

Hi Gerd,

I decided it was time to install a more recent version of MKGMAP. I have been 
running 4286 but downloaded 4398.

My maps contain the Microsoft/Bing building outlines for the US so I am using 
Level0=24.

With 4286 the result is good (screenshot 704) with 4398 the rectangles have 
become triangles as if precision is being lost (705).

I am compiling from .MP files and a typical building is :

[POLYGON]
;   RhodeIsland.geojson 161666
EndLevel=3
Type=0x13
Data0=(41.682688,-71.277508),(41.682688,-71.277476),(41.682596,-71.277476),(41.682596,-71.277366),(41.682748,-71.277366),(41.682748,-71.277508),(41.682688,-71.277508)
[END]

Regards,

John
