[OSM-dev] Problem with Postgresql / Mapnik / SRTM Contours

[Keith Sharp]

Hello,

Jon Burgess came up with the solution on IRC - the ordering of layers in
the osm.xml file was wrong, and I needed to reduce the extents.

I moved the "coast-poly" layer above the three contours layers and
changed the extent parameters to read "-179,-85,179,85".

I have noticed some data corruption to the east of the summit of Ben
Nevis there is a vertical stripe of weird artefacts.  This can been seen
on the Cycle Map:

http://www.opencyclemap.org/?zoom=13&lat=56.80244&lon=-5.01835&layers=B000

It seems to stretch for a long way north to south.

Anyone have any thoughts as to what is causing this?

Keith.
