Hi Charlie,
I get a different error with UK contour lines from SRTM data:
SEVERE (Polyline): Problem writing line (class uk.me.parabola.imgfmt.app.trergn.Polyline) of type 0x20 containing 2 points and starting at http://www.openstreetmap.org/?lat=51.41591&lon=-8.33332&zoom=17 SEVERE (Polyline): Subdivision shift is 0 and its centre is at http://www.openstreetmap.org/?lat=51.61371&lon=-6.94443 &zoom=17 SEVERE (Polyline): deltaLong = -64727 SEVERE (Polyline): Problem writing line (class uk.me.parabola.imgfmt.app.trergn.Polyline) of type 0x20 containing 2 points and starting at http://www.openstreetmap.org/?lat=50.30011&lon=-4.08691&zoom=17 SEVERE (Polyline): Subdivision shift is 0 and its centre is at http://www.openstreetmap.org/?lat=50.55436&lon=-6.21011 &zoom=17 SEVERE (Polyline): deltaLong = 98948 SEVERE (Polyline): Problem writing line (class uk.me.parabola.imgfmt.app.trergn.Polyline) of type 0x20 containing 2 points and starting at http://www.openstreetmap.org/?lat=50.30584&lon=-4.08691&zoom=17 SEVERE (Polyline): Subdivision shift is 0 and its centre is at http://www.openstreetmap.org/?lat=50.86086&lon=-6.21011 &zoom=17 SEVERE (Polyline): deltaLong = 98948
Like with Apollinaris, the compilation still finishes and the tiles work fine in the GPS.
Yeah, these errors still occur. I did spend some time trying to eradicate them but gave up in the end as a solution was not forthcoming. What's odd about your messages is that they say the lines only contain two points. Are they long straight lines? Cheers, Mark
