I have just noticed 'thin blue line' (I estimate about 1 pixel wide) along every tile edge )or border). This is more obvious when I 'zoom out' and it highlights my tiles because there is this blue sea-coloured border around them.
I am using the Geofabrik GB OSM download and my relevant compile line is: --generate-sea:no-mp, extend-sea-sectors, close-gaps=10000.
Currently using mkgmap version 1827
Has this been seen before and Is there a setting for me to avoid this?.
Just a bit more information:
Strangely, I can see the blue lines at the tile borders on my Garmin GPSMAP 62s but NOT on the Etrex Legend HcX of my Wife. This is using the exact same TYP file.
On examining the screen with magnifier it seems that the lines are 2 pixels wide so I guess this is a one-pixel 'sea' border added to each tile boundary.
Any ideas?.
Bill, I have an idea. The sea bounds are made one or two long/lats larger than the tile borders. Maybe that's the cause for it. I will investigate it and post about my results. WanMil
