I have created a rectangle <br>area with contours using phyghtmap and then clipped it to europe.poly <br>using osmosis.<br> <br>I'm working with splitter 421. My first split of data went wrong, some <br>parts of north Scandinavia was missing. After some trying, I have found <br>that adding option --polygon-file=europe.poly helps and map contains all <br>data. But at the same time trimming of tiles stopped working and I'm <br>getting some big empty tiles.<br> <br>I have attached a picture, showing all examples of splits. You can see, <br>that without bounding polygon trim works but some data is missing. And <br>with polygon trim doesn't work.<br> <br>My map will be transparent, without background polygon. I prefer to get <br>tile area covering only existing data, which require trim to work. And I <br>don't like empty tiles.<br> <br>I'm not sure what could help to debug this problem. Source data is about <br>1.3GB, I can upload it.<br> <br>-- <br>Best regards,<br>Andrzej<br></pre><br>_______________________________________________
