Hi I presume this will be most use to people who generate sea-latest.zip. I use --generate-sea=..., so using the current OSM data for the area concerned, and, before loading onto a device, look at the overview map with GPSMapEdit to check the sea has worked correctly. If the country cut has problems, eg Spain without Portugal, I use sea.z ip and again check with the overview map. If still problems, try an older or newer version of sea.zip Ticker On Sat, 2021-04-24 at 13:12 +0000, Gerd Petermann wrote:
Hi all,
just noticed that this branch was not merged because I got no feedback. A few weeks ago Eric complained about bad precomp-sea data and a lot of wasted time to find it. Any reason why nobody is interested?

Hi all,
I've implemented some basic checks to detect large flooded areas in the precomp-sea data in this new branch. A link to the latest binary (r4579 as of now) is a the bottom of the normal download page : http://www.mkgmap.org.uk/download/mkgmap.html
- If PrecompSeaGenerator is used to calculate the sea data and the index check fails a warning is printed and the program ends with rc -1. - If mkgmap is used with a "dubious" sea.zip one or more messages about the problematic areas are written and the program stops with an ExitException unless option --x-check-precomp-sea=0 is given before the first input file.
The index test is normally performed once for the whole planet, so it doesn't care about the actual tile boundaries. If e.g. only a part of Australia is flooded and you create a map for the UK you'll still see the errors.
BTW: The current code (also in trunk version) doesn't support to use --precomp-sea with different values. Results are rather unpredictable.
