Hi, currently DEM file contains 0m ASL area shows nice blue water. Unfortunately, in Poland we have a few quite huge depression area (<=0m AMSL). LK shows that area as a sea what is wrong.
I think that we have two - easy to implementation - alternative solutions:
1. LK shows sea ONLY for 0m AMSL - but not for <0m AMSL. I can prepare DEM file with sea with 0m AMSL and <0m AMSL for depression area.
2. LK has additional config parameter, something like "Display sea for 0m AMSL". So - I can turn it off and prepare map (not terrain) with additional layer contains sea.
I think - both solutions maintain backward compatibility with old maps.
Regards
Ryszard. |

it depend of LKM file you use, if it include water area, altitude is not used to paint water...
what lkm file do you use ? |

Are you sure? I think that terrain matters. Take a look:
Terrain OFF:
Terrain ON:
I'm using my own LKM file and there is no sea layer. |

yes i'm sure, it's due to your LKM.
Have you seen my previous JPGs? Another version. I have deleted LKM file from LK config - just to be sure. So there are no LKM layers.
Map with terrain ON.
Map with terrain OFF.

yes i have seen, maybe my first answer is not very clear, i will try to explain...
in very first version of LK8000, terrain altitude < 0 was used to paint sea, but that don't work for lot of country with negative altitude.
to solve this problem, we have include coast_area in topology file and terrain altitude is no more used to paint sea area.
but to maintain backward compatility with hold maps, if coast_area is not found in topology file ( or no topology file configured ) terrain altitude is used to paint sea area.
in your initial post you ask for solution to not paint negative altitude as sea area, answer is simple :
update your topology file to include coast layer, like it's made in this lkm file : https://drive.google.com/file/d/19cvcYDO7JInz8CiJFA-BYSHotauPshkI/view?usp=sharing |

Excellent - it's solution for me. I didn't know about that dependence.
Thanks! |

Terrain without the sea.
