• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

Replacing Excluded Water

Okay so apparently the vector shp excludes actually go by LOD block rather than actually just cutting out the data from the underneath, or at least data from an LOD cell that intersects.

With one of the islands I'm working on this means for the water exclude I've built I've now got huge tracts of landmass several miles offshore from the island.

I've been thinking about how to quickly solve this issue and replace the missing water and am wondering if I generate a waterclass map whether that would help me fill in the water again?

I've thought about doing a water polygon but that seems challenging as I'll have to create a hole for the island block on the inside of the polygon and generate a large enough polygon for the missing data on the outside... i.e. picture a square with a hole cut inside it.

I'm hoping that the waterclass bgl would be the better solution as then I don't have to worry about polygon flattening issues.

The whole reason in the first place for the water exclude is because all my water is flattened already within the elevation data bgl...

Hope someone can track with what I'm saying, in the middle of election coverage at work and my mind is scattered right now...
 
A waterclassbgl will not help.

In FSX, the process is to exclude the watermasking vector poly, then replace the watermasking vector poly.

If you have access to a GIS program, it may be possible to create a shp file from the zero elevation contours of the DEM data to make an ocean mask.

Thanks Dick, that's what I suspected... Ah time to draw the outer box... What a pain... Hopefully Prepar3d can provide a more elegant solution in future...
 
Set the QMID grid to 11. Draw your waterline from QMID11 edge to edge, complete the poly around the QMID. Select poly and use "Slice to QMID11". Delete the new polys that are on the outside of your QMID11 of interest. Then "make line from poly" to create your shoreline.

The QMID grids are one thing I'm yet to get to learn how to set up... Any good posts on the QMID stuff...
