Landclass Question

[connieguy]

Tom,

   I am currently working on a new version of MXY6 - Oakes Field, Nassau. The Landclass for the area contains a number of grass rectangles which look completely out of place.

LWM Viewer shows that these are placed there by a stock scenery bgl - PK 927230. This is in NAME/scenery with the same date in 2003 as the others - i.e. it has not been replaced at any time. If I delete it the rectangles disappear. Your thoughts and advice would be much appreciated, as always,

Ken

PS This is the stage just after moving the airport in ADE, because FS9 stock had it in the wrong place by about a mile. The coastline is not too good either.

Tom,

   I have solved it by creating a Ground2K4 area specifically for the rectangles, deleting the polys and then drawing high rise areas round them. Before I deleted the polys it did not work. Clearly polys means more than grass areas associated with airfields.

Ken/Tom,

LWM also shows that the big patch sits astride areas of Large City Hi Rise and Large City Suburban non grid. Replacing these blocks with say grass still leaves the wooded square on top.

Very odd indeed. Manual decompile of 927330 and search and delete these patches perhaps?

PK files are parks, and I believe they are VTP2 polygons. To remove them you would need to use a program like SBuilder and exclude parks (polygons) from the area

Good solution Ken.

Thanks Bill. It is rather pleasing when you blunder your way to something that works. Oakes did include a small lake, which is still there, and the original FS9 location can be seen from the one to the bottom right, which I am happy to leave there. Now when I connect with Plan G things are pretty much where they should be. John does have an album on it but there are no charts of any kind for Oakes. It was replaced by Pyndling late in 1957, but that originated in the war, as Oakes did, and had always been there in some form. If we release this it will include both Oakes and Pyndling. John's album covers both.

Tom, do these PK files serve any good purpose? Seem very odd. One example slightly nearer home for me which uses a PK is Richmond Park just east of Heathrow but is it any different from just using the standard Park landclass which can be added with LWMViewer? The only thing I can see is that it might make a more precise area whereas standard landclass gets merged into adjoining landclass blocks.

What you say last is the reason MS uses VTP2 polygons for parks. They have sharp borders and can be any size. If you create a park landclass tile it is much larger and will have merged borders.

[connieguy]

Cannot the park landclass - No 134 - be added in Ground 2K4 and therefore be any shape you want and with precise borders? There are various types of forest which would also work just as well and might even look better.

[Tom/CalClassic]

That’s exactly what I am talking about - Ground2K4 also creates VTP2 polygons, the same as SBuilder. But LWM Viewer creates landclass tiles, a completely different thing.
