Slartibartfast - creating streams / Rivers

[Guest qowiboy]

Hello allafter a lot of tests, i arrived on a wall, and hjope someone can help me to tumb down this one:I want to create streams, that follows automatically the relief (Mesh) until it reaches no data. Such a function should be possible with slartibartfast, where a section [Rivers] and following inputs in lat/long define a "spring", and water will follow the referenced mesh.After a lot of tests i could not detect, how this function work, respectively why doesn't it function with my .inf -File.unfortunally in the slartibartfast -manual there is no example how this function should work correctly...I hope for your hints and tips, therefore i thank you for any response:.inf =*****************************BOF[Destination]DestDir = ".Scenery"DestBaseFileName = "fluss"UseSourceDimensions = 0NorthLat = -11.25WestLong = -75.000000 SouthLat = -14.062500 EastLong = -71.250000LOD = 10[LWM]SRTM = 0VectorSmooth = 8ExpandMesh = 0Coastline = 1Sharpen = 0NormalMesh = 1CoarseMesh = 0LWMVersion = 3Landclass = NoneDitherLC = 8PatchAPT = 0PatchLWM = 0UpdateWM = 0BeachWidth = 20LakeWidth = 20RiverWidth = 20[source]Type = ElevS16MSBSourceDir = "Source"SourceFile = "dem.msb"Lat = -11.0000Lon = -75.0000NumOfCellsPerLine = 4801NumOfLines = 4801CellXDimensionDeg = 0.00083263946711074104912572855953372CellYDimensionDeg = 0.00083263946711074104912572855953372ScaleInMeters = 1.00000000[WaterSource]Type = ImageSourceDir = "Source"SourceFile = "watermask.bmp"Lat = -11.250000Lon = -75.000000NumOfCellsPerLine = 10000NumOfLines = 7500CellXDimensionDeg = 0.000375CellYDimensionDeg = 0.000375[Rivers]Start = S14* 2.52', W73* 14.00', 100Start = S12* 13.22', W74* 35.24', 100Start = S11* 54.39', W73* 32.88', 100Start = S11* 15.14', W73* 49.37', 100Start = S11* 26.33', W72* 34.57', 100Start = S11* 29.02', W72* 55.94', 100Start = S11* 27.14', W73* 12.46', 100Start = S11* 41.94', W73* 19.94', 100Start = S12* 1.51', W73* 12.58', 100Start = S11* 49.04', W72* 48.71', 100Start = S13* 7.93', W72* 35.44', 100Start = S11* 56.54', W72* 33.30', 100Start = S12* 4.24', W72* 30.08', 100Start = S11* 43.01', W72* 13.18', 100Start = S11* 42.47', W72* 0.05', 100Start = S12* 57.93', W71* 27.41', 100*****************************EOFThe result is only in VTP & LWM with my watermask defined, but no more adds of other rivers.- BBfluss.bgl- LL_fluss_lwm.bgl- VV_fluss_vtp.bglthe automaically created batchfile looks like this:*****************************BOF@echo offset TOOLSDIR=C:progra~1Terrain_Toolsecho Compiling VTP...del ".SceneryVV_fluss_vtp.bgl" 2>NUL:"%TOOLSDIR%bglc" -I"%TOOLSDIR%" ".SceneryVV_fluss_vtp.bgs"echo Compiling LWM...del ".SceneryLL_fluss_lwm.bgl" 2>NUL:"%TOOLSDIR%bglc" -I"%TOOLSDIR%" ".SceneryLL_fluss_lwm.bgs"echo Resampling fine mesh..."%TOOLSDIR%resample" "fluss_new.inf"IF NOT EXIST ".Sceneryfluss.tmf" GOTO m1"%TOOLSDIR%tmfcompress" ".Sceneryfluss.tmf" temp.tmf"%TOOLSDIR%tmf2bgl" temp.tmf ".SceneryBBfluss.bgl"del temp.tmf ".Sceneryfluss.tmf" 2>NUL:goto m1a:m1pushd ".Scenery"del "BBfluss.bgl" 2>NUL:ren "fluss.bgl" "BBfluss.bgl"popd:m1a*****************************EOFFrancis - qowiboy

Hi,Looks OK to me except that all your rivers will stop at 100m ASL. Could you post the logfile that's created too? That should say whether or not it's interpreted the [Rivers] section correctly.It's covered in the manual on p.32, but only briefly. What you've got in the file seems OK but I have to admit it's been a while since I used this function :)Cheers,Jim

Hello Jim,Thank you for that very FAST answer... unfortunally i could not find any log-file, i assume it must be in the Terrain_Tools -Folder?, but analyzing your answer you gave me the essential hint, which i should try:"that all your rivers will stop at 100m ASL."1. this section did not work well without inserting the third "Z" parameter (it did not recognize anything)2. Its ASL, that means it will overflow only about 100m a.s.l., unfortunaly this area has no deeper area than ~300m ... so i should try with higher values?kind regardsFrancisi will try now with aa high value! (5000 m ASL.)

Hi,There is indeed a newer version of the program available, but I don't think there were any changes regarding the Rivers code. Worth a try though. I can't investigate tonight I'm afraid but will check tomorrow.http://www.jimkeir.co.uk/FlightSim/AutoGen/index.htmlThe third parameter to the 'Rivers' command should be optional (remember to also remove the comma before it) but if not then try the 5000m limit as you suggested. I'll take a look and verify that it *is* optional.The log you found does show that the rivers are being processed; if you can see that bit, then that's a start.Cheers,Jim

Hi,I think the problem is in the 'Source' section. Change it from:[source]Type = ElevS16MSBNumberOfSources = 9... to ...[source]Type = MultisourceNumberOfSources = 9and see if that helps.Cheers,Jim
