Error While Executing : There is not enough space on the disk

[milansoliya4210]

I am trying to run command
"C:\Program Files\Amazon Corretto\jdk17.0.11_9\bin\java.exe" -jar mago-3d-terrainer-1.10.0-release.jar java -input "D:\GIS Data\Milan\h\raw" -output "G:\GIS Data\Milan\h\tiles" -min 0 -max 10 -intensity 16 -c
for Tiff file around 25 GB approx. 90 m resolution and it failed after some time and give me message like below.

Hi @milansoliya4210 !

Actually the mago-terrainer uses a big size of temp files. If the input is 25GB, you need reserve more than the double disk space.

We are working with the mago-terrainer to improve. In the future the temp files will be deleted during the process to free memory.

Ok, Thanks For Answer

Hi @sdson can you help with like there is some extra padding kind of tiles generate with no data as like below image in top and right side so is there any way we can prevent so that it will not generate or not include in layer.json ?

[sdson]

The extra tiles with no data on the top and right side are caused by padding when the GeoTIFF dimensions are not an exact multiple of the tile size. The tiles are defined by a quadtree structure, starting with 2 root tiles at level 0. Because of this fixed tiling scheme, the quadtree always subdivides the whole extent, and if the input GeoTIFF does not align perfectly, some padding/no-data tiles are generated.

[milansoliya4210]

@sdson Is there any way we can optimized because it created two extra tiles each side but it can also fitted to square bound without this extra tiles so we can consider remove this extra padding using any command input and also not consider in layer.json ?

[sdson]

The only way to remove the padding meshes after generation would be to manually edit the quantized-mesh files and delete the triangles. However, this will create holes and break consistency between tiles at different depth levels, so it’s not a recommended solution.

[milansoliya4210]

@sdson One another thing also I have noticed that in generated file and layer.json there is mismatch, generated files are more than what mentioned in layer.json so like below image it shows x, and y of tiles in generated file and folder but in layer.json it skips 1 row and 1 column.

[sdson]

Yes, these files are generated during convertion to help the triangles refinement process. But these files does not intersects with the geotiff extension, so are no used.
