[gdal-dev] Gdal_grid with a mask layer?

Hi, I have depth data from a lake as scattered points and I would like to convert them into raster DEM. Unfortunately this lake is not a rectangular, north oriented one but it has a curvy shoreline and lots of islands. In my first trials the resulting DEM leaks away from the water to the dry g

[gdal-dev] GPKG: Drop table but how to drop the rest?

Hi, I wonder if it could be possible to do something like "DROP CASCADING" in GeoPackage and delete the spatial index by the same. It will for sure be unusable once the table is dropped. I feel that SQLite does not support that because cascading drop seems to require that parent and child table

Re: [gdal-dev] GeoPDF content inverted as GeoTIF

Hi, There is something odd in the PDF. It is without coordinate system and perhaps because of that the top-left coordinates are (0,0) and north coordinate is increasing from top to bottom. Probably the "Invalid length for GPTS object" error does not have any effect on this. gdalinfo loopmap.

Re: [gdal-dev] Question: Creating overviews

Hi, That is normal. Overviews are kind of support files for the main image and geotransform can be stolen from there. With internal overviews in TIFF that's also the only possibility. If you need standalone downsampled images create them with gdal_translate or gdalwarp. -Jukka Rahkonen- Gane

Re: [gdal-dev] strange grid pattern when reprojecting

Hi, Gdalwarp is the tool to use and usually it works well but your case is not the most common one "lunar south polar DEMs in stereographic projection to gnomonic projection." Best if you could put a sample image available somewhere but perhaps but there are some documents about advanced trick
