2018年3月15日 · I use GDAL 2.2.1, released 2017/06/23 on Windows 10. It was install with pre-compiled packages. I usually use gdalwarp, gdal_translate or gdal_grid as commands for single use, or with Python bindings for larger programs. I haven't found a way to use Windows GPU, even with a few options I try such as -wo "USE_OPENCL=TRUE".

2018年4月8日 · Create a gdal.WarpOptions object and pass it to gdal.Warp as the options argument, just as you are doing (although you can skip the fourth line as you are creating the same object on the fifth line). Create a dictionary with the arguments and pass it as keyword arguments to gdal.Warp. For example:

While I don't know why GDAL provides this overlap in functionality, be sure to set the cache for gdalwarp to make it really fast: # assuming 3G of cache here: gdalwarp --config GDAL_CACHEMAX 3000 -wm 3000 $(list_of_tiffs) merged.tiff Be sure to not define more cache than having RAM on the machine.

The shapefile should have a .prj file which defines the projection. You can use it together with one of the following 3 options to get either the proj4 string, WKT definition or EPSG code.

2020年4月14日 · I cannot find any solid info on this and its a pretty rudimentry GIS process. I have 2 shapefiles. One shapefiles is a single large polygon. The other is a larger multipolygon. I need to clip the

GDAL supports three lossless compression algorithms for the GeoTiff format – Packbits, LZW and Deflate. You can use the compression methods with GDALs creation options. gdal_translate -of GTiff -co "COMPRESS=LZW" -co "PREDICTOR=2" -co "TILED=YES" uncompressed.tiff LZW-pred2-compressed.tiff

2015年10月1日 · Hi, I'm struggling to provide the info you asked. I'm using Python GDAL binding and I'm unsure how the commands you specifiy correspond to a Python command. In any case, I'm using GDAL-1.11.2-cp27-none-win32, as acquired from here. I'll update my post with some stats on the original .tiff. –
