v2 v3 11 11 To determine which formats support which capabilities, use the ''--formats'' switch with pretty much any GDAL utility. Each driver will include either '''r''' (read-only), '''rw''' (read or sequential write) or '''rw+''' (read, sequential write or random write). 12 12 13 == How to improve `gdalwarp` perfomance? == 14 15 Briefly: use the warp memory and config cachemax settings. For example `gdalwarp --config GDAL_CACHEMAX 500 -wm 500` uses 500MB of RAM for read/write caching, and 500MB of RAM for working buffers during the warp. 16 17 For more details see [wiki:UserDocs/GdalWarp] ``Will increasing RAM increase the speed of gdalwarp?`` 18 13 19 == How to convert a raster to a layer of polygons? == 14 20
