Report open datasets

Source: R/gdal_helpers.R
dump_open_datasets.Rd

dump_open_datasets() dumps a list of all open datasets (shared or not) to the console. This function is primarily intended to assist in debugging "dataset leaks" and reference counting issues. The information reported includes the dataset name, referenced count, shared status, driver name, size, and band count. This a wrapper for GDALDumpOpenDatasets() with output to the console.

Usage

dump_open_datasets()

Value

Number of open datasets.

Examples

elev_file <- system.file("extdata/storml_elev.tif", package="gdalraster")
ds <- new(GDALRaster, elev_file)
