GDALRasterBand-class {rgdal} | R Documentation |
Returns a two-dimensional array with data from a raster band, used internally within functions
getRasterData(dataset, band = NULL, offset = c(0, 0), region.dim = dim(dataset), output.dim = region.dim, interleave = c(0, 0), as.is = FALSE) getRasterTable(dataset, band = NULL, offset = c(0, 0), region.dim = dim(dataset)) getProjectionRef(dataset)
dataset |
An object inheriting from class 'GDALReadOnlyDataset' |
band |
The band number (1-based) to read from |
offset |
Number of rows and columns from the origin (usually the upper left corner) to begin reading from; presently ordered (y,x) - this may change |
region.dim |
The number of rows and columns to read from the dataset; presently ordered (y,x) - this may change |
output.dim |
Number of rows and columns in the output data; if
smaller than region.dim the data will be subsampled |
interleave |
Element and row stride while reading data; rarely needed |
as.is |
If false, scale the data to its natural units; if the case of thematic data, return the data as factors |
