py_tools_ds.io.raster package¶

Submodules¶

py_tools_ds.io.raster.gdal module¶

py_tools_ds.io.raster.gdal.get_GDAL_driverList()[source]¶

py_tools_ds.io.raster.gdal.get_GDAL_ds_inmem(array, gt=None, prj=None, nodata=None)[source]¶

Convert a numpy array into a GDAL dataset.

NOTE: Possibly the data type has to be automatically changed in order ensure GDAL compatibility!

Parameters

array – <numpy.ndarray> in the shape (rows, columns, bands)
gt –
prj –
nodata – <int> nodata value to be set (GDAL seems to have issues with non-int nodata values.)

Returns

py_tools_ds.io.raster.gdal.wait_if_used(path_file, lockfile, timeout=100, try_kill=0)[source]¶

py_tools_ds.io.raster.reader module¶

py_tools_ds.io.raster.reader.fill_arr(argDict, def_param=None)[source]¶

py_tools_ds.io.raster.reader.gdal_ReadAsArray_mp(fPath, bandNr, tilesize=1500)[source]¶

py_tools_ds.io.raster.reader.gdal_read_subset(fPath, pos, bandNr)[source]¶

py_tools_ds.io.raster.reader.init_SharedArray_in_globals(dims)[source]¶

py_tools_ds.io.raster.writer module¶

py_tools_ds.io.raster.writer.convert_gdal_to_bsq__mp(in_path, out_path, band=1)[source]¶

Usage:

ref_ds,tgt_ds = gdal.Open(self.path_imref),gdal.Open(self.path_im2shift) ref_pathTmp, tgt_pathTmp = None,None if ref_ds.GetDriver().ShortName!=’ENVI’:

ref_pathTmp = IO.get_tempfile(ext=’.bsq’) IO.convert_gdal_to_bsq__mp(self.path_imref,ref_pathTmp) self.path_imref = ref_pathTmp

if tgt_ds.GetDriver().ShortName!=’ENVI’:: tgt_pathTmp = IO.get_tempfile(ext=’.bsq’) IO.convert_gdal_to_bsq__mp(self.path_im2shift,tgt_pathTmp) self.path_im2shift = tgt_pathTmp

ref_ds=tgt_ds=None
