tilezilla.core module

Classes, functions, etc. core to the module

class tilezilla.core.Band(path, bidx=1, standard_name='', long_name='', friendly_name='', units='', fill=<Mock name='mock.nan' id='140629135282016'>, valid_min=None, valid_max=None, scale_factor=1)

Bases: object

Basically just a rasterio dataset with extra metadata

Basically just benefit from composition by sitting on top of rasterio over re-implementing any related methods.

Metadata will, when relevant, try to follow the variable names suggested by the NetCDF Climate and Forecast (CF) Metadata Conventions.

Parameters:

• path (str) – the path of the raster image to use
• bidx (int) – 1-indexed band from within the dataset to use
• standard_name (str) – a standard name that references a description of the variable
• long_name (str) – a descriptive, but not standardized, description of the variable
• friendly_name (str) – a cross-sensor friendly name to refer to (e.g., ‘blue’ instead of band1)
• units (str) – unit of variable
• fill (int or float) – fill value for NoData or NaN
• valid_min (int or float) – smallest valid value of band data
• valid_max (int or float) – largest valid value of band data
• scale_factor (int or float) – if present, data will be scaled by this number

band

rasterio.Band: The band from self.src opened with rasterio

rasterio._io.RasterReader: the Band dataset opened with rasterio

class tilezilla.core.BoundingBox(left, bottom, right, top)

Bases: tuple

easy access container for a bounding box

__getnewargs__()

Return self as a plain tuple. Used by copy and pickle.

__getstate__()

Exclude the OrderedDict from pickling

static __new__(_cls, left, bottom, right, top)

Create new instance of BoundingBox(left, bottom, right, top)

__repr__()

Return a nicely formatted representation string

bottom

Alias for field number 1

left

Alias for field number 0

right

Alias for field number 2

top

Alias for field number 3
