Library to enable easy use of the Orfeo ToolBox (OTB) in Python
Project description
pyotb: a pythonic extension of Orfeo Toolbox
pyotb wraps the Orfeo Toolbox (OTB) python bindings to make it more developer friendly.
Key features
- Easy use of OTB applications from python
- Simplify common sophisticated I/O features of OTB
- Lazy execution of in-memory pipelines with OTB streaming mechanism
- Interoperable with popular python libraries (numpy, rasterio)
- Extensible
Documentation hosted at pyotb.readthedocs.io.
Example
Building a simple pipeline with OTB applications
import pyotb
# RigidTransformResample application, with input parameters as dict
resampled = pyotb.RigidTransformResample({
"in": "https://some.remote.data/input.tif", # Note: no /vsicurl/...
"interpolator": "linear",
"transform.type.id.scaley": 0.5,
"transform.type.id.scalex": 0.5
})
# OpticalCalibration, with automatic input parameters resolution
calib = pyotb.OpticalCalibration(resampled)
# BandMath, with input parameters passed as kwargs
ndvi = pyotb.BandMath(calib, exp="ndvi(im1b1, im1b4)")
# Pythonic slicing using lazy computation (no memory used)
roi = ndvi[20:586, 9:572]
# Pipeline execution
# The actual computation happens here !
roi.write("output.tif", "float")
pyotb's objects also enable easy interoperability with numpy and rasterio:
# Numpy and RasterIO style attributes
print(roi.shape, roi.dtype, roi.transform)
print(roi.metadata)
# Other useful information
print(roi.get_infos())
print(roi.get_statistics())
array = roi.to_numpy()
array, profile = roi.to_rasterio()
