Gridding points to raster
=========================

This example demonstrates the gridding of a point cloud into a raster using :func:`~geoutils.PointCloud.gridding`.

.. GENERATED FROM PYTHON SOURCE LINES 9-10

We open an example point cloud, an elevation dataset in New Zealand.

.. GENERATED FROM PYTHON SOURCE LINES 10-19

.. code-block:: Python


    import geoutils as gu

    filename_pc = gu.examples.get_path("coromandel_lidar")
    pc = gu.PointCloud(filename_pc, data_column="Z")

    # Plot the point cloud
    pc.plot(cmap="terrain", cbar_title="Elevation (m)")

.. GENERATED FROM PYTHON SOURCE LINES 21-22

We generate grid coordinates to interpolate to, alternatively we could pass a raster to use as reference.

.. GENERATED FROM PYTHON SOURCE LINES 22-27

.. code-block:: Python


    import numpy as np

    grid_coords = (np.linspace(pc.bounds.left, pc.bounds.right, 100), np.linspace(pc.bounds.bottom, pc.bounds.top, 100))








.. GENERATED FROM PYTHON SOURCE LINES 28-29

We then perform the interpolation

.. GENERATED FROM PYTHON SOURCE LINES 29-31

.. code-block:: Python

    rast = pc.grid(grid_coords=grid_coords)








.. GENERATED FROM PYTHON SOURCE LINES 32-33

Finally, we plot the resulting raster

.. GENERATED FROM PYTHON SOURCE LINES 33-35

.. code-block:: Python


    rast.plot(ax="new", cmap="terrain", cbar_title="Elevation (m)")
