Application

The following sections provide details on the different parameters controlling the application. Interactive widgets shown below are for demonstration purposes only.

from geoapps.base.plot import PlotSelection2D

app = PlotSelection2D(h5file=r"../../../assets/FlinFlon.geoh5")
app()

Object/Data Selection

List of objects available to pull data from.

app.data_panel

See the Object Selection page for more details.

Resolution

Determine the minimum distance between data points.

app.resolution

For Grid2D objects, the resolution of the grid is downsampled uniformely to the nearest interval. For example, requesting a 15 m minimum resolution on a 10 m base grid will result in a 20 m sub-sampling.

For Points, Curve and Surface objects, the downsampling is done radially using the Scipy.spatial.cKDTree routine.
