Produce digital elevation models from bathymetry data, utilizing flow-oriented curvilinear coordinate system and anisotropic interpolation method.

bathyflowdem's Issues

Add plot of residuals

For a better understanding of the final RMSE, a plot showing the residuals can be added in the plugin's box below the RMSE value.

Make path in QgsMessageBar clickable

Then saving the results to a specific folder, the user is shown a SUCCESS message with the full path of the new layer's location within the plugin:

It will be better to make this path a link and open the file explorer location.

New raster layer's extent isn't correctly defined

In thecreate_sample_points()function in layer_helpers.py the new raster extent is defined as the boundary layer's extent:

create_raster_params = {'EXTENT': ROI.extent(),
                                'TARGET_CRS': survey_points_layer.crs(),
                                'PIXEL_SIZE': pixel_size,
                                'OUTPUT_TYPE': 5,
                                'OUTPUT': 'TEMPORARY_OUTPUT'}

But the layer extent is not always the same as the polygon. This should be changed to retrieve the polygon and use that as an extent for the new raster layer.

More flexibility with the anisotropy ratios

Currently the anisotropy ratio is only applied to the n
coordinate. It would be interesting to have two different values for the s and n coordinate so
the user can decide on which or both direction to apply the ratio.

Add progress bar

Display a progress bar at the bottom of the plugin window to inform the user about processing status.

More flexibility for user's data input

At the moment, the plugin expects the QgsVectorLayer with data points to only have a single attribute containing the value to use for interpolation. I also needs to work with layers that have more attributes.

The way the new attributes are added to the layer will need to be modified:

Implement testing

Implement testing.

Implement validation

Give the user the choice to have some more detailed data validation information such as difference between surveyed point and predicted value and/or RMSE.

Add spatial index to improve performance

Implement spatial index (QgsSpatialIndex or QgsSpatialIndexKDBush) to make the proccessing time faster.
