Understanding precision, accuracy, and tolerance of geospatial datasets: an example based on the usage of GNSS receivers

Bonus track – the error ellipse

This text and the related exercise is mainly extracted from an article by Vincent Spruyt and implemented through the material available in the article “An Alternative Way to Plot the Covariance Ellipse“

The error ellipse, a.k.a. confidence ellipse, represents an iso-contour of the Gaussian distribution, and allows you to visualize a 2D confidence interval.

Open this second notebook to calculate and display error ellipses of your gpx datasets.
