Perform a bootstrap-style analysis using Leapfrog EDGE in just 5 steps

One simple yet effective method for testing estimation sensitivity is to run a bootstrap analysis. This is when a sample or set of samples is intentionally removed from a dataset, an estimation is performed in the location of the missing samples, and the estimated result is compared back to the samples.

The tools and workflow built into Leapfrog EDGE make this a simple operation to perform at a block level by comparing the results of two different estimations.

1. Create a standard estimator

The first step to running a bootstrap is to create an estimator using all data required. For this example I will use the LMS1 domain from the Leda training dataset, and will be estimating the Zn grades within that volume.

When time is your enemy, you need your software on your side

By Seequent Product Manager PJ Hollenbeck

All projects have their challenges, but those with a fast turnaround have a special set of problems and pressures.

A succession of accelerated construction deadlines may call for rapid iteration of geological models to meet the shrinking timelines. You might need to develop multiple hypotheses from the data you have, often in a very short space of time.

That would be ok if the software you were using was built from the ground-up specifically with geologic modelling in mind, but often it isn’t. Instead, you may be relying on tools co-opted from another industry or discipline and not intended for the ‘artform’ of geological modelling. Not only will that tend to make the initial modeling process slow and difficult, but when new data comes in – as it frequently will – it could take days, even weeks to update the model. Meanwhile, the project is already underway and costing money.

Collaboration is easier when you can work directly with a range of data sources

By Seequent Product Manager, Pat McLarin

Collaboration is key in the success of any ground engineering or environmental services project.

However, while the teams involved may be keen to share their data, ideas and detailed designs with others on the site, the software they are using may have different ideas.

Human collaboration can be tripped up by the difficulty of getting different data formats to work together. That shouldn’t be the case, though it’s not hard to see why it happens.

Every stage of a project’s workflow requires its own software package. Ground investigations, topological surveys, GIS, engineering designs, geological and geotechnical models will all have their own variations as each specialist area has its own particular outcome to achieve. That will shape the data format, leading, inevitably, to many of those formats being incompatible.

This can make progressing from step to step difficult, costly and frustrating. Technical experts can waste valuable time manipulating data – sometimes manually, sometimes through multiple software packages – and risk losing key information along the way.
