Getting Started

Baselode is an open-source, multi-language toolkit for working with drillhole and spatial datasets in the mineral exploration and mining industries. It is available as:

• baselode (Python) — data loading, desurveying, map and strip-log visualisation
• baselode (JavaScript/npm) — data loading, desurveying, 2D strip logs, and 3D scene rendering

Prerequisites

Language	Minimum version
Python	3.12+
Node.js	18+

Installation

Python

Install from PyPI using pip:

pip install baselode

Recommended: create a virtual environment first.

python -m venv .venv
source .venv/bin/activate   # Windows: .venv\Scripts\activate
pip install baselode

JavaScript / npm

Install from npm:

npm install baselode

baselode has peer dependencies that must also be installed in your app:

npm install baselode react react-dom three three-viewport-gizmo plotly.js-dist-min papaparse

Quick Start

Python — load and inspect a drillhole dataset

import baselode.drill.data as drill

COLLAR_CSV  = "path/to/collars.csv"
SURVEY_CSV  = "path/to/surveys.csv"
ASSAY_CSV   = "path/to/assays.csv"

collars = drill.load_collars(COLLAR_CSV)
surveys = drill.load_surveys(SURVEY_CSV)
assays  = drill.load_assays(ASSAY_CSV)

print(collars.head())
print(surveys.head())

All loaders return a normalised pandas.DataFrame (or GeoDataFrame for collars) using the Baselode Open Data Model.

Python — desurvey and visualise in 3D (requires the JS module)

import baselode.drill.data as drill
import baselode.drill.desurvey as desurvey

collars = drill.load_collars("collars.csv")
surveys = drill.load_surveys("surveys.csv")
assays  = drill.load_assays("assays.csv")

traces = desurvey.desurvey_holes(collars, surveys)

JavaScript — load CSV and desurvey

import { loadAssayFile, parseSurveyCSV, desurveyTraces } from 'baselode';

const collarsText = await fetch('/data/collars.csv').then(r => r.text());
const surveysText = await fetch('/data/surveys.csv').then(r => r.text());

const surveyTable = parseSurveyCSV(surveysText);
const traces      = desurveyTraces(collarsText, surveyTable);

Running the Demo Applications

Two demo applications ship with the repository so you can see every feature in action with real GSWA data.

Demo	Stack	Description
React demo	Vite + React	Map, 2D strip logs, 3D viewer
Dash demo	Python + Plotly Dash	Map, 2D strip logs, embedded 3D viewer

For full setup instructions see the Demos page.
