BTE Distorsion Calculator

Browser-based projection tool

The BTE Distorsion Calculator is my browser-based tool for examining local scale in the projection used by a BuildTheEarth workflow. It brings geographic inputs and projection explanations together in a French-language interface.

A global relationship such as one block to one meter does not, by itself, explain every local measurement in a map projection. The calculator provides theoretical and empirical modes so a builder can compare the model with measurements taken in-game instead of silently treating them as interchangeable.

What the project does

Enter latitude and longitude points in the theoretical mode.
Compare with an empirical mode based on in-game measurements.
Load the Schwarz–Christoffel conformal.lzma grid when using that model.
Inspect the projection pipeline explanation and the supplied Chambord example.

Environment and requirements

A JavaScript-enabled browser. The interface can load a conformal.lzma grid; its displayed projection mode should be checked before interpreting a calculation.

Getting started

Open the calculator, choose a mode and inspect the grid status before entering coordinates. Use the provided example to understand the input format, then work with points relevant to your build. Keep a record of the input points and projection mode when comparing results with a Minecraft measurement.

Scope, limitations and attribution

Without a loaded grid the interface indicates a gnomonic fallback. Results depend on the model and inputs; this page does not claim certified surveying accuracy or independent numerical validation. The tool explores scale, rather than importing buildings into Minecraft.
