DemTools.jl is a Julia package for processing digital elevation models. It currently provides Laplacian filtering utilities for smoothing DEMs while controlling the wavelength scale and amplitude reduction of removed terrain roughness.
Disclaimer: This package was created for the "VAW AI tools get-together" event. It is a small demonstration project showing how I use the Codex AI agent from VS Code, the CLI, and GitHub to implement features, review pull requests, and explore AI-assisted software development workflows. The package is entirely vibe-coded and is not intended for serious use.
