MorphoVolc DEM Interface is an open-source web platform designed to simplify and standardize the morphometric analysis of volcanic edifices based on digital elevation models. The system computes shape indicators and provides volumetric estimates of the edifice (and, when present, of the caldera) through geometric models, making the process more transparent and reproducible. The architecture is based on three main components: a user interface developed with the JavaScript framework React for uploading and managing data through the browser; an orchestration service built on Node.js and the Express framework; and a processing pipeline written in Python, executed in non-interactive mode and based on libraries for raster data handling and scientific computation, with an optional web...
