Terrain2STL

A web-based service that converts publicly available HGT files to useful STL files.

###To-Do List

• Make dataset voids not just a fixed negative value.
• Make models watertight.
• Increase maximum box size.
• Fill voids in dataset.
• Make the 3 arcsecond resolution available in all sizes.
• Add ability to cross tiles.

###Descriptions of Files

• /hgt_files

  • This directory contains some sample HGT files for testing. Included are Mt. Everest; Rockport, Maine; and San Franciso Bay.
  • The whole dataset is 40GB, so only a few files are included.

• elevstl.cpp

  • This is the source code for the part of the program that actually creates the STL files. Accepts command-line arguments

• gmaps-gridlines.js

  • This script provides the gridlines for the map. It is a slightly modified version of a package found here: https://github.com/alexcheng1982/google-maps-gridlines

• terrain2stl.html

  • The HTML source of the website.

• terrainServer.js

  • Node.js server. Takes parameters from the HTML page and passes them to elevstl to create the STL.
  • Also handles client downloading of pages and files.
