survex.js

Dependencies

• survex: 1.4.1
• emsdk: 3.1.0. This defaults to node 14.15.5 and npm 6.14.11.

Development

1. Run source ./build.sh init-emsdk to initialize the environment before doing any other dev work. source is required to update the PATH in the current shell
2. Run git submodule update --init to fetch src/survex
3. In build.sh, see build for building wasm files or package for building webpack files

Example

• Only works as a proper NPM module (no browser support, PRs accepted :))

const survex = require('survex.js');

survex.load((Survex) => {
  Survex.imgOpen('http://10.42.0.203:8081/svn/skydusky/us/va/bland/Skydusky/Skydusky.3d')
  .then(img => {
    while (img.code >= 0) {
      if (img.code === survex.codes['raw']['img_LABEL']) {
        console.log(`label: ${img.label}, X: ${img.mv.x}, Y: ${img.mv.y}, Z: ${img.mv.z}`);
      }
      img = Survex.imgReadItem(img.ptr);
    }
  });
});
