cdemgl

Tool that creates glTF model from CDEM raster grid.

Elevation source: CDEM FTP

Imagery source: sat-api

Install

pip install -r requirements.txt

pip install -e .

Environment Variables

download_dir: root directory that will hold raw CDEM data
outputs_dir: root directory that will store outputs (intermediate and final model)

export download_dir='/path/for/cdem/data'

export outputs_dir='/path/for/outputs'

Usage

Usage: main.py [OPTIONS]

Options:
  --coords <FLOAT FLOAT>...       Longitude <space> Latitude  [default: None,
                                  None]

  --zfactor FLOAT                 Elevation stretch factor  [default: 1.0]
  --outsize INTEGER               Square output size, in pixels  [default:
                                  1000]

  --output TEXT                   Output format: gltf|glb  [default: glb]
  --install-completion [bash|zsh|fish|powershell|pwsh]
                                  Install completion for the specified shell.
  --show-completion [bash|zsh|fish|powershell|pwsh]

  --help                          Show this message and exit.

Outputs

<outputs_dir>/intermediate: various geographic/projected DEMs and images
<outputs_dir>/model: gltf/bin or glb model, html viewer for model
