NDVI Viewer

Allows the analysis of NDVI over time for a region using regl, WebGL, and React. (Live Demo)

Note: this is alpha software and requires more documentation and tests before being generally useful.

Running the project

To run the project, you'll need:

  • Node 9+
  • a recent version of Yarn
  • git-lfs
  • ogr2ogr

Then:

  • Clone this repo, and run yarn to install dependencies
  • Run bash scripts/make-vectors.sh to download and process geojson for Iceland
  • Run yarn start to start a development server
  • The app should be available at http://localhost:8080 (initial page load will take a while for compilation)

Data format

The main data file, src/assets/atlas/ndvi.atlas, was produced using geotiff-atlas. Refer to the README of that repository for more information.

Focus on Iceland data set

For now, this viewer is focused on Iceland, to make it work with another region some changes and enhancements would need to be made:
