The Geo-domain explorer tool helps visualize geo-domains in OpenFLAME. The tool is hosted here. Read the documentation on how to use the tool in the Geo-domain explorer section on the main website.
The webpage is a static page with everything happening in the index.html file at the root of this repository. The map and all its funtionality is handled by assets/main.js. This javascript is generated using webpack and the code is available in the map-js/ directory. Go to the README file within the directory to see how to build the main.js file.
All the S2 cells logic (covering a region with S2 cells, getting the boundaries of an S2 cell, conversion between S2 cell index formats, etc) is handled in the Go code in the s2-region-covere-go/ directory. The Go code is compiled to the wasm file at assets/wasm/region-coverer.wasm. Go to the README file in the directory to see how to compile this wasm file from Go code. The javascript code in map-js/ directory assumes the presence of this wasm file and uses it as a resource.
