- Step 1: create basemap:
- I suggest GeoJSON.io.
- Use the polygon tool to draw the regions.
- IMPORTANT: For each region, give a regionID (from 0 onwards) and a name value.
- Save the file as geoJSON.
- Step 2: Importing basemap:
- Scroll down on the right side panel of the app until you see the geoJSON loader panel
- Click to upload or drag and drop the created geoJSON via loader panel
- Step 3: Enjoy!
- IMPORTANT: To save and load your timeline with custom basemaps:
- Save as with a normal map
- Loading using the geoJSON loader panel, the same one you used to load the geoJSON basemap (not the normal load button)
