Ok here's the page that will help you map any two geo-referenced rasters side by side and fade them over satellite view etc:
https://answerquest.github.io/overlap-custom-side.html Screenshot: <https://i.imgur.com/9ccbMSG.png> By the way, in case you have done the geo-referencing on QGIS / ArcGIS and have a big GeoTIFF sitting on your laptop and don't know how to put it on the web, 1. Login to Mapbox Studio 2. Upload the GeoTIFF file as a dataset. Note the id. 3. Note your mapbox accesstoken. 4. Construct the tile URL as follows: "https://a.tiles.mapbox.com/v4/" + mapboxID + "/{z}/{x}/{y}.png?access_token=" + accesstoken 5. Paste in the Left or Right textbox in the above page.
