Overlays are geo-rectified historical/antique maps or statistical data, layered on top of the base map.
At present, creating an overlay takes some work from our team. We are provided with a map – these are usually large scale scans. These are then geo-rectified in a program called MapTiler and exported out as tile sets which are hosted on Amazon S3. Creating an overlay & overlay group in the CMS points to these tiles.
From this dashboard you can edit or delete existing overlays and create new ones.
