 title: WMTS Tile Transitions
 shortdesc: Example of smooth tile transitions when changing the dimension of a WMTS layer.
 docs: >
-  Demonstrates smooth reloading of layers when changing a dimension continuously. The demonstration layer is a global sea-level computation (flooding computation from <a href="http://scalgo.com">SCALGO</a>, underlying data from <a href="http://www.cgiar-csi.org/data/srtm-90m-digital-elevation-database-v4-1">CGIAR-CSI SRTM</a>) where cells that are flooded if the sea-level rises to more than <em>x</em> m are colored blue. The user selects the sea-level dimension using a slider.
