Hello Jai,

In order to render imagery in Cesium, you have to convert it to a tiled format. You can learn about the different imagery provider formats we support here: http://cesiumjs.org/tutorials/Imagery-Layers-Tutorial/

I believe you can convert your GeoTIFF into tiles using gdal2tiles. This should break it up and tile it in a TMS format, which you can add to Cesium using createTileMapServiceImageryProvider

Best,

Hello Jai,

we also use gdal2tiles to show raster data in cesium.

var url = urltoTMS;

var format = png;

var maxZoom = 19;

var minZoom = 10;

var extent = [7.66741440820387, 51.56955904736495, 8.00795370918629, 51.74818086839236];

var imageryProvider = Cesium.createTileMapServiceImageryProvider({

“url” : url,

“fileExtension”: format,

“maximumLevel”: maxZoom,

“minimumLevel” : minZoom,

“rectangle”:Cesium.Rectangle.fromDegrees(extent[0], extent[1], extent[2], extent[3]),

“show”:true

});

var imageryLayer = new Cesium.ImageryLayer(imageryProvider);

This is an example code we use, maybe this will help.
