Display hillshade raster using Deck.gl

[lawrencenika]

is it achievable? I m using titiler's /cog/tiles endpoint with algorithm=hillshade and deckgl/react in which tilelayer fetches each image and rendersublayer with bitmaplayer.

If the hillshading is done by titiler it should just work as the served images will already be shaded? If not your problem is probably not with the hillshader,

[lawrencenika]

if the image is already shaded, in that case. should I use TerrainLayer or BitmapLayer?

I tried with TerrraiLayer with the shaded image tile url as elevationData while leaving texture empty, it then shows weird cubes:

Using BitmapLayer before this shows line grids which also seems wrong:

Which approach should I dive deeper into?

You should use the BitmapLayer unless you also have a proper elevatation data source. You may want to check what format titiler is sending, you can do this e.g. in the network tab.

@kylebarron may have some advice.

I assume it's sending back image tiles, in which case you should use BitmapLayer as @ibgreen suggested

Thanks both, when i used bitmaplayer, it shows grids why would that be the case?

It's probably an issue with your input data that you're passing to titiler
