How to create WMTS service with geoserver and view in openlayer from geotiff? - openlayers-3

I have created a layer in GeoServer from GeoTIFF.It is available in layer preview pane also viewable in Openlayer from the option below.

You likely already have the WMTS for it, assuming you have the "tile caching" enabled in the layer definition panel.
Go to the WMTS capabilities document and you'll find it.
GeoServer does not offer a WMTS based layer preview, but you can code one using the OpenLayers documentation examples:

Is there a way of displaying the Yandex panorama coverage layer on a normal Yandex map?

I'm making a two panel web app with a map and panorama with Yandex Maps API and I need to toggle the panorama coverage layer on the map.
Are there ways of showing and removing the panorama coverage layer without using the default map type drop down menu on Yandex Maps API?

How to add tiles layer on map using MapBox in Swift (iOS mobile app)

I want to set WMS tiles layer on the map using MapBox in my iPhone app.
Note: I am able to add tiles layer at Google Map using provided methods at https://developers.google.com/maps/documentation/ios-sdk/tiles.
Now I am trying to add WMS tiles layer in MapBox but I am not able to get any method to add WMS tiles layer at the map.
If there is any way to set tiles layer in MapBox. Please let me know.
Thanks in advance.
I recently had need of this for a project myself, and found this to be a very poorly documented part of the Mapbox iOS SDK. Have a look over on this page: https://github.com/mapbox/mapbox-gl-native/blob/master/platform/ios/docs/guides/Tile%20URL%20Templates.md.
You can use {bbox-epsg-3857} as a placeholder in your URL templates. The rest of the URL format will be all your standard WMS junk like version, request, format, etc. For the WIDTH and HEIGHT, use 256.

Difference between TileWMS and WMTS in openlayers 3?

Whats the difference between ol.source.TileWMS and ol.source.WMTS? As of i know if tiled = true is added in WMS url both will return Tiled Images in openlayers 3.
Thanks in advance.
The OpenLayers documentation says:
An ol.source.TileWMS loads tile data from WMS servers.
An ol.source.WMTS loads tile data from WMTS servers.
A WMS serves images which are generated on-the-fly, whilst a WMTS serves tiles which are pre-rendered and cached.
The advantage of the latter is that you achieve better performance, but it also requires storage space.

Does Open Layer 3 not support offline map?

We are going to display a map (with custom tiles overlays) in a webview on mobile device, when there are no connections, we had to support loading low-res version of the map (with custom tiles overlays) from the device. while open layer 2 does have some examples about it. We can't found any with open layer 3. We would like to know more on it, so it would not too late to take any alternative solutions.

On which OSI layer image stegnography is done/handled

I want to know on which OSI layer image steganography is done with explanations about why it is on that layer. I have tried searching for this everywhere but it was of no use.
If you are embedding data into your image then it means you are working in presentation layer of OSI model.I got this answer from the link posted above in comments
