Support for WMTS

Hi.

Does Microstation support for WMTS? http://en.wikipedia.org/wiki/Web_Map_Tile_Service

I can get WMS to work, put not the WMTS.

    Hi Stian,

    Since WMS server doesn't provide information about their tiling strategy or the different resolution factor of their data it is very hard to cache correctly the data while providing the same results as if the data was always directly queried from the server, which is why we do not cache WMS data. Also I think there is legal issue regarding physically caching the WMS data so that the WMS server doesn't need to be access.

    For those reasons we almost always query the data from the server, though we do have some RAM caching when new WMS data is requested at the same resolution (i.e. : panning).

    HTH,

    Is it possible to disable this WMS caching in RAM? It acts weird in v8i and CONNECT editions. At some zoom levels it doesn't refresh view and shows low resolution and correct resolution image at the same time. It is most noticable for WMS which have lines only. Also as there are no indication if request is finished users are confused when it is actually loaded.

    Hi Otto,

    The caching has been there for many years, my guess is more the WMS server is doing weird things (we have seen that quite often).

    Have you tried with different WMS server to see if it occurs with all servers?

    Thanks,

    Mathieu

    It is weird WMS server named Bentley Geo web publisher it has been weird for many years :)

    Regarding the WMS caching in MS there seem to be issues with refreshing the view starting from SS3. It doesn't seem to be related to server as there are no issues in other WMS clients and also in v8i SS1 it works much better. See attached example(not from GWP server). Borders are not correctly shown when zooming in and out.

    Hi,

    The refresh problem you are mentioning is because the WMS server you are using seems very slow, so until we have the correct data from the server we are displaying the resolution of the data we already have, allowing the display to not freeze. If you want to go back to the old display just check out the Use Independent.... parameter below.

    HTH,

    Mathieu
