Dynamic Parameters for S-63 charts in Runtime SDK for Qt (QML)

[TiakiRice]

Hello,

My setup currently is:

• ArcGIS Enterprise server with the Maritime Chart Service enabled
• S-63 charts properly licenced and set up with a permit
• Qt QML project being developed on a machine co-located with the chart server

I can load the charts just fine using an ArcGISMapImageLayer pointing at the "http://..../MapServer/exts/MaritimeChartService/MapServer" url of my chart server.

My question is: how do i set the Dynamic Parameters of the S-63 charts; specifically the Colour Scheme. I see there is an ENCLayer with mariner options which i don't think I can use with S-63 charts as they must be hosted on a chart server. From what I can gather I need to pass in display_params somehow to the export requests being made to the server. I'm just not sure where i would add these parameters.

Current code below (practically sample code at this point):

ApplicationWindow {
    id: appWindow
    width: 800
    height: 600
    title: "Project"

    MapView {
        anchors.fill: parent
        focus: true

        Map {
            Basemap {
                ArcGISMapImageLayer {
                    url: "http://127.0.0.1:6080/arcgis/rest/services/TiledMap/MapServer/exts/MaritimeChartService/MapServer"

                }
            }
        }
    }
}‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Cheers, Tiaki

Hi Tiaki Rice‌,

   I initially responded incorrectly. Let me do some research on this and get back to you.

[JamesBallard1]

Unfortunately I don't think there is any way to do this. You'd need to add custom query parameters on the rest requests on there is no way to do that.

I will check with my colleagues to be sure.

[TiakiRice]

That would be quite disappointing if that is the case. It is strange that this isn't possible as having a look at the WMS Layer class, it provides a "customParameters" field which allows exactly that.

Why is this same functionality not available for the ArcGISMapImageLayer class?

Tiaki Rice‌,

  Thanks for your patience. I've checked with some colleagues and we are considering a new feature in an upcoming release that will accommodate setting custom query parameters per-layer. It's being considered for a post-100.7 release, but I cannot make any guarantees about when it will be available.

We do hear your concerns and hope to get this implemented.

Tiaki Rice‌,

   I found out some more information. It turns out you can publish MCS as a WMS service. The endpoint would be

http://..../MapServer/exts/MaritimeChartService/WMSServer 

If you're able to access the WMS service endpoint, you should be able to consume the layer as a WmsLayer

WmsLayer QML Type | ArcGIS for Developers 

With that, you can use the customParameters as you pointed out before.

WmsLayer QML Type | ArcGIS for Developers 

Please let us know if that works for you.

James,

Thanks for the information! This does get me a little closer although I will say the amount of configuration for a WMS server utilised in this way is pretty woeful.

The specific parameters that i'm trying to configure are the DisplayParameters such as requesting a different "ColorScheme" value. I am aware that these can be changed via the S52DisplayProperties.xml but i need to be able to change these parameters during runtime.

The following JSON reported by "http://127.0.0.1:6080/arcgis/rest/services/service/MapServer/exts/MaritimeChartService/MapServer/par..." shows the parameters which don't appear in the WMS server. 

{
 "DisplayParameters": {
  "ECDISParameters": {
   "version": "10.7.1",
   "DynamicParameters": {
    "Parameter": [
     {
      "name": "AreaSymbolizationType",
      "value": 2
     },
     {
      "name": "AttDesc",
      "value": 1
     },
     {
      "name": "ColorScheme",
      "value": 0
     },
     ...
     ...
     ...
    ]
   }
  }
 }
}‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

James Ballard,

I'm revisiting this issue which I could not manage to resolve at the time with a potential alternate solution.

I'm trying to load S-63 charts using an EncLayer via an EncExchangeSet. All is well until it tries to load the cells at which point I receive the following error: "Cell load error: Cell Permit not found. Load the permit file provided by the data supplier."

Are S-63 charts supported by EncLayer in 100.7.0? If so, how do i load my permit using the EncExchangeSet class? If not, what options do I have to load S-63 charts in ArcGIS Qt runtime SDK 100.7.0 and be able to modify the display properties (i.e. colour scheme) during runtime?

Hi Tiaki Rice‌,

  No, unfortunately S-63 datasets are not supported with the Qt SDK at this time.
