S57 display

ModyBuchbinder — Mon, 21 Jan 2013 04:40:47 GMT

Hi all

I am trying to display a S57 file in the new RunTime WPF SDK 10.1.1
The example for HydrographicS57Layer is clear and works fine.
Now I would like to control my display properties (for example NIGHT color scheme).
As far as I understand I need the HydrographicS52DisplayProperties class for this.
I cannot find the way to get HydrographicS52DisplayProperties from HydrographicS57Layer.
The HydrographicS57Layer is written in the HydrographicS52DisplayProperties help (see here: http://resources.arcgis.com/en/help/runtime-wpf/apiref/ESRI.ArcGIS.Client~ESRI.ArcGIS.Client.AdvancedSymbology.HydrographicS52DisplayProperties.html ).

Thanks
Mody

Try the following:

HydrographicS52DisplayProperties a = HydrographicS52DisplayProperties.Default;
a.ColorScheme = S52ColorScheme.DayWhiteBack ;
hydrographicS57Layer.Cells.Add(cell);

Hi folks,

I've got the same issue with .NET SDK 10.2.4. I'm able to create HydrographicS57Layer with the default color scheme. But I can't figure out how to apply HydrographicS52DisplayProperties. Neither the HydrographicS57Layer nor the MapView or Map have appropriate Properties to set. Any help would be highly appreciated.

Eugen

private HydrographicS57Layer CreateENCLayer(string pathToENC)

{

HydrographicS57Layer hydroLayer = new HydrographicS57Layer()

{

Path = pathToENC

};

HydrographicS52DisplayProperties displayProperties = HydrographicS52DisplayProperties.Default;

displayProperties.ColorScheme = S52ColorScheme.DayWhiteBack;

return hydroLayer;

}

Eugen, have you checked the DisplayProperties sample on ArcGIS Runtime for .NET Samples?

Edit:

You should be able just to set values to HydrographicS52DisplayProperties.Default instance and those should be reflected to the map. If you see issues with this, could you provide a repro application so I could have a look?

In future, please use ArcGIS Runtime SDK for .NET‌ place for .NET specific questions.

Hi Antti,

I've checked the sample you mentioned. I didn't know that I need to set the DataContext of the MapView to HydrographicS52DisplayProperties. Now it works fine.

Thanks a lot!

For those who are interested:

HydrographicS52DisplayProperties displayProperties = HydrographicS52DisplayProperties.Default;

displayProperties.ColorScheme = S52ColorScheme.DayBright;

displayProperties.DisplayDepthUnits = S52DisplayDepthUnits.Meters;

MainMapView.DataContext = displayProperties;

You shouldn't need to add it to DataContext. In sample it is used because it is manipulated through DataBinding.

Alright, got it.

I'm also displaying bENC with soundings. I was wondering if I can filter these soundings, because I don't need them. I already tried to change Text- und ViewGroupProperties to see if anything happens. But my ENCs and bENCs still look the same.

I'm not expert on hydrographic terminology but you should be able to define if soundings are shown using

HydrographicS52DisplayProperties.Default.ViewGroupProperties.Soundings = false;

I already tried that one, but unfortunately it didn't work. Any other ideas?

You could load your data to S57DisplayPropertiesSample and see what settings does the trick.

Hi Antti,

that was a very good hint, thanks a lot!

I'm able to load my data into the example. When I check and uncheck the soundings checkbox the soundings appear and disappear from the map. However, when I try to disable soundings programmatically at start up, they just don't disappear. This is how I disable soundings:

public S57DisplayPropertiesSample()

{

InitializeComponent();

// Create default instance of display properties and set that to DataContext for binding

DataContext = HydrographicS52DisplayProperties.Default;

HydrographicS52DisplayProperties.Default.ViewGroupProperties.Soundings = false;

ZoomToHydrographicLayers();

}

Is this a matter of timing or something else?

Hi Antti,

I could sort this problem out myself. It was really a matter of timing. I had to change the display properties after all Layers were loaded:

public S57DisplayPropertiesSample()

{

InitializeComponent();

// Create default instance of display properties and set that to DataContext for binding

DataContext = HydrographicS52DisplayProperties.Default;

ZoomToHydrographicLayers();

}

// Zoom to combined extent of the group layer that contains all hydrographic layers

private async void ZoomToHydrographicLayers()

{

try

{

// wait until all layers are loaded

await MyMapView.LayersLoadedAsync();

HydrographicS52DisplayProperties.Default.ViewGroupProperties.Soundings = false;

...

Thanks for your help again!
