I knew this would happen ;) Yes, merging a large set of polygons is slow. If you want to implement a "realtime" interactive merging, the simple incremental merge will fail performance-wise. map&market uses a special algorithm for merging base polygons. It's called "FastUnion"...

@Bernd hinted me a method which should be better:

NTS has a dedicated function

Didn't know this exists, havent used it much lately.

Mea culpa

Short answer:

You can do this with NetTopologySuite, which is part of SharpMap. The solution is to put all polygons into a GeometryCollection and create a Buffer() with size 0. This gives the desired result.

Sorry, the answer maybe too short. Don't have code for it at hand,

Hi Rok, this seems to be a problem with the xsd.exe tool in combination with the XmlSerializer class. xsd.exe creates the property with a DefaultValueAttribute set to EURO_5, and the XmlSerializer doesn't write a value if it's equal to the default value. A workaround for this issue is to remove the ...

Hi Javor, Though there are two options for the WPF-Control. You can test them at https://github.com/ptv-logistics/xservernet-bin. 1. You can make the Tile-Layer semi-opaque and set the background of the control to black (sample CustomLayout). Dimmer.png 2. Use the control with xServer-2. xMapServer-...

Hello Alex, i must say this is not that simple out-of-the-box. It requires a layer-configuration which returns multiple language fields. This is not supported by the default configration of the TrafficInformation layer. However, there's an alternative "map&guide-internet" TrafficInfoLa...

Hi Prarakash, think this isn't a possible with the ajax control out-of-the-box. It seems you need some GIS methods for your task, i.e. intersect your polygon (which is a convex hull?) with the polygon of the country border. This means you also need those country borders as polygons plus a geometric ...

Hi, some customers have reported issues with the xServer.NET FormMap control and HighDPI displays. Whenever the Map is displayed, the complete application gets scaled weirdly. I've digged into this issue and found that this can be reproduced simply by adding the Standard WinForms ElementHost-Control...

We don't support dedicated Leaflet-Clients for Leaflet > 0.7 If you are using Leaflet with xMap-1, we recommend using the WMS/Tile-Servlet, see https://github.com/ptv-logistics/xserverjs/tree/master/boilerplate/xmap-1 If you need extended Layers, take a look at https://github.com/ptv-logistics/Leafl...
