Re: Translate traffic information

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" TrafficInfoLayer that ...

Re: How to display/cover a map area by geo locations

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 ...

FormsMap Control and HighDPI settings

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 ...

Re: Latest version of Leaflet supported by PTV components

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

If you need extended Layers, take a look at

Re: c# example res/json web API ?

My recommendation is JSON.NET (https://www.newtonsoft.com/json). It's some kind of de-facto standard, even Microsoft uses in their projects. But there are many flavors for serializing and deserializing your objects, here are two:

Re: Does PTV provide an ANGULAR2 component for rapid map dev

Hi Bernd,

here's also a nice resource for initializing the xMapServer with

* Different Widgets (Leaflet, OL)
* Different xServers (xMap1, xMap2)
* Different Deployments (xserver-internet, on-premise)

Re: Alternate solution to implement use case "Map and Market

The implementation should be the gold standard for rendering many polygons out-of a database.

I have the same code inside ASP apps, and it renderes several 10k polygons well, you can check the performance here:

Re: How to add the large number of icons in map at once?

Generally that's a tough problem, and there's no simple answer for it. But you can classify the solutions bythese three categories:

This handles the problem by reducing the total count of elements which have to be created. But this may be not appropriate for every use case ...
