Hello Toprak Abdullah,
Please, take a look into the following example in our demo application:
It looks similar to the one you've referenced. It uses ESRI shape files to represent hotel floor plan and objects on it.
There are several tools on the market which allow creation and editing of ESRI shape files (ArcGIS, MapWindow GIS and so on). Some of them are quite expensive, some are free. Review of these tools is outside of the scope of RadMap support, you can find all the information you need in the Internet.
Implementation of the scenario when floor plan is represented by image is simple, because you would not need to create ESRI shape files. You can show floor plan using UriImageProvider and then put some map shapes (MapPolyline, MapPolygon, MapPath and so on) over it. But it is less functional, because you will not be able to select rooms on the floor plan, but map shapes only.
Another problem is serialization/deserialization of the map shapes that are shown over the map. RadMap does not have a built in functionality for this, so you have to create it by yourself.
