Are there any software/libraries I could reuse for this task? The map should look like an indoor office + layer of labeled points. Layer of labeled points will be provided by already existing code. Possibly capable of working offline.
It can be either a separate tool with API/plugin support or library I could embed in my application.
For now there are no other requirements.
P.S. I already have an existing application that will be a data provider and it is written in WPF.
