Hi Andra,

very right, the data for background maps originates from the OpenStreetMap, both at WDQS and Wikipedia (if you check the map of Suriname by clicking the coordinates in the heading of its WP page, you can see, that the Tigri Area is part of Guyana).

I've just checked the OSM data in that area and the map is de facto blind there. There are only the main rivers and the state borderline with "source=CIA World Database II" listed.

As I checked other disputed territories elsewhere, it is technically possible to draw a disputed state border in OSM, but first of all, you need some trustworthy source from which you can redraw the boundary.

Best way how to fix this would be to contact local OSM community (if exists) and let them check it.

Regards

 Jan

(not 100% sure) The problem doesn't come from WDQS itself but from OSM and it should be corrected there (if possible, I don't know exactly how OSM deals with such complexe problematic).
