 You can change the map projection method between Mercator, and some others. Be aware that projections maybe only valid for a certain area of the world.[[BR]]
-Proposed update (please check):[[BR]]
-Here, "projection" probably means a projection to which OSM data is translated before being displayed on the screen.
-Ticket #5387 comments 7 and 9 state that, unlike other programs, JOSM cannot translate raster projections, only vector.
-Hence, all the raster scan overlays that you use in this case must support the projection that you set here.
-Consequently, either JOSM forces their servers to use that projection or one has to force them manually.
-(I can't say which because I couldn't get projection 3170 working this way)
+The default projection for JOSM is Merkaartor. This projection has certain advantages, one of them is that geometric figures (e.g. circles and rectangles) aren't deformed when displayed.
 
-== Map Paint Styles == #FIXME
+When you use rasterized background imagery then you need to set a projection supported by the service providing this imagery. JOSM is not able to change raster images. When image projection and current settings do not match, you get warned.

+== Map Paint Styles ==

+In this section sources for displaying the data can be changed. Beside the internal styles also externals styles are presented and can be activated.
 
 == Tagging Presets ==
