The Projection Browser Dialogue represents the supported projections in a tree view. By selecting an item in the tree the projection definition will automatically be assigned to the Map or Layer from where the Projection Browser Dialogue has been invoked.
The projections have been categorised according to the contents of the proj4 EPSG file. The geographic coordinate systems (like WGS84) are located within the 'Longitude-Latitude' category.
The Projection Browser Dialogue provides the option to search the projections by name or EPSG code. The search term should be added to the 'Name/EPSG' text-box and by clicking on the 'Find Next' button the next projection containing the specified word will be selected.
