Setting map zoom levels to match WMS levels to avoid streaching

  • 1.  Setting map zoom levels to match WMS levels to avoid streaching

    Hi All,

    I am trying to add the Vicmap WMS base map to SSA. However the text and lines in the base map are blurred. Apparently this is caused by SSA distorting the tiles from the WMS to match the displayed map scale.

    https://www2.delwp.vic.gov.au/maps/maps-and-services/vicmap-api/developers/projections-and-scales

    Is there a way to manually input the correct scales at each zoom level? Or do you need to specify the correct extents for SSA to align its zoom levels with the WMS? If the latter is the case do you have any method for determining these extents other than trial and error?

    Kind regards,

    Nevermind. I found that the projection of the map project needs to match the WMS, then some simple tweaking of the extents has produced some good results.
