I need to get all my layers in the EPSG:4326 (WGS84) reference system. I thought I knew how to define projections but I guess not, because when I do so, the layer ends up way far away from the other layers. Someone before said it's because my layer Extent was messed up and that it needs to be between -180 and 180. The problem layers all have Extent values in the 6-7 digit range. How do I fix this?
