Backstory: employer is GIS incapable and most of the data we work with doesnt play nice with GIS software. That said, we have a client who is very GIS oriented. My boss (not my work) is providing them with what are really just pictures of an environmental variable that he creates in photoshop. They are asking for the "world file" for the rasters so they can plug the images into their ESRI powered dataflow.
I have georeferenced the rasters before to make some overlays, but I believe they are currently referenced to NAD (it's the Gulf of Mexico-NAD worked).
I have seen some guide info online for generating world files, projection files, etc with QGIS but wanted to ask the community's opinion on how to make the simplest, most compatible solution? w
ould it be the '.wld' extension I've seen or do i need the projection '.prj' file?
Do I need to find out the clients projection since they are likely on a more global coordinate system than the NAD?
