    Good day
    I am trying to import aerial photographs into RAS mapper (to use instead of Google Satellite), but I cannot get it right. The files are .ecw and geotiff, can someone please advise me on how to get this right?

    Thanks in advance

    What is happening when you try to load them? RAS Mapper rejects them? Nothing is visible? They show in the wrong place?
    What happens if you try to load them in a GIS e.g. QGIS? Do they show in the right location? Does the GIS need to ask you what coordinate system to use for them?
    I haven’t tested whether RAS supports ecw, but geotiff should normally load fine if both it and the project are correctly georeferenced.
