Hi! I have to make contours for bathymetry that I am working with. Unfortunately, I only have a .tif raster being displayed using bands...When I use the contour tool it creates contours based on the shading of the image instead of elevation. Does anyone no if it's possible to create contours based on elevation using this type of raster or insight on what I should do instead? I have attached an image of what the contours look like on my .tif raster. Thank you!
