I realize this isn't a geographic question as I'm not trying to make this into a geographically placed image. But I hope you all will know how to do this.
I want to make a raster from scratch. I have a database that I would like to be able to query and display the results as a sort of color map. I can figure out how to do the math and raster calculating, but I can't figure out how to make a raster. I expect that I need to add a couple of fields for the x and y coordinates, then give each record a value. Just 1s and 0s to begin with.
I work with ArcGIS, Oasis Montaj, and Microsoft Access at work all day, but I'd like to do this in QGIS and whatever other tools are necessary. I have spent almost no time with QGIS but would like to learn and work with it on my own projects. But I need to point in the right direction for this one.
