I have a png file which I created from a field equation. I need to plot that on my map. I am plotting it on a map with Coordinate System being GCS WGS 1984 (EPSG: 4326).

Since it is not georeferenced, the image comes in with the top left corner at N 0 E 0, which I anticipated. It also comes in with pixel size at 1 degree. I need to affine transform it by specific numbers, and not by clicking control points.

I have looked around online for a way to do this, but I can't find anything. Can someone point me in the right direction?

If necessary, I can do this in ArcGIS Desktop 10 then move it to ArcGIS Pro.

You'll want to use the translation, rotation, and scale tools to transform the data manually. For translation use the "shift" tool, for rotation use "Rotate" and for scaling use "rescale".

    That does it. It takes multiple iterations because it seems like it is getting confused on the rotation point location, so I have to shift it again after I rotate it. But the main thing is, it works.

  • Also, the information Pop-up is not aware of the rotation. I mention this in case anyone from ESRI happens to notice. This is based on the layer only. I plan to export the layer to a new raster, and I expect that will provide correct info which clicked upon. (But I haven't done that yet.)
