I am trying to export the basemap in ArcMap to use it with my mosaic dataset. I need these 2 to import and work with in Unity 3D.

When I am exporting my mosaic dataset consisting of DEM files, I can right click on the dataset and click export. There I have the option to "use renderer" and "square", together with choosing to use either entire mosaic or current view dataset.

However, from what I can notice, the only way to export the basemap is to click file - export.

What is the problem:

  • I need the exported DEM to match with the basemap when I export them as .png.
  • If the exported basemap is different (different size/pixels) the basemap which is used as a projection over the imported DEM will not match (for example the sea will be projected into the mountainous region of my DEM)

Could anyone help me match these 2?

I do use photoshop to edit my DEM/basemap for importing into Unity (16bit, grayscale for DEM, etc).

Maybe is it possible to photoshop the exported basemap to match with my DEM?

You should be able to Export Map to export a PNG file with a world file.

The trick is to be in Data View when you do this.

See Problem: When exporting to BMP, JPEG, TIFF, PNG and GIF from ArcMap, 'Write World File' is grayed out.
