Sulawesi bump map images for download
The image layers
Right click on the images and choose 'Save as' for all six.
- 1. border layer
- 2. land layer
- 3. sea layer
- 4. duplicated land layer filled white
- 5. blurred bump map datum layer
- 6. bump mapped land layer
Note:
The blurred bumpmap (Image 5) was saved as a .png to preserve the blurring. In IE the transparent background shows as white. Persevere with IE and trust me or change to Firefox/Opera and see what I'm seeing
