It is possible to drape a georeferenced TIF image (or any image type) over a 3D map to view it in 3D, provided the image and the 3D map are in the same coordinates.
- Create the 3D map. Click Home | New Maps | 3D Maps | Surface, select the grid file and click Open.
- Now let’s drape an aerial image over it. Click Home | Add to Map | Layer | Base, select the georeferenced image file and click Open.
- As long as the image and the grid file use the same coordinate system and coordinate units, the image is draped appropriately over the 3D surface. Now you can change the properties of the 3D surface layer to see the draped image a little better. Select the 3D Surface layer in the Contents window.
- In the Properties window, click the General page.
- Click the Custom colormap (...) button to the right of Upper.
- In the Colormap dialog, set the Preset to GrayScale (at the top of the list), and then click the left hand color node and change the color to White (so the colormap goes from white to white).
- Click OK.
- Click the Lighting page, and set the Vertical (degrees) light position to 80. This brightens the map up a bit.
- If desired, you can eliminate any vertical exaggeration by selecting Map in the Contents window and in the Properties window, clicking the Scale tab. Set the Z Scale to match the X and Y scales.
