2. Click the "Open ..." button, a dialog box appears.

3. Select "Remote Sensing" from the "Main category list", select "Elevation - True color" from the "Sub category list" and click OK, a window opens to display image.

Examine Data by Pixel

4. Click the Image Pixel button.

5. Move your cursor to any point of interest on the image, the "Image Pixel" dashboard appearing at the lower right corner of the image window displays the elevation data value for the current pixel.

Apply Visual Data Filters

6. Choose a pixel of moderate elevation with respect to its surroundings.

7. Right-click the target pixel, a pop-up menu appears.

8. Select "Image Filter On", an "Image Filter" dialog box appears.

9. Choose "Interpreted Elevation (m)" from the "Analysis by" section, "Above" from "Select target range", "No filter" from "Luminosity filter", and "Highlight target area" from "Filter display style", then click OK, all pixels of elevations greater than your target will be highlighted to a transparent color.

10. Right-click the image again and select "Image Filter Off".

View 3D Elevation Plots

11. Continuing at this image level, locate a region of interest. Right-click for 3D visualization and a pop-up menu appears.

12. Select "Image 3D Study", a dialog box appears for you to choose between two 3D modes "Quick browse" and "High quality".

13. Select "Quick browse" and click OK. A new window appears to display an interactive 3D plot of the target region.

14. Position your cursor over the source image, drag with the right mouse button to refresh the 3D plot with data from a new location.

15. Right click on the source image and choose "Image 3D Study" again, this time select "High quality" mode.

16. Position your cursor over the 3D image, drag with the left mouse button to alter viewing angle.

19. Right-click over the 3D image and choose "Select 3D Options" , the "Select 3D options" dialog box appears.

20. Select "False color" and OK to have elevations represented by a color sequence. A localized false color scheme will be applied to the plotted region, which dynamically maps the span of local elevation values across the entire false color set, to effectively illustrate elevation patterns even in flatter areas.

21. You can make other changes in the 3D display options to meet your requirement. For example, select 3 in the "Surface color smoothing coefficient" drop down box to improve visualization smoothness.

Export Elevation Data

22. Right-click over the 3D image and choose "Data Export", the "Export Elevation Data Options" dialog box appears.

23. Select "Tab delimited" and keep "Include header information" checked, and click OK.

24. Click OK again in the Message box.

25. Open a new Excel file and select "Paste" from the "Edit" menu to obtain elevation data for your current 3D plot.

Add User Notes

26. Close the 3D visualization window, and maximize the source image.

27. From the tools menu, select "Set User Note".

28. Place your cursor over a location you might wish to revisit and left click, a dialog box appears.

29. Enter a label for this location in the "Note index" field, and some comments in the "Note" field, then click OK. Your note will be added with a marker and the label you specified on the image.
