  • Jagged overlapping contour lines instead of smooth natural curves

    You could do something similar in Global Mapper with a custom slope shader using the equivalent degrees.

  • Jagged overlapping contour lines instead of smooth natural curves

    You can smooth the contours after they have been generated.

    1. Select them with the Digitizer Tool
    2. Right-click > Move/Reshape Feature(s) > Resample/Split Selected Features(s) at Specified Spacing
    3. Choose Sample Features at Fixed Distance Interval
    4. Enter the Spacing Distance e.g. 5 or 10 meters
    5. With the contours still selected Right-click > Move/Reshape Feature(s) > Smooth
    There are lots of ways of exporting the 3D terrain. Can you let us know what you intend to use the terrain for so we can best advise you?

    By the way if you want to clip the SRTM to your boundary you can select the boundary be fore you select the online data source and choose the option at the bottom to Download Within the Currently Selected Polygon(s).

    I think your problem may lie in your simplification settings. Try reducing the simplification via the Simplification tab.

  • add slope in v21?

    1. Select the feature with the Digitizer Tool
    2. Move/Reshape Feature(s) > Adjust Elevations to a Single Slope
    3. Yes
    4. Enter slope value
    5. OK

  • 3D distance instant measure

    You can add 3D distance attributes to selected lines using Analysis/Measurement > Calculate Elevation/Slope Stats for Selected Feature(s) and choosing NO - Sample Terrain Along Path to get the 3D distance data from your terrain . Once added you can use the Feature Info Tool to get 3D distances or view the data via the Attribute Editor.
