  • Generation of a Digital Elevation Model using high resolution satellite images

    By Mr. Yottanut PaluangFoS: RS&GIS

  • Presentation Outline IntroductionMethodologyResult of this studyConclusion

  • IntroductionDigital elevation models (DEMs) are increasingly used for visual and mathematical analysis of topography, landscapes and landforms as well as modeling of surface processes. This study attempts to find out the quality assessment of DEM products using different satellite images including ASTER and ALOS PRISM stereo image, comparing existing DEM. Three techniques are used to validate the result of DEM products

  • Objectives

    1. To fuse DEM from ASTER and ALOS PRISM satellite imagery.

    2. To evaluate the derived DEM for the suitability in term of terrain surface application.

    3. To verify the result of DEM for several terrain surface in term of application suitability.

  • ALOS PRISM DEMElevation rangeLow: 135 mHigh : 1625m

  • Fused DEMElevation rangeLow: 58 mHigh : 1086 m

  • Methodology ContdObjective 2: To evaluate the derived DEM for suitability of terrain surface application 1. comparison of the drainage network from these DEM

    DEM Verification

    Increment of GCPs

    Increment of Tie Points

    Sink fill, cloud and Shadow and Removing

    2. DEM Evaluation

  • Drainage networks

  • Locational ErrorFirst step: line buffering. Perform a buffer operation on the line data sets X , using a buffer size, , which should be significantly larger than the geometric accuracy measure found for the data set X.

    Second step - overlay. Perform an overlay of the two line-polygon overlays: Overlay X with Q, resulting in the new mixed data sets as XQ.

    Third step: statistics. Statistics is run to determine completeness

  • Methodology ContdObjective 2: To evaluate the derived DEM for suitability of terrain surface application 1. comparison of the drainage network from these DEM2. comparison of the terrain relief and Profile Curvature

    DEM Verification

    Increment of GCPs

    Increment of Tie Points

    Sink fill, cloud and Shadow and Removing

    2. DEM Evaluation

  • Terrain relief & Profile Curvature- Linear error represents the accuracy of the vertical and the horizontal position. - Differences of profile curvature between DEMs are displayed as linear features

  • Methodology ContdObjective 2: To evaluate the derived DEM for suitability of terrain surface application 1. comparison of the drainage network from these DEM2. comparison of the terrain relief and Profile Curvature 3. comparison of the elevation of the derived DEM with the check points

    DEM Verification

    Increment of GCPs

    Increment of Tie Points

    Sink fill, cloud and Shadow and Removing

    2. DEM Evaluation

  • Comparison of the elevation of the derived DEM with the check pointsDefined from the GCPs, Tie points, and user defineAn algorithm of accuracy evaluation called Root Mean Square Error (RMSE)

    Where mz is RMSE of elevation Zi is the elevation differences between the derived DEM and the check points n is the number of check points The lower the RMSE, the better the solution

  • The number of Check Points

  • Comparison of the elevation of the derived DEM with the check points Contd

  • IntroductionMethodologyResult of this studyConclusion Presentation Outline

  • Conclusion - The quality of ALOS PRISM DEM result is fitted to the referenced DEM. The drainage networks of ALOS PRISM are likely fitted to the referenced dataset.ALOS PRISM DEM at finer resolution present more detailed features. Fused data are more useful for the lack of data and the damaging terrain surface.

  • Recommendation for Further researches - Satellite Image should be free cloud for DEM generationThe quality of DEM result depend on the number of GCPs- User must concern the source of data to generate DEM. - Apply to use in other area.
