Precise Elevation vs. Free: Comparing Elevations from Total Station and Digital Elevation Models
• Introduction to Elevation Data: Understand the difference accuracy of elevation data for site planning and WASH (Water, Sanitation, and Hygiene) projects, particularly in regions with limited access to precise measurement tools.
• DEM Sources Compared:
- FabDEM
- SRTM
- NextMap
- ASTER GDEM
- ETOPO1
• Comparison Methodology: The analysis focuses on calculating the standard deviation of differences to determine accuracy.
• Results and Practical Demonstrations: Discover the comparative results, with visual demonstrations showing the accuracy differences. FabDEM stands out as the model providing the most reliable results.
• Implications for Site Planners and WASH Professionals: Gain insights into how these findings can guide site planners and WASH professionals in choosing the best available DEM for their projects when precise tools like total stations are not accessible.
• Conclusion: We summarize our findings, emphasizing the superior performance of FabDEM and providing recommendations for professionals in the field.
Who Should Watch:
- Site planners and engineers
- WASH professionals
- Students and educators in geospatial sciences
- Anyone working with elevation data in resource-limited settings

While I strive to provide educational content, explaining the science behind hydraulic modeling in depth would require a more comprehensive approach than I can provide in a brief response. I encourage you to continue exploring the topic through reputable resources and perhaps seek guidance from a qualified instructor or expert in the field. Keep up the enthusiasm for learning, and I wish you the best in your endeavors.

      Normally, a drone should orient itself and per default it uses the geographic coordinates. When you develop the orthophoto or the DEM, you can choose the local coordinate system. If you forget it, you can re-project into Local Coordinate system, e.g. UTM, using any GIS software (qGis or Global Mapper, for example)
