Performing a geodetic survey of the scarp of the river Vrbas involves conducting precise measurements and mapping of the area to gather geospatial data. This data can be used for various purposes such as topographic mapping, land management, engineering projects, and environmental assessments.

Here are the steps involved in conducting a geodetic survey:

1. Define the survey objectives: Clearly outline the goals of your survey. Determine the specific information you need to collect, such as elevation data, slope measurements, or ground control points for mapping purposes.

2. Plan the survey area: Identify the extent of the scarp of the river Vrbas that you want to survey. Consider the size of the area, accessibility, and any specific features or points of interest that need to be included in the survey.

3. Select surveying methods: Geodetic surveys can be conducted using various methods, depending on the accuracy required and the available resources. Common techniques include:

4. Ground-based surveying: Traditional surveying methods involve using total stations, GPS receivers, and leveling equipment to measure points on the ground. This can provide accurate elevation data and establish control points.

5. LiDAR (Light Detection and Ranging): LiDAR technology uses laser pulses to measure distances and create highly detailed point cloud data. It is particularly useful for capturing the topography of the scarp and surrounding areas.

6. Aerial surveying: Utilizing aerial platforms like drones or aircraft equipped with LiDAR or photogrammetry systems can provide detailed and high-resolution data over larger areas.

7. Conduct the survey: Implement your chosen surveying methods to collect the required data. Follow established surveying procedures, including setting up control points, taking measurements, and ensuring proper calibration of equipment. Collect data at regular intervals along the scarp to capture its variations and characteristics accurately.

8. Post-processing and data analysis: Once the field survey is complete, process the collected data using specialized software. This involves adjusting measurements, removing errors, and creating digital elevation models (DEMs), point clouds, or other relevant outputs. Analyze the data to extract the desired information, such as slope profiles, contour maps, or cross-sections.

9. Interpretation and visualization: Interpret the survey results to gain insights into the scarp of the river Vrbas. Use software tools to visualize the data and generate maps, 3D models, or other representations that effectively communicate the topography and characteristics of the area.

On the field, we used SinoGNSS T30 GNSS receiver to perform geodetic survey.

About SinoGNSS T30 receiver: Featuring full-constellation tracking capability, tilt compensation, 4G/Wi-Fi/Bluetooth® connection, and easy survey workflow with Android-based Survey Master Software, the T30 GNSS receiver is one of the most reliable choices for your demanding surveying tasks. Collect more accurate data easier and faster no matter for beginners or professional surveyors. Its built-in tilt sensor supports maximum 30 degrees pole tilt, and you can check electronic bubble on the controller for fast survey in the field. Moreover, the T30 GNSS receiver supports L-band frequency and PPP service. With PPP function it can works without any base to get centimeter accuracy results which gives more flexibility for different surveying tasks.

Work procedure:

1. We went out to the field to tour the field and see what needs to be done.

2. In the office, we made a plan for the shoot, including a list of the equipment we would use.

3. We went to the field and did the surveying. There was one team on the field, one person worked with the instrument, and the other led the sketch.

4. When we returned to the office, we processed the data and made a geodetic survey of the recorded terrain.
