There are several ways to overcome obstacles in a chain survey:
1. Proper planning: Before starting the survey, it is important to carefully plan the route and identify any potential obstacles that may be encountered. This will help in coming up with strategies to overcome them.
2. Communication: Effective communication among team members is essential in overcoming obstacles. Clear instructions and coordination can help in navigating around obstacles and ensuring the survey is completed successfully.
3. Problem-solving skills: Team members should be equipped with problem-solving skills to quickly address any obstacles that may arise during the survey. This may involve finding alternative routes, using different surveying techniques, or seeking assistance from others.
4. Flexibility: It is important to be flexible and adaptable when faced with obstacles. Being open to changing plans or adjusting surveying methods can help in overcoming challenges and completing the survey successfully.
5. Use of technology: Utilizing advanced surveying equipment and technology can help in overcoming obstacles more efficiently. Tools such as GPS, drones, and laser scanners can provide accurate data and help in navigating around obstacles.
6. Safety precautions: Safety should always be a top priority when overcoming obstacles in a chain survey. Team members should be trained in safety procedures and use appropriate protective gear when working in challenging conditions.
By following these strategies, survey teams can effectively overcome obstacles in a chain survey and ensure accurate and reliable results.

Overcoming Obstacles in Chain Surveying
1. Natural Obstacles:
- Water bodies: Use a transit and stadia rod for indirect measurements.
- Dense vegetation: Clear a path or use a level and staff to establish a sightline.
- Steep terrain: Divide the slope into segments and use slope corrections or a clinometer.
2. Artificial Obstacles:
- Buildings: Use building plans or aerial images to determine dimensions and offsets.
- Roads: Cross perpendicularly and use triangulation or intersection to locate points.
- Power lines: Avoid obstructing them. If necessary, request permission for temporary relocation.
3. Survey Measurement Techniques:
a. Offset Measurements:
- Use an offset rod or chain to measure perpendicularly from a base line to an obstructed point.
b. Oblique Measurements:
- Measure the angle of obliquity using a compass or theodolite and apply trigonometric calculations to determine the horizontal distance.
c. Intersection Method:
- Measure angles to the obstructed point from two known points. Calculate the intersection using angle intersections.
d. Triangulation Method:
- Create a triangle with the obstructed point as one vertex and measure all sides and angles. Use trigonometric calculations to determine the distance to the point.
4. Technology:
- Total stations: Use electronic distance meters and angle sensors to measure obstacles indirectly.
- GPS receivers: Record the coordinates of accessible points and calculate the position of obstacles using triangulation or intersection.
- Laser scanners: Capture 3D point clouds that can be used to identify and compensate for obstacles.
5. Other Considerations:
- Safety: Prioritize safety when working around obstacles.
- Accuracy: Use appropriate measurement techniques and instruments to ensure accuracy.
- Documentation: Record all measurements, obstacles encountered, and the methods used to overcome them for future reference.
- Communication: Coordinate with landowners, utilities, and contractors to minimize disruptions and ensure safety.
