Topographic Accessories

Sisgeo’s Topographic Accessories are specialized components designed to support precise optical monitoring of settlement and structural movement. These accessories include:

• Reference bolts with threading to securely mount optical targets.

• Prisms and mini-prism assemblies (e.g., GMP104) offering performance akin to Leica mini-prisms.

• Versatile rotary targets mounted on threaded bars or L‑brackets for flexible positioning.

• Aluminum brackets allowing easy adjustment and stable alignment for 3D surveying tasks.

Ideal for establishing consistent topographic benchmarks, these accessories seamlessly integrate with settlement monitoring setups to facilitate optical survey checks.

Applications of Topographic Accessories

1. Settlement and Heave Monitoring - Used to measure vertical displacement (settlement or uplift) in soils, embankments, or foundations by placing optical targets at known locations.
2. Slope Stability Monitoring - Deployed on natural or engineered slopes to track surface movement over time.
3. Dams and Embankments - Installed on the crest and body of earth or concrete dams to monitor structural deformation or settlement.
4. Excavation and Tunneling Projects - Placed around deep excavations, shafts, or tunnel portals to monitor ground or wall movement.
5. Bridges and Elevated Structures - Optical targets fixed on bridge decks or piers for monitoring deflections, tilting, or long-term deformation due to traffic or load.
6. Building Deformation Survey - Installed on building façades, roofs, or foundations to detect subtle movements or settlement in urban infrastructure, especially near construction zones.
7. Rail and Road Infrastructure - Used to monitor track bed or pavement movement in response to traffic loads, soil subsidence, or temperature changes.
8. Reference Benchmarking in Geodetic Networks - Serves as stable optical reference points in long-term geodetic or deformation monitoring networks.
