This layout ensures a clear workflow, helping surveyors navigate complex tasks easily.

2. Core Functionalities

Photo and Video Capture

• Allows surveyors to document site conditions or specific features.
• Metadata such as GPS coordinates, elevation, heading, and accuracy is embedded automatically.
• Useful for creating a visual record of landmarks or boundaries.

Measurement Tools

• Tools for:
  • Distance Measurement: Accurately measures distances between points.
  • Angle Measurement: Calculates angles, critical for boundary and topographic surveys.
  • Height Measurement: Measures the elevation of objects, essential for slope analysis.
  • Area Calculation: Calculates the area of a defined polygon, useful for parcel surveys.
• The measurement overlay visualizes real-time data, making it easier for trainees to interpret results.

Augmented Reality (AR) Features

• Interactive AR overlays for 3D modeling and visualization of terrain or structures.
• Allows surveyors to simulate and plan on-site construction or modifications.
• Offers tools for rotating, layering, and fine-tuning AR objects.

Integrated Mapbox

• Provides a satellite view with 3D terrain and building models.
• Displays real-time GPS location, ensuring spatial awareness.
• Allows users to interact with the terrain, identify features, and integrate them into their survey workflow.

Metadata Display

• GPS coordinates, elevation, heading, and measurement accuracy are displayed prominently.
• Enables quick cross-referencing with survey maps and ensures data reliability.

3. Data Management

• Secure Storage:

  • Encrypts and saves survey data locally using IndexedDB.
  • Ensures data integrity and privacy.

• Collaboration and Sharing:

  • Uses WebSockets and PeerJS for real-time collaboration, enabling teams to share measurements and AR models instantly.
  • Facilitates seamless communication between trainees and mentors or colleagues.

• Image and Measurement Saving:

  • Photos and associated metadata are saved in a structured format, allowing easy retrieval and analysis.

4. Advanced Features

Camera Integration

• Accesses high-resolution camera capabilities for detailed site documentation.
• Uses environmental-facing cameras to maximize utility in outdoor conditions.

Real-Time Updates

• Regular updates to GPS coordinates ensure the accuracy of moving or dynamic surveys.
• Integration with device orientation for AR improves usability in uneven terrain.

3D Terrain Analysis

• Utilizes Mapbox's 3D terrain and building layers for advanced site visualization.
• Enhances understanding of complex terrains, which is crucial for topographic surveys.

5. Practical Applications for a Land Surveyor in Training

• Boundary Surveys: Measure distances and angles with precision, ensuring boundary lines are accurate.
• Topographic Surveys: Utilize height and area tools to map terrains and calculate slopes.
• Construction Planning: Use AR to visualize and plan structural layouts.
• Geodetic Surveys: Record and analyze geospatial metadata like GPS and elevation.
• Team Collaboration: Share findings with mentors or teams in real-time for feedback or collaborative decisions.

6. Learning Benefits for Trainees

• Hands-On Experience: The tool provides an interactive platform to learn surveying techniques in real-world scenarios.
• Real-Time Feedback: Enables trainees to validate measurements and techniques on-site.
• Enhanced Understanding: AR and 3D visualizations simplify complex concepts, making them more accessible.
