Boundary demarcation, the process of defining and marking land boundaries, is crucial for various purposes, including land ownership, property rights, and resource management. To achieve accurate and efficient boundary demarcation, a combination of technologies, including GPS, drones, and DGPS, can be employed.
• Standard GPS: Provides approximate location data, useful for general mapping and navigation.
• Differential GPS (DGPS): Offers significantly improved accuracy by correcting GPS signals using ground-based reference stations.
• Real-Time Kinematic (RTK) GPS: Delivers centimeter-level accuracy for precise boundary definition.
• Aerial Photography and Videography: Captures high-resolution images and videos of the area to be surveyed.
• Digital Surface Models (DSMs) and Digital Terrain Models (DTMs): Generates detailed 3D models of the terrain, aiding in boundary analysis and visualization.
• Orthomosaics: Creates accurate, georeferenced mosaics of aerial images, providing a comprehensive overview of the area.
• Precise Mapping: Accurately delineates forest boundaries, including complex areas like riverine forests and fragmented landscapes.
• Monitoring Deforestation: Tracks changes in forest cover over time.
• Illegal Logging Prevention: Supports law enforcement efforts by providing evidence of illegal logging activities.
• Urban Planning: Defines urban growth boundaries and identifies areas for development.
• Land Use Planning: Maps different land use zones and assesses their suitability for various activities.
• Infrastructure Development: Supports the planning and implementation of infrastructure projects, such as roads, railways, and utilities.
• Agricultural Land: Defining and mapping agricultural land parcels for efficient land management.
• Water Bodies: Delimiting water bodies like lakes, rivers, and reservoirs.
• Protected Areas: Mapping and monitoring protected areas, such as national parks and wildlife sanctuaries.
By integrating GPS, drone, and DGPS technologies, surveyors can achieve precise boundary demarcation, ensuring accurate land records, efficient resource management, and effective environmental conservation.
