Differential Global Positioning System (DGPS) surveying is a technology that enhances the accuracy of GPS measurements by correcting the inherent errors in GPS signals. It achieves this by using a network of ground-based reference stations that transmit corrections to GPS receivers.
Precise Positioning:
Accurate positioning of points for mapping, surveying, and construction.
• Real-time kinematic (RTK) DGPS provides centimeter-level accuracy.
Geographic Information Systems (GIS):
• Creating accurate digital maps and geographic databases.
• Analyzing spatial data for various applications like urban planning, environmental monitoring, and resource management.
Hydrographic Surveying:
• Mapping underwater features like shoals, reefs, and underwater pipelines.
• Ensuring safe navigation for ships and boats.
Cadastral Surveying:
• Defining and mapping land boundaries with high precision.
• Resolving land disputes and property boundary issues.
Geodetic Surveying:
• Establishing control points for large-scale mapping and surveying projects.
• Monitoring land movement and deformation.
Mobile Network Survey:
• Optimizing mobile network coverage and performance.
• Identifying areas with weak signal strength and planning network expansion.
Forestry:
• Mapping forest boundaries and creating detailed forest inventories.
• Monitoring deforestation and illegal logging activities.
• Assessing forest health and biodiversity.
