High-Precision Surveying in Urban and Rural Areas
Surveying in urban and rural areas is the fundamental basis for any planning, geometric road design, civil infrastructure and survey networks. Accurate land surveying prevents legal problems and ensures the structural safety of any development.
AMD-TOPOGRAFIA, LDA. applies the most modern market techniques to perform demarcation, property subdivision and cartographic measurements with maximum accuracy, providing complete geo-referenced reports for legal certification and engineering project support.
Cadastral and Rural Operations
- Land plots: Measurement, demarcation and subdivision for commercial transactions or partitions.
- Property subdivision: Orderly division of land plots in urban areas according to local guidelines.
- Agricultural plot fragmentation: Precise delimitation of productive rural plots for crop optimization.
- Area rectification for IPGUL: Adjustment, validation and legalization of property boundaries within the urban area of Luanda.
Applied Field Engineering
- Planimetric surveys with GNSS receivers and Total Stations.
- Setting out and dimensional monitoring of civil works.
- Cadastral measurements to protect territorial property rights.
- Volume calculations and earthwork monitoring.
- Topographic surveys for energy transmission lines.
- Detailed architectural surveys of historic and modern buildings.
- Land subdivisions, street layouts and general urban infrastructure.
We develop civil engineering and infrastructure projects using cutting-edge methodologies, including geometric road design, water supply and sanitation network sizing, and sustainable urban planning. Our team ensures each project strictly complies with current technical standards and the client's specific requirements.
- Geometric design of urban roads and rural roads
- Development of Agricultural Development Projects
- Sizing and routing of hydraulic infrastructure
We capture physical reality with millimetre precision using laser 3D scanning equipment (Terrestrial and Mobile Laser Scanner). We generate detailed point clouds, digital models and BIM (Building Information Modeling) for rehabilitation, structural control and interactive three-dimensional visualization of buildings, terrain and industrial facilities.
- Dense point clouds and high-chromatic precision registration
- Structural 3D CAD models and complex architectural surfaces
- Project integration and coordination in a BIM environment
We perform aerial surveys using Drones (UAVs) equipped with high-resolution cameras to produce high-precision orthophotomaps, Digital Terrain Models (DTM) and Surface Models (DSM). These solutions support land use planning, environmental monitoring and volume calculations in construction and mining projects.
- Thematic mapping and digital geographic terrain maps
- Specialized photogrammetric processing for orthomosaics
- Three-dimensional terrain digital modelling (DTM/DSM)
We establish high-precision support geodetic networks through GPS/GNSS satellite positioning (Static/RTK) and precision geometric levelling. We ensure rigorous cartographic framing of all surveys, essential for property cadastre and large-scale linear infrastructure.
- Geodetic networks supporting linear infrastructure works
- Static and kinematic georeferenced GNSS positioning
- High-precision geometric levelling for vertical elevation control
Why preventive maintenance is essential
Topography equipment requires centimetric to millimetric precision. Any deviation compromises measurements, generating rework and delays. Preventive maintenance guarantees:
Precisão Contínua
Continuous precision in surveys and measurements.
Alta Produtividade
Less downtime in critical works and projects.
Maior Vida Útil
Longer equipment lifespan.
Segurança Total
Data security with updated firmware and configuration backups.
