Geodetic Surveying & Land Topography
We provide certified geodetic surveys, topographic profiling, and boundary demarcation for civil engineers, land developers, and municipal registries. Our work focuses on rugged terrain, rural drainage planning, and legally defensible property lines.
First-order horizontal and vertical control using static GNSS and precise leveling. We establish permanent monuments with sub-centimeter accuracy for large-scale infrastructure projects.
High-density point cloud capture with robotic total stations across steep slopes and seasonal creek beds. Deliverables include digital terrain models, cross-sections, and contour maps for drainage design.
Certified land boundary surveys based on historical deed research and field measurement. We set permanent brass monuments and prepare maps for municipal register documentation.
Serving civil engineers, land developers, and municipal land registries across rugged and rural terrain.
Licensed geodesists and field technicians with decades of combined experience in boundary law, topographic mapping, and geodetic control.
Lead Geodesist
Licensed professional surveyor with 18 years in geodetic control networks and cadastral mapping. Managed over 120 km of drainage corridor surveys in mountainous terrain.
Senior Topographic Technician
Specializes in high-density point cloud collection with robotic total stations. Lead field crew on the Valle Verde drainage corridor and three municipal boundary projects.
Boundary & Legal Survey Specialist
Expert in historical deed research and metes-and-bounds reconstruction. Resolved three long-standing parcel disputes in Cerro Alto and prepared 45 certified boundary maps for municipal registration.
All team members carry professional liability insurance and participate in annual continuing education through the International Federation of Surveyors.
From a single total station to a trusted land surveying firm — key milestones that shaped Roughapproximation.
Founded by two geodetic engineers in a small office with one used total station and a leased GPS receiver. The first contract was a boundary survey for three adjacent farm plots in the outskirts of the city. That job paid for the first month’s rent and established our reputation for meticulous fieldwork.
Won the topographic survey contract for a 12 km rural drainage corridor in Valle Verde. The project required over 8,000 elevation points across steep slopes and seasonal creek beds. Delivering a digital terrain model with 50-meter cross-section profiles opened the door to municipal infrastructure work.
Hired a dedicated legal surveyor and invested in dual-frequency GNSS receivers. That year we completed the Cerro Alto boundary demarcation — 45 parcels with three long-standing disputes resolved through historical deed research and precise measurement. The municipal registry approved the submission without corrections.
Established a first-order geodetic control network for the Llanos del Sol solar farm — 12 permanent monuments over 200 hectares with horizontal accuracy better than 5 mm. The network became the foundation for all subsequent staking of solar rows, roads, and substations. This project cemented our capability in large-scale infrastructure layout.
Added a second robotic total station and upgraded to a cloud-based processing pipeline. The team grew to eight field surveyors and two office technicians. Today we handle simultaneous projects across three regions, delivering GIS-ready data and certified boundary maps directly to municipal registries and engineering firms.
