What is GPS & RTK Surveying?
GPS and Real-Time Kinematic (RTK) surveying represents the highest precision positioning technology available for drone-based geospatial work. While standard GPS provides accuracy within several meters, RTK technology leverages real-time corrections to achieve ±2cm horizontal and ±3cm vertical accuracy—transforming drone surveys into professional surveying tools suitable for legal boundary documentation and construction staking.
Our RTK-equipped drones utilize the DJI D-RTK 2 base station system, which establishes a local reference frame and broadcasts real-time differential corrections to the airborne platform. Every waypoint the drone passes through is recorded with centimeter-level precision, creating survey-grade geospatial data directly compatible with Costa Rican cadastral standards.
The RTK Advantage Over Standard GPS
- Real-Time Corrections: Base station broadcasts differential corrections, eliminating post-processing delays
- Centimeter Accuracy: ±2cm horizontal, ±3cm vertical—suitable for legal surveys and staking
- Faster Data Collection: No need for hours of post-processing with differential corrections
- Direct Integration: RTK points are immediately usable in CAD, GIS, and surveying software
- Weather Flexibility: Functions effectively in many weather conditions without requiring sky exposure during processing
- Legal Recognition: Meets Costa Rican standards for boundary documentation

RTK Surveying Applications in Costa Rica
Boundary & Property Surveys
Establish precise property boundaries for legal documentation and dispute resolution. RTK accuracy meets requirements for Plano Catastro registration and title verification.
Construction Staking
Mark building corners, utilities, and grade reference points with centimeter precision. Reduce surveyor visits and accelerate construction schedules.
Plano Catastro Compliance
Generate survey-grade boundary documentation meeting Costa Rican cadastral standards. Legal property registration requires precise geospatial data; RTK delivers this directly.
Infrastructure Mapping
Survey utility corridors, power lines, and water systems with precise positioning. Track infrastructure assets for maintenance planning and compliance.
Road & Grade Establishment
Mark alignment centerlines, grade elevations, and cross-sections for road construction. Precise vertical accuracy ensures correct grade establishment.
Easement & Right-of-Way
Identify and document easements, utility corridors, and property access rights. Survey-grade accuracy supports legal documentation and dispute prevention.

Costa Rican Plano Catastro Standards
Property registration in Costa Rica requires survey-grade documentation meeting Plano Catastro (cadastral plan) standards. Our RTK surveying delivers the precision and legal recognition required:
What is Plano Catastro?
Plano Catastro is the Costa Rican cadastral survey requirement—a precise property boundary survey that must be conducted by licensed surveyors or approved mapping providers. RTK drone surveying is recognized as an approved method when paired with proper control points and methodology documentation.
Our Plano Catastro Process:
- Property Identification: Review existing property documents and identify survey area
- Base Station Setup: Establish RTK base station with reference to known control points or satellite positioning
- RTK Survey Flight: Drone surveys property boundaries with centimeter-level real-time accuracy
- Corner Marking: Property corners recorded with full position and elevation data
- Documentation Package: Complete survey report with methodology, accuracy assessment, and legal metadata
- Cadastral Registration: Deliver survey package suitable for Costa Rican property registration
Why RTK for Plano Catastro?
Legal Recognition
RTK surveying is recognized by Costa Rican authorities as meeting cadastral survey standards when properly documented.
Rapid Documentation
Survey completion in days rather than weeks. Faster property registration and legal clarity.
Lower Cost
Significantly less expensive than traditional land surveying while maintaining legal validity.
Complete Record
Aerial orthomosaics provide visual documentation complementing traditional boundary surveys.

Frequently Asked Questions
Standard GPS accuracy depends on atmospheric conditions and satellite geometry, typically achieving 2-5 meter accuracy. RTK uses real-time corrections from a base station to eliminate atmospheric errors, achieving ±2cm accuracy. For surveying applications, RTK is the only appropriate technology.
Yes. RTK drone surveying is recognized as an approved cadastral survey method when conducted with proper methodology, control point documentation, and accuracy verification. We prepare all surveys for legal property registration meeting Costa Rican standards.
Typical RTK effective range is 5-10km depending on terrain and radio signal propagation. For larger properties or remote areas, we deploy additional base stations to maintain centimeter accuracy across the entire survey area.
RTK positioning requires clear sky visibility for satellite signals. Heavy cloud cover and rain can degrade accuracy. We monitor weather conditions and schedule surveys during optimal windows. Most Costa Rican locations offer adequate clear-sky opportunities for surveying.
We deliver all surveys in CRTM05 (Costa Rican Transverse Mercator 2005)—the official Costa Rican projection system. This coordinate system is required for Plano Catastro registration and all official property documentation.
Flight time depends on property size. A typical 5-hectare property requires 15-30 minutes of flight time. Total site time including base station setup and verification usually ranges 2-4 hours. Data processing and report generation add 24-72 hours depending on complexity.
