Survey Services
DGPS Land and Drone Survey
Drone survey at GPSCAD Survey Pvt. Ltd. utilizes advanced UAV technology to capture accurate aerial data for land surveying, mapping, and infrastructure projects. Equipped with high-resolution cameras and GPS systems, drones ensure precise and efficient data collection. This method reduces time, cost, and field risks while improving productivity. The collected data is processed into detailed maps, 3D models, and reports, supporting planning, monitoring, and decision-making across various projects and operational areas.
Topography Survey with Total Station
Topography survey using a total station is a precise method to map land features, elevations, and contours. It combines electronic distance measurement and angle calculation to capture accurate field data. The survey identifies natural and man-made features such as boundaries, roads, and structures. Data collected is processed to create detailed maps and contour plans, essential for planning, design, and construction projects, ensuring accuracy, efficiency, and proper site understanding before development.
BOUNDARY SURVEY
We identify and mark exact property boundaries for legal, construction, and ownership purposes. It helps in land purchase, fencing, disputes, and legal verification.
TOPOGRAPHIC SURVEY
We collect detailed information about land features such as levels, slopes, contours, roads, and existing structures. This helps in proper planning and designing of construction and development projects.
We also do survey work for roads and railways. In this, we study land, soil, contour, and topographic.
CONSTRUCTION LAYOUT / SETTING OUT
We transfer design drawings accurately onto the site for correct construction positioning. It ensures buildings, roads, and structures are built in the right location.
AUTOCAD/GIS MAPPING
We create digital maps and databases for land, utilities, and infrastructure. It is useful for planning, management, and smart city development.
CONTOUR SURVEY
We measure land elevation and slopes to create contour maps. It helps in road design, drainage planning, and site development.
DRONE SURVEY
We use drones to capture fast and accurate aerial site data. It is useful for mapping, contouring, and large area surveys.
SOIL TESTING
We analyze soil strength and quality to check suitability for construction. It ensures safe foundation design and strong building structures.
INSTRUMENTS & SOFTWARE
We use modern surveying instruments like Total Station, DGPS, Static GPS, RTK, PPK, and Auto Level for accurate field measurements and leveling work. These instruments help us in boundary surveys, construction layout, and topographic mapping with high precision.
For processing and design work, we use professional software such as AutoCAD, GIS software, and Global Mapper. These tools help in preparing drawings, maps, contour analysis, and land data management.
OBSTACLE LIMITATION SURFACE (OLS)
WGS-84 Coordinate & Elevation Survey
We carry out accurate determination of latitude and longitude in the WGS-84 system along with site elevation (Above Mean Sea Level) using advanced surveying instruments such as DGPS and Total Station, which is essential for AAI NOC approval.
Site / Pre-Feasibility Inspection
We conduct detailed site inspection for surface helipads, rooftop helipads, existing airports, and greenfield airport projects to assess site suitability, surrounding developments, terrain conditions, and aviation safety restrictions, followed by a preliminary feasibility report.
Obstacle & Topographical Survey (OLS Study)
We perform Obstacle Limitation Surface (OLS) surveys to identify all natural and man-made obstacles such as buildings, trees, towers, etc., for surface helipads, rooftop helipads, existing airports, and greenfield airport projects. We also prepare detailed topographical maps, aeronautical charts, and complete survey & cartography drawings required for aviation planning, design, and safety compliance.
Technical Report Preparation
We prepare a detailed technical report including survey data, WGS-84 coordinates, elevation details, obstacle analysis, and recommendations for safe and compliant development as per aviation requirements.
DGPS & Total Station Survey Execution
All surveys are conducted using high-precision DGPS and Total Station equipment to ensure accurate, reliable, and aviation-standard compliant data for all types of airport and helipad related projects.
