Drone (UAV) Survey and Mapping in Saudi Arabia

UAV mapping for orthophotos, contours, surface models and stockpile volumes across Saudi Arabia.

Large sites, long corridors and active quarries can take days to survey on foot. A drone survey captures the whole area from the air in a fraction of the time and turns it into accurate maps, surface models and volumes. EarthScape Technologies provides drone (UAV) surveys across Saudi Arabia (KSA), including Riyadh, Jeddah, Dammam, Makkah and Madinah, from our office in Riyadh.

What Is a Drone Survey?

A drone survey uses an unmanned aerial vehicle fitted with a high-resolution camera to capture many overlapping photographs along a planned flight path. Photogrammetry software matches common points between the images to build a 3D model of the ground and everything on it. That model is used to produce georeferenced orthophotos, surface models, contours and measurements.

To tie the results to real-world coordinates, our surveyors place and measure ground control points (GCPs) with GNSS. Independent check points confirm how well the model fits the ground.

Our Method and Equipment

When Do You Need a Drone Survey?

Site appraisal and feasibility studies for new developments
Topographic mapping of large or hard-to-access areas
Earthworks planning and cut-and-fill calculations
Stockpile and quarry volume measurement
Regular progress monitoring and visual records
Corridor mapping for roads, pipelines and power lines

Deliverables

Georeferenced orthophoto mosaics (for example GeoTIFF)
Digital surface models (DSM) and digital terrain models (DTM)
Contour plans at agreed intervals
Dense point clouds and 3D mesh models
Stockpile and earthwork volume reports
AutoCAD and Civil 3D drawings prepared by our CAD drafting team
A survey report covering control, checks and limitations

Accuracy and Quality

Drone survey accuracy depends on flying height, camera quality, image overlap, ground control and the surface being mapped. Bare, textured ground maps well, while vegetation, water, reflective roofs and very uniform surfaces are harder. We agree the accuracy you need before flying, design control to match, and report the results of independent checks so you know how far the data can be relied on.

Benefits of Drone Surveys

Fast coverage of large areas with fewer days on site
Less need for people to walk on stockpiles, slopes or active work areas
A complete visual record of the site at the date of the flight
Repeatable surveys for progress and volume tracking

Planning

Every project starts with a review of the area, the required outputs and the site constraints. We plan each flight around site permissions, safety and the airspace rules that apply to the location, and coordinate with site management before flying.

Ground Control and Flight

Our surveyors establish ground control with GNSS, then fly the planned mission with suitable overlap and flying height to achieve the required ground sample distance (GSD).

Processing

Our data analysts process the imagery, check the model against control and check points, and edit the surface to remove vegetation, vehicles and other objects where a bare-earth model is needed.

Combining Methods

Drone data works well with our other services. Where you need hard detail such as curbs, manholes or levels under structures, we combine aerial mapping with a ground topographic survey. For buildings and complex structures, 3D laser scanning adds detail the camera cannot see.
