What is drone mapping?

Drone mapping (UAV photogrammetry) captures hundreds of overlapping aerial photos of a site and processes them into survey products: a georeferenced orthophoto (a true-to-scale aerial map), a dense point cloud, contour lines and a digital terrain model. Combined with ground control points measured by GNSS and verified by a Geodetic Engineer, the result reaches accuracy suitable for planning, design and volume computations, over areas that would take weeks to survey on foot.

When do you need it?

  • Large properties and estates: Farms, haciendas, resorts and multi-hectare family land, where a complete conventional survey would be slow and costly, and where an up-to-date aerial map supports planning and negotiation.
  • Site development and master planning: Developers and designers get terrain plus current ground conditions (vegetation, structures, roads, waterways) in one dataset.
  • Quarry and stockpile volumes: Periodic flights measure extracted and stockpiled volumes accurately, without stopping operations.
  • Construction progress monitoring: Repeat flights document as-is site conditions over time for owners, lenders and contractors.
  • Difficult or hazardous terrain: Steep slopes, tidal flats, dense growth or unstable ground. The drone maps what a field crew cannot safely walk.

When is it not the right tool?

  • Boundary re-establishment: Property corners for legal purposes are set on the ground by a relocation survey, not from the air. Drone output supports, but does not replace, the legal survey.
  • Small urban lots: For a few hundred square meters, a total station or GNSS crew is faster, cheaper and (under trees and beside tall structures) often more accurate.
  • Heavily forested ground: Standard photogrammetry maps what the camera sees. Under closed canopy, the ground surface requires other methods; discuss the site honestly at quotation stage.
⚠️ Regulatory note: Drone operations in the Philippines are regulated by the Civil Aviation Authority of the Philippines (CAAP). Commercial survey flights require compliance with CAAP's RPAS rules (including registration and operator/controller certification) and some areas (near airports, no-fly zones) require specific clearances. A professional operator handles these permissions; flights that cannot be legally cleared are not flown.

How does the process work?

01

Request and flight plan

Send the site location, approximate area and the products you need (orthophoto, contours, volumes). The Geodetic Engineer replies with a price in pesos (₱), the expected accuracy and a schedule within 24 hours.

02

Ground control

Before the flight, ground control points are set and measured with survey-grade GNSS tied to PRS92 control. This is what turns pretty pictures into survey data.

03

Flight

The drone flies the site in a programmed grid at the altitude and overlap the accuracy requires, under CAAP rules and with any needed clearances in place.

04

Processing and delivery

Photos are processed into the orthophoto, point cloud, contours and terrain model, checked against the ground control. You receive the products in standard formats (GeoTIFF, DWG, PDF; point data on request), certified by the PRC-licensed Geodetic Engineer.

What to ask before hiring

  • Will ground control points be used? Accuracy claims without GNSS-measured ground control are marketing, not surveying. Ask how accuracy will be verified and reported.
  • Is the operation CAAP-compliant? Registration, certification and any airspace clearances are the operator's job, but they are your project's risk if skipped.
  • Who certifies the output? For survey-grade deliverables, the processing and quality control should be under a PRC-licensed Geodetic Engineer, especially if the products will support official submissions.
⚠️ Specifications vary by project. The free quotation is the moment to agree accuracy, products and formats.

What's included?

  • Volume computations for quarries and stockpiles, where requested
  • Accuracy report and certification by a PRC-licensed Geodetic Engineer

Frequently asked questions

How much does a drone survey cost in the Philippines?+
It depends on the area, terrain, required accuracy, deliverables and location. Request a free quotation and you will receive an exact price in pesos within 24 hours, with no obligation.
How accurate is drone mapping?+
With proper ground control measured by survey-grade GNSS, orthophotos and terrain models typically reach centimeter-to-decimeter accuracy, depending on flight altitude, camera and terrain. The achievable accuracy for your site is stated in the quotation and verified in the accuracy report.
Can a drone survey be used for titling or boundary disputes?+
Drone products support these processes (as base maps and context) but legal boundary work (relocation, subdivision, titling surveys) rests on ground measurements by a licensed Geodetic Engineer, processed through the DENR. The two are often combined: the drone maps the whole site, the ground crew fixes the legal corners.
How large an area can be flown?+
From a single hectare to hundreds of hectares across multiple flights. Large sites are flown in blocks over several days; the quotation includes the flight plan and timeline.
Is the quotation free?+
Yes, with no obligation. Send the site details and the products you need, and you will receive a price and schedule within 24 hours.
