Why this stack
The same photogrammetry pipeline we license to enterprise — flown for you.
PIX4D is the photogrammetry standard against which every other tool is measured. Emlid Reach is the RTK GNSS pole used by surveyors across Southeast Asia. Combined, they deliver a 1–3 cm orthomosaic, a checkpoint-validated DSM, a colourised point cloud and a textured 3D mesh — repeatable on every flight.
Easepect supplies the brands, runs the flights or trains your team, and signs off the final deliverable in partnership with a licensed surveyor when the project requires it.

Workflow
Six steps from brief to deliverable.
01
Plan
Mission design — target GSD, overlap (75% / 75% standard), altitude, GCP layout. Easepect specs the flight to the accuracy class up-front.
02
Permit
CAAS Activity Permit and airspace coordination near Changi / Seletar / Paya Lebar / Tengah. Easepect handles the regulatory paperwork.
03
Capture
Drone imagery + RTK ground control points captured against SiReNT corrections. Live QA on coverage during the flight.
04
Process
Photogrammetry in PIX4Dmatic, PIX4Dmapper or PIX4Dcloud. Independent checkpoint validation against RTK measurements.
05
Vectorise
PIX4Dsurvey turns the point cloud into CAD-ready breaklines, kerbs, manhole rims, road furniture and feature attributes.
06
Deliver
Hand-delivered GeoTIFF / LAS / DWG / KMZ bundle plus a PIX4Dcloud share link for stakeholders.
Specifications
What to expect on every project.
| GSD | Typical 1–3 cm/px depending on payload and altitude. Sub-cm achievable on close-range terrestrial captures. |
|---|---|
| Absolute accuracy | 1–3 cm horizontal, 2–5 cm vertical with well-distributed RTK GCPs. 1–3 m without GCPs (GNSS EXIF only). |
| Coordinate systems | SVY21 (EPSG:3414), Kertau RSO, ITRF, WGS84 UTM zones, custom project grids. |
| Outputs | GeoTIFF orthomosaic, DSM / DTM, LAS / LAZ point cloud, OBJ / FBX / GLB textured mesh, DXF / SHP / GeoPackage vectors, PIX4Dcloud share link. |
| Capture rate | Typical 80–200 ha/day single drone, depending on altitude, GSD and overlap. |
| Turnaround | 3–5 working days flight-to-deliverable for <100 ha. 24-hour express on request. |
| Networks | SiReNT (Singapore), MyRTKnet, RTKnet.id, plus customer-supplied private base stations. |
| Compliance | CAAS Operator Permit + UAPL pilots + per-flight Activity Permits. Full third-party + equipment insurance. |
Applications
Where drone mapping wins the job.

- Insurance / forensic post-incident damage assessment.
FAQ
Common questions.
How accurate is drone photogrammetry? +
With well-distributed RTK GCPs the absolute accuracy is typically 1–3 cm horizontal and 2–5 cm vertical against checkpoints. Without RTK GCPs you are limited to GNSS EXIF accuracy — typically 1–3 m. Easepect specs the GCP density and distribution to your accuracy class up-front.
How fast is turnaround? +
For most photogrammetry projects under 100 ha, deliverables ship in 3–5 working days from the flight date. 24-hour express is available where the schedule justifies it. LiDAR projects add 2–3 days for classification and DTM generation.
What output formats do you deliver? +
Orthomosaic in GeoTIFF / ECW / MrSID, DSM / DTM in GeoTIFF / ASCII grid, point cloud in LAS / LAZ / E57, mesh in OBJ / FBX / GLB, vectors in DWG / DXF / SHP / GeoPackage / KML, plus a PIX4Dcloud share link for stakeholder review.
Can you fly your own drone or use mine? +
Both. Easepect operates a fleet of DJI M300 / M350 RTK airframes with multispectral, thermal and LiDAR payloads. We also process customer-flown imagery — bring the cards, we ship the deliverable.
Do you handle CAAS permits? +
Yes — Easepect holds the CAAS Operator Permit and our pilots hold UAPL. We handle every per-flight Activity Permit on behalf of clients, including controlled-airspace and BVLOS operations.
What does it cost? +
A typical Singapore mapping flight up to 20 ha with full photogrammetry deliverables sits in the SGD low-four-figure range. Larger sites, BVLOS, multispectral / thermal payloads or LiDAR push pricing higher. Use the on-page mission builder for an instant indicative scope.
