Reusable GCP Target for UAV Mapping, Photogrammetry & Construction Survey
Looking for a Ground Control Point (GCP) Target in Malaysia for drone surveying or aerial mapping?
MTM Precision supplies reusable high-visibility GCP targets in 50θ³50cm, 100θ³100cm and 150θ³150cm sizes for professional drone mapping, UAV photogrammetry, construction survey, earthwork measurement and topographic mapping applications.
QUICK ANSWER: A Ground Control Point (GCP) is a clearly identifiable ground target positioned at a known surveyed coordinate. It allows drone imagery to be connected to accurate ground coordinates during photogrammetric processing.

ηΈ For buyers unsure which size to choose, 100 θ³ 100 cm is a practical general-purpose starting option.
The final size should still be selected according to flight altitude, GSD, camera resolution, ground conditions and project requirements.
What Is a Ground Control Point in Drone Surveying?
A Ground Control Point is a physical point on the ground whose coordinates are accurately established.
The target centre may be surveyed using equipment such as:
ι₯ GNSS / RTK Rover
ι₯ Total Station
ι₯ Other appropriate survey control methods
During drone photogrammetry processing, the target is identified in the aerial photographs and associated with its known coordinates.
The purpose of a GCP is not simply to make a mark visible from the air ι₯ it provides a known spatial reference for the mapping workflow.
Why Are GCP Targets Important for Drone Mapping?
Drone photographs alone contain image information.
For survey and mapping applications, the project may also require reliable positioning relative to real-world coordinates.
Properly surveyed and distributed GCPs can support:
ι Georeferencing of aerial imagery
ι Positional control
ι Photogrammetric adjustment
ι Orthomosaic production
ι Digital terrain / surface modelling
ι Construction progress mapping
ι Earthwork and volume survey workflows
GCP measurement quality and placement are more important than simply putting many targets on the ground.
50 θ³ 50cm GCP Target
Compact Size for Easy Field Deployment
The 50θ³50cm GCP target is the smallest of the three available sizes.
Its main advantage is portability.
Suitable considerations include:
Smaller project sites
Suitable low-altitude UAV missions
Construction sites
Localised mapping
Survey teams carrying multiple targets
Projects where compact storage is important
Choose 50θ³50cm only when the target will remain clearly identifiable at the intended GSD and flight parameters.
100 θ³ 100cm GCP Target
Recommended General-Purpose Size
The 100θ³100cm Ground Control Point target offers a strong balance between visibility, portability and practical field handling.
Potential applications include:
ι₯ Drone land survey
ι₯ Construction progress mapping
ι₯ Earthwork survey
ι₯ Topographic mapping
ι₯ Road projects
ι₯ Infrastructure projects
ι₯ Quarry mapping
ι₯ Plantation mapping
For many customers starting with reusable GCP targets, this is the size we would consider first.
150 θ³ 150cm GCP Target
Large Target for Greater Visual Presence
The 150θ³150cm target provides a substantially larger ground marking.
Consider this size when the survey methodology benefits from a larger target that is easier to distinguish in aerial imagery.
Potential applications include:
Larger project areas
Large construction sites
Infrastructure corridors
Quarry sites
Plantation mapping
Projects requiring a larger visible ground target
A larger target improves visibility, but it does not automatically improve survey accuracy.
Accuracy still depends on the complete surveying and photogrammetry workflow.
50cm vs 100cm vs 150cm GCP ι₯ Which Should You Buy?
Choose 50θ³50cm if:
Portability and compact deployment are priorities, and the target remains sufficiently visible under your flight conditions.
Choose 100θ³100cm if:
You need a versatile general-purpose GCP target for regular drone survey work.
Choose 150θ³150cm if:
Your application benefits from a larger and more easily identifiable ground target.
ιΏη
η¬ Important: Bigger GCP Does Not Automatically Mean Better Accuracy
This is an important point for drone surveyors.
GCP target size alone does NOT determine mapping accuracy.
Target selection should consider:
ι₯ Flight altitude
ι₯ Ground Sampling Distance (GSD)
ι₯ Camera resolution
ι₯ Image quality
ι₯ Target contrast
ι₯ Ground surface
ι₯ GCP distribution
ι₯ Coordinate measurement accuracy
ι₯ Photogrammetry processing methodology
A good target must be clearly visible while allowing its exact reference point to be identified consistently in the imagery.
How to Use a GCP Target for Drone Mapping
STEP 1 ι₯ Position the Targets
Distribute the GCP targets around the survey area according to your project methodology.
STEP 2 ι₯ Survey the Coordinates
Measure the reference centre of each target using suitable GNSS/RTK or Total Station equipment.
STEP 3 ι₯ Conduct the Drone Flight
Capture the required aerial imagery.
STEP 4 ι₯ Identify the GCPs
Locate the corresponding targets within the captured images.
STEP 5 ι₯ Enter the Surveyed Coordinates
Assign the measured coordinates to the corresponding GCPs.
STEP 6 ι₯ Process & Evaluate
Complete the photogrammetric workflow and assess the output according to the project's accuracy requirements.
GCP vs Check Point ι₯ What Is the Difference?
This distinction is important.
GCP ι₯ Ground Control Point
A known coordinate point that is normally used as control within the photogrammetric adjustment.
CHECK POINT
A separately surveyed point that is normally kept independent from the adjustment and used to evaluate the resulting accuracy.
A Check Point is therefore not simply another name for a GCP.
Professional drone survey projects may use both depending on the required methodology.

Frequently Asked Questions
What sizes are available in Malaysia?
MTM Precision offers:
50 θ³ 50 cm
100 θ³ 100 cm
150 θ³ 150 cm
Which GCP size is recommended for general use?
100θ³100cm is a practical general-purpose starting size because it provides a useful balance between target visibility and field portability.
However, the correct size depends on the project's GSD, altitude, camera and operating conditions.
Can these GCP targets be reused?
Yes. They are designed as portable targets that can be collected and reused, subject to their physical condition.
Can GCPs be used with RTK drones?
Yes.
Depending on the required accuracy and methodology, GCPs and independent checkpoints can still form part of an RTK drone mapping workflow.
Do I need RTK/GNSS to use a GCP?
If the GCP is intended to provide accurate control coordinates, its reference position needs to be established using an appropriate surveying method, such as GNSS/RTK or Total Station.
Does using more GCPs always improve accuracy?
No.
The quality and distribution of the control points are critical. Simply increasing the number of GCPs does not guarantee a better result.
