Myzox TH400 vs 50cm, 100cm & 150cm GCP Target Malaysia Which Ground Control Point Should You Buy?

Myzox TH400 vs 50cm, 100cm & 150cm GCP Target Malaysia Which Ground Control Point Should You Buy? Content Myzox TH400 vs Large GCP Targets for Drone Survey Malaysia 395mm Professional Myzox GCP vs 50×50cm, 100×100cm & 150×150cm Drone Survey Targets If you are buying Ground Control Point targets for drone mapping, one question quickly appears: Should I buy a professional compact GCP such as Myzox TH400? or: Should I buy a larger 50cm, 100cm or 150cm reusable GCP target? These products should not be compared simply as: EXPENSIVE vs CHEAP The more useful comparison is: PROFESSIONAL PURPOSE-BUILT DESIGN vs LARGE VISUAL FOOTPRINT QUICK ANSWER: Myzox TH400 is the stronger choice when you value a compact purpose-built survey accessory with a defined centre datum hole, corner fixing holes and design features intended for aerial photography. Larger 50cm, 100cm and 150cm targets become attractive when physical image footprint is the main priority. TH400 = PROFESSIONAL DESIGN 50 / 100 / 150cm = SIZE & VISIBILITY OPTIONS The Four GCP Options GCP TargetApprox.

Myzox designed TH400 specifically as a Ground Control Point for drone mapping. The TH400 series includes: TH400-BW Black / White TH400-BY Black / Yellow TH400-BWR White Circle / Black The published TH400 design includes: 395 × 395 × 1mm size PP construction Approx. 150g per sheet Centre datum-point hole Four corner fixing holes and surface/material treatment intended to reduce halation during aerial photography. This is what separates TH400 from a generic large printed target. Myzox TH400's Biggest Advantage: Defined Survey Reference For professional survey work, this is important. The question is not only: span style="color:#000000;">“Can I see the target?” It is: “Can I identify the exact point that was surveyed?” TH400 incorporates a centre datum-point hole. That supports a cleaner relationship between: GROUND SURVEY REFERENCE and IMAGE REFERENCE This is a meaningful professional feature. 50×50cm Target's Biggest Advantage: Portability + More Width The 50cm target is slightly larger in physical width than TH400. Its commercial positioning should be simple: COMPACT GENERAL-PURPOSE GCP It is suitable for users who want: Portable targets Simple deployment Reusable field kit Lower storage requirement provided the planned GSD and imagery make the target sufficiently identifiable. 100×100cm Target's Biggest Advantage: Balance For the broad Malaysian drone-survey market: 100×100cm IS OUR PRACTICAL GENERAL-PURPOSE STARTING OPTION. Why? It gives substantially more visual footprint than a compact target while remaining a manageable general-purpose field size. It can fit: Construction Earthwork Quarry Road Plantation Topographic mapping But this does not mean every project needs a 100cm target. 150×150cm Target's Biggest Advantage: Visual Footprint This is straightforward. 150×150cm = LARGE TARGET Its main selling point should not be: “More accurate.” It should be: “More physical visual footprint.” That distinction protects the technical credibility of the content. Does 150cm Beat Myzox TH400? NO NOT AS A UNIVERSAL STATEMENT. The 150cm target is almost four times the width of the 395mm TH400. That provides a much larger physical footprint. But TH400 provides purpose-designed features that the general target should not be claimed to have unless verified. Therefore: 150cm WINS ON PHYSICAL SIZE while: TH400 WINS ON PURPOSE-BUILT PROFESSIONAL DESIGN Different advantages. Does Myzox TH400 Beat a 100cm Target? Again: NOT UNIVERSALLY. If a professional surveyor says: “I want a compact Myzox target with a defined datum point and purpose-designed fixing arrangement.” TH400 makes sense. If a drone contractor says: “My main concern is getting a larger visible target in my aerial images.” 100cm may make more sense./span> Which One Is More Accurate? This is where MTM should be very clear. YOU CANNOT DETERMINE FINAL DRONE MAPPING ACCURACY FROM GCP TARGET SIZE OR BRAND ALONE. Accuracy also depends on: Ground-coordinate quality GNSS RTK / Total Station procedure GCP distribution GSD Flight geometry Camera Image quality CRS Processing Independent Check Points A RM10 target with a correct coordinate is not automatically inferior to an expensive target in coordinate accuracy. And: A professional target with a wrong coordinate is still wrong control. Where Myzox TH400 Adds Value The professional value is in areas such as: Consistent target design Defined datum point Fixing arrangement Compact form Purpose-built aerial-survey design Myzox surveying ecosystem This can be attractive to: LAND SURVEYORS PROFESSIONAL SURVEY COMPANIES ENGINEERING CONSULTANTS UAV SURVEY TEAMS CONSTRUCTION SURVEY DEPARTMENTS Where 100cm Adds Value 100cm should target a broader group: DRONE SERVICE PROVIDERS CONTRACTORS EARTHWORK COMPANIES QUARRY OPERATORS PLANTATION MAPPING TEAMS UAV OPERATORS NEW DRONE-SURVEY USERS These buyers may primarily want: A LARGE, SIMPLE, VISIBLE GCP TARGET rather than a specialist compact survey accessory. Where 150cm Adds Value 150cm can target users whose planned imagery benefits from more physical visual footprint. Possible scenarios include: Larger sites Coarser planned GSD Conditions where additional target footprint is useful But always evaluate actual flight conditions. DO NOT SELL 150cm BY PROMISING BETTER ACCURACY. Sell it by explaining: MORE VISUAL FOOTPRINT. GSD Changes the Comparison Consider a simplified example. At 2cm/pixel GSD: TargetSimplified Pixels AcrossMyzox TH400 39.5cm≈20 pixels50cm≈25 pixels100cm≈50 pixels150cm≈75 pixels At 5cm/pixel GSD: TargetSimplified Pixels AcrossMyzox TH400 39.5cm≈8 pixels50cm≈10 pixels100cm≈20 pixels150cm≈30 pixels These are idealized geometric examples only. Actual target identification can also be affected by: Blur Exposure Lens Viewing angle Contrast Target pattern Image processing THIS IS WHY TARGET SIZE SHOULD BE MATCHED TO THE FLIGHT NOT CHOSEN FROM BRAND NAME ALONE. Same Altitude Does Not Mean Same Answer Customer A flies at: 100m Customer B also flies at: 100m Do they automatically need the same GCP? NO. Their drones may have different: Sensors Lenses Image resolution Therefore they may produce different GSD. ASK ABOUT GSD OR DRONE/CAMERA WORKFLOW NOT ONLY ALTITUDE. Myzox TH400 for Lower-GSD / Detailed Mapping Where the planned imagery provides enough target pixels and clear target identification, a compact professional GCP can be highly practical. Its compact size means: Easier transport Smaller storage footprint Professional field kit A SMALLER TARGET IS NOT A PROBLEM IF IT REMAINS RELIABLY IDENTIFIABLE. 100cm for General Drone Contractors A drone contractor may not want to calculate every target decision from scratch. For a versatile reusable kit: 100×100cm IS THE MAIN GENERAL-PURPOSE OPTION TO CONSIDER. Then supplement with: 50cm for compact work or 150cm where more visual footprint is required. Should a Professional Survey Company Own Both? This is where the product strategy becomes interesting. YES THERE CAN BE A STRONG CASE FOR HAVING MORE THAN ONE TARGET TYPE. For example: MYZOX TH400 for compact professional cotrol work. plus: 100×100cm for projects requiring larger visual targets. plus potentially: 150×150cm for specific larger-footprint requirements. This turns the purchase from: “Which one should I buy?” into: “WHICH TARGET SHOULD I DEPLOY FOR THIS PROJECT?” One GCP Kit Does Not Need One Size Only A professional field kit could contain: Compact targets General-purpose targets Large targets This allows the survey team to respond to: Different GSD Different surfaces Different flight plans Different project environments MIXED TARGET SIZES CAN BE A PRACTICAL FIELD STRATEGY WHEN USED DELIBERATELY. Myzox TH400 for Construction Choose TH400 where: Compact deployment matters Professional survey-control workflow is already established A clearly defined datum point is desirable The planned imagery provides sufficient target visibility For construction teams already using Myzox accessories: TH400 FITS NATURALLY INTO THE SURVEY FIELD KIT. 100cm / 150cm for Construction Larger targets may be attractive when: The site is visually busy More visual footprint is desirable The drone contractor wants simple target recognition But target stability remains critical. DO NOT LET MACHINERY MOVE THE TARGET AFTER IT HAS BEEN SURVEYED. Which Is Better for Quarry? Quarries have: Large elevation changes Dust Rock Heavy machinery Large mapping areas The decision should consider: GSD Flight height Contrast Target accessibility Safety Target stability A larger target can help with visual footprint. A TH400 can offer a compact purpose-built solution where imaging conditions support it. THERE IS NO UNIVERSAL “QUARRY = 150cm” RULE. Which Is Better for Road Survey? Road projects are long corridors. Target size is only one part of the problem. DISTRIBUTION ALONG THE CORRIDOR IS CRITICAL. Ten expensive TH400 targets clustered at one end are not automatically better than a properly designed control network. Likewise, ten 150cm targets do not fix poor control geometry. CONTROL DESIGN FIRST TARGET PRODUCT SECOND. Which Is Better for Plantation? Plantation mapping has another major issue: CAN THE DRONE SEE THE TARGET THROUGH THE VEGETATION? A larger target can improve footprint in open areas. But: 150cm UNDER DENSE CANOPY IS STILL HIDDEN. Choose open, suitable locations according to the survey plan. Which Is Better for RTK Drone? Both can work. With an RTK drone, a physical target might serve as: GCP or CHECK POINT depending on the project. For independent verification, the main requirement remains: CLEARLY IDENTIFIABLE TARGET + RELIABLE INDEPENDENT GROUND COORDINATE Which Is Better for GNSS RTK? Target size does not determine GNSS accuracy. GNSS establishes the coordinate. The target makes that coordinate visible in the image. Therefore: TH400 + GNSS RTK and 100cm GCP + GNSS RTK can both be valid workflows. GNSS ACCURACY DOES NOT INCREASE BECAUSE THE TARGET IS BIGGER. Which Is Better for Total Station? Same principle. A Total Station measures the ground position according to the project's control methodology. The physical target is for image identification. TH400's defined centre datum design can be particularly attractive for a clean professional reference. But: A LARGER TARGET MAY BE MORE APPROPRIATE WHEN IMAGE VISIBILITY IS THE LIMITING FACTOR.

Instead of: “This one cheapest.” Ask: What drone are you using? What is your planned GSD? What type of project? Construction, quarry, road or plantation? GNSS RTK or Total Station? Do you need GCP or Check Point targets? Then recommend: TH400 / 50cm / 100cm / 150cm based on the workflow. THAT IS A SURVEY-EQUIPMENT SALE NOT JUST SELLING A PIECE OF PRINTED MATERIAL. Frequently Asked Questions Is Myzox TH400 bigger than a 50cm GCP? No. TH400 is approximately 395×395mm, while the 50cm target is 500×500mm. Why buy TH400 if a 100cm target is bigger? Because TH400 offers purpose-built professional design features, including its defined centre datum point, corner fixing holes and aerial-photography-oriented design. The 100cm target's advantage is its much larger physical visual footprint. Is Myzox TH400 more accurate? NOT AUTOMATICALLY. Target design is only one part of the survey workflow. Is 150cm the best GCP? NO. It is the largest of these target-size options, but bigger is not universally better. Which one should a new drone survey company buy first? For broad general-purpose use: 100×100cm is our practical starting option. Professional survey companies may also consider Myzox TH400 as a purpose-built compact GCP. Can I buy different sizes? YES. A mixed GCP kit can provide more flexibility across different GSD, project and visibility conditions.
