Aerial Volumetric & General Survey

Historically, volumetric survey were done with somewhat manual approach, theodolites used with someone walking over stockpiles taking spot measurement. Modern Aerial Survey techniques utilizing PPK Geo-referenced Photogrammetry are replacing these old method for many compelling reasons.

With PPK Aerial Survey Method can be provide the result equivalent to 368.400 datum points and materially more accurate with tolerance which only around +/-1%.

For reporting, we provide computer generated 3D models with down to 3 cm XYZ, which processed with Digital Evaluation Models (DEM’s), it’s not just suitable for stockfiles, but also suitable for volume survey and modelling quarries and open pit mines.

PT. Gistek Marco Indonesia, provides Non-Destructive Test and Welding Inspection services for a diverse range of industries. We help you to ensure the reaility , safety and integrity of products, equipments or plant assets with our NDT services.

NDT Services

Ultrasonic Test, these method can be performed on all type of materials and its application include :

Flaws detection such as inclusions, cracks and porosity. your

Determining the thickness of test objects, particulary in erossion or corrosion monitoring.

Magnetic Particle Test, these method can detect surface & subsurface discontinuities in Ferromagnetic matrials. These method is widely used in all industry sectors to inspect a variety of products and engine components (Castings, Forgings and Weldments).

Liquid Penetrant Test, also known as Dry Penetrant Test, these method used to located surface breaking flaws such as cracks, porosity, laps, seams and other surface discontinuities. LPT can be applied to both Ferrous and Non Ferrous matrials (Metals, Plastics or Ceramics).
